• XCTRL — External Controller
Like the TIMBR modulator, the External Controller (XCTRL) modulator can be assigned to
modulate any voice or effect modulation destination. Whenever you are playing a sound or
preset, you can press the Brightness/Timbre button three times to get to the XCTRL sub-page,
and use the Data Entry Slider to change the level of the XCTRL modulator.
In addition to using the Track XCTRL parameter, an external controller such as a Breath
Controller, Data Entry Slider, etc., that is received via MIDI from another synthesizer or MIDI
controller, will modulate any voice or effect parameter that has XCTRL assigned as a
modulator. On the MIDI Control Page, you select the MIDI Controller number of the external
controller that will be recognized by the TS-12.
You don’t have to be playing the TS-12 from an external instrument for this to work. For
example, if you have a keyboard with a Breath Controller:
1) Connect its MIDI Out to the TS-12 MIDI In
2) Make sure both instruments have controllers enabled (MIDI Control page)
3) Select Breath Controller as the external controller that will be received by the TS-12
(XCTRL=02, also on the MIDI Control Page)
4) assign XCTRL as a Modulator for LFO level, Filter Cutoff frequency, or some other manual
level within a voice
5) play the sound from the TS-12 keyboard, while blowing into the Breath Controller
connected to the sending instrument. The modulation will have the same effect as if you were
playing from the sending instrument.
• PRESS — Pressure (After-touch)
Pressure, also called after-touch, is a modulator which varies a manual level within a voice
depending on how hard you press down on a key or keys. After you have struck a key, and
while the note is sustaining, continuing to press down harder on the key brings in pressure.
The TS-12 keyboard generates pressure, and by using this modulator you can add a
tremendous amount of expression to your sounds without ever taking your hands off the
keyboard.
Pressure comes in two varieties — Poly-Key™ pressure (or Polyphonic pressure), which affects
each note individually, and Channel pressure (or Mono pressure) which affects all notes that
are playing when you exert pressure on any key. Only channel pressure can be generated on
the TS-12’s keyboard, but both types are received via incoming MIDI.
There is a Pressure parameter on a sub-page of the Performance Options page (press
Performance Options twice) which determines if pressure will be used by the program. This
control can also be set to NONE, in which case the program will not respond to pressure
internally, nor will it send or receive it via MIDI (see Section 5 — Preset/Track Parameters for
more details).
Note that not all sounds are necessarily programmed to respond to pressure. If pressure
seems to have no effect when you play certain sounds, it is likely that pressure is not assigned
as a modulator anywhere within the sound.
The effect of pressure as a modulator is positive-going only, though assigning a negative
modulation depth will cause increased pressure to reduce manual levels.
