## What is PolyBud Polyrhythmic Sequencer?

PolyBud is a multitrack polyrhythmic AUv3 MIDI sequencer. You can add multiple note or MIDI CC tracks to the each pattern. The note tracks has the note, velocity, gate, ratchet, probability and randomisation modes. You can set different step lengths to the each mode which would introduce polyrhythmic variations immediately. 

Another great feature is the each track can run in a different rate which is great for creating unique polyrhythmic sequences. Also, you can assign different MIDI channels to the each track so that you can control multiple synths within a single PolyBud pattern. 

The MIDI CC tracks is great for modulating the synth parameters. You can introduce polyrhythmic modulations by setting the different step lengths and different rates to your MIDI CC tracks. Also, you can set a ramp value for smoothing up the CC value changes per step. If you set the ramp value to 0% then you can have the classic sample and hold modulation. 

PolyBud is a MIDI app and it don't produce any sound of its own. You need to route PolyBud's MIDI out to your audio apps in order to run PolyBud. For the AUv3 plugin, you need an AUv3 host app such as AUM, Cubase, NanoStudio, ZenBeats, BeatMaker, apeMatrix etc.

### 5/5 — Bought. Understood. Wrote music unlike anything I’d done before.

*2025-09-06*

I can’t think or imagine polyrhythmic music. I like 4/4. I bought this to challenge myself. An hour in and I think I’m Radiohead reincarnated. Wrote something that kept evolving and it tickled my brain. Very happy with my purchase.

### 5/5 — Stellar App and Developer

*2025-08-05*

a great quick little multitrack (i.e. poly) melody sequencer. each track can have a different rate/tempo. and this works for modulation eg u can sequence cc midi messages between different instances of polybud in AUM or to other auv3 apps. stellar developer here !!

### 4/5 — Good but there is one annoying problem.

*2022-06-10*

I’ve got almost all of the Bud apps and they’re very useful, but there is one problem with all of the ones I’ve tried. Adjusting the play rate is difficult and sometimes just impossible to do.  The wheel jumps rather than scrolls and I was trying to use PolyBud with iSymphonic. I wanted to adjust the speed from 1/8 to 1/4 as I was using some strings and wanted to slow them down, but I just couldn’t do it. The wheel is very jerky and jumped between 1/2 and 1/32. 

After fiddling with it for nearly half an hour and getting nowhere I just abandoned the project. This problem is present in other Bud apps as well, and I had hoped that it would have been fixed by now. Perhaps everyone else works in 1/8, 1/16 1/32 and even 1/64. I’ve found I can select these speeds relatively easily. Am I unique?
