you can use the OT midi sequencing to do plocks-lite, they are not as powerful through midi as they are native, on the A4 the plocks are relative to the A4 sound, from the OT they will be absolute, until the next one, the only way to get full control (similar to A4) is to plock every step, then it will still not be anywhere near as powerful as you can only plock ten destinations, and the plocking will be by low-res midi compared to some params on A4

You’d be better off plocking the Performance params on the A4 (a4 can’t do this) from the OT and do all the A4 sequencing/locking internally, uou could even program Aftertouch/pitchbend from OT

I can only speak for myself, just got an OT recently and it is not something i imagine i’d try to do given how superior the A4 native control is !

Think of the Octatrack as primarily a performance sampler with an additional secondary midi capability, i’ve yet to crack it
