Prg, Vol, and Pan
The Prg, Vol, and Pan parameters transmit program changes, volume controller (#7) and
pan controller (#10) data.
You can edit the values of any of these parameters, but no data will be sent until you
check the corresponding box (by clicking on it). If the box is already checked, any value
alterations will be sent immediately, and the values will also be sent whenever the track
is selected.
To the left of the program number, directly to the right of the checkbox, you’ll see the
bank select parameter. If your MIDI sound sources recognize Bank Select messages
(check their manuals), you will be able to switch between sound banks. If your sound
sources respond to the standard Bank Select message (Controller #32), you will be able
to use this parameter directly. If not, you may define your own Bank Select commands
(see “Defining Custom Bank Selects” on page 169).
Transpose
The Transpose parameter defines the number of semitones that all note events will be
transposed by, on output. Negative values transpose downwards.
Velocity
The Velocity parameter allows you to increase or decrease the “note on” velocities of all
note events, by an amount adjustable between
−
99 and 99.
Key Limit
The two note values of the Lim parameter define a pitch range. All notes outside this
range will be ignored by the instrument when it plays a MIDI Region.
Vel Limit
The two values of the VLim parameter define a velocity range. All notes with a velocity
that falls outside this range will not be played by the instrument.
Delay
The Delay parameter causes all MIDI events to be sent early or late. This “delay” ranges
from
−
99 to 99 ticks. This allows you to adjust for any differences in reaction time
between your various MIDI devices. Use the Region parameter of the same name to
create delay effects, as this allows longer delay times.
