Dionisi

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.
• PM and FM index (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.
