in tempo, you set the master tempo for all sequencers, tempo
synced LFOs and tape.
you can switch between free, beat match (master) and sync modes, and you’ll also find the metronome here.
to set the tempo you have two choices:
turn the blue encoder,
or tap the tempo – do this by hitting the tempo key multiple times until you get the desired tempo.
pro-tip: hold shift + turn blue encoder to fine tune tempo.
to use the metronome, turn the orange encoder until you get a desired pitch.
to start the metronome, press play.
to turn off the metronome turn the orange encoder all the way to the bottom.
in free mode the tempo and tape speed are independent of each other.
no sync is transmitted from OP-1 and any incoming external sync is ignored.
turn the green encoder counterclockwise to select free mode.
in beat match OP-1 acts as the master clock source, sending MIDI sync over usb, that can be used to synchronize external gear.
beat match also means tempo and tape speed are linked together (note the green link symbol).
turn the green encoder to select beat match.
when selected, the tempo is linked to the tape speed. turning the white encoder will adjust tape speed and dim tempo, keeping both tape speed and tempo in sync. this way you can have recorded material on the tape remain in sync with sequenced material.
when beat match is active you will notice bar markers above the tape tracks while in tape mode. these bar markers are your guidelines when looping or recording in sync.
each marker represents the first beat of four. the space between each bar marker represents a full bar.
pro-tip: use shift + the arrow keys to loop and record different variations of full bars. while playing use shift + the arrow keys to easily move the playback loop between the variations.
explained further in the bars section 8.15.
this is great when playing live.
sync mode means OP-1 is listening to external MIDI clock, received over usb. this lets you slave tempo lock the OP-1 to MIDI time code (MTC) sent from external sequencers or workstations, indicated by EXT in the display.
if no external tempo is detected then internal tempo is used.
turn the green encoder to select sync mode.
in this mode tempo is not linked to tape speed (note the orange link symbol). adjusting tempo using the blue encoder has no effect.
tape speed can be changed using the white encoder.
pro-tip: tempo nudge can be used while OP-1 is synchronized to external tempo. use the arrow keys < and > to align the beat by adding or subtracting 1 MIDI clock per key press.
the bar markers mentioned in section 10.5 is present in this mode also.
PO sync can be used to sync pocket operators directly from OP-1. in this mode the OP-1 output signal is split into dual mono, L being the click track used for pocket operator synchronization, and R being a mix of the usual audio signal.
turn the green encoder to select PO sync. green link text behaves as beat match (OP-1 is master). orange link text behaves as sync mode
(OP-1 is synchronized to external MIDI clock).
example: connect a 3.5 mm stereo cable from the OP-1 output to the input of the pocket operator. set PO unit to SY4. press play on PO unit and finally press play on OP-1. both units will start in sync and the audio from OP-1 will be mixed with the audio of the PO unit.
for further info on how to operate pocket operators please check the guides
a variation of this mode is 1/16 sync, sending a double tempo click track that can be used with eurorack etc.
while in PO sync hold shift and turn the green encoder to toggle 1/16 sync.
