Pitch, Gate
These inputs are related to various functionality within various TransMod sources and internal
modulator devices in Etch Red.
The Pitch input is used for:
the Pitch TransMod source, which lets you modulate parameters according to incoming note
input
the filter Key Track function, which allows precise note-to-frequency tracking for the filter
cutoff
The Gate input receives velocity-sensitive gate C V signals and is used for the Envelope modulator
and also the Velocity and Random TransMod sources.
Note: Etch Red receives MIDI note input from Reason's MIDI input and sequencer. This input, in
addition to the rear panel Pitch/Gate inputs, is used for modulation functions which require a pitch
or gate input.
LFO1 and LFO2 Retrigger
These inputs accept gate-type C V signals - when a suitable gate signal is received at each input,
the relevant LFO is retriggered (it is restarted according to its current Phase setting).
S&H Retrigger
This input is intended to be patched to an external gate or square-wave LFO source to trigger the
Sample & Hold modulator function in addition to its internal clock.
TransMod modulation CV outputs
These C V outputs provide the output from Etch Red's internal modulators so that they can be used
to modulate parameters elsewhere within Reason. Simply patch the outputs to suitable C V inputs
on another Reason device. The LFO1, LFO2 and S&H outputs transmit unipolar (0 to 1) or bipolar (-
1 to 1) modulation depending upon the state of each modulator's Unipolar button, described in
chapter 3.
