I have 2 "designed for" CW hardware, and both have so many questionable design decisions that I tend to call both "epic fail":
Peavey Studiomix. Nice looking, build like a tank, expensive when released, but:
* what they was drinking while making the decision to send fixed RPNs instead of CC? That creates 4x number of MIDI messages, make the device incompatible with almost anything and also was a reason for trouble with many units (if one message from 4 is corrupted, that produce unpredictable result)
* 2 encoders per strip and... only one button. There is place for more.
* The device is bi-directional (for faders), why could not they put some LEDs?
* it could be used with computer interface and it has a preamp. With one XLR only. No HiZ, no TS connectors, no 6.3 headphone output.
I mean as a unit for home users is was not cheap and not all-in-one. For pro users it had a questionable set of "non-pro" features.
Roland VS-20:
* digital gain with finite knob (saved $0.05 ?)
* hardware effects, but no stand-alone mode and no possibility to control it from the device (the last they could easily do in software)
* USB 1, so 2in2out.
* Rather complicated (software controllable!) routing, without save/recall and only with partial control from the device
* except transport, not really usable as a control surface (in original implementation)
So, they put quite some possibilities into the hardware and so was the price tag. But as with Studiomix, it was not shining in any category. Too expensive as 2x2 USB1, unusable as BOSS guitar processor since no stand-along and far from easy to use software, not a control surface. I mean for the price asked, people could get FR Solo + small guitar processor + Korg Nano. And so get much more functional and easy to use device combination (which is still supported, unlike VS-20).
