I’m very close to pulling the trigger on an A4 MK2 (just selling some unused guitar pedals to fund it).
I’ve never used gear with multiple outs and I’m wondering how useful this would be with an iPad?
I have the Liven L6 mixer/audio interface and an iPad pro. I could definitely have 4 tracks running on individual channels in AUM.
Are there any good recommendations for FX apps that would work well in this scenario?
Eventide has a bunch of effects, including Blackhole, on iPad.
There’s also this, which I haven’t bought yet but looks good: https://busycircuits.com/mfx-motto/
And one day soon we’ll hopefully have Overbridge for iPad 
that brings your A4 into another category, its cheap and can be your tonverk alternative, love that layout tho
