The patch exposed the internal mixer matrix as normal ALSA mixer controls. It is in mainline kernel since some 3.x version, I don't remember exactly which. So you can use the mixer matrix with any alsamixer app. I use qasmixer, which handles the high number of controls better than other UIs. Next time I am in the audio room, I want to try AlsaJsonMixer, which has a specific UI for the Scarlett: https://github.com/fulup-bzh/AlsaJsonMixer One thing that isn't exposed in the mainline kernel anymore is the "save state to hardware" feature, which allows the device to be used stand-alone, without a computer. But it seems to store the last values anyway - maybe the values are saved by default by the driver at some point, I'm not sure. > >I have managed to run it with JACK at 64 samples, 2 buffers @ 44100 Hz, > >with an RT patched 4.x kernel.

I lugged it around to a rehearsal room and to a few performances. It has a solid thick aluminium case which is very rugged - I could probably stand on it without problems. :) The plastic knobs are OK. I've recently noticed some scratching noises on one of the pots. I hope it can be replaced. > I ogled with the soundcraft signature series (no ADAT and no MIDI, but > a mixing console), but fear durability issues. > > FWIW in parallel I ask for iPad 2 compatibility at > http://www.xewton.com/musicstudio/forum/viewtopic.php?f=4&t=7498 . I don't have an iPad so I don't know. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
