System Exclusive Protocol
K2vx System Exclusive Implementation
30-6
equal to the new bank number. If the operation canÕt be completed because of a bad type or
bank number, the ENDOFBANK message will specify the old bank number.
PANEL = 14h buttons(3n)
Ésends a sequence of front-panel button presses that are interpreted by the K2vx as if the
buttons were pressed at its front-panel. The button codes are listed in a table at the end of this
chapter. The K2vx will send these messages if the Buttons parameter on the XMIT page in MIDI
mode is set to On. Each button press is 3 bytes in the message. The PANEL message can include
as many 3-byte segments as necessary.
Byte 1 Button event type:
08h Button up
09h Button down
0Ah Button repeat
0Dh Alpha Wheel
Byte 2 Button number (see table)
Byte 3 Repeat count (number of clicks) for Alpha Wheel; the count is the delta (difference)
from 64—that is, the value of the byte minus 64 equals the number of clicks. A Byte
3 value of 46h (70 dec) equates to 6 clicks to the right. A Byte 3 value of 3Ah (58
dec) equates to six clicks to the left. For example, the equivalent of 6 clicks to the
right would be the following message:
(header) 14h 0Dh 40h 46 (eox)
For efÞciency, multiple button presses should be handled by sending multiple Button down
bytes followed by a single Button up byte (for incrementing with the Ô+Õ button, for instance. )
