emulating JX3p sequencing

so like the title says,  trying to emulate the action of the onboard sequencer in a JX3p or sh101  ie,  enter some notes and chords into the 16 steps,   but then have the sequence advance only by means of a trigger from a midi note..  (the roland used a trigger input.. even better if that were possible)   

 

any ideas for a workaround that could achieve a similar result?   could this be implemented?   

 

There is an open item in the wish list which would allow to do this:


Trigger steps from another track:


 

(steps could then also be triggered from any MIDI input, not only from another track)

Best Regards, Thorsten.

cool!
