Here's a quick explanation of the files included in this zip file: README.TXT : This file PM.TXT : A quick explanation of the PM.EXE midi player PM.EXE : PM - a command line midi file player MAKETMB.EXE : this generates TMB files for use by PM. Read GMTIMBRE.INI GMTIMBRE.TMB : A timbre file generated by MAKETMB GMTIMBRE.INI : An example timbre script for MAKETMB. Generates GMTIMBRE.TMB PERCUS.IBK : General MIDI percussion instruments. Used by GMTIMBRE.INI GENMIDI.IBK : General MIDI percussion instruments. Used by GMTIMBRE.INI TIMBRES.ZIP : A couple sets of instrument banks that can be used as source material for fm instruments. MAKETMB is a simple utility to allow developers to develop and use their own FM instrument banks with the Apogee Sound System. It can generate either a data file or source code (ask me if you'd prefer to use this feature) containing the instruments and usable by the sound system. The benefit of having the instruments in a data file is that multiple files could be made, each with instruments specific to a particular song or set of songs. It also allows you to make quick changes to the instruments and hear them in a song (using PM) very quickly, without having to recompile the code (very useful for musicians). I know I'm terrible at writing documentation, so if these files are a little vague, give me a call and I'll walk you through it. Jim Dosé‚ (214)-271-1365 Ext. 221
