Is there a vocoder that doesn't crash Waveform?

[pough]

So far I've tried Vocodex (Image-Line), fbvc64 (Full Bucket) and TAL-Vocoder (Togu Audio Line) and all three have crashed Waveform 11.

iZotope VocalSynth seems to work just fine. Note that I am on a Mac, and that I have the original VocalSynth (haven't upgraded to 2 yet).

On Windows 10 iZotope VocalSynth 1&2 are fine. Maybe try the Melda vocoder.
