YMT-Player is a player that allow you to play Project-Ymer YMT files (Windows) on the Atari ST. The program is made by Peter Jørgensen aka. fedepede.

What is Project-Ymer YMT files ?

YMT files are like the YM/AY files. Music files where you sampled data from the sound chip register (YM2149/AY8910) in a certain interval, instead of having a dedicate player. Up to now (to my knowledge), there have only been YM/AY player that could play tune/score files, that was sampled at 50HZ, but the YMT player can play files up to 300hz (there are some 50hz+ tunes/scores include in the examples)

The advantaged of AY/YM/YMT format, is that to replay these tunes/scores cost very little CPU power, so if you need a lot power for a eg. a 3D demo,  when it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc, and the disadvantaged is that it use a lot of memory, and also that it is nearly impossible to make a routine that can capture and use the SID sound and Samples etc. It is also why those files need to be hand made, that is the reason why YMT-Player only support pure YM2149 sound.

The rar archive both contain a Floppy and a HD version.
