Comment 21 for bug 970965

Hey Daniel!

> I am just wandering if it is possible to configure the VMS2 for 1a?

Not entirely. There is a modus in which the equalizer knobs can be deactivated (they call the two modi "pre EQ" and "post EQ"). There is however no documented way to let the faders only emit a MIDI signal, they seem to be always active.

I am using Linux (Ubuntu 14.04).

I have tried that, it indeed works great in the sense that I did not observe any issue during hours of tests :)

> What is your experience?

My current experience is quite good. I am now using three sound devices at the same time (feels a bit like an overkill by I think I need all of them):
- master -> Behringer USB audio -> amplifier/PA
- headphones -> internal sound device (so that cuing *and* the preview deck work)
- deck A -> VMS2, channels 1+2
- deck B -> VMS2, channels 3+4

In summary, the VMS2 in this setup is only for MIDI signal emission and for VU meter monitoring. Indeed, I am sending the audio to the VMS2 via deckA/B setting *only* in order to be able to use the nice VU meter.

With three sound devices in use and a "normal" mixing performance I produces a 15-minute system load average of 0.7 on a machine with two CPU cores, i.e. while this is a significant CPU load, this is still far from critical (that is a notebook from 2009, with an Intel 2.66 GHz P8800).
