On the bright side for computer based side, steinberg released a asio4all multi access driver
Asio4all, is a pc sound driver co oatible with most all sound devices that makes sure that there is a really low lattency (time between oushing a key and hearing the sound) on PC soundhardware.... On the downside, you could only connect one software package at a time to the sound device....
This is what kept me from buying Varranger so far, because on my DAW, i use ableton for composing and sequencing, and also BiaBox. BiaBox is connected trough Ableton over rewire, Varranger however does not support rewire...
I would be happy if someone could test Varranger with this multiclient Asio4all driver from steinberg...
