Ok, let's say I'll do what multiple people proposed here: one jack client per effect + only data exchange between effects via jack ports.

Then see this example:

    piano roll   ----- (notes) -----> synthesizer

How should one transfer notes using a jack buffer? Of course, one could make a structure to transfer notes, cast this structure to const char*, and *hope* it fits into the port buffer. Is there any better way? Maybe a "custom port type"?
