Using JamSync
Teaching the SDRUM and Recording Loops
When using a JamSync-compatible JamMan looper with the SDRUM, the looper must be armed for recording
either before playback is initiated in the SDRUM or during playback and before the SDRUM reaches bar 1 (the
beginning of the drum pattern). It’s at bar 1 that the SDRUM will tell the slave device to begin recording, but the
slave must be armed for recording in advance.
To use the SDRUM with JamMan loopers:
1. With an empty part selected, press the FOOTSWITCH on the SDRUM and teach it a drum pattern by
scratching the guitar or using the KICK/SNARE pads.
2. When finished teaching the SDRUM, press the FOOTSWITCH once to set the loop end point. The drum
pattern will automatically begin playing in a repeating loop and the PLAY LED will light solid green.
3. Press the FOOTSWITCH on the slave looper to arm it for recording. The looper can be armed at any
time while the SDRUM is playing. The looper's REC LED will flash red to indicate it is armed for recording.
Recording will begin once the SDRUM makes another pass of the beginning of the drum pattern (the REC
LED will light solid red on the slave device when recording begins). Once recording has begun, play the
guitar part. The recorded loop must be the same length as the SDRUM's loop or a multiple of it.
4. When finished recording to the slave device, press the slave’s FOOTSWITCH once to set the loop end point.
The phrase will automatically begin playing along with the SDRUM's loop and the PLAY LED will light solid
green on the looper.
5. Repeat steps 3-4 to record loops for any other loopers connected via JamSync.
6. Hold the FOOTSWITCH on the SDRUM to stop loop playback on all devices.
NOTE: The SDRUM has some capabilities that are not currently supported by any JamSync slave devices:
• Variable Tempo – If a loop is recorded on a JamSync slave, and then the tempo on the SDRUM is
subsequently changed, the slave will lose sync with the SDRUM. It's recommended that the tempo be
dialed in for a song on the SDRUM before recording to a JamSync slave.
• Multiple Parts – When changing parts on the SDRUM, the JamSync slave will not be aware of the
change. So if the slave's loop length is compatible with the new part (e.g., it is an integer multiple of
the new SDRUM part's loop length) then the device will stay in sync; but if the slave's loop length is not
compatible, it will lose sync with the SDRUM.
NOTE: Some JamSync-compatible loopers support a “Sequential Slave Recording Method” (recording loops
to one looper, then immediately to the next, etc.). Note that the SDRUM does not support this functionality.
To play the SDRUM and slave devices:
1. Press the FOOTSWITCH on all slave devices to arm them for playback. The green PLAY LED will flash on
each.
2. Press the FOOTSWITCH on the SDRUM to start playback. Each slave will start playing in sync with the
SDRUM and its LED will light solid green.
3. Hold the FOOTSWITCH on the SDRUM to stop loop playback on all devices.
