User Reviews

Users praise Bass Line Composer as a powerful, versatile mobile tool for composing bass lines and drumline parts, with a wide sound library and features suitable for teaching and practice. However, recurring issues dampen experience: frequent crashes and data loss, regression in sound quality after updates (including muffled drums and metronome quirks), lack of an undo tool, and awkward file management. The app remains highly valued for its capabilities and ongoing development, but reliability and usability concerns are frequent bottlenecks for many users.
Pros
  • Versatile, feature-rich bass line and drumline composer for iOS with complex rhythms, tempo changes, and playback on a phone.
  • Extensive, high-quality sound library and effects that support varied, realistic drum sounds.
  • Strong teaching and practice utility; helpful for instructors and students to learn parts before playing.
  • Intuitive interface and ongoing updates that expand capabilities while keeping it usable.
Cons
  • Frequent crashes and data loss: saved work can disappear, files become inaccessible, or the app crashes on launch or save.
  • Sound quality regresses after updates: muffled hits, worse sounds, and metronome/volume controls behaving oddly.
  • No undo button, making mistakes hard to fix and forcing manual deletions or edits.
  • Clunky file management and navigation: saving/naming is not straightforward, files can be hard to locate, and updates can wipe or reset work.

This, as well as the Ensemble composer app, were my favorite for transcribing and testing out ideas. Unfortunately none of my existing works plays correctly, as the sound lags and has weird spacing no matter what tempo I chose. Also, the new sound effects replacing some of the existing sounds, such as the snare drum shot, ping, and stick click are much worse (the stick click especially; sounds very clunky). The stick sound effect for the metronome has also been replaced with a worse, clunky sound as well; not really sure why they replaced that sound when the new one sounds nothing like any sticks drumline techs would use. Very disappointing with this latest update.

This has been hands down my favorite app to use as a bass drummer. Since 2020 when I got it, learning to use it and fully understand how everything works has been one of the most rewarding experiences ever. Being able to compose entire scores from my phone is a very powerful tool, however this new update is making it very hard to use. The sounds changing has been probably the worst part of the new update, but the Metronome not changing volume or staying as whatever I set it to is a close second. These micro details make it so hard to use, especially being used to how it was before. This app would be a genuine Top 3 app of all time for me if these issues got fixed.

I’ve loved this app for a long time. Although in this new update, the bass drum sounds have a muffled popping sound like a static pop after each hit, making it just so annoying to compose and listen to (causing it to no longer be fun to use). Before this update, the sounds were amazing and so satisfying. Also the buttons, like flam, buzz, rim click, etc. are smaller now and harder to press. It just got an update after years but still no undo button! Please add an undo button! Also the met sound doesn’t get quieter when i turn the slider down and it’s so loud. Also, the met that I set it to (stick click) no longer stays selected after I close the app, which is also a bit annoying because it used to stay. Also, I might be going crazy but I do think the stick click met got changed, so it would be cool to be able to customize the kind of met a little more, because I really liked the stick clicks before the update. The most important thing for me is the sound of the bass drums and the static pop is really annoying, so if there’s any way to fix it, that would be really cool! The app in general was just much better and more practical before update 2.5.3. Amazing app though!!
