Contrast
Range: 1 — 8
This determines the contrast of the dis-
play. Adjust this as necessary for optimum
visibility. (At extreme settings, the dis-
play may not be readable.)
Dump Interval (DumpIntrval)
Settings: 50, 100, 150, 200, 300
This determines the length of time the
MU100R pauses when sending blocks of
data in the Dump Out functions. If the
receiving device fails to process the data
or displays a "buffer full" type message,
try setting this parameter to a higher value
and send the data again.
Thru Port
Range:
Some MIDI devices and sequencers are
capable of transmitting data over several
MIDI "ports," effectively breaking the 16-
channel barrier. When this data is received
via the TO HOST terminal on the
MU100R, this parameter determines
which MIDI port's data will be routed
through the MIDI OUT terminal. This
allows you to connect another multi-
timbral tone generator to the MU100R
and play back data over 48 independent
MIDI channels — 32 on the MU100R and
another 16 on the connected tone genera-
tor.
NOTE
The MU100R can receive Cable messages
(F5) when the TO HOST terminal is con-
nected to the serial terminal of a computer.
On the MU100R, MIDI
receive channels A1 — A16 are controlled
from Port 1, and channels B1 — B16 are con-
trolled from Port 2. If the software you are
using can
address separate MIDI ports, data can be re-
ceived over 32 channels simultaneously, al-
lowing 32 parts to be played with only one
serial cable. By connecting another multi-
timbral tone generator to the MIDI OUT ter-
minal of the MU100R and setting the Thru
Port function to a value other than 1 or 2,
you can play back data over a total of 48 MIDI
channels — 32 on the MU100R and another
16 on the connected tone generator.
