Ripsaw

Acid Rain Technology

A stereo super oscillator with 4 independent voices, each comprising 7 detunable waveforms, offering individual pitch control per voice and waveform morphing from sawtooth to square.1097

Capabilities 2

Oscillatoroscillator
Ripsaw implements a 4-voice paraphonic super-oscillator, each voice containing 7 detunable waveforms morphable between sawtooth and square.1097
Super Sawsuper-saw
Each voice contains 7 oscillators detuned using curves from a classic 1990s supersaw synthesizer, spread across the stereo field.1097

Jacks 9 (7 in / 2 out)

Inputs (7)
Shape CVcv-5V to 5VOffsets the Shape knob position; expects voltages between -5V and +5V.1097
Shift CVcv-5V to 5V1097
Spread CVcv-5V to 5VOffsets the Spread knob position; expects voltages between -5V and +5V.1097
v/o1cv-5V to 7VPitch CV input for voice 1; controls the pitch of its 7 detunable waveforms. Voice 1 is always active even with no cable patched.1097
v/o2cv-5V to 7VPitch CV input for voice 2; plugging in a cable activates voice 2.1097
v/o3cv-5V to 7VPitch CV input for voice 3; plugging in a cable activates voice 3.1097
v/o4cv-5V to 7VPitch CV input for voice 4; plugging in a cable activates voice 4.1097
Outputs (2)
Out LaudioLeft stereo audio output; all voices' waveforms are spread across the stereo field. Can be used alone for mono operation.1097
Out RaudioRight stereo audio output; all voices' waveforms are spread across the stereo field.1097

Parameters 5

NameTypeRangeBehavior
EncoderknobTurning changes the root pitch of all 4 voices in semitone steps; the note is shown on the LED display.1097
Encoder Fine Tunemenu_setting0cent – 99centAccessible via encoder short press; sets the root pitch fine tuning offset in cents from 0 to 99, useful for matching other gear that deviates from precise 1V/oct.1097
Shape KnobknobMorphs the waveform of all oscillators between sawtooth and square waves.1097
Shift KnobknobRaises the pitch of a hard-sync oscillator paired to each of the 28 audible oscillators, introducing additional harmonics beyond the classic supersaw/supersquare sound.1097
Spread KnobknobDetunes all 7 oscillators of each voice away from their current pitch using offset curves derived from a classic 1990s supersaw synthesizer.1097
