The Ampero Control is a really small and inexpensive MIDI-controller with excellent build quality and an extremely wide range of capabilities. I'm using it to switch presets and effects in BIAS FX 2 and it works like a dream! Here are the pros and cons:
+ Relatively inexpensive
+ Fairly easy setup, works with basically anything with MIDI
+ Small and light = portable
+ Can send both PC and CC messages via MIDI, to any channel
+ Supports "single", "toggle", "momentary" and "hold" button methods
+ Powered by either USB or regular power
+ Possibility to use additional expression pedals
+ Good companion app that has intuitive and helpful features. Connects very well to the unit.
+ Excellent build quality. Buttons feel solid and they don't make too much noise when used.
+ Up to 100 switchable banks. I use these so that 1 bank = 1 song (because in each song, you probably need max 2-3 different sounds).
Cons:
- Small display only displays numbers, so it's possible to get lost if you have many presets and banks
For me, four buttons is the perfect number because I don't think anyone needs more when playing a singe song. And between songs, you can switch the bank to get another four different functions. So overall, I'm really happy that I got this and it's a permanent addition to my pedal board!
