Maybe not on the H9, but I'm 'seeing' a PIP window in H9 Control.  It only pops up the appropriate pattern graphic while adjusting one of the sequence parameters, then fades out.  I don't know how practical that would be on a small screen / iPhone, though.

Wow. I just noticed this thread. That's great spacejam!  Nice work.  

Yeah, we could certainly integrate these into H9 Control.  Part of the reason we'd never done so in the past was not really being convinced that we had the UI figured out.  But what you suggested sounds good…
