If large amounts of noise are being introduced by distortion effects or other effects processors connected to the input jacks, it may be that
when Auto Recording is set recording is being triggered by that noise. Either raise the auto record trigger level (p. 33), or reduce the noise, for example by lowering the
to ON distortion level.

Action
Try substituting with other connection cables.
Confirm the connections to other devices (p. 6).
Confirm the settings for connected devices.
Adjust sliders/knobs to the suitable positions.
Adjust the phrase memory level. Confirm that the phrase memory is not such that the
phrase memory level is adjusted by an EXP pedal or other such controller (p. 23).
Confirm the output settings.
"Using the Same Output Jacks for All Phrase Memories (Input/Track 1, 2, 3/Rhythm Output)" (p. 33)
"Assigning a Track's Output Jacks (Output Select)" (p. 19)
"Setting the Output Jacks for the Rhythm Sound (Rhythm Output Select)" (p. 26)
"Setting the Output Jacks for the Sounds Being Input (Input Output Select)" (p. 20)
Check the track's STATUS indicator to see whether the track has been recorded. If the STATUS
indicator is unlit, nothing has been recorded.
Adjust knobs to the suitable positions (p. 6).
Confirm the output setting.
"Using the Same Output Jacks for All Phrase Memories (Input/Track 1, 2, 3/Rhythm Output)"

"Setting the Output Jacks for the Sounds Being Input (Input Output Select)" (p. 20)
Use a connection cable that does not contain a resistor.
With the RC-300, you cannot switch phrase memories while any screen other than the Play
screen is displayed. Press the [EXIT] button to return to the Play screen.
If memory is insufficient, initialize any unneeded phrase memories (p. 15) before recording or
overdubbing.
When recording with Loop Sync set to ON, once the end of the longest track is reached, the
RC-300 automatically switches to overdubbing. "Aligning the Beginning of Loop Playback
(Loop Sync)" (p. 18)
You cannot record/overdub to tracks set to ONE SHOT. If you want to record/overdub,
change the Play Mode setting to LOOP.
You cannot change the phrase memory tempo during recording or overdubbing. Change
the tempo while the performance is stopped or being played back.
When Tempo Sync is not set to ON in a track, the playback speed does not change even if
the phrase memory tempo is changed. To match the playback speed to the phrase memory
tempo, set the track's Tempo Sync setting to ON (p. 18).
Try replacing the MIDI cable.
Confirm that both devices are set to the same MIDI channels (p. 34).
Check the Program Change Message Transmit ON/OFF (p. 34) and Control Change Message
Transmit settings (p. 23).
The RC-300 will not receive MIDI clock or MIDI start/stop data from an external device.
(The RC-300 cannot synchronize as the slave.)
If you want to synchronize the RC-300 with an external device, the RC-300 must be assigned
as the master.
If you want to use start/stop for synchronization, you must specify "ALL PLAY/STOP" or "TR1–3
PLAY/STOP" as the assignment target for the assignment source "SYNC START/STOP" on the slave
unit.
Do not change the phrase memory tempo of the master unit during synchronized performance.
Check the connection (p. 36).
Set the USB Mode to "STORAGE" as described in "Using USB to Exchange Files with Your
Computer (USB Mass Storage)" (p. 36).
