Excellent. You don't know how long I've been waiting for something like this.
Talking of Tubes, does anyone know where I can get cheap GrooveTubes? I
have a Digitech TwinTube preamp and one (maybe both) of the tubes have
blown. Pref in UK...

I have been working on a 'simple sampleplayer' that acts as an ALSA sequencer
