SD-1 Music Production Synthesizer

   0 reviews  -  3413 views

    The structure of the SD-1 is the same as the VFX/VFXSD with more transwaves and polyphony. The added 17 transwaves gives the instruments their wavetable synthesis sound.

    The structure of the previous two is still intact with a stable new OS that is backwards compatible and more programs/multisets available for use and storage.

    The SD-1 still offers 3 envelopes per voice, 4 LFO's, and up to 24 programs in Multimode.
