This is basically my plan. Use Ecamegapedal to hold it all together and use a MIDI pedal board such as http://www.behringer.com/FCB1010/index.cfm?lang=ENG. I intend to write my own plugins and if necessary, add to ecamegapedal to add the midi control routing unless I can find another way to do this. There are a couple of things one would want to be able to do. One is to change patches which could mean changing setting on all the effects wholesale or changing which effects are loaded. However, this might it difficult as pedal and switch assigments would change and the last thinkg you want is too much changing of what they do. So, the midi routing could be added to ecamegapedal which can then dela with patch changes which would include routing of the midi, or you route the midi separately to the various effects. My preference would be to use megapedal but I don't know if it handles patch changes. If it does, great. If it doesn't, should it or should something else be created. I would love to discuss this with the megapedal writers, but I don't have enough knowledge yet of megapedal. I guess, as with most things Linux, you can roll it yourself or help get it added. -- Veronica Merryfield, somewhere in Cambridgeshire, UK ----- Original Message ----- From: "Robert Jonsson" &lt;rj(a)spamatica.se&gt; To: &lt;linux-audio-user(a)music.columbia.edu&gt; Sent: Sunday, July 04, 2004 12:16 PM Subject: Re: [linux-audio-user] real-time audio effects (was: plugging a bassguitar in a linux box) söndagen den 4 juli 2004 12.12 skrev caffeine: I think ecasound would be an excellent choice, especially as you are low on CPU and ecasound does not require guis and such stupid things. :) Do remember that ecasound supports LADSPA plugins so you are in no way limited to the built in effects of it.

It's not perfect though, some JACK apps decide to crash at random intervals if left running for too long and I've noticed that one bad app can ruin the whole signal chain. -lee
