MIDILODY: Your generative MIDI Sequencer & Looper MIDILODY is a generative MIDI sequencer and looper designed to inspire musicians with evolving, musically rich loops. It excels at creating original sequences that evolve over time, perfect for ambient textures, live performances, or sparking new musical ideas. Key Features: - Evolving Sequences: New notes and rests are added at precise timings, allowing them to overlay existing ones. This overdubbing creates dynamic rhythms and chords, making your loops evolve organically. - Real-Time Editing: Remove unwanted notes and rests on-the-fly without interrupting playback, giving you control during live sessions. - Key and Scale Selection: Choose from predefined scales to set the tonal foundation of your loops. - Auto-Pause Functionality: Automatically pause after adding a new note—ideal for live ambient performances where gradual evolution is key. - Infinite loops: let your MIDI sequence evolve for hours and days constantly. Perfect for ambient / sleep patches. - Rests probability: more flexibility for your loop. - Adjustable Sequence Length: Set your sequence length up to 64 notes - Adjustable Loop Duration: Set your loop duration to 1 bar / 4steps , 2 bars/ 8 steps, or 4 bars/ 16 steps to suit your musical needs. - Velocity and Notes Filtering: Apply filters to capture notes with low velocity, perfect for creating subtle ambient textures. - Note-Off Messaging: Send note-off messages to accommodate external gear or plugins. By default, notes adhere to your AUv3 instruments’ settings. - MIDI Notes routing: filter your notes by octave to send them to other instruments - AUv3 state saving Designed by Musicians, for Musicians We’ve invested significant effort into MIDILODY’s layout and user experience. As daily users ourselves, we’ve ensured it’s straightforward and intuitive, allowing you to focus on creativity. Seamless Integration MIDILODY thrives when paired with MIDI routing options from your AUv3 host, enabling the creation of intricate, evolving textures across multiple AUv3 instruments. Experience the Difference MIDILODY isn’t just easy to use — it’s uniquely inspiring. With every session, it sparks new ideas and unexpected musical directions. Whether you’re producing ambient soundscapes or live looping, it just might become your favorite creative companion. IMPORTANT! MIDILODY is and AUv3 plugin. It won't work in standalone mode. It needs an AUv3 host such as AUM, Drambo, Cubasis, etc.

About

Kaleidoscope Echo

This app processes MIDI messages to create delayed and manipulated note sequences, simulating audio delay effects with added musical control. It allows for pitch and velocity manipulation of repeats, scale-based harmonization, and real-time harmony generation.

Highlights
  • MIDI note delay simulation
  • Pitch and velocity manipulation per repeat
  • Scale-based pitch harmonization
  • Real-time harmony generation
  • Customizable note sequences
  • Preset manager

Kaleidoscope is a MIDI processor designed specifically to simulate audio delay lines, but instead of processing audio data, it generates a series of delayed MIDI messages to achieve the same thing sonically, but with some added advantages. You can have Kaleidoscope emulate multi-tap delays and gating effects, as well as being able to manipulate the pitch and velocity of each repeat, something that is not normally done using a typical audio echo or delay effect. By default, all repeated notes are processed using the chromatic scale mode, but you are free to impose any key and scale to ensure any pitched notes are incremented or decremented in accordance with the chosen scale. Any MIDI notes that are presented to the Input MIDI port are processed by Kaleidoscope, and the modified output is then passed on to other instrument plugins. You can chain multiple instances of Kaleidoscope to create even more complex harmonies. For example, the first instance could turn one note into a simple 3-note chord, and the second instance could add octave offsets to create a lush, multi-octave outputs – all from a single note! It is also possible to perform simple, real-time harmonies using Kaleidoscope by setting the number of repeats to zero. In this mode, you can customize the pitch and velocity settings and add up to 17 additional harmonies. You can also switch to user definable mode to specify per step velocity and pitch settings to create complex sequences, complete with ties, note skip and loop mode. Features: ○ Ability to set a velocity increment or decrement per repeat. ○ Increment or decrement the pitch by a specified number of semitones per repeat. ○ Increment or decrement the pitch by a specified number of scale degrees per repeat. ○ Disable specific repeats to create syncopated rhythms or simulate a tapped delay. ○ You can turn disabled notes into ties. ○ Apply key and scale to the generated notes (126 scales supported in every key). ○ You can create your own custom scales. ○ User mode allows complete control over pitch and velocity per step. ○ Use Kaleidoscope to create instant real-time harmonies. ○ Create your own custom pitch and velocity sequences. ○ Preset Manager to create, load, save, and rename presets. ○ Drag and Drop backups and exports.
