   (0 reviews)

The 6 voice analog and organ synthesizer from Crumar has 2 DCO oscillator that feature saw, square, and, a mix of the two as well as a unison mode and, additionally a unique mode called Alternate Saw/Sq mode which alternates the voices between square and sawtooth waveforms.

The instrument offers 6 VCF's and 6 VCA per voice and the LFO has an adjustable slope with delay controls, A different feature found on the Stratus is Octave Modulation mode where the LFO applies square wave pitch modulation over an entire octave. The Oscillator Glide is Crumar's Portamento mode with it's own features.

The keyboard is 49 key keyboard. No aftertouch or velocity but a joystick controller for pitch and modulation. No memory for saving user data but it does feature separate outputs for the organ and synth sections.

The instrument has no CV in/out nor MIDI in/out but there was breath controller unit called the Steiner Master's Touch wind controller that let the player use it for pitch bending and modulation.
