But I'm not talking about using the CPU. Reread what I wrote.
Oh right... Well I knew about AGA being able to do double-speed DMA.

Is it possible to port glx2.12 (galaxy music player) to support the tandy-dac and the tandy/cga ?

Oh, definitely. I'm impressed that GLX manages stereo MOD playback at 32kHz using the PAS16 in my own wimpy 1000 RL system. Quite respectable....glx seems to be more usable.
Mod Master XT Support the tandy DAC in DMA Ok, Mod Master XT did not exist when you wrote this comment.Using a parallel port DAC on a PSSJ-bearing Tandy would be somewhat redundant. The Tandy DAC supports the "direct write" playback method that Scali mentioned (this, in addition to a DMA-transfer mode). By configuring the Tandy DAC to operate in direct-write mode, and patching the parallel port list to refer to the DAC address, you essentially have an internal Covox Speech Thing. Jeffrey Hayes', "SETDAC" utility was written to do exactly this. With it, and concerning GLX playback on the Tandy 1000 RL (using the LPT2 entry as an example):
setdac.com /p2
glx.exe /oc2 /m11 modfile.mod
Et, voilà - GLX sound, but no graphics from the Tandy video chipset outside of the MDA mode, as vwestlife mentioned.
Jeffrey Hayes also created a Tandy-DAC-specific MOD/S3M player though, if that's of any interest as an alternative.
