TO HOST
Dump Interval (DumpIntrval)
Settings: 50, 100, 150, 200, 300 (ms)
This determines the length of time the
MU128 pauses when sending blocks of
data in the Dump Out functions. (page
162.) If the receiving device fails to pro-
cess the data or displays a “buffer full”
type message, try setting this parameter
to a higher value and send the data again.
NOTE
Setting this to one of the smaller values lets
you shorten the data transmit time; however,
doing so may result in data errors on the re-
ceiving end.
Thru Port
Range: 1 — 8
Some MIDI devices and sequencers are
capable of transmitting data over several
MIDI “ports,” effectively breaking the
16-channel barrier. When this data is re-
ceived via the TO HOST terminal on the
MU128, 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 MU128 and play back
data over 80 independent MIDI channels
— 64 on the MU128 and another 16 on
the connected tone generator.
NOTE
The MU128 can receive Cable messages (F5)
when the TO HOST terminal is connected to
the serial terminal of a computer.
On the MU128, MIDI receive channels A01
- A16 are controlled from Port 1, channels
B01 - B16 are controlled from Port 2, chan-
nels C01 - C16 are controlled from Port 3,
and channels D01 - D16 are controlled from
Port 4. If the software you are using can
address separate MIDI ports, data can be re-
ceived over 64 channels simultaneously, al-
lowing 64 parts to be played with only one
serial cable. By connecting another multi-
timbral tone generator to the MIDI OUT ter-
minal of the MU128 and setting the Thru Port
function to a value of 5 or higher, you can
play back data over a total of 80 MIDI chan-
nels — 64 on the MU128 and another 16 on
the connected tone generator.
