Hey, folks -- as some of you might know, I tinker with writing music apps in my spare time (which I think I do better than writing actual music). I've got a new app that's in open beta for iOS. It does automatic pitch-to-MIDI from a guitar, transcribing whatever you play into tablature -- and it can play the tab back as MIDI notes.
If you've got an iOS device, and want to give it a spin, here's a link that you can use. I'll be fixing bugs and tweaking the UI for the next week or three, and then hope to have it out in the App Store. I've had a FAWMers Fly Free program since the start -- once it's real in the app store, if you want a copy, drop me a note and I can hook you up.
