The RECEIVE Page
Velocity MapReceive
The velocity map applies a preset curve to incoming velocity messages. It maps incoming
velocity levels to new levels that correspond to the eight dynamic levels used by the VTRIGs
and keymaps for velocity level selection. See Chapter 18 of the Musician’s Guide . Normally
you’ll leave this set to 1 Linear. Adjust this parameter’s value only when you need to alter the
K2661’s response to the velocity messages from a MIDI controller, for example, if you’re getting
too much or too little volume when you play, or when a sequencer is driving the K2661.
Pressure MapReceive
Like the velocity map, this determines how the K2661 responds to incoming pressure
(aftertouch) messages.
System Exclusive ID (SysExID)
The SysExID parameter differentiates between more than one MIDI device of the same model.
You won’t need to change the default setting of 0 unless you have multiple K2661s (or K2600s,
K2500s, or K2000s) receiving SysEx messages from a single source. In that case, make sure each
instrument has a different SysExID. Then you can direct SysEx messages to the appropriate
K2661 with the SysExID byte that’s included with every SysEx message. A value of 127 species
“Omni Receive.” That is, at this value, a K2661 responds to a SysEx message regardless of the
SysEx ID of the message (as long as the manufacturer and device IDs match—see Chapter 7 of
the Musician’s Reference for more information about System Exclusive messages).
SCSI ID
Use this parameter to change the SCSI ID of your K2661. You can ignore this parameter unless
you’ve connected a SCSI device (external SCSI disk or CD-ROM drive) to the K2661’s SCSI port.
You can use the SCSI port to chain up to seven SCSI devices to the K2661 (a total of eight devices
can be chained together); just be sure to set each one to a different SCSI ID. Most SCSI devices
available today make it easy to change their SCSI IDs, so you may not have to adjust this
parameter even if you have several SCSI devices connected. See Chapter 13 for more
information about using SCSI devices.
Bend Smooth
This parameter can improve your K2661’s performance when you’re driving it from a MIDI
guitar controller. Its default value is On.
You may nd that pitch bending seems to carry over from the previous note to the next note,
causing it to start on the wrong pitch. This is probably due to the automatic pitch smoothing
provided by the K2661. If this is happening, try setting the BendSmooth parameter to a value of
Off.
Local Keyboard Channel (LocalKbdCh)
Changing the setting of the Local Keyboard Channel parameter is useful only when your K2661
is receiving MIDI information from an external source—maybe you have a favorite MIDI
keyboard that you use to control all the gear in your studio, or you use a lot of outboard
sequencing. If you’re using the K2661 as a standalone music workstation or performance
keyboard, you can ignore this parameter.
If you do need to change the setting of the Local Keyboard Channel parameter, refer to Chapter
10 of the K2661 Musician’s Guide (provided on the CD-ROM).
