ESI-32 Operation Manual
Ever wanted to add vibrato to a grand piano? Or bend its pitch? The
Realtime Control functions in the Preset Definition module can do this,
and lots more.
Pitch-Bending
First, let' s check out pitch-bending. Pitch-bend can be enabled or
disabled for any zone within a preset. Let's have pitch bend affect only
the lower half of the keyboard. Activate Dynamic Processing, 0. Select
Zone. Specify the upper half of the keyboard as the current zone.
Next key in Dynamic Processing, 8. Realtime Control Enable. Use the
cursor/page buttons to see a list of modulation destinations. Pitch will be
set to On. Press Off, and like magic, you can now pitch-bend only the
lower half of the keyboard. If modulation does not seem to be affecting a
zone, make sure that modulation is enabled.
Want to change the pitch bend range? Activate the Preset Definition
module, 6. MIDI.
Modulation Wheel Destinations
The ESI-32 offers two modulation options: Pre-programmed, which
adds a constant, selectable amount of modulation, and Realtime, where
the player adds in modulation by using one of the wheels or other
controllers.
Each wheel on your MIDI controller can be assigned to a particular
destination. For example, if the left wheel is assigned to pitch, then
rotating the wheel bends pitch. If assigned to the filter, rotating the
wheel varies the cutoff frequency.
Let' s set up for the next part of the tour. Choose preset 01 as the current
preset if it is not already selected. Activate the Dynamic Processing
module and assign the entire keyboard as the current zone if necessary.
Select 8. Realtime Control Enable. Use the cursor/page buttons to select
On for all of the Enable options. This will make it easier to hear the
results of the next series of experiments.
Now activate the Preset Definition module, 0. Realtime Controls. To
make "live" playing as simple as possible, the display works somewhat
differently for this module. The display shows:
