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-3
s 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 D

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

Built-in Test Mode
to allow you to accurately calibrate conversion-precision
using just an audio amplifier.
