Vielen Dank! 🫶🏻 ### 2/5 — Gute Idee, leider so nicht brauchbar *2019-11-01, version 1.0.0* Die vom Algorithmus „komponierten“ Songs klingen leider so furchtbar, dass sie als Playalong völlig ungeeignet sind! Die Akkorde müssten schon halbwegs nach den Regeln und Hörgewohnheiten eines Jazzstandards „sortiert“ sein, so kann man dazu weder solieren noch eine Begleitung spielen. Die „Melodien“ klingen entsprechend schrecklich und unmusikalisch... Zudem fehlen Standardformen (32 Takte AABA) und verschiedene Rhythmen, ein einziger Swingrhythmus wird sehr schnell langweilig. Gut, hat nix gekostet, also ohne Schmerzen gleich wieder gelöscht! ### 5/5 — Very good jazz music *2019-05-12* By using this app, I create my own music very easily and decent quality of music. Thank you. ### 5/5 — Tolle App! *2019-01-17, version 1.0.0* Super schöne Jazz Combos! Wenn man die generierten Stücke noch speichern und exportieren könnte, wäre perfekt 🙂 ### 5/5 — Genial *2017-04-16, version 1.0.0* Super, vielen Dank für diese App! Export als Midi würde ich auch für eine super Idee finden. ### 5/5 — Genial einfach *2017-02-23, version 1.0.0* Für umsonst? Fast schon peinlich dass hier niemand bewertet hat. Einfach genial und klingt auch noch wirklich authentisch. Mir fehlt noch die AABA Songform und die Möglichkeit zu speichern oder als Pdf/midi/mp3 zu exportieren. Zumindest als pdf wäre super. ### 3/5 — Intriguing idea *2016-10-09* This is a most intriguing "little" app with a surprisingly okay soundset. Beware - don't click the play button before you tweak the settings as the "stop" function appears to be missing - so you have to force terminate to halt the demo. As I'm not a virtuoso jazz player I'd find this immensely useful if I had the option to select some/all chords generated in the key - and then build my skill. Otherwise if you're up for it, it does generate a solid challenge. Great concept, hope the developer keeps going. ### 5/5 — CAN stop playback *2016-10-08* Good app, too bad there is no support. Playback CAN be stopped by touching any chord! Some changes are very nice, some not. Fun to practice soloing. ### 1/5 — Cannot stop or pause playback!! *2015-06-05* I have to terminate the application to get it to stop playing. Not recommended!!! ### 5/5 — Great app *2015-03-03* This is a great app to practice with. I play sax and with this app I practice in all keys. Great chord changes too ## Frequently asked questions about Combo ### What instruments can I use with Combo? Combo offers four instruments.
