User reviews

If only buttons were bigger

Please make the buttons on the app bigger. I always end up pressing the wrong button because they are too small and bunched up together. Is there a metronome here?
Musically however the app is excellent and I highly recommend it.

I don’t recommend

I have all the session band apps, but I don't recommend this one, the musicians who perform are good, but not perfect and their compositions need to be fixed and this app doesn't allow it, the worst part is, with this latest update they have increased the price . I don't recommend it.

Can really recommend …

Quartet 1 was recommended to me and, having tried it out for a couple of weeks now, I can really recommend this app to anyone who wants to improve their playing of the jazz classics or for live work. There are a whopping 150 standards in this app, so plenty to choose from! As a pianist, I like the playlist function, this will be useful for grouping certain songs together depending on the venue/audience/mood. A few of my favourites aren’t in this app, but hopefully they will be in a future release. Quartet 2?

From a seasoned player - this is a ripoff

Cons overweight the Pros:
1. No control of number of loops - as is, the samples are just that: very short samples
2. Tempo is modified by continuously tapping a + or - !
3. No means to modify chord progression
4. Zero help (but we're gonna)
5. Interface is lacking access to the simplest tasks expected by an average user - what a disappointment

Pros:
Nice sounding samples
You can change key
You can change tempo (if you have carpal tunnel)

Not for creative juices.

Sounds good though. As a songwriter/producer this is not what I expected. Would be great if the session band apps the same GUI.
