Eurorack 2 channel quantizer for analogue sequencers

0x03 2ch Quantizer

This thing is a two channel CV quantizer for Eurorack, intended to make sure some oscillators played by an analog sequencer are actually playing in tune :)

• two CV input channels, each input 0-5V is mapped to output 0-4.096V, four octaves @ 1V/oct.
• transpose knob per channel, +/- 1 octave in semitone steps
• The green LEDs will be brighter when transpose is set to -12/0/+12 half notes
• Red LED lights up if any channel tries to go off limits

Prototype build for Eurorack (complete with panel) was OK :)
