Sliver is a powerful tool for soundscape and sonic texture creation. Working beautifully with any audio content... melodic, rhythmic, noise, or otherwise, Sliver is well suited for a broad range of project types including: Soundscapes Ambient Drone Glitch Noise Pads Sound Design / Sound Effects Unique Sonic Textures Cinematic Sound Elements Creating a playable instrument from any sound. The core of Sliver is the 4 real-time resizable clips (slivers) that can be moved around the waveform. Each sliver has it’s own channel with independent volume, pan, filter, and sliver size. These controls can be set in motion with Sliver's automation engine. Sliver uses a real-time automation system to movement in your textures. This system also allows for override to be able to shape the ongoing captured performance. The filters and size windows are controlled by XY pads, giving Sliver a natural playability, creating a new type of instrument. Touching along the waveform places, moves, and sizes the slivers, allowing you to intuitively scrub the waveform with a variable loop size. A chain of effects assigned to XY Control pads allows you to shape and mangle the sounds produced by the slivers. You can Automate every control. Sliver uses Apples UIKit Dynamics to create physics on the XY Pads, allowing customized settings for the controls to shape the sound randomly with physics. Sliver supports Audiobus, sitting in an input slot. You can import samples via AudioShare import or Audiocopy. You can resample, record your own samples via the Mic, or do both at once. This app uses Background Audio and Records from the Mic. You will see a red bar when placing the app in the background. Sliver supports MIDI learn and is fully controllable from Virtual, Network, and MIDI hardware. Make some noises, mangle some sounds, create your own soundscape.

This app generates random MIDI sequences using a shift register chip, inspired by a popular eurorack module. It offers extensive control over scales, octaves, velocity, and MIDI CC modulation, allowing for complex and evolving musical patterns.

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.
