It’s a great sequencer! I’ve been using it since last summer I think, and though I also got a hermod a few months ago, which is currently sitting right next to it, I keep coming back to the performer, and will be removing the hermod soon.
I made a few stabs at demoing some of it at the end of this video - sorry you’ve to wade through some crap before it starts. https://youtu.be/uTVE36UgAvI?t=360 (I was hoping to embed this, but can’t figure out how)
And forestcaver’s fix is a really elegant one, for a problem that might not happen to some/most people. For instance, in my Make noise shared system case, I never have the power on problem, but in my large cabinet at home I typically have to start the system twice to get the performer to come on. Before he came up with his solution I had already found this - the WMD Soft Start module - https://wmdevices.com/collections/modular-accessories/products/soft-start-module - which also fixes it.
