Already mentioned it in another thread and this might be redundant if you own X1, but, if your still using 8.5 or are a GAS victim like me... I've been testing this cool channel strip by DNR.
The layout is terrific IMHO - it almost takes my entire MacBook display, but it's totally worth it. There's also a smaller version for those who prefer that. Makes sculpting sounds a joy.
Pretty flexible, sounds good, and the spectrum display is handy. Not too sure about the saturation though, but I'm usually not a big fan of saturation in such devices.
Oh yeah, and it's not too pricey.
