Decent cheap iOS-compatible MIDI controllers?
I'm looking at spending $100-200 USD (new) on a decent travel- or small-sized controller to use with my iPad. I can do either bluetooth or USB, and I'm looking for at least 18 key, 4+ knobs, and something that is nicely compatible with iOS synths and DAWs. Having pads, more knobs, modulation wheel, etc., would all be plusses. Any suggestions you can offer would be fantastic.
