Nice Noel...not a big fan of Jazz, unless it's King Crimson style jazz...is that even jazz? lol
I dabble when I use crazy chords like Gmaj7th#5 and am7flat5th when I'm trying to get back to the home key in my experimental sonata series :), but again is that jazz? lol
Not sure about momentum either?? I've done extensive research on mobile music platforms and tech...and I always found the tech to be to be too underdone to be useful, or in the case of a program like momentum...I just don't have a use for. But I'm a composer, and not really what you would call a songwriting composer these days...I prefer to have Notion (score editor) open and write this way...but I still use Sonar as my DAW, still the best. I hope you guys at Cake haven't bet the shop on Momentum ;). I can see how this app would be useful for gigging musicians and 'real' musos though, particular if the app can access Rode's Iphone mic - do they even still produce that mic? It's been a while, and some of the other phone mics going around...Tascam use to do one off the top of my head. That would be a nice combo, the Tascam phone mic and momentum!
Peace
