• Channel: Sets the MIDI channel for the instrument’s output. If you set this parameter
to All, all events are sent with their original channel settings.
• Program, Volume, and Pan: The Program, Volume, and Pan parameters transmit program
changes, volume controller (#7), and pan controller (#10) data.
No data is sent until you select the corresponding checkbox. If the box is already
selected, any value alterations are sent immediately, and the values are also sent
whenever the track is selected.
To the left of the program number, directly to the right of the checkbox, is the Bank
Select parameter. If your MIDI sound source recognizes bank select messages (check
the device manual), you can switch between sound banks. If your sound source responds
to the standard Bank Select message (Controller #32), you can use this parameter
directly. If not, you can define your own Bank Select commands (see Mapped Instrument
Objects).
• Transposition: Defines the number of semitones that all note events are transposed by,
on output. Negative values transpose downward.
• Velocity: Allows you to increase or decrease the note on velocities of all note events,
by an amount between –99 and 99.
• Key Limit: The two note values of the Key Limit parameter define a pitch range. All
notes outside this range are ignored by the instrument when it plays a MIDI region. In
other words, this range of notes will not be played.
• Vel Limit: The two values of the Vel Lim parameter define a velocity range. All notes
with a velocity that falls outside this range are not played by the instrument.
• Delay: The Delay parameter causes all MIDI events to be sent early or late. This allows
you to compensate for any differences in reaction time between your various MIDI
devices. Use the region Delay parameter (in the Inspector’s Track Parameter box shown
in the Arrange window) to create rhythmic delay effects, as this allows longer delay
times.
• No Transpose: If the No Transpose parameter is active, all regions on any tracks played
by this instrument object are protected from transposition. In other words, the Transpose
Region parameter is ignored. This is very useful for instruments assigned to drum or
other samples—mapped across the keyboard on a single MIDI channel—as transposition
will trigger different sounds (rather than pitches) in these instruments.
