Using TransMod modulation in Etch Red

Using multiple modulation sources

Select another modulation source, such as the Follower
source.

Note that the Pan parameter's TransMod amount knob
has snapped back to zero, due to the fact that no
modulation yet exists from the Follower source to the
Pan parameter.

Also note that the LED above the Pan's TransMod
amount knob has turned

re d. This indicates that the

parameter features modulation depths from a
modulation source

o th e r th a n th e c u rre n t s o u rc e.

C reate a modulation depth for a
parameter.

Note that the LED above the Rez
parameter's TransMod amount knob has
turned

y e llo w, which indicates that it

features a modulation depth from the

c u rre n t s o u rc e.

Also note that the LED to the top-right of
the Follower source's selector button has
turned

re d, to indicate that modulation

exists to one or more parameters from
that source.

Polarity: Unipolar / Bipolar operation

The LFO, S&H and Random sources can all be set to operate with unipolar or bipolar behaviour.

By default, the modulation from the S&H module acts
in 1 direction only as it outputs positive values from 0
to 1.

Deactivate the source's Unipolar button
so that it outputs negative and positive
values between -1 and 1.

This means that the Pan control is now
modulated in both directions about the
centre.

Source Mute buttons

Each source also features a Mute button. While this
button is activated, the modulation from the source
is disabled and the source therefore has no effect.
This function is useful for quickly establishing which
source may be causing a certain audible effect.
