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 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 not an audio app that generate sound. For the AUv3 plugin, you need a host app such as AUM, Cubasis, apeMatrix, Nanostudio, Beat Maker etc.

What’s New

Version 2.2

This version adds the new Manual Trigger mode.
- When activated, the sequencer will only advance when a MIDI note message is received.
- You can toggle quantization for manually triggered notes.
- The "Hold Note" option plays the note until a MIDI note is triggered, overriding the sequencer's internal rate and gate settings.
- Also adds the new Gate and Gate Variety options.
- The min/max velocity and randomise velocity options removed with the new Velocity Variety option.
- Updates the AU parameters with the new ones.

Very Interesting…

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…
