Turbo Sound FM
It uses two YAMAHA YM2203 chips. These are equivalents of the AY-3-8910 chips used in ZX Spectrum and Sizif-512. Each can generate 3 channels, providing 6 FM synthesizer channels. The device is also compatible with YM2612 (OPN2), meaning it can play Sega MegaDrive/Genesis music, with some limitations.
MIDI
It allows playing *.mid music files using synthesized musical instruments stored in the chip. It uses the SAM2695 processor. Features 256 musical instrument samples, 64-channel polyphony, effects (reverb, chorus), stereo.
SAA1099
This is a sound card built around the 6-channel Phillips SAA1099 chip, used in early SoundBlasters and Sam Coupe.
General Sound
This sound card is designed for playing 4-channel MOD modules (from Amiga and PC computers) and individual samples (both Amiga-signed and unsigned PC samples). It’s practically a second computer with its own Z80 12MHz processor and 512kB RAM.
