Quad Performance Quantizer with Fine-Tuning

Commissioned by Chris Meyer (Alias Zone / Learning Modular) - this is a 4-channel Pitch CV fine-tuning tool with quantization and performance-oriented transpose controls. Each channel can be clocked for latching of Transpose or full S&H of the input. As of v1.10, channels can be chained together, mixing the output of any channel with the input of the next - a precision adder for building harmonic intervals. There are 4 preset banks to store and recall configurations.

The Fine Tune controls at the bottom of the main view apply voltage Scaling and Bias Offset to the output stage, per channel. Scaling is in increments of ±0.01% and Bias is effectively ±1/128th of a semitone.

Accurate performance will depend on the calibration of your o_C module itself.

UI Controls

Button / Encoder	Action
UP / DOWN (or A / B) buttons	switch channels
Quick-press Left Encoder	switch between Transpose and Fine-Tune controls
Quick-press Right Encoder	toggle Scale & Root Note selection
Long-press Left Encoder with cursor on Transpose	cycle modes per channel: Clocked Transpose, Clocked S&H, Chain-To-Next
(new in v1.6.777) Long-press Left Encoder with cursor on Fine-Tune controls	Auto-tuner closed loop DAC calibration routine, ported from References
Long-press DOWN (or B) button	Preset switching menu - turn or press Left Encoder to toggle Save/Load - use Right Encoder to select - UP or DOWN to cancel
Dual-press UP+DOWN (or A+B)	Clock Setup (shared with Hemispheres)

As of v1.6.6, storing a preset will automatically save App Data to EEPROM in the background.
