Basic TransMod system operations
Selecting a TransMod slot
Choosing a source for a TransMod slot. This example shows the
Monophonic source sub-menu (see 7:8 for more details)
Click in the middle portion of the slot (the part labelled ‘via’).
Clicking anywhere else in the slot selects it while also showing
either the source or scaler menu.
When viewing a TransMod slot in this way, any modulated
controls display their modulation depths, which can be edited on
the controls themselves.
Selecting a modulation source
Click on the upper segment of the slot. The source menu is
shown, allowing you to choose from a range of monophonic and
polyphonic sources.
See section 7:8 for full details of all available modulation sources.
Creating modulation depths
With a TransMod slot and the desired source selected, you
are ready to create modulation depths for parameters. This is
achieved by setting depths on the controls themselves.
Section 7:3 explains how to adjust modulation on controls.
The effect of TransMod modulation
When the modulation source varies, the values of any modulated parameters change proportionally within the defined
range according to the values they receive.
In effect, this type of modulation can be considered as ‘morphing’ – setting minimum and maxium values, with the
modulation source interpolating the parameter between these values.
Compared to a traditional mod matrix, the TransMod system offers some advantages. It is easier to keep track of large
numbers of modulated parameters. There is also no abstracted, table-based relationship between depths and parameters
– all depths are shown directly on the parameters themselves using the modulateable controls.
Virtually all synth parameters can be modulated using the TransMod system.
The only exceptions are the following:
• buttons
• gate source controls for Gateable Modulators (LFO, Envs etc)
• all parameters in the Arpeggiator, Keying controls, Glide controls and Settings sections, except the
Vel Glide
and
Pitch
Glide controls
Scaling
Each modulation slot in the TransMod system features an additional multiplying scaler.
By default, this is set to 1 (a numeric constant), meaning that the modulation source is mapped 1:1 with the destinations
– in other words, it is unchanged by the scaling function. Destination modulation depths can be multiplied by any available
monophonic or polyphonic modulation source, which is an easy way to create more complex modulation behaviours.
Choosing a scaler for a TransMod slot. This example shows the
polyphonic Synth sources (see 7:8 for more details)
Selecting a modulation scaler
Click on the lower segment of the slot. The scaler menu is
shown. By default, the scaler is set to ‘1’, which means the
source is unaffected.
See section 7:8 for full details of all modulation sources, which
can also be used as scalers.
Scaling examples
Note-on velocity (OnVel+) is very useful when used as a scaler.
For example, you could set up a number of parameter
modulation depths for a mod slot with an MRand source
(individual randomization for all destination parameter
modulation depths). Scaling this mod slot with note-on velocity
means that higher velocity notes result in higher random
modulations across the defined depths, while lower velocity
notes result in smaller depths.
You can use a performance controller (assigned to aftertouch,
the mod wheel or any MIDI CC) to manually control the depth of
a mod source over time.
Scaling is also very useful for delaying and gradually ramping in
LFO depth by multiplying an LFO source with the Ramp.
