The CV Inputs
With the touchscreen encoders you can determine the
voltage scale for each of the CV input ports. The voltage
scale determines the voltage which will correspond to
100% modulation amount when using the CV input in the
mod matrix as a modulation source.
For example, if you have an analog envelope generator as
CV source which is going from 0V to 5V, you can set the CV
scale to 5V to get its full amount at 100% in the mod mat-
rix.
Or if you have an along LFO which only goes from -3V to
+3V, then you can set the CV scale to 3V to experience its
full modulation amount.
You can also set the CV scale by feeding the appropriate
voltage to the CV input and then tap on „Scan 100%“
Iridium is always capable to receive CV from -12V to +12V
even when the CV scale is much less, voltages above the CV
scale value will no be cut off.
For 1V/Oct pitch control (which is a standard for all Eu-
rorack modules/systems) set CV Scale around 2V and the
Mod Amount to 100%. A mod amount of 100% corres-
ponds in the mod matrix when modulated to pitch to 24
semitones or 2 octaves. Thus, the recommended value of
2V for the CV scale.
Since our ear is very sensitive to pitch variations and most
analogue sources are not precisely calibrated, you can for
precise tuning push the corresponding encoder to make a
fine or super fine control of the octave scaling.“
The Clock In/Out
Iridium is endowed with the ability to transmit or receive
clocking signals from a huge range of vintage devices.
The
Clock In
jack is intended to receive signals from an
external device so that the Iridium Sequencer and Arpeg-
giator can be synchronized to an external clock source.
The
Clock Out
jack sends signals to an external device so
that is can be synchronized to Iridiums tempo clock.
