Hi, I have been using Tonestack3 for a while now, mainly your cabinets and effects through IAA along with BIAS FX. Your midi implementation is awesome and is far better than any of the other IOS guitar apps.
The reason why I use BIAS FX is that it has much better amps and overdrive/distortion sounds. I use your cabs, ABY mixers, reverb, delays, chorus, Wah pedals, etc... all with external midi controllers.
Do you have any improvement/upgrade plans? (Specially amps and overdrive/distortion pedals)
