+{
+ Version 1.4361
+ 2003-03-04 - Fixed important bug for simple transparency when using
+ RGB, Grayscale color modes
+
+ Version 1.436
+ 2003-03-04 - * NEW * Property Pixels for direct access to pixels
+ * IMPROVED * Palette property (TPngObject) (read only)
+ Slovenian traslation for the component (Miha Petelin)
+ Help file update (scanline article/png->jpg example)
+
+ Version 1.435
+ 2003-11-03 - * NEW * New chunk implementation zTXt (method AddzTXt)
+ * NEW * New compiler flags to store the extra 8 bits
+ from 16 bits samples (when saving it is ignored), the
+ extra data may be acessed using ExtraScanline property
+ * Fixed * a bug on tIMe chunk
+ French translation included (Thanks to IBE Software)
+ Bugs fixed
+
+ Version 1.432
+ 2002-08-24 - * NEW * A new method, CreateAlpha will transform the
+ current image into partial transparency.
+ Help file updated with a new article on how to handle
+ partial transparency.
+
+ Version 1.431
+ 2002-08-14 - Fixed and tested to work on:
+ C++ Builder 3
+ C++ Builder 5
+ Delphi 3
+ There was an error when setting TransparentColor, fixed
+ New method, RemoveTransparency to remove image
+ BIT TRANSPARENCY
+
+ Version 1.43
+ 2002-08-01 - * NEW * Support for Delphi 3 and C++ Builder 3
+ Implements mostly some things that were missing,
+ a few tweaks and fixes.
+
+ Version 1.428
+ 2002-07-24 - More minor fixes (thanks to Ian Boyd)
+ Bit transparency fixes
+ * NEW * Finally support to bit transparency
+ (palette / rgb / grayscale -> all)
+
+ Version 1.427
+ 2002-07-19 - Lots of bugs and leaks fixed
+ * NEW * method to easy adding text comments, AddtEXt
+ * NEW * property for setting bit transparency,
+ TransparentColor
+
+ Version 1.426
+ 2002-07-18 - Clipboard finally fixed (hope)
+ Changed UseDelphi trigger to UseDelphi
+ * NEW * Support for bit transparency bitmaps
+ when assigning from/to TBitmap objects
+ Altough it does not support drawing transparent
+ parts of bit transparency pngs (only partial)
+ it is closer than ever
+
+ Version 1.425
+ 2002-07-01 - Clipboard methods implemented
+ Lots of bugs fixed
+
+ Version 1.424
+ 2002-05-16 - Scanline and AlphaScanline are now working correctly.
+ New methods for handling the clipboard
+
+ Version 1.423
+ 2002-05-16 - * NEW * Partial transparency for 1, 2, 4 and 8 bits is
+ also supported using the tRNS chunk (for palette and
+ grayscaling).
+ New bug fixes (Peter Haas).
+
+ Version 1.422
+ 2002-05-14 - Fixed some critical leaks, thanks to Peter Haas tips.
+ New translation for German (Peter Haas).
+
+ Version 1.421
+ 2002-05-06 - Now uses new ZLIB version, 1.1.4 with some security
+ fixes.
+ LoadFromResourceID and LoadFromResourceName added and
+ help file updated for that.
+ The resources strings are now located in pnglang.pas.
+ New translation for Brazilian Portuguese.
+ Bugs fixed.
+
+ IMPORTANT: I'm currently looking for bugs on the library. If
+ anyone has found one, please send me an email and
+ I will fix right away. Thanks for all the help and
+ ideias I'm receiving so far.}

+The following changes were made by Lukas Gebauer (geby@volny.cz). In addition, some changes from a previous D5-compatible version were merged, and the supplied sqlite3.dll is updated to version 3.2.2
+
+Notes from Lukas:
+
+- added support for delphi 4+
+
+- datatype constants matches SQlite datatypes contants. (otherwise in some situations you got bad column datatype!)
+
+- removed dependency on strutils
+
+- code is reformated to better look (official borland formationg
+rules)
+
+- added some pragma's after database is open (temp is in memory)
+
+- TSQLiteDatabase.GetTableValue(const SQL: string): int64 for easy call of SQL commands what returning one number only. (like select
+count(*)...)
+
+- TSQLiteDatabase.GetTableString(const SQL: string): String for easy call of SQL commands what returning one string only. (like PRAGMA
+integrity_check)
+
+- TSQLiteDatabase.SetTimeout(Value: integer); you can set timeout for accessing to some table. Good for database sharing!
+
+- TSQLiteDatabase.version: string; returns SQLITE version string
+
+- removed bool fieldtype (it is not natural SQLite3 type)
+
+- fild type detection by Sqite3_columnType knows REAL too.
+
+- integer filedtype is based on Int64
+
+- GetFields can get data from any supported fieldtype
+
+- changed some integers to cardinal for avoid signed and unsigned mismatch
+
+- TSqliteTable.FieldAsInteger(I: cardinal): int64; returns int64
+
+
+3 May 2005 Fixed bug where strupper called on column type before checking for nil
+
+2 May 2005 Add extra check for nil in TSqliteTable.Destroy, thanks to Tim Maddrell
+
+22 Apr 2005 Revise TSqliteTable.Destroy to fix memory leak with dtStr type (thanks to
+Jose Brito)
+
+21 Apr 2005 Quick revision to fix case sensitivity in detecting column type,
+and remove PRAGMA full_column_names = 1 which is deprecated. Warning: may break code. Fix your SQL code so that all column names in a result set are unique.
+
+21 Feb 2005 Sqlite DLL now 3.1.3
+
+19 Feb 2005 Revised for Sqlite 3.1.2
+
+21 Dec 2004 First public release

+What's the point?
+=================
+BASS is an audio library for use in Windows and MacOSX software. Its
+purpose is to provide the most powerful and efficient (yet easy to use),
+sample, stream, MOD music, and recording functions. All in a tiny DLL,
+under 100KB in size.
+
+See the documentation for descriptions of all the BASS functions. You
+should also look at the included example program source-codes for some
+examples of how to use BASS in your own programs.
+
+
+Requirements
+============
+Win32 version
+-------------
+BASS requires DirectX 3 or above for output. BASS does not require that a
+soundcard with DirectSound/DirectSound3D hardware accelerated drivers is
+installed, but it does improve performance if there is one. BASS also takes
+advantage of MMX, which improves the performance of the MOD music playback.
+
+MacOSX version
+--------------
+OSX 10.3 or above is recommended. BASS uses CoreAudio for output, so there
+are no special library/driver requirements. BASS supports both PowerPC and
+Intel Macs.
+
+
+Main Features
+=============
+* Samples
+- supports WAV/AIFF/MP3/MP2/MP1/OGG and custom generated samples
+
+* Sample streams
+- stream any sample data in 8/16/32 bit
+
+* File streams
+- MP3/MP2/MP1/OGG/WAV/AIFF file streaming
+
+* Internet file streaming
+- stream MP3/MP2/MP1/OGG/WAV/AIFF files from the internet (inc. Shout/Icecast)
+
+* User file streaming
+- stream MP3/MP2/MP1/OGG/WAV/AIFF files from anywhere using any delivery method
+
+* Multi-channel streaming
+- support for more than plain stereo, including multi-channel OGG/WAV/AIFF files
+
+* MOD music
+- uses the same engine as XMPlay = best accuracy, speed and quality
+
+* MO3 music
+- MP3/OGG compressed MOD music
+
+* Add-on system
+- support for more formats is available via add-ons (aka plugins)
+
+* Multiple outputs
+- simultaneously use multiple soundcards, and move channels between them
+
+* Recording
+- flexible recording system, with support for multiple devices
+
+* Decode without playback
+- streams and musics can be outputted in any way you want
+
+* Speaker assignment
+- assign streams and musics to specific speakers
+
+* High precision synchronization
+- synchronize events in your software to the music
+
+* DirectX 8 effects
+- chorus/compressor/distortion/echo/flanger/gargle/parameq/reverb
+
+* User defined DSP functions
+- custom effects may be applied to musics and streams
+
+* 32 bit floating-point decoding and processing
+- floating-point stream/music decoding, DSP, FX, and recording
+
+* 3D sound
+- play samples/streams/musics in any 3D position, with EAX support
+
+* Expandable
+- underlying DirectSound object interfaces are accessible
+
+* Small
+- BASS is under 100KB (on Windows), so won't bloat your distribution
+
+
+Using BASS
+==========
+There is no guarantee that all future BASS versions will be compatible
+with all previous versions, so your program should use BASS_GetVersion
+to check the version that is loaded. This also means that you should
+put the BASS module in the same directory as your executable (not just
+somewhere in the path), to avoid the possibility of a wrong version being
+loaded.
+
+If you are updating your software from a previous BASS version, then
+you should check the "History" section (below), to see if any of the
+functions that you are using have been affected by a change.
+
+Win32 version
+-------------
+C/C++, Visual Basic, Delphi and MASM APIs are provided, to use BASS with
+another language you'll first have to convert the header file. Or, as a
+last resort, you could use LoadLibrary and GetProcAddress.
+
+One benefit of the LoadLibrary method is that it allows you to look for
+the correct BASS version, because you can load and unload BASS.DLL at
+any time. This also allows those who'd prefer not to have a separate
+DLL to store it with the program (eg. in a resource), write it to disk,
+load it, use it, free it and delete it.
+
+The downside is that you have to manually import each function that you
+use, with the GetProcAddress function. But it has been made a lot simpler
+to import BASS this way by the use of the BASSDEF #define. Here's a small
+example:
+
+#define BASSDEF(f) (WINAPI *f) // define the functions as pointers
+#include "bass.h"
+...
+HINSTANCE bass=LoadLibrary("BASS.DLL"); // load BASS
+BASS_Init=GetProcAddress(bass,"BASS_Init"); // get BASS_Init
+BASS_Init(-1,44100,0,hWnd,NULL); // call BASS_Init
+
+See the LOADNGET.C file for a more complete example.
+
+To use BASS with Borland C++ Builder, you'll first have to create a
+Borland C++ Builder import library for it. This is done by using the
+IMPLIB tool that comes with Borland C++ Builder. Simply execute this:
+
+ IMPLIB BASSBCB.LIB BASS.DLL
+
+... and then use BASSBCB.LIB in your projects to import BASS.
+
+To use BASS with LCC-Win32, you'll first have to create a compatible
+import library for it. This is done by using the PEDUMP and BUILDLIB
+tools that come with LCC-Win32. Run these 2 commands:
+
+ PEDUMP /EXP BASS.LIB > BASSLCC.EXP
+ BUILDLIB BASSLCC.EXP BASSLCC.LIB
+
+... and then use BASSLCC.LIB in your projects to import BASS.
+
+For the BASS functions that return strings (char*), VB users should use
+the VBStrFromAnsiPtr function to convert the returned pointer into a VB
+string.
+
+MacOSX version
+--------------
+A separate "LIB" file is not required for OSX. Using XCode, you can simply
+add the DYLIB file to the project. Or using a makefile, you can build your
+programs like this, for example:
+
+ gcc yoursource -L. -lbass -o yourprog
+
+The LIBBASS.DYLIB file must be put in the same directory as the executable
+(it can't just be somewhere in the path). See the example makefiles.
+
+LIBBASS.DYLIB is a universal binary, with support for both PowerPC and
+Intel Macs. If you want PowerPC-only or Intel-only versions, the included
+makefile can create them for you, by typing "make ppc" or "make i386". It
+will also process any BASS add-ons placed in the same directory.
+

+
+
+Copyright, disclaimer, and all that other jazz
+==============================================
+The BASS library is free for non-commercial use. If you are a non-
+commercial entity (eg. an individual) and are not charging for your
+product, and the product has no other commercial purpose, then you
+can use BASS in it for free. If you wish to use BASS in commercial
+products, then please also see the next section.
+

+"AS IS", WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY
+AND/OR FITNESS FOR A PARTICULAR PURPOSE. THE AUTHORS SHALL NOT BE HELD

+
+
+BASS in commercial products?
+============================
+BASS is available for use in your commercial products. The licence
+types available are as follows:
+
+SHAREWARE: Allows the usage of BASS in an unlimited number of your
+shareware products, which must sell for no more than 40 Euros each.
+If you're an individual making and selling your own software (and
+its price is within the limit), this is the licence for you.
+
+SINGLE COMMERCIAL: Allows the usage of BASS in a single commercial
+product.
+
+UNLIMITED COMMERCIAL: Allows the usage of BASS in an unlimited number
+of your commercial products. This licence is on a per site basis. So
+if your company has two sites that use BASS, then two licences are
+required.
+
+Please note the products must be end-user products, eg. not components
+used by other products.
+
+These licences only cover your own software. not the publishing of
+other's software. If you publish other's software, its developers (or
+the software itself) will need to be licensed to use BASS.
+
+These licences are on a per-platform basis, with reductions available
+when licensing for both platforms. In all cases there are no royalties
+to pay, and you can use future BASS updates without further cost. One
+licence covers one person or entity and is not transferable.
+
+These licences do not allow reselling/sublicensing of BASS. For example,
+if a product is a development system, the users of said product are not
+licensed to use BASS in their productions - they will need their own
+licences.
+
+If the standard licences do not meet your requirements, or if you have
+any questions, please get in touch (email: bass@un4seen.com).

+
+
+MP3
+===
+MP3 technology is patented, and Thomson license the use of their and
+Fraunhofer's patents. The inclusion of an MP3 decoder (eg. BASS) in a
+commercial product requires an MP3 patent licence. Contact Thomson for
+details:
+
+ www.mp3licensing.com
+
+Alternatively, the "MP3-FREE" BASS version doesn't include its own MP3
+decoder but instead makes use of the operating system's already licensed
+decoder.
+
+NOTE: When using the OS's MP3 decoder, BASS still does the file handling
+ so all the usual features are still supported, including streaming,
+ tag reading, pre-scanning, gapless playback, etc...
+
+
+History
+=======
+These are the major (and not so major) changes at each version stage.
+There are of course bug fixes and other little improvements made along
+the way too! To make upgrading simpler, all functions affected by a
+change to the BASS interface are listed.

+ * resulting decoded frame is stored in \p picture.

+ * @warning The input buffer must be \c FF_INPUT_BUFFER_PADDING_SIZE larger than

+ * @warning The end of the input buffer \p buf should be set to 0 to ensure that
+ * no overreading happens for damaged MPEG streams.
+ *
+ * @note You might have to align the input buffer \p buf and output buffer \p
+ * samples. The alignment requirements depend on the CPU: on some CPUs it isn't
+ * necessary at all, on others it won't work at all if not aligned and on others
+ * it will work but it will have an impact on performance. In practice, the
+ * bitstream should have 4 byte alignment at minimum and all sample data should
+ * be 16 byte aligned unless the CPU doesn't need it (AltiVec and SSE do). If
+ * the linesize is not a multiple of 16 then there's no sense in aligning the

+ * Pixel format. Notes:
+ *
+ * PIX_FMT_RGB32 is handled in an endian-specific manner. A RGBA
+ * color is put together as:
+ * (A << 24) | (R << 16) | (G << 8) | B
+ * This is stored as BGRA on little endian CPU architectures and ARGB on
+ * big endian CPUs.
+ *
+ * When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized
+ * image data is stored in AVFrame.data[0]. The palette is transported in
+ * AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is
+ * formatted the same as in PIX_FMT_RGB32 described above (i.e., it is
+ * also endian-specific). Note also that the individual RGB palette
+ * components stored in AVFrame.data[1] should be in the range 0..255.
+ * This is important as many custom PAL8 video codecs that were designed
+ * to run on the IBM VGA graphics adapter use 6-bit palette components.

+ got no clue wether they are actually used.
+ Don't worry because you are free to use these components
+
+ Timing has improved, however because the messages are handled by the normal
+ windows message loop (of the main window) it is still influenced by actions
+ done on the window (minimize/maximize ..).
+ Use of a second thread with higher priority which only handles the
+ timer message should increase performance. If somebody knows such a component

+unit MidiIn;
+
+{
+ Properties:
+ DeviceID: Windows numeric device ID for the MIDI input device.
+ Between 0 and NumDevs-1.
+ Read-only while device is open, exception when changed while open
+
+ MIDIHandle: The input handle to the MIDI device.
+ 0 when device is not open
+ Read-only, runtime-only
+
+ MessageCount: Number of input messages waiting in input buffer
+
+ Capacity: Number of messages input buffer can hold
+ Defaults to 1024
+ Limited to (64K/event size)
+ Read-only when device is open (exception when changed while open)
+
+ SysexBufferSize: Size in bytes of each sysex buffer
+ Defaults to 10K
+ Minimum 0K (no buffers), Maximum 64K-1
+
+ SysexBufferCount: Number of sysex buffers
+ Defaults to 16
+ Minimum 0 (no buffers), Maximum (avail mem/SysexBufferSize)
+ Check where these buffers are allocated?
+
+ SysexOnly: True to ignore all non-sysex input events. May be changed while
+ device is open. Handy for patch editors where you have lots of short MIDI
+ events on the wire which you are always going to ignore anyway.
+
+ DriverVersion: Version number of MIDI device driver. High-order byte is
+ major version, low-order byte is minor version.
+
+ ProductName: Name of product (e.g. 'MPU 401 In')
+
+ MID and PID: Manufacturer ID and Product ID, see
+ "Manufacturer and Product IDs" in MMSYSTEM.HLP for list of possible values.
+
+ Methods:
+ GetMidiEvent: Read Midi event at the head of the FIFO input buffer.
+ Returns a TMyMidiEvent object containing MIDI message data, timestamp,
+ and sysex data if applicable.
+ This method automatically removes the event from the input buffer.
+ It makes a copy of the received sysex buffer and puts the buffer back
+ on the input device.
+ The TMyMidiEvent object must be freed by calling MyMidiEvent.Free.
+
+ Open: Opens device. Note no input will appear until you call the Start
+ method.
+
+ Close: Closes device. Any pending system exclusive output will be cancelled.
+
+ Start: Starts receiving MIDI input.
+
+ Stop: Stops receiving MIDI input.
+
+ Events:
+ OnMidiInput: Called when MIDI input data arrives. Use the GetMidiEvent to
+ get the MIDI input data.
+
+ OnOverflow: Called if the MIDI input buffer overflows. The caller must
+ clear the buffer before any more MIDI input can be received.
+
+ Notes:
+ Buffering: Uses a circular buffer, separate pointers for next location
+ to fill and next location to empty because a MIDI input interrupt may
+ be adding data to the buffer while the buffer is being read. Buffer
+ pointers wrap around from end to start of buffer automatically. If
+ buffer overflows then the OnBufferOverflow event is triggered and no
+ further input will be received until the buffer is emptied by calls
+ to GetMidiEvent.
+
+ Sysex buffers: There are (SysexBufferCount) buffers on the input device.
+ When sysex events arrive these buffers are removed from the input device and
+ added to the circular buffer by the interrupt handler in the DLL. When the sysex events
+ are removed from the circular buffer by the GetMidiEvent method the buffers are
+ put back on the input. If all the buffers are used up there will be no
+ more sysex input until at least one sysex event is removed from the input buffer.
+ In other words if you're expecting lots of sysex input you need to set the
+ SysexBufferCount property high enough so that you won't run out of
+ input buffers before you get a chance to read them with GetMidiEvent.
+
+ If the synth sends a block of sysex that's longer than SysexBufferSize it
+ will be received as separate events.
+ TODO: Component derived from this one that handles >64K sysex blocks cleanly
+ and can stream them to disk.
+
+ Midi Time Code (MTC) and Active Sensing: The DLL is currently hardcoded
+ to filter these short events out, so that we don't spend all our time
+ processing them.
+ TODO: implement a filter property to select the events that will be filtered
+ out.

+
+unit MidiOut;
+
+{
+ MIDI Output component.
+
+ Properties:
+ DeviceID: Windows numeric device ID for the MIDI output device.
+ Between 0 and (midioutGetNumDevs-1), or MIDI_MAPPER (-1).
+ Special value MIDI_MAPPER specifies output to the Windows MIDI mapper
+ Read-only while device is open, exception if changed while open
+
+ MIDIHandle: The output handle to the MIDI device.
+ 0 when device is not open
+ Read-only, runtime-only
+
+ ProductName: Name of the output device product that corresponds to the
+ DeviceID property (e.g. 'MPU 401 out').
+ You can write to this while the device is closed to select a particular
+ output device by name (the DeviceID property will change to match).
+ Exception if this property is changed while the device is open.
+
+ Numdevs: Number of MIDI output devices installed on the system. This
+ is the value returned by midiOutGetNumDevs. It's included for
+ completeness.
+
+ Technology: Type of technology used by the MIDI device. You can set this
+ property to one of the values listed for OutportTech (below) and the component
+ will find an appropriate MIDI device. For example:
+ MidiOutput.Technology := opt_FMSynth;
+ will set MidiInput.DeviceID to the MIDI device ID of the FM synth, if one
+ is installed. If no such device is available an exception is raised,
+ see MidiOutput.SetTechnology.
+
+ See the MIDIOUTCAPS entry in MMSYSTEM.HLP for descriptions of the
+ following properties:
+ DriverVersion
+ Voices
+ Notes
+ ChannelMask
+ Support
+
+ Error: The error code for the last MMSYSTEM error. See the MMSYSERR_
+ entries in MMSYSTEM.INT for possible values.
+
+ Methods:
+ Open: Open MIDI device specified by DeviceID property for output
+
+ Close: Close device
+
+ PutMidiEvent(Event:TMyMidiEvent): Output a note or sysex message to the
+ device. This method takes a TMyMidiEvent object and transmits it.
+ Notes:
+ 1. If the object contains a sysex event the OnMidiOutput event will
+ be triggered when the sysex transmission is complete.
+ 2. You can queue up multiple blocks of system exclusive data for
+ transmission by chucking them at this method; they will be
+ transmitted as quickly as the device can manage.
+ 3. This method will not free the TMyMidiEvent object, the caller
+ must do that. Any sysex data in the TMyMidiEvent is copied before
+ transmission so you can free the TMyMidiEvent immediately after
+ calling PutMidiEvent, even if output has not yet finished.
+
+ PutShort(MidiMessage: Byte; Data1: Byte; Data2: Byte): Output a short
+ MIDI message. Handy when you can't be bothered to build a TMyMidiEvent.
+ If the message you're sending doesn't use Data1 or Data2, set them to 0.
+
+ PutLong(TheSysex: Pointer; msgLength: Word): Output sysex data.
+ SysexPointer: Pointer to sysex data to send
+ msgLength: Length of sysex data.
+ This is handy when you don't have a TMyMidiEvent.
+
+ SetVolume(Left: Word, Right: Word): Set the volume of the
+ left and right channels on the output device (only on internal devices?).
+ 0xFFFF is maximum volume. If the device doesn't support separate
+ left/right volume control, the value of the Left parameter will be used.
+ Check the Support property to see whether the device supports volume
+ control. See also other notes on volume control under midiOutSetVolume()
+ in MMSYSTEM.HLP.
+
+ Events:
+ OnMidiOutput: Procedure called when output of a system exclusive block
+ is completed.
+
+ Notes:
+ I haven't implemented any methods for midiOutCachePatches and
+ midiOutCacheDrumpatches, mainly 'cause I don't have any way of testing
+ them. Does anyone really use these?

+Midi components
+ TMidiFile, TMidiScope
+ TMidiIn and TMidiOut of david Churcher are included because they are used in
+ the demo application
+
+Freeware.
+
+100% source code, demo application.
+
+Included Components/Classes
+
+TMidiFile, read a midifile and have the contents available in memory
+ list of Tracks, track is list of events
+
+
+TMidiScope, show all activity on a midi device
+
+TMidiIn and TMidiOut of David Churcher are included because they are used
+in the demo application
+
+Midiplayer is a demo application which plays a midifile on a midi output
+ it is build fairly simple with the included components. The timer is used
+ to time the midievents. The timing is therefor as good as the windows timer.
+
+
+ The header of midifile,midiscope contains help information on the properties/functions
+ The example Midiplayer gives a good idea how to use the components
+
+Installation
+ open midiComp.dpk with file/open
+ compile and install the package
+ make sure that the directory where the files are located is in the library path
+ (tools/environment options/library)
+
+to run the demo
+ open project1.dpr in the demo directory and press run.
+
+
+
+history
+1.0 18-1-1999 first release
+
+1.1 5-3-1999 update
+ added some functions for display purposes
+ improved demo to include event viewer
+ bpm can be changed
+
+1.2 24-2-2000 update
+ added some functions to see the length of a song and ready function to know when playback is ready
+
+for comments/bugs in these components:

+
+I'm busy building a software music synthesizer, which will be available in source
+to the public. If you are interrested in helping me with certain soundmodules
+(effects, filters, sound generators) just sent me an email.
