Digital Mixers (w/built in interfaces)

I'm old school. I almost always have owned some sort of vestax or rane analog mixer. DVS came out and ever since the ttm-57 I feel as if mixer quality has tanked

I got to admit I was extremely excited when we could start buying mixers with interfaces built in...so much so I modified my 07pro...off of this dudes inspiration



Now, I don't have the cash to buy the rane 61/62 so I'm stuck with only 2 options:

(1) rane ttm-57sl
- I have actually owned this mixer. Didn't like the layout of it, 16-bit audio, FX, etc...but other then that the mixer was dope...BUT I sold it b/c I didn't want to be stuck with the 16-bit audio interface and wanted to get my cash back on the unit while people still wanted it
(2) NI Kontrol Z2
- I currently own this mixer BUT the main issue I have with this mixer is there are no controls for curve AT ALL for the line faders???? ...sure you can cheat and calibrate them different BUT then you can't do a proper fade in.out transition. You can replace with a PNP but that still doesn't matter b/c the mixer saves the calibration from the software for the line faders and there is no external control knob for the line faders period

So now i'm trying to sell my Z2 and get a 05-pro redbeat or 07-ISP b/c i'm tired of the issues...i'll just modify them with an audio 6 inside like I did my other 2-07pro's that I sold

I just wish that Vestax would work something out with RANE or TRAKTOR like they do with all the new controllers...anyhow, I know that will never happen... just thought I would rant for a moment
