You want Duke to play the guitar? or on a Rhodes? Which type of bass do you need? Drums? Adjust volumes, compression, reverb. Create your own mix of any song and save it. Or mute your instrument to let them know you are in charge of that one.

JAZZ STANDARDS ADD-ON
1300+ Jazz Standards Progressions with Harmonic Analysis, Arrows & Brackets and Chord-Scales.

Ratings and Reviews
See AllNeeds update for M1 macs
Many features are currently broken most importantly there is no sound. Additionally the map itself has no text of chord symbols.
Update 2024: Every year or so I open this thing up to see if it will work. Today I found out the no sound issue was due to some interaction with this software and my audio interface, when using a bluetooth headset it is now working.
With the audio issues and others I initially pointed out working, I’ve moved the rating up to a 4. As an amateur musician, this app is a goldmine for thinking in functional harmony and a very interesting concept. I believe this app could actually be a lot bigger if the UX execution and features were rethought. This is primarily a play along app for Jazz musicians but I think it could be an even better tool for composers, especially if other types of harmony were introduced such as riemannian harmony and other forms of non functional harmony.

An absolute work of genius
This is, without a doubt, the most incredible musical training software/musical software period, that I've ever used (and I've been around long enough to have seen Led Zeppelin on their second tour of the US). Yeah, you have to put in some work, and no, the UI is not at easy as taking a selfie (which is gonna scare away most americans anyway) but the app enables you to explore and experiement, and tells you what works and what doesn't. Musical theory is no longer theory - it's sounds, sounds that evoke emotion, and this app, if you take the time to learn it, will teach you how to replicate those sounds.
I have all of MDeck's apps and a lot of their books, and I'm not even a jazz dude (stoner/doom metal is me) but running progressions by brilliant musicians through Mdecks and seeing how and why something works, is absolutely incredible. I can spend hours fussing around on this thing. It's an incredible piece of software and if you want to open the world of music, this is the key. Thank you!
Misleading, and some disappointment but overall brilliant
The app has positive qualities, however ultimately there are problems. It’s misleading, because it is not the same as the iPad version. This is an older, outdated version and it seems they are not working to update it. Don’t be fooled. You cannot make long progressions. It is lacking features the iPad version has, such as modulation built in. Worst of all, the MIDI bouncing feature appears to have issues at first (though I resolved those by messing with it and manually making a folder and then manually adding the .mid file extension… still seems silly).
That said this program, otherwise, is absolutely brilliant for teaching harmony. Absolutely brilliant. It’s so good for that that I have to say that I would have given this 1-2 stars for the severity of some of the above problems (IMO) but since it’s so great otherwise, I simply don’t really care that much.
