It’s good enough for me for realtime use, I have a commercial licence and am now shipping a product with it: https://www.caelumaudio.com/CaelumAudio/?Page=Choric Best demo hearing the pitch shift do its thing is the instagram reel part way down the page. Maybe because I’m blending the signal that the latency isn’t too much an issue though - I’m reporting roughly 10-20ms latency to the host.
That being said, the plugin also installs a “low-latency” version with pitch shifting disabled specifically for live performance as this was heavily requested.
