YMT Play

Let's bleep and bloop the night away!

What better way to end a great Christmas than listening to cool chiptunes using YMT Play by Peter Jørgensen (aka Bionic Nerd). This program features YM music data streaming, like the typical ST-sound playback using a sound range from 50hz -> 300hz and with very little CPU usage. The quality is outstanding and I'm sure you will find its potential interesting and an exciting concept? Go and download YMT from Demozoo.

What is YMT?
"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.
To my knowledge, there has 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, then it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc.

The disadvantaged is that it uses a lot of memory, and 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."
