@JimHowell1970, we gotta get you on the Ochd train, the control is in what you patch where as each output is in relation to the others. Using outputs 3 and 8 will get you a very different result than 7 and 8. In the end it can be pretty expressive c.f. this piece where the Ochd is driving the whole melody https://stevehand.bandcamp.com/track/akemies-drone
