Screwup

Paul , you screwed this up totally. It was much better than all the other apps.
The new format stinks . Why do people always think they have to make something better. It was great before.So much more difficult to read the chord charts now.
What a shame.
Maybe someone else will fix your,
Oh never mind. Y’all just jumped the shark!

great update

great update. Many thx for that. Good job and excellent musicians playing.

Best in class

Great series of apps, affordable no subscription, and real perfomances, albeit straightahead, so perfect for learning standards, but also viable backing tracks

Keys?

What am I missing? Why does it seem the keys chosen for 3 and 4 are not the common keys used in fake books? They are so far away that when I adjust the key, the track is distorted. You really can only adjust so far up or down before the track sounds crazy. A real disappointment. 1 and 2 are stellar!

Yeah me likes but…

As I say in the title, this is a very nice sounding app. The recordings are very nice, but it could use some improvement so here’s my wish list:
1. Add a tap tempo button.
2. It would be nice to be able to make your own charts and have the band follow in different styles.
3. Not all recordings are super nice. Most of them are, but for example, Fly me to the Moon the drums are horrible.
4. There is no mixer to play with the levels of the instruments. It would be nice to have a mixer.
5. You can only export the file to M4A format it would be nice if you could export to WAV file and MP3 which are more commonly used.
6. It would also be nice if you could export the chord chart as a normal chart or have a choice to view the chords in different ways normal chart or the default way.
7. You have a choice of having the Quartet playing, having Bass and Piano or bass and Drums, but there is no way to just have Drumms only Adding a mixer with alleviate this.
8. The endings have no turn around like a lot of standards do so they end abruptly and well… it be nice if we had the choice.
9. There is no intuitive way to play your personal playlists, you have to click the Edit graphic to be able to see the list you created also as you make your list it’s displayed backwards the first file you add will show up last and the last file you make will show up first. There is a way to rearrange the list but that’s an extra unnecessary step.
10. A lot of the swing files are really fast though they sound nice that speed may not be what the audience is familiar with for example A Foggy Day is recorded at 200 bpm when the most famous recording is around 150 bpm that’s a lot of difference maybe they should have two versions of the song the one they want and the bpm tempo of the one that’s the most famous recording. Like they have two versions of Autumn Leaves.

As for bouncing:
You can bounce to stems for an extra fee or 99¢ per song, it should really be for free I mean the bundle is almost $40 and each separate is $15 a lot of music apps allow stems for free.
All in all I really like it and I recommend it but hopefully they will be developing and adding these much needed features for free.
