### 1/5 — WTF

*2026-08-30*

What happened to my playlist?
New format cleared out my playlist. Too much trouble to start over.

### 5/5 — Absolut top Weltklasse!

*2026-08-28*

Kaum zu glauben - die App groovt tatsächlich. Super Soli, Voicings, Dynamik, Phrasierung - alles top! Und der ganze Apparat klingt wie eine Live-Band, obendrein super gemixt, gute Sounds und ausgesucht schöner Ton auf allen Instrumenten. Ich wüßte nicht, wie man so etwas besser machen könnte.

### 5/5 — great update

*2026-08-24*

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

### 5/5 — Excellent

*2026-08-23*

Excellent, just wish these (and the platform) were available 30 years ago ha!  
Sound much better than ireal pro and more contemporaray than the old aebersold tracks, and better value for money then the subscription models
Absolute must have

### 4/5 — That’s what I’m talking about! But needs a few twicks.

*2025-10-11*

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.

### 3/5 — 改善希望

*2025-09-16*

1.カウントインを固定 毎回セットは不便     2.ミキサー機能が欲しい ベース音が小さすぎる ピアノトラックをミュートできるよう(各楽器が分離トラックで録音)

### 5/5 — Superb interface

*2025-03-24*

This app is another amazing addition to the quartet series. One of the most useful features is that tracks are labels as “in the style of”. As a teacher this allows me to accurately pinpoint different styles and then refer students to the original for further inspiration and language. Finally that can return to the tracks, mute the drums and work on the material they have discovered at a range of tempos 👍👍😄

### 5/5 — Top of the heap!

*2025-03-16*

What sets this apart from other playalong apps is that the instruments are recorded ‘live’. It makes such a huge difference and really makes you want to play, unlike the dead sounding midi apps out there.The fact that you can separate the tracks and send them to yourself is an absolute masterstroke too. Don’t even think about it - buy it immediately. It will change the way you practice!

### 5/5 — Another fantastic quartet app

*2025-03-15*

This is the latest instalment of 4 related quartet apps. This Quartet 4 continues with the same high standard of presentation, ease and performances as the previous 3. For anybody that is interested in starting or developing further into improvising and learning new tunes and/or chord changes, this app is fantastic. I use these apps all the time and the quality never fails to impress me.

### 5/5 — Another banger

*2025-03-15*

Please see my review of Quartet 3 - all of what I said in that applies here too. Just to add, I’m a trumpet player and as such it’s very easy to fall back on all the usual technical stuff rather than using practise time to get more creative and learn new tunes. There is a great selection of chord sequences here that I don’t know, and a playlist that allows me to find tracks easily. It’s easy to display transposed chords for Bb Trumpet, and change key for a full “cycle of fifths workout” on a tune. I’ll definitely be using this regularly from now on!
