Teenage Engineering OP-1 Finger Sequencer Demo 

The new operating system for the OP-1 was released today. I thought I'd make a quick video to show how cool this thing is.
I made a few sequences. Most were 8 steps long, but I also had a 5 and a 9 step in there. You can set it into three different modes: join, replace, fill in. Join is definitely the most fun.
