So. Been thinking about buying a Helix Stadium for a while and how I'll integrate it into my rig or my rig into it......
This came as a surprise.



Its very good (modern gear is very good), simple to use, and its tiny considering that its the full QC minus the footswitches (for 75% of the price, and cheaper than a used one in the UK - your taxes and pricing may be different).
The size is perfect for using on a desk, on the floor its easier to use the footswitches properly (bank up/bank down uses left and right pairs), the scenes function works instantly (like Line6 snapshots). However I don't need the footswitches, I have a full on midi control setup with footswitches and exp pedals, and use pc editors almost exclusively so this is perfect.
The i/o is good - midi in/out, usb, inputs, XLR outputs, 4 mono or 2 stereo loops, and capture i/o. I could in theory use this to run my rack instead of the Helix.
Would I ditch the Kemper (or the Helix) ? Nope - I have alot of profiles which I really like (the collection of rack preamp profile I got to stop me buying more rack preamps for instance), and use the Helix as an I/O hub and midi controller for the rest of my collection.
And the sounds - excellent so far. I have pedals, rack FX, Helix, Kemper, and plugins to compare it to. Its very good. YMMV.
