Not for the faint of heart, I suppose!

Good catch! I meant to say that we cannot change the pitch, but that's not what I wrote, eh?You write in your readme : "...since the sequencer does not have a modulation destination for the oscillators".
Oh, sure! Already you want something to merge the modulation values with an existing sequence?The disadvantage is, if you record a new sequence (for using it together with the modulation), all the modulation values are set to 0.
