01V—Owner's Manual
Try calibrating the faders. See "Calibrating the Faders" on page 204
for more information.
This warning message appears if digital signals from the Digital Stereo
Coaxial In or Option I/O inputs are not wordclock synchronized with
the 01V. Make sure that all digital equipment is wordclock synchro-
nized to a common wordclock source. See "Setting the Wordclock"
on page 209 for more information.
Make sure the external wordclock source is turned on and that the
cable carrying the wordclock signal has not been disconnected. See
"Setting the Wordclock" on page 209 for more information.
On MIDI page 1, check the following settings: PORT, Tx CH, Rx CH,
and the Tx and Rx switches for Program Change, Control Change,
etc. See "MIDI Setup" on page 224 for more information.
Make sure that the 01V is configured to receive Program Change mes-
sages and that the MIDI Channels of the 01V and transmitting device
match. See "MIDI Setup" on page 224 for more information.
Perhaps the Program Change being transmitted is not assigned to an
01V scene memory? Check the mix scene to Program Change assign-
ment table. See "Program Change Scene Recall" on page 227 for
more information.
If the scene memory assigned to the received Program Change con-
tains no data, it cannot be recalled.
Make sure that the 01V is configured to receive Control Change mes-
sages and that the MIDI Channels of the 01V and transmitting device
match. See "MIDI Setup" on page 224 for more information.
Perhaps the Control Change being transmitted is not assigned to an
01V parameter? Check the parameter to Control Change assignment
table. See "Control Change Parameter Control" on page 229 for more
information.
Make sure that the BULK Rx switch on MIDI page 1 is turned on. See
"MIDI Setup" on page 224 for more information.
Perhaps the Local Control function on MIDI page 5 is turned off? See
"Local Control" on page 234 for more information.
Make sure the device number matches that of the MMC-compatible
recorder. See "MIDI Machine Control" on page 236 for more informa-
tion.
