I have been using my Sequential Circuits Pro-One in the studio pretty often recently, so I decided to use it instead of of a newer keyboard for a recent performance. Unfortunately it did not work the way I had planned. Although I crave unpredictable behavior to stimulate the creative process, it is not exactly as pleasing during a live performance. The aging instrument did not stay in tune for very long and I was having trouble with the keyboard action. I imagine that it’s time for a thorough cleaning of the potentiometers and keyboard contacts. Despite these troubles, while scanning through clips recorded during the set, I came across this nice low frequency filter sweep and ran it through a ping pong delay.
