7:5 Gateable modulators
The term ‘gateable modulators’ in DCAM: Synth Squad refers to LFOs, Ramps and Envelopes. LFOs and Ramps are
actually ‘triggered’ rather than gated for a variable duration – they are called gateable modulators here in order to simplify
the interfaces of the synths.
Gateable modulators can be gated or triggered with a number of selectable gate sources, and even with each other to
create very complex modulation effects.
While some gateable modulators feature direct routings and depth controls for commonly used parameters in some of the
synths, they are all available as TransMod sources to create more complex sounds. Inverted envelopes and ramps are
also available.
Types of gating behaviour (Gate control settings)
Setting the Gate source for the LFO in Strobe.
Note that the Gate control is not labelled on the Ramp
modulator.
Poly
This setting represents normal polyphonic gating mode.
The gating behaviour depends on the state of the
Retrig
button in each synth’s Glide controls section.
PolyOn
This gating mode disregards the
Retrig
button setting entirely.
When using this mode, a gateable modulator is always gated
or triggered by key-on events for each voice.
Mono
In this mode, a gateable modulator is gated/triggered by the
first key-on when all notes are off – subsequent keys that are
played without releasing all keys do not re-gate the modulator.
This mode is especially useful when using the arpeggiator, to
use an envelope or LFO over the sequence of notes rather than
on each note. It can also be used when you need an LFO to
modulate parameters of all voices together, rather than modulating each voice independently of the others.
Song
The main function of the Song gate type is for providing a ‘free-running’ LFO which is not triggered by key-on events or
other modulators.
When playback is started in your host, the LFO is triggered and runs freely afterwards. This allows free-running behaviour
but with repeatability – each time you play through your song it sounds identical.
When playback is stopped in your host, the LFO simply runs freely, continuously. In such a situation, it behaves just like a
standalone synth that features a free-running LFO.
You can use this gate type as a gate source for the Ramp, ModEnv and AmpEnv modulators. This is to achieve a number
of purposes – for example, when using looped envelopes as substitute LFOs, you may want the phase to be dictated by
song playback. It can also be useful for creating very long envelopes for drone sounds over the length of a song.
Other gateable modulators
Each of the gateable modulators can be gated or triggered by each other – the gating or triggering occurs when the gate
source reaches a value of 1.
For example, if you set the ModEnv to be gated by the LFO, the ModEnv is retriggered every time the LFO reaches its
highest point (1).
