A few years back I discovered the music of Steve Lawson and Matt Stevens. These (mostly) solo artists make extensive use of loops in their performances to build layers of sound into complex arrangements. Steve uses the Looperlative and Matt has a Line 6 pedal. I have a looper in my Roland Cube amplifier, but have only done some simple stuff with it, such as this jam
I get some musical ideas based around loops that I would like to play with. These are generally for guitar or vocals. I want to be able to record a series of looping segments and then play something over the top, recording the results into Ardour. I suspect there may be some Linux tools that would allow this. I'm aware of Freewheeling and SooperLooper, but have not tried them as yet. I think they are aimed at live performance, but I would hope they could work in a studio too. Dave Phillips has written a pretty good summary of the options. I would hope that I could use my nanoKontrol to turn loops on/off and adjust levels.
I shall try to have a play soon, but would be interested to hear from anyone with experience of these tools.
