1.1 Using Etch Red in Reason
Etch Red is a Reason Rack Extension. In use, it is operated in a very similar way as any other
device within Reason: the front panel houses Etch Red's controls and built-in modulation functions,
while the rear panel features a number of audio and C V inputs and outputs.
Rear panel audio and CV/gate connections
Main audio in/out
Etch Red features stereo audio inputs and outputs in the Main In/Out section. If only one of the
inputs is connected, this signal is duplicated to the other channel.
Filter FM audio inputs
The Filter1 FM and Filter2 FM inputs override the default routing of LFO1 or LFO2 to the audio-
rate filter FM function on each filter.
These inputs are for audio signals only - C V sources should be connected to the C V1 or C V2 inputs
and routed to the filter cutoffs via the TransMod system.
Override audio inputs
These audio inputs override the default signals used for the Follower (Envelope Follower) and
Sample & Hold internal modulators in Etch Red.
Follower
With nothing patched to this input, the Follower module follows transients in the input audio signal
(audio routed to the Main input). Patching an external audio signal into this input makes the
Follower track transients in this signal instead.
Sample & Hold
With nothing patched into this input, the Sample & Hold module acts on a dedicated internal noise
generator (the source that is sampled and held). If an external audio signal is patched into this
input, it is used instead of the internal noise source.
TransMod modulation CV/gate inputs
CV1 and CV2
These inputs are used for the C V1 and C V2 TransMod modulation sources. Each of these inputs
features an attenuator for fine-tuning the level of incoming C V signals.
