Highlights
  • Random looping generative MIDI sequencing
  • 16-bit shift register logic
  • Adjustable chaos for sequence variation
  • Over 110 scales plus custom scales
  • MIDI CC generation and modulation
  • Unlimited pattern pages
  • Manual trigger function

Read full description

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.

'sinusedo' is a sinewave synthesizer in standalone and AUv3 formats. It features two independent keyboards with: • 4 – 72 keys (voices, steps) per octave, each with its own ring modulator • maximum polyphony equal to the number of voices; max polyphony is 144 voices • 1 – 4 octave range, covering the frequency range of about 8 – 4200 Hz • display with note number (from C), note name, frequency (in Hz), and deviation from 12-TET (in cents) • two sections per keyboard: upper for non-sustained notes, gliding, and velocity; lower for sustained notes and modulation rate • mute button to stop/start all sound • delete/panic button to erase all notes • glide button for smooth sweeps across keyboard frequency range • modulation on/off button • slider to set initial velocity and modulation levels • slider to change velocity and modulation rates for all notes on the keyboard proportionally and to show current velocity and mod rate levels • button to toggle keyboard visibility. sinusedo supports MIDI input from external sources to control each keyboard independently. Supported devices: iPad, iPhone
