Program Change
Use MIDI Program Change messages to select (“trigger”) instruments for use.
Assign each instrument to a MIDI Program Change number, then send the program
change messages from your DAW or other MIDI device.
PLEASE NOTE: DAWs handle the sending of Program Change messages differently.
Please refer to their respective documentation.
Controller
With values between 0 and 127, Controller uses MIDI CC (Control Change)
messages to control instrument playback. For example, load 3 instruments, select
‘Controller’ within each of the Trigger Options, set them all to respond to MIDI CC 1
(the Mod Wheel), and define unique Mod Wheel value range for each instrument
(0-42, 43-87, 88-127). Now each instrument will only playback when the Mod
Wheel is within the value range.
Velocity Range
With values between 1 and 127, and measured by how hard you play your MIDI
keyboard, pads, etc., produce lower velocity values by playing softly, and playing
harder will produce higher velocity values. Being able to restrict the
Velocity Range of an instrument means you could have different instruments of
articulations playing based on how hard or soft you’re playing. For instance, create
a sustained instrument with an accent that only plays at higher velocities by loading
Violin Sustain and Staccato instruments, then restricting the Velocity Range of the
Staccato instrument between 110-127.
