E.P.S.S. and Cubase on Atari STe

E.P.S.S. (Enhanced Polyphonic Sample Synthesizer) working as a plugin to Cubase 3 on Atari STe.

E.P.S.S. is a bit like VST, but arrived already in 1990 in the Atari demo scene. It plays eight channels at 25 kHz mixing (and on the Mega STe, 16 channels). The sound driver and patch file is controlled with E.P.S.S. Accessory running in parallel with Cubase. Cubase have an MROS driver to use for talking with the E.P.S.S. Accessory.

All this in 1990! Years ahead of anything like it.

You could also use the Cubase score in your own productions using the E.P.S.S. sound driver and MIDI file player. It doesn't use more CPU than your normal Protracker MOD-file player, and runs completely off VBL for minimum hassle.
