Can you be more specific? When you say ‘trigger it according to a sequence on the Octatrack’, do you mean so that the synth follows the pitch of the sequence programmed in the Octatrack? If so, the answer is no, as the Octatrack does not send control voltage for the synth to respond to.
However, it is possible to use the Cue out of the Octatrack to send an audio pulse/gate of some kind that could trigger the internal sequencer on an external synth, or, say provide a clock source for a module such as Rene, or the Wogglebug. But that would be simply providing a gate to ‘drive’ the destination forward, it would not be sending any pitch information.
The Analog Four/Keys are the only Elektrons which would perform this duty. But any of them could send a gate signal as in the second example.
