key difference of this delay vs. other varispeed delays is that record speed is always = 0 & the buffer is always overdubbed at play speed = 1. setting speed to -0.5 is a good demonstration of how this works.
Okay here’s a quick little example with some automation. I have a random value changing speed1 between 0.5 and 2. Speed2 is left alone at -1. I’m playing 5 notes from Operator into it, but I’m never changing the octave in which I’m playing - that’s all down to the automation of Speed1. It’s a bit clicky but the filter helps (and I don’t mind the clicks personally). I’ve been having fun turning the dry signal all the way down and then aligning my playing with what this device is feeding back to me.
Thanks again for sharing this! I will definitely be using it in the future.
