I use a plugin that I designed. It's like a looper effect but more organic, the sound that's 'looped' gradually fades out. I dislike loopers, they're either on or off, playing or not. I used it with bass for quite a few solo gigs, including with Steve Lawson last year. At the moment I'm using it more with piano, synth and electroacoustic sounds. This was done last night with it, I have a gig in Amsterdam at the weekend, this is an excerpt of a practice for that.
