Close to perfect


There are lots of options and good sound quality. This is an effective and versatile tool for getting your ideas onto some sort of canvas.
Cons: steep learning curve, unintuitive interface, .gpx import is not supported. Seven string tabs unsupported. Lowest tuning supported is drop A#, but the app won't let you open tabs tuned lower than that. It should just automatically set the tab to drop A# if the tuning is too low rather than not display the tab at all.

To respond to dev response: it's not that I want to see lower tunings possible in your app (drop A# is low enough for me), but rather I would like to see tab files already tuned lower be automatically formatted to A# so I can actually view them. Currently, such tabs cannot be opened. I'm aware that gpx can be easily converted to gp5, but most tabs from UG for example are gpx, which means I cannot simply grab them using Safari and view them using only my iPad. These are both simple minor inconveniences which hold the app back from perfection. Thanks for the response, I love your app and I look forward to the next update!

Find me a way to understand how to import .gpx and I may consider it :) You can always export gpx files to gp5 before exporting. Criticism about importing lower than drop A# noted. (Seems no matter how low tuning I provide someone always wants lower!).

Feature rich. Wish UI was more intuitive.


Pretty good so far...except I haven’t yet learned how to vary the speed of the notes when I want to play certain notes as 1/4 notes and some as whole or half notes, for example. I also haven’t figured out how to play certain notes sticcato vs letting them ring.

My notes above are not a hard knock on the app because I’m pretty sure there’s a way to do those things or folks would give the app a low rating. However, for as much instructions as they’ve provided, I still wish the learning curve was less steep and the user interface more intuitive.

So far, I’ve found nothing else in the app store that compares well to this. Looking forward to learning more about how to use it.

Hello! Have you tried going through the tutorial? The answers you seek are in there! I tried to animate the tutorial as much as possible because I know people see text and just go next next next, so hopefully its not a complete wall of text at least.

In answer to your question, you need to toggle the 'stop' button in the middle bar of the tab screen (this bar initially says 'copy' 'paste' etc, but you can swipe left on this to reveal further pages of options), then touch the fretboard strum layer to insert a stop signal (*) in the tab on the string you want. Same goes for 'fade' if you want it to fade out rather than stop abruptly. I recommend you watch the video in the videos section called 'advanced tab tips'. It will show you how to do this and more.

Any suggestions on how to make the user interface more intuitive welcome :)



Love this for creating guitar music when I’m on the road and can’t be at my little home studio. It’s incredible, my only complaint would be that I would like to see more tones and effects sometimes soon, maybe a few more distortion tones and some twangy country stuff. Please dev???haha. Love this app.

In response to dev. I have tried but nothing at the surface seems compatible. If you could recommend some compatible inter app audio programs I would appreciate it

Developer Response

Have you tried using inter-app audio to use sound from background apps? Using that you find a guitar sound you prefer from another app and use it inside Jam Maestro. Same goes for inter-app audio effects :)
edit: I highly recommend ThumbJam ... it has some great sounds, you can use up to 8 instruments from it in Jam Maestro at once if you use the JM 'Midi' instruments on different channels, and is an all round very solid app.
