Fairly new Axe user here. Just finished setting up the MFC-101. First, the MFC-101 is a delight to program. Coming from a Voodoo Lab GCP (and Eleven rack, a couple of years ago) the MFC-101 is almost 'toy-like' to set up compared to the GCP. Couldn't be any more happy.
So, for now, but pretty sure it will change as my needs keeps changing...
