I'll try it

Just an idea...

Find the latency of each one by putting it alone in a project. Then when you have all 4 latency values you can compensate.

Example numbers:

Pitch -2 = 4000
Pitch -1 = 5000
Pitch +1 = 6000
Pitch +2 = 7000

So the max latency is 7000 samples. Now you know how much fixed delay to add after each pitch node

Pitch -2 needs 3000 delay
Pitch -1 needs 2000 delay
Pitch +1 needs 1000 delay
Pitch +2 needs zero delay
Original needs 7000 delay

That should align all the outputs and as long as you report 7000 (or whatever) to the host, everything should be in time.

That might be all nonsense, but it's worth a try.

Sanity check: 7232 samples at 44.1kHz = 163.9909297052ms

EDIT: see above

EDIT: don't do that. Looks like that call just returns the value set by Engine.setLatencySamples().

Use Tools > Check latency of signal chain to give you a real value.
