SNDH won't help me too
I need it as a YM file in order to convert & compact it with my own software so that i will be able to replay it on an old Z80 based computer.
I know how to replay the SNDH and read YM registers with some lines of GFA but how to detect Digidrums ? at least, just a reliable method to detect a digidrum-start on one of the voice, no matter witch sample it is (snare,drums,etc... i could find this later).
I'm used to switch off the tone with Reg7 (mixer) on the voice where i play a sample. I could use it for the detection but i don't know if it work the same with chip player on the Atari and if it will be reliable enought...
Maybe i could do some PEEK somewhere in the replay rout' to find a byte that change if a sample is running or some stuffs like this, but i really don't know much in 68K Asm (i'm lost, too much & too big registers for me
btw, simple curiosity, does the digidrums support is managed from the tracker used to compose the music or is it a trick added to the replay rout' (for exemple when period register of a voice is 0x000 then the sample number to play is stored in the volume register) ?
