Section 7
• PRESS — Pressure (After-touch)
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. The EPS-16 PLUS receives both types via MIDI.
There is a performance parameter on a sub-page of the EDIT/Instrument page
which determines which of the two types of 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
the discussion on Performance Parameters in Section 3 — Instruments and
Banks 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
the programmer did not assign pressure as a modulator anywhere within the
program.
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.
• WL + PR — Wheel + Pressure
Another combination modulator. When selected, either mod wheel or pressure
will affect the level which is being modulated. This can be good for modulating
LFO depth when using the LFO for vibrato. That way the player can use either
to get vibrato.
