BounceBud is a physics based, generative MIDI sequncer. Each side of the app has a customizable keyboard that send a MIDI note when a ball collide with its key. You can specify the ball count, speed and size on the main screen with the knob controls.  In the settings menu, you can set the key/scale, velocity range, octave. range and MIDI channel settings of the keyboards. You can also specify the notes individually per keyboard. All keyboards share the same key/scale that could also be changed with BrainBud. Each keyboard has its own MIDI output, so you can play different audio apps with BounceBud at once. Or you can disable the keyboard sides you don't want to use. With a MIDI input (from a MIDI keyboard or a MIDI sequencer app) you can 'shoot walls' from the keyboards. Balls can interact with the walls and it introduce more randomness to your generative sequence. You can control each keyboard by assigning them different MIDI input channels in the settings menu. You can also toggle the ball collision behavior in the settings menu. Whether balls can collide with each other or not, it creates different, interesting sequences every time. The size variety and ball variety can be change in the ball settings section in the settings menu. It adds randomisation to the size and speed values. You can change the ball color theme in the settings menu as well! BounceBud is a MIDI app and it does not produce any sound on its own. You need to route BounceBud's MIDI outs to your audio app's MIDI input. The AUv3 plugin app needs and AUv3 host app such as AUM, Loopy Pro, Logic Pro, Cubasis, Nanostudio, apeMatrix etc. ## Key features - Physics-based generative MIDI sequencing - Customizable keyboards with MIDI note triggers - Adjustable ball count, speed, and size - Configurable key/scale, velocity, and octave ranges - Individual MIDI output per keyboard - MIDI input for 'shoot walls' interaction - Toggleable ball collision behavior ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/bouncebud-physics-based-midi/id6464171933/reviews.md ### 5/5 — Impressive *2025-08-05* A source of inspiration ### 5/5 — A combination of math and physics that makes melodies *2025-08-02* It’s quite interesting. I use a lot of Cems apps for their melody generators. It’s really cool and by using the parameters at random, you get unique melodies ### 5/5 — Great App! *2025-08-02* Another great and inexpensive app from Cem and yet another innovative way of producing midi! ### 5/5 — great idea wish fl studio/windows was compatible *2025-05-19* i wish there was a way to make stuff from the app and export it as a midi file so that i can use it inside flstudio i bought it with hopes that it can export but was sadly disappointed. great app tho i just wish i had more flexibility and also in app creation of midi files (exportable) to what ever daw u may use ### 5/5 — What have you done!!!, *2024-10-04* I believe, that Cem, will never be able to create such an incredible power house of an app, it’s not an app, This is the divine power!!,!50,00p0 stars would never be even remotely properly represent the the creativity, the legend has pput in to this destruction! ### 5/5 — Fun to use *2024-09-09* This is an amazingly fun app .
