I read in the forum that a full service vocoder was probably beyond the 128 line code length. Any ideas if a Wah wah effect is possible?
How about frequency synthesis? I'm seeing just a few code examples.
Phase locked loop type effects?

All opinions and code welcome. We're just spinning up some proto dev boards now, so a ways off on coding.

A wah is possible, people have done them.

You can generate sine, tri and square waves or use the built in LFOs if you only need up to 20Hz.

PLL effect may be difficult if you mean locking to an incoming audio signal, if a signal is pure and regular you could look for 0 crossings and go from there. If the signal is more like music then that would be difficult
