Hey Alex<br>
<br>
I'm just trying this out. I didn't have a sound file I particularly<br>
wanted to try, so I just plugged in an osc~, and what I found on the<br>
output: a mixture of the original tone with the shifted one.<br>
<br>
So, the shifted tone was clearly audible, but as I shifted the<br>
frequency, I could hear first the beating of the tones then two tones.<br>
<br>
And upon reading into the patch, that's clearly what you're doing in a<br>
subpatch, but I don't get why?<br>
