This module provides high precision CV outputs in 1V (octaves) and 83,3mV (semitones) steps. The 1V output goes from -5 to +5V. The 83,3mV steps goes from -5 to plus 5 steps (semitones). This module is thought for all who are missing octave switches in some modules. Especially in VCO. With this module you can switch octaves and semitones as well.
Specs and features
- High precision output from -5V to +5V in 1V steps (octaves)
- High precision output in 83,3mV steps, +/- 5 steps (semitones)
- Runs on +/-15V and +/-12V
- Power consumption around 30mA each rail
