Alfa Delta Dionisi Digital VCO

Digital module with analog ins and outs, analog look and feel.
Analog controlled digital oscillator x 6. One output per oscillator.
Two mix outputs. Six assignable inputs per mixer, can be VCO outputs or CV inputs.
Frequency follows first oscillator with (quantized) detune and Fine Hz or independent frequency control or frequency ratio per oscillator.
1V/oct, 12 octaves range, perfect tracking.
4 frequency ranges per oscillator from 0.0033 Hz (that is 303 seconds) to 20 kHz.
Classic waveforms (sine, triangle, saw, ramp, square pulse), selectable per oscillator.
Voltage Controlled FM, Linear FM (thru-zero), AM (4-quadrant), Morph, per oscillator.
Phase modulation thru-zero, initial phase adjustable from -360 to + 360 degrees in 1 degree steps.
AM, PM and FM depth control from CV inputs or VCO outputs.
All modulations from zero to full depth from DC to 20 kHz.
8 freely assignable CV modulation inputs with initial and depth control (NO attenuverters !) and peak detect indicator on display.
6 freely assignable gate inputs for syncing (positive edge, negative edge, both edges. reset phase).
Cross modulation of each parameter of each oscillator (6-operator FM or PM).
Quantizer with different scales (Equal, Just, Pythagoras aug4, Pythagoras dim5, Mean tone, Harmonic, Werckmeister, Arabic).
16 bit resolution on all inputs and outputs, sample rate is 100 kHz, anti-aliased waveforms.
Easy parameter navigation : 4-line 21-character graphic OLED display, 3 encoders, 6 buttons, no menus.
Useful presets like FM algorithms, chords, additive synthesis and more.
MIDI input for firmware and preset updates and MIDI notes (note number (ST) 60 is middle C (C4)), velocity, after touch, continuous controllers and preset selection (bank and program change).
MIDI controller "learn" mode immediately assigns a MIDI controller as a modulation source.
Extensive manual, which is needed for a complex module like this.
Handy Patch sheets in Pages and Word format.
