Install option boards to add PCM sounds or a DSP tone generator
In addition to the internal PCM sounds, the Karma Music Workstation can accommodate the same optional EXB-PCM series PCM Expansion Boards available for the TRITON. Each board adds 16 Mbytes of PCM data plus programs and combinations that use this data, further broadening your sound palette. However it does not include new GE's or GE assignments.

EXB-MOSS DSP SYNTHESIZER BOARD
KARMA can be expanded by the installation of the ultimate DSP tone generator --- the 13 oscillator 6-voice MOSS (Multi-Oscillator Synthesis System) tone generator featured on the Z1. This 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.

MOSS SPECIFICATIONS
Sound Source: 6 voices, 2 oscillators (max.) + sub oscillator + noise generator
Oscillator Types: 13 (Standard, Ring Modulation, Cross Modulation, Oscillator
Sync, VPM (Variable Phase Modulation), Comb filter oscillator, Resonance oscillator, Organ model, Electric piano model, Brass model, Reed model, Plucked string model, Bowed string model)
Programs: 128

16 track sequencer + KARMA functionality = enhanced music production
The Karma Music Workstation contains a 16-track sequencer with a capacity of up to 200,000 notes and 200 songs (up to 999 measures for each song). Phrases generated by the KARMA function can be recorded directly, and you can add manually-played and step-recorded phrases to create a song quickly and easily.

The RPPR (Realtime Pattern Play/Recording) function lets you play back a phrase by pressing a single key, and 150 drum and percussion patterns are provided. Many other convenient functions help you produce songs efficiently, such as Template songs, which allow you to call up a pre-arranged group of instruments and effects, and a Track Play Loop function that lets you specify looped measures independently for each track. A Cue List function lets you assemble your final song from up to 99 different sequences for easy arranging.

Songs you create can be saved in SMF (Standard MIDI File) format or in a KORG TRITON compatible format so that data can be exchanged with other devices. (Note - The TRITON arpeggiator function can not be reproduced on the KARMA Music Workstation.)

The Song Play mode allows you to play back SMF files directly from floppy disk. You can perform on the keyboard along with the playback, or use the KARMA function in sync with the playback tempo.

Four channel audio output
In addition to the L/MONO and R main stereo audio outputs, you can use two independent audio outputs for a total of four channels of audio output. Oscillators, drums, timbres/tracks, and the signals from the insert effects can be freely routed to any output.
