Midimuso MDCO-3 Manual

Midimuso MDCO-3
Overview:
The Midimuso MDCO-3 is a MIDI-controlled, 2 voice oscillator IC with
Volts / Hz high-resolution control voltage outputs.
Two independent square-wave oscillators per chip.
Two separate trigger outputs for envelope generators / gates.
(5V for "note on" or 0V for "note off")
Chainable: More MDCO-3s can be linked to produce more polyphony
(up to 12 mono voices, unlimited Poly / Unison voices *)
Volts / Hz high resolution control voltage outputs using "8 + 8" Fast Hybrid PWM
which can be used to provide the correct charging voltage for an integrator circuit
to produce sawtooth or triangle waves or used to retro-fit systems which use the
Volts / Hz pitch system.
Pitch range of 8 octaves (MIDI keys C0 to C8) i.e. 32.5 Hz to 8.4 kHz
Pitch accuracy of 0.0006% of one semitone at Middle C
Pitch Bend (range can be set by user)
Guaranteed pitch stability (quartz controlled)
Pulse-Width control and Detune on every oscillator
Polyphonic, Unison and Monophonic modes
Velocity and MIDI-Volume outputs available in Unison mode
9 auxilliary triggers per chip for general use (5V for "note on" or 0V for "note off"
for drum machines etc.).
These can be chained so that 2 chips give 18 triggers
to a max of 4 chips giving 36 triggers.
MIDI Clock out in all modes
Built-in Test Mode to allow you to accurately calibrate conversion-precision
using just an audio amplifier.
PANIC MODE! Sending Program Change 9 resets main parameters
* Delay from chip to chip is less than 1 millisecond.
