EXB-MOSS DSP SYNTHESIZER BOARD

via this auction

"The TRITON series, TRITON Rack and Karma Music Workstation can be expanded by the installation of the ultimate DSP tone generator --- the 6-voice MOSS (Multi-Oscillator Synthesis System) tone generator featured on the Z1. Equipped with 13 oscillator algorithms, the MOSS expansion board lets you use all synthesis methods --- PCM, analog, VPM (variable phase modulation), and physical modeling --- on a single instrument. When the MOSS tone generator is installed, 128 MOSS programs are added. You can create combination programs that use multiple MOSS timbres together with HI sounds.

MOSS (MULTI OSCILLATOR SYNTHESIS SYSTEM)

The MOSS sound generator consists of Voice, EG and LFO sections. The voice section contains two powerful oscillator blocks OSC1/OSC2 which let you combine up to two of thirteen types of oscillator algorithm (resonance, organ model, electric piano model, standard, ring modulation, VPM, brass model, reed model and more), a sub oscillator, and a noise generator. The voice section also contains a filter block featuring two multi-mode filters that cover the range from analog synth sounds to complex sounds such as the body resonance of violin or guitar, or even human voice. To this are added five EG units and four LFO units, providing a rich variety of tonal and pitch changes for each voice.
