Hey there, lot of of people with the same issue...
so I tried Bitwig Studio, after I had to accept that its impossible to work with studio one 2.6.
Appart from less cpu usage by the daw itself, I've noticed a shorter delay, after open spark 2 -(3 to 10 seonds).
Also it sandboxes every single vst's and not only therefore, it is the daw I'm going to head.
ableton also works kindly, but I've had some diffrent bugs.
If Bitwig Studio or Cubase 5 wont make me happy, I definately will go back for ver. 1.7, till Arturia will release a Cpu friendly Version.
Otherwise I have to buy a silly expensive "DIGITAL SIGNAL PROCESSOR"...well in that case I could have bought a hole bunch of analog gear....
so all my last hope is Arturias moral now...
no no no: Music lovers of the Arturia IT department: I AM SURE YOU WILL MAKE IT!
