I have to set ASIO to 1024 samples when using Melodyne but there is no way to track at that setting because of latency (delay); consequently, I reset that all the time.
Sometimes, I lose audio when going from 1024 to a smaller number for tracking and have to reboot--but not always.
1) I am pretty sure the "buffer" is
I/O buffer (Advanced Mode: Preferences->Audio->Synch and Caching (the disc read/writes to smooth ARA performance)) and
not Audio buffer. I remember early on I jacked my ASIO buffer through the roof and still got that warning... but if you set I/O buffers to 1024 that warning goes away (just verified this actually).
2) Someone involved in the beta testing chimed in on a thread (I wish I could give them credit), and said that was implemented as a short-term fix and was resolved in a later build of Melodyne (i.e. no longer applicable), but is still encoded into the program.
3) Bottom line, can blow this warning off unless you see issues, but be wary about that warning dialogue causing issues like in #5 above.
