There are four slider pots to the left of the keyboard to control volume, touch sensitivity, brilliance (VCF Cutoff), and portamento speed during live performance. A 3-position octave switch allows "normal" or plus or minus one octave transposition of the 3-octave keyboard to extend the range of the instrument to five playable octaves; the total range of instrument across all presets covers 8 octaves. There is also a rotary pot which serves double duty to control both the rate of Vibrato or Tremolo (dependent upon preset) and Repeat, which causes the LFO to retrigger the envelopes of any selected voice upon key depression.
