"GRAINY CLAMP-IT (Cookin' in the Kitchen with Grainy!)

GRAINY CLAMP-IT is a granular and phase modulated additive oscillator—brand new heavy territory for Studio Electronics... we know; wait till you hear the stunning contrast it creates when paired with our discrete Class-A OSCILLATION module, and the inorganic to downright 1970's combo organy / CS-80-ish tones it can generate. Pure voltage-controlled candy. Be sure to wash off the sticky...

Best to break Granny Clampett's namesake down in stages, and time travel a bit.

First Stage - Additive mixing of 4 harmonics using one of 16 waveforms, and one of 16 combinations of harmonics.

Second Stage - Granular or phase modulated mixing of the signal from the first stage, with a sync option.

Back to the First Stage - Additive section with selection of 16 different combinations of harmonics. The harmonics can be based on a sinewave or on one of 15 other waveforms. There's a separate control for mixing the selected harmonics.

Back to the Second Stage - The second processing stage allows granular processing or phase distortion. Granular processing gives you control over grain length and grain position, and can produce sync, detune, and wave sequencing effects. Phase distortion allows the signal from stage one to "look up" non-linearly, and can produce thick detune sounds and wildly varying pitch/timbre effects.

Both settings have a choice of long buffer length (for wave sequencing effects) or short buffer length (for smoother detuned effects).

See it's just additive mixing of several combinations of harmonics using a choice of 16 waveforms, followed by granular or phase modulated processing for detuned and wave sequencing effects, with a sync option for further pitch variations. Capiche? A Ver. 1 signal flow chart should help.

Potentiometer Potential
Ten attenuation pots: WAVE TYPE, OT TYPE, DETUNE, OT MIX CV, PITCH, OT MIX, L/P CV, S/A CV, LEN/PITCH, SPACE/AMT.

Patch it Up
Eight patch points: GRAIN/PD, FIX, RANGE, 1V/OCT, L/P CV, OMX CV, S/A CV, OUTPUT.

Pots and Switches- Arranged in order of signal flow
WAVE TYPE – Selects one of 16 source waveforms.
OT TYPE – Combines 4 copies of the Wave Type – selects one of 16 variations of four overtones.
OT MIX – Controls the mix of the four overtones, from lowest pitched to highest pitched dominance.
DETUNE – Combines the resulting mix with a copy of itself and detunes it up to one octave.
GRAIN/PD – Selects the next processing stage: Up: Granular, or Down: Phase Distortion.
GRAIN
LEN/PITCH – Sets the grain length, for pitch and sync effects.
SPACE/AMT – Sets the spacing between grains, for detune/wave-sequence effects.
FIX – Up: Len/Pitch controls pitch; Down: Len/Pitch controls sync.
RANGE – Up: Grain sample window is long, for wave sequencing (set Space Amt to 0 ); Down: Grain sample window is short, for detune effects.
PD
LEN/PITCH – Controls the pitch of the processed sound.
SPACE/AMT – Controls the amount of phase distortion.
FIX – Up: the pitch control of Len/Pitch is continuous; Down: Len/Pitch selects a range of fixed pitches.
RANGE – Up: PD sample window is long, for wave sequencing; Down: PD sample window is short, for detune effects.

Patch Points
1V/OCT – One volt per octave control voltage input.
L/P CV – Length/Pitch control voltage.
OMX CV – Oscillator Mix control voltage.
S/A CV– Space Amount control voltage.
OUTPUT– Audio Output.
