I use FIT with MixingStation.app w. touchscreen and M32C and really like it, basicly LV1 (i have Waves SR Performer too). Build quality is solid for money, feel is good. What can be better- VU indicators, even "signal present" would be enough; faders end values are poorly encoded (e.g. minus ininity is hard to get etc). As a comparison, X Touch is much better in this part!
Really like layout for live mixing! But, in my opinion, FIT lacking a bit if used with DAW, especially compared with X Touch in dual mode with M32.
