*** Note *** Although mKer can run as a stand-alone app, the recommended way to use it is as an AUv3 plugin from inside a suitable AU Host app that supports MIDI Processors such as AUM, Audiobus, Cubasis etc. Please also note that mKer is a MIDI app/plugin. That means that it does not produce sound itself - it needs to be connected to an audio source that can receive MIDI. mKer is a versatile, multi-output MIDI step sequencer with an extensive range of features. These include: - 8 MIDI outputs - 64 Patterns - 16 Lanes (aka tracks) per Pattern - Independent number of Steps (1-32) and Step Size (1/64-256 beats) per Lane per Pattern - Every step can play either a single note, an interval (2 notes) or a chord (3 or 4 notes) - Lane Step parameters: Play Cycles, Skip Cycles, Play Offset Cycles, Pitch, Velocity, Probability, Offset (can be used for ‘swing’ like effects), Repeat (rachet) and Gate - A flexible Editor that includes a step entry keyboard, parameter sliders and a variety of options and utilities designed for to make the workflow intuitive and fast - 32 Clips with 1-8 Steps per Clip, 1-128 repeats per step (every clip step has one pattern) - 3 Play Modes: Pattern, Clip, Sequence (all Clips) - A Performance tab with 10 fully assignable MIDI sliders, a 12-snapshot bank and morphing function between the snapshots... - MIDI step input and real-time recording - 12-track beat generator with six genres, density, intensity and GM beat mapping ... and more!
MuseBud
This app generates musical notes based on user-defined probabilities for various musical parameters. It includes a looper for capturing and repeating sequences, with detailed editing capabilities for individual notes within the loop. It's a powerful tool for creating complex and evolving musical patterns.
- Generative note creation with customizable probabilities
- Adjustable note, octave, duration, velocity, gate, and ratchet parameters
- Integrated looper with up to 64-note buffer
- Step editing within the looper
- Multiple pattern support with independent looper buffers
- Key and scale customization

MuseBud, a generative MIDI sequencer, creates notes based on the possibilities you define. Customize the chances for every aspect, including notes, octaves, note lengths, velocities, gate lengths, and ratchets. Each mode (note, octave, duration, velocity, gate, ratchet) features its own parameters. Utilize the faders on the main UI to set the likelihood of each parameter being selected by the engine. Easily exclude parameters by assigning them a 0% chance, ensuring they never occur. For quick adjustments, employ the draw mode, 'All 0%' and 'All 100%' buttons on the bottom toolbar. When you press the play button in the standalone app or the AUv3 host app, MuseBud continuously generates notes. The looper records up to 64 notes in its buffer, enabling you to loop back a preferred section in the sequence. Set the start point and step count of the looper in the buffer. Pressing play on the looper stops generating new notes and begins looping the selected section. When you stop the looper, MuseBud resumes generating new notes. Toggle the record button on the looper off to prevent recording new notes into the buffer. Edit steps in the looper by simply tapping the desired step to delete or edit, and choose an action from the popup menu. In the step editor, modify properties assigned by the engine, such as note, duration, octave, velocity, gate length, and ratchet count. Generate various patterns for multiple generative sequences. Each pattern comes with its own looper buffer. When creating a new pattern, it automatically duplicates the current one, ensuring you can craft multiple loops without losing your randomization settings. - In the note mode, you'll have "Rest" (no note) and all the notes in the scale you are working. You can change the key/scale in the settings menu as well as with the BrainBud app. - Octaves could be between -1 and +9. - A note duration could be as long as 4-bars long or 1/64th note long. - Adjust velocity between 0-127. Use the fader grouping button at the bottom to filter faders for faster assignments. - Gate length can range from 0% to 100%. The fader grouping button is also available in gate mode for streamlined adjustments. - Ratchets can be between 1 (no ratchets), 2, 3 or 4 repeats. For optimal results, fine-tune the possibilities and consider excluding a few parameters for added precision. MuseBud is a MIDI app and does not generate sound on its own. To hear its output, route MuseBud's MIDI output to your audio app's MIDI input. The AUv3 plugin app requires an AUv3 host app, such as AUM, Loopy Pro, Logic Pro, Cubasis, Nanostudio, apeMatrix, and more.
