Many analog instruments need to warm up before you can use them, anything with tubes for example needs to get cooking before it really does its thing. The Buchla Music Easel does not have tubes but it does need to warm up. I’ve heard anywhere from 5-20 minutes of just running before it’s in operating range. In practice I’ve never waited that long. Sometimes I wait a few minutes, sometimes I just dive in. This leads to confusion and chaos, as I learned yesterday. The sound of the oscillators drastically changes during that warm up period, I didn’t realize just how much they changed and how important that warm up period is.
Now I do.
