We recently ran a poll on Studio One Expert to see what interfaces people use with their DAW, on that one PreSonus were the clear winner, perhaps because many people got their software as part of a hardware bundle.
It's highly likely that this will be the case with Pro Tools users too, with many HD/HDX users tied to Avid/Digidesign hardware and until version 9 all native systems shipping with Avid/Digidesign hardware. However it's been several years since Pro Tools native was decoupled from the hardware so Pro Tools users are free to use the hardware they want.
So take our poll and let's see what interfaces are getting the love, there's an 'Other' option for the ones not on the list as well as a distinction for Pro Tools HD and native users when choosing Avid/Digidesign hardware.
Are you happy with you current hardware and would you recommend it to someone else?
As ever please feel free to leave your comments.
