I'm looking to get some synthy sounds from my guitar and it seems like the Slim Phatty may be a good option for me. It's got the basic settings that I need (filter, 2 oscillators, CV inputs). I was wondering if I could just use a 1/4" jack from my guitar into the Audio In or if it would be wise to invest in a MIDI converter. I'm hoping to play some chords as well as single note runs (which rules out the Sonuus) and I've heard some good things about the Axon, aside from the latency. Thanks!
