Some alternatives would be: * Use something a bit more lightweight than Ardour, you mention ecamegapedal, did you try anything else? There is a bunch of similar apps. E.g. JackRack. I think there are some that don't require jack also... they might give better mileage. * don't run X, would definitely improve on the memory issue. Probably your best choice then would be to run ecasound directly (ecamegapedal is a kind of wrapper around ecasound). There is a bit of learning curve to understand all the features but ecasound is very capable. Jack would not be needed then either. /Robert > > Cheers, > Chris
