I'm sure, 'jaaa' may be helpful here. I use it in my audio DIY-ing. Of course, you must use JACK (with 'qjackctl') to be able to run multiple jaaa instances + other JACK-ready apps. 'jaaa --help' doesn't show very useful parameter "name": jaaa -J -name jaaa1 will run jaaa instance with "jaaa1" as JACK client name. LADSPA plugins has different oscillators, and here 'jack-rack' is usefull. P.S. Be careful with you tweaters when using white noise!

I must admit I've never tried performing with another os, but I like the fact I can run one script that sets my machine up for a gig (launches jack with the right settings, starts apps, connects them together etc), which takes a lot of the pressure away in the heat of the moment. I guess there is no one monolithic "point and click" app that will do all this in the way that live does, but lots of smaller ones, which in a lot of ways is preferable. cheers, dave

I dont get it, I dont know half the names you just told me.

So, what should I look for as an absolute beginner?

I'd actually really like to hear about other pieces of free software people on the list have used for live performance, the needs are quite different to other forms of music making.

I would say PD with csound running inside it. The new csound5 api object for PD is hella cool. Iain
