About this app

Yo, Bass drummers! Got a split in your head that you've just got to hear right now? Got a line or a lick or an exercise to put down? Compose it and play along with the new Bass Line Composer App!

Now you’ve got a whole bass drum line to play along with. Practice splits and interp. Write out your exercises or make up new ones. Put down that new street beat that’s been bouncing around your brain. Speed it up, slow it down, try it out, edit it, and max it out!

Compose and play along with the actual bass drum sounds of the Paul Rennick 2012 Santa Clara Vanguard, as recorded by bass tech Brian Lowe - tuned the way they’ll sound on finals night.

Version 26.06.18 · 2026-06-18
What’s New In Bass Line Composer The app has been rebuilt around a faster, more reliable writing and playback experience for marching bass line composers. Recent updates improve audio stability, notation flexibility, MusicXML export accuracy, document handling, and the overall editor workflow. Native Playback Engine Playback now uses a more robust native audio path designed for tighter timing, smoother start/stop behavior, and better reliability during rapid playback changes. Practice mode volume balancing, section muting, and loop playback have all been refined to make rehearsing individual parts feel more natural. Practice Mode Practice Mode lets you spotlight one section or bass drum…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
