I tried the ‘sound in’ synth on a WIN-10 PC using a USB camera for the microphone. It works , but there is an obvious latency problem . Does anyone use this synth sans problems ? Perhaps the USB is the problem ? My goal is to use ’ sound in ’ along with ’ record ’ to mix voice ( and whatever ) with Sonic-Pi scripts . Sort of a ’ one program does all ’ mixer - recorder … Caveat : My WIN PC is the newer cheaper type without dedicated audio input jacks. ---

The `set_audio_latency!` function is made to alleviate this problem in particular. Try experimenting with it a bit and see if it helps ---

Thank You ! On experimenting the immediate big problem is that (singing with Pi-Piece) my voice is delayed over the monitor making everything awkward from the get-go. I’ll work on another recording method. I’d rather use R-Pi than Win 10 anyways …
