176 Appendix B Logic Control—MIDI Implementation
LCD
Received: <Hdr>, 12, oo, yy, …, F7 Update LCD
Transmitted: None
oo Display offset to write from:
00 thru 37 for upper line,
38 thru 6F for lower line.
yy Data: ASCII equivalents for display characters written from left to right,
including line wrapping between upper and lower line. Up to 100 data bytes
may be sent in one message.
Example:
• The following message writes “Hello” to top left of the LCD on a Logic Control master
section.
F0 00 00 66 10 12 00 48 65 6C 6C 6F F7
Notes:
• There are 7 displayed characters per channel, with the exception of channel 8, which
displays only the first 6 characters. Internally however, the LCD stores 2 x 56
characters.
• In most cases you will use the LCD in a scribble-strip fashion (text above each
channel). In this case, you should use only the first six characters per channel to leave
space between channel text.
• The lower line can be switched into meter mode. See Metering section on page 179
for further details.
• While the LCD switches between horizontal and vertical metering mode, it ignores
LCD messages. After you sent an LCD metering mode change message, you should
delay LCD messages for at least 600 ms.
