The all-important sound generator is a high-performance synthesizer offering 64-note polyphony. A rich array of parameters, including sharp filters and ADSR envelopes can be modified using the knobs on the panel to create your own sounds. The sound generator can also be used as a multitimbral sound module, providing up to eight parts.
