I only need one for the gp10 and I have them both. Perhaps when I decide to grab the helix these can help me out.
Thanks for the good news on the rack units.
what appeals to me is getting the rack and then the separate controller since you can use the external 3 controllers on the foot controller plus the 3 on the helix rack and that makes6 usable controllers so that opens the door for some interesting strategies mixing tones, various guitars using a GP10 and a variax and all the FX in the units and even from additional pedals and units you hook up in the 4 effects loops.
I will be interested in the vst version first to evaluate it but even if it is weak in a single area I figure it might have enough to warrant buying the rack and controller since you can then use it as a hub for all your rack effects and that plus the variax interaction will make it a must.
