6 years ago A vocoder would require a lot of new features and tech that Helm doesn't have right now. I'm not adding many features to Helm nowadays. Any work on Helm will mainly be bug fixes.
That said, I've got a newer synth in the works that will have many of the improvements that would have changed Helm too much for comfort.
Using feature request: external audio input #45 you could add a built in vocoder.
