New! Software Synthesizer in development!
GMPlay 1.3a update archive now really available!
CAMD library has severe bug in SysEx Queue!

Last update: 21. April 1998

A new project was recently started. It is a software synthesizer based on GMPlay 1.3's synthesizer engine. A software synthesizer reacts to MIDI data and gives a realtime audio response. In the PC domain especially Yamaha software synthesizers have etablished a good marked position. On fast processors, these programs reach a sound quality that is equivalent to Yamaha hardware soundcards.

Current work-in-progress archives can be downloaded from Aminet. It is called CAMD_Toolkit.lha because it is based on Commodore's camd.library (camd.lha). The archive contains a SMF (MID) file player and two monitoring programs. The only commercial software using CAMD library is currently Deluxe Music II by Electronic Arts. However it would be an easy job to write CAMD a compatible MIDI-Out tool for Bars & Pipes.

Unfortunately a very problematic bug is delaying my work. It is impossible to retrieve more than two SysEx messages that have been sent into the SysEx queue of a MIDI node. The bug has been repored to Amiga Inc., but I doubt it will be fixed by them. I will try to trace into the library and release a patch for the library. SysEx messages are important for switching MIDI modes and effects.

The bad news: I am upgrading to an AMD K6/233 PC with 128MB of SDRAM and probably a combinaiton of Linux and Windows 98. The good news: I want to run UAE on my PC and help developing UAE (direct SCSI support would be fine).

By the way: The animated logo on top was rendered with Caligari24 by the way. You can have a look at the large version (20 kb). These pages are not yet complete. You may look forward to all the good things to come.


What is GMPlay?

GMPlay is a player program for MIDI Files for the Commodore Amiga. These files usually carry the extension ".MID" and they are commonly used in the PC sector. GMPlay is currently the only public program to listen to MIDI files with the Amiga computer (without additional hardware).

MIDI files are very short in contrast to the so called sound modules (short: mods or mod-files), but nevertheless they may sound very excellent. The MIDI standard is also used for professional music (with accordingly expensive equipment).

Please understand that GMPlay cannot create impressive sound miracles. We had to find a compromise between available CPU power and sound quality. GMPlay however is constantly developed and we are striving for a higher sound quality with every new release.


System requirements

An Amiga with MC68020 CPU or better. Kickstart 2.0 or better is required.


Technical Data

Note: Graphical user interfaces are available seperately (Aminet). Meanwhile some of them have been adapted to the lates GMPlay release 1.3. It is easy to start GMPlay from web browsers or directory utilities (DOpus).

Remark: Until now the program has been published as freeware, that means we do not claim any fee for its use. However we thankfully accept any voluntary gifts and donations. Future versions will probably released as crippled shareware.


Where can I find MIDI-Files?

There are thousands of FTP and HTTP (Web-) servers in the internet with tons of MIDI-files. A lot of CD-Roms have been published in the PC sector with a vast amount of MIDI files. Unfortunately most of the file names follow the MS-DOS 8+3 naming scheme. Therefore it is very difficult to find or keep an order.

Here I give you an excerpt from my IBrowse hotlist. These links can serve as starting points for finding and exploring the big MIDI archives.

There are a lot of excellent MIDI files, but as well a lot of junk. To sort the trash out is a time consuming job. It is best to look for a well sorted MIDI archive that offers a high quality standard.

Legal hits: MIDI files are digitally encoded musical works. Basically the same rules apply for MIDI file as for any other form of printed or recorded music, especially if they contain a protected and copyrighted compositions (e.g. current hits from the charts). Most of the MIDI archives contain material, that they are not allowed to spread, for example because some of the material is part of a commercial collection of MIDI files. It may cause you legal trouble to blindly spread and copy any MIDI-files without checking for their origin and copyrights.


When will we see a new GMPlay version?

Good question. Next question, please.

Meanwhile help testing my new Software Synthesizer. Any changes and improvements that are made to the Software Synthesizer will be available for GMPlay immediately. That's because the two programs use the same sound engine!

The first changes will directly try to improve sound quality. I will start with the implementation of the ADSR envelopes.

I am sorry for having delayed the date of release for so long. My studies do currently require a lot of attention. And by the way, I can use a lot of things for GMPlay that I learn at university. ;-)

The next release 1.4 will definitely be functionally limited shareware demo! You will probably only notice the demo limitation if you use the program a lot.
