Polymorphic, quantizing 4x CV processor/generator, built around DAC8565 and teensy 3.x (cortex M4)

specs:

• 4x CV outputs (16 bit), 'in-the-loop' compensated, for proper DC accuracy. output range: -3v / +6v
• 4x CV inputs (-3.5v / +6.5v, 12bit, 100k input impedance).
• 4x digital inputs (100k input impedance, threshold ~ 2.5V)
• trigger-to-quantized-output latency < 100us
• 128x64 1.3" OLED display
• reprogrammable / open-source
• 85mA (@120MHz)

firmware ('apps"):

• CopierMaschine: quantising, four stage analogue shift register (ASR), with user-editable scales.
• Harrington 1200: basic neo-Riemannian Ton-Netz transformations
• Automatonnetz: combines Ton-Netz transforms with a "vector" sequencer
• Quantermain: quad quantiser with user-editable scales + built-in "Turing Machines"
• Quadraturia: wavetable quadrature LFO
• Low-rents: dual Lorenz and Rössler generators (strange attractors)
• Piqued: quad voltage-controlled envelope generators
• Dialectic Ping Pong: quad bouncing balls
• Viznutcracker, sweet!: quad "byte beat" equation generator
• References: a simple utility app that outputs specific reference voltages
• easy-to-use 10-point calibration menu (10 points per channel).
