Quoting Julian Storer <jules(a)rawmaterialsoftware.com>om>: This is truly great news. I really appreciate the effort you have put into the port, and to supporting Linux. Alas, ALSA. It's very unfortunate that you chose ALSA as the API for Linux. For me, applications without jack support are of zero interest. I live in a world where i can just connect every soft synth and drum machine and midi sequencer via jack to ardour, sync them via jack transport, do mastering inside this environment with Jamin. I'm capable of exporting & mastering faster-than-realtime, because all the software inside the "jack loop" will all run in perfect sync, in-time & on-time with jack instead of the soundcard. These are the benefits from jack. This is why I will give almost no consideration for an application which isn't jackd compatible. The worst thing that can happen is that you get disencouraged. I really do hope you won't get. Like Paul said, the jackd api is super-simple, you should have no trouble at all making a driver for JUCE which uses jackd. Please, pretty please, with sugar, whip cream and a coctail cherry on top. Don't give up! :) (And i guess you've already worked through the GUI & input issues of porting JUCE to Linux, so one more driver should be a breeze) Sampo
