The Studio Electronics ModStar Grainy Clamp-It is a granular additive oscillator module. Grainy Clamp It utilizes two stages of synthesis to create its unusual timbres and tones. 

The first stage provides additive mixing between the harmonics of the 16 onboard waveforms. The second stage provides granular or phase modulated mixing of the first stage, providing distortion, sync detune and even wave sequencing effects.

Grainy clamp it provides a rich and complex synthesis architecture, based around additive mixing and granular processing. The end results are obscure, dissident but with organ style characteristics.

The main features of the Studio Electronics Grainy Clamp-It Additive Synthesis Module include

Four stage additive synthesis module

16 onboard waveforms with granular and phase processing

Waveform sequencing, detune and sync

19HP wide

Requires 50mA
