Best Songwriting Tool I’ve Ever Used

I’ve been writing metal and acoustic music for over 10 years now, and having been in many different projects and seeing my material scattered to the wind, this app has allowed me to consolidate my creative process and I’ve finished more songs in the last year than in the rest of my career, combined.

Now I have a full length’s worth of material, guitar, bass, drums, all finished and ready for any future bandmates to practice in-app. The addition of the 7-string was a HUGE game changer and the best thing they could have done.

If y’all aren’t already working on it, an eight string addition would be incredible, but if not, I will still use this app until the day I die. Congratulations, guys, this is the best money I’ve ever spent!

Developer Response ,

Thanks for the kind review! Actually, 8 string guitar is already possible inside the app! It is only available for 'inter-app audio' or 'midi' instruments as Jam Maestro does not have the samples to cover a tuning range that far, a limitation not present for midi notes. To access 8 string guitar you need to add a new IAA or Midi instrument (pointing at a background app that has guitar sounds, for example Thumbjam is pretty good). If you click 'edit' on the instrument on the main screen you can scroll down and set a custom tuning for that instrument, here you will have the option to set it to an 8 string guitar. Hope this helps!

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!

Developer Response ,

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!).

I like this app a lot

The interface is a bit clunky; it could be less busy and basically a bit cooler looking. As such, it is a bit intimidating to use. You look at the screen and its kind of overwhelming. But, its pretty easy to use once you get started and its definitely the kind of app that the more you spend time with it the better. I wish it was a bit easier to see how to Print and Share. The export function is a bit hard to figure out. Like what if I want to email the text or the PDF to someone? But I am glad I got it, and it is going to help me a lot in working on a song with a friend. Once the tab is in for the song we can play around with you we want the notes to be played. I tried to hand write out the tab and it was a nightmare so I am very glad I found this app.
