My main motivation was that with the ALSA and Jack backends, as far as I
know, you can't have two instances of stk applications running, or any
program using the soundcard and an stk application.
For example, if you run two instances of projects/examples/crtsine, you get:
RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,0), Device or
RtApiAlsa::probeDeviceOpen: pcm device (hw:0,0) won't open for output.
In other frameworks (for example GStreamer's ALSA and Jack plugins), this is
not the case. It could just be a simple matter of improving RtApiAlsa and
RtApiJack, rather than implementing a whole other backend. I think this
would enhance Stk's overall usability tremendously.
