step sequencer sync

[Sounduke]

Hi Jonas,

I was thinking if it is possible to add a trigger sync to helix's step sequencer
in the next update.

In live performances, even a well trained pianist may have a slight offset
when striking a key. Being the step sequencer very precise, this leads to slightly
out of sync sequences.

I would be very grateful if you would consider this proposal from a
long time user of helix.

Thank you for your attention.
