It was highly annoying, luckily Sequential diagnosed the issue and it required a repair to the main voice board which they fixed very quickly.
I was hoping it was just calibration or something I could do without needing to send it back. I need to capture the "whistling" adequately, as the test tones I've done so far are not convincing. I really feel that if I could warp someone here, and have them hear it first hand they would agree something is not right.
Edit: Here is another test tone
https://drive.google.com/file/d/1ILeBZo6sgiLATsM8lMnw-1ZOPFzTSqgt/view?usp=sharingI started this one with silence to show it's not my audio set up, I also did not EQ this test tone, or exaggerate it in any way.
Do you have another hardware synth that you can plug into the same inputs on your audio interface and same cables you’re using on the Pro 3 and see if that sound is still present?
Yes - this is coming from the Pro 3. I plugged it directly into my monitors to bypass the audio interface, then confirmed it with my studio headphones.
Worst case return your Pro 3 and get another one because mine doesn’t have any artifact present. I love the Pro 3 very much.
Yes - that is what I want to do, and have already contacted Sweetwater.
It's like eating custard with sand in it, as it doesn't take much sand to ruin a great custard
The moments it really stands out, is when the Pro 3 is producing some lush and evolving lows (custard), and then this high pitched teapot whistling ruins it (sand). I've noticed that when I first power the synth on, it doesn't happen for a few seconds, then fades in.
