Troubleshooting
If the MC-808 does not function in the way you expect, first check the following points.
If this does not resolve the problem, consult your dealer or a nearby Roland Service Station.
* If any sort of message is being displayed on the screen during an operation, refer to
“Error messages”
(p. 142).
Q: The Editor doesn’t work even though the MC-
808 is connected via USB to my computer.
A: Here are some possible reasons for this
problem.
• USB mode is not set to MIDI
With the factory settings, the MC-808’s USB mode is set for file
transfer (Mass Storage). If you want to use the Editor, you must
change the USB mode to MIDI mode (p. 132).
• The USB Driver is not installed
Install the USB Driver for computer from the included CD-ROM
(
p. 136
)
.
• MIDI settings are not made correctly
In the Editor’s [Settings] - [MIDI device settings], select Roland
MC-808 as the setting for the MC-808’s Input and Output.
Q: Are the MC-808’s sounds compatible with
previous models of groovebox (MC-909,
MC-307, MC-505, MC-303, D2)?
A: They are not compatible with previous
models of groovebox.
The MC-808’s sounds were newly created specifically for this
product to meet the needs of today’s music.
Q: Even if I use the MC-808’s motorized
faders to increase the Resonance as far as
possible, the setting does not reach 127.
A: When you use the motorized faders to
increase the MC-808’s RESONANCE as far
as possible, the maximum value will be
115 by default.
This is in order to prevent excessive oscillation from distorting
the sound.
You can use the
“Reso Limiter”
(p. 121) parameter to adjust the
maximum RESONANCE value that can be set by the motorized
faders.
Q: The MC-808’s motorized faders don’t move
automatically.
A: The MC-808 has a setting that lets you choose
whether the motors of the motorized faders
will always be active. If you turn the [SYSTEM]
- [PANEL] - [FADER MOTOR SW] setting ON, the
faders will move automatically.
Also, the MC-808’s motorized faders are touch sensitive, and
will automatically switch from automatic to manual operation
when you touch a fader.
To return a fader to automatic operation, you can hold down
the [PART LEVEL], [PART PAN], [SYNTHESIZER 1], or
[SYNTHESIZER 2] button (whichever is currently selected) and
press the part button that you want to return to automatic
operation. Alternatively, you can press the [EXIT] button to
return the faders to automatic operation (p. 23).
Q: When playing patterns successively, can I
play back while preserving the BPM of the
first pattern?
A: The MC-808 is designed so that each
pattern plays at the optimal BPM even
when patterns are played back
successively, but also provides a function
that lets you preserve the BPM of the
pattern you first selected.
Turn the [SYSTEM] - [SEQUENCER] - [BPM LOCK] setting ON
(p. 119).
Q: The octave shift buttons don’t work.
A: Could a rhythm set be assigned to the
currently selected part (the current part)?
If you’ve selected a patch, the octave shift buttons will operate
at all times. However, if you’ve selected a rhythm set, the octave
shift buttons will generally be inactive.
This is because a rhythm set consists of only sixteen sounds
assigned to the B3–D5 range, and the MC-808 is designed so
that you’ll always be able to play the sounds of the rhythm set
from the pads.
However, there may be times when you want to use the MC-
808’s pads to play an external MIDI device from a part for
which a rhythm set is selected, and the MC-808 does provide a
function that lets you enable the octave shift buttons in such
cases. Turn the [SYSTEM] - [SOUND] - [RHYTHM OCTAVE
SW] setting ON (p. 121).
