## What is ShiftBud Generative MIDI AUv3?

ShiftBud is a random looping generative MIDI sequencer based on the eurorack module Turing Machine by Tom Whitwell. 

It works based on the 16-bit shift register chips where it shifts its value on each sequencer step. However, you can lock the sequence in a desired length if you fully rotate the chaos knob to the left or right. If you introduce low amount of chaos, then the sequence "flips" occasionally and generate beautiful sequences. You can also produce random values if set higher amount of chaos. 

The MIDI note generation can be in more than 110 scales plus your custom ScaleBud 2 scales. You can set the octave range, velocity or velocity randomness as well. 

You can set the higher and lower bounds on MIDI Control Change generation as well as the CC number you want to control. It's very useful on modulating synth parameters and you can even modulate the ShiftBud's AU parameters as well. You can also set a ramping value for a smoother change. With the 0% ramping, you can use it like a "sample and hold" module. 

With the manual trigger function, you can use another sequencer or keyboard to trigger ShiftBud's next note. 

You can create unlimited pattern pages on the lower left corner of the app and you can select the pattern with MIDI CC messages as well. 

Please note that ShiftBud is a MIDI app. The standalone version has an optional internal synth where you can enable or disable on the settings menu. The AUv3 plugin requires an audio app for output. For the AUv3 functionality, it needs to be hosted within an app such as AUM, Loopy Pro, Cubasis, Logic Pro, Nanostudio, Drambo, or apeMatrix.

### 5/5 — No more MiRack for my AUM sessions

*2025-08-03*

I often used a MiRack instance (and all its overhead) just to use the Turing machine module. This app replaces all that mess and really fits in with AUM’s modular layout. A must for fans of generative sequencing.

### 3/5 — very simple

*2022-05-02*

…

### 5/5 — Very Interesting…

*2022-04-17*

Another nice pattern generator, with a twist… sounds like not just random notes within a scale. Could have some interesting uses.
It would be nice if Cem would also include probability, and randomization of gate length and other parameters in future updates; these are present in MelodyBud, and they really add to the unpredictability…
