Hybrid reverb with an artificial space designer, combining it with algorithmic reflections tail processing, is ideal to creating immersive ambience of deep spaces, lush atmospheric textures or stunning whispering backgrounds in your ambient, electronic, experimental and sound design projects. Unlike traditional algorithmic reverbs, Stellarvox constructs a complex model of a vast resonant sound spaces with choice of geometry, dimensions and tonal structure of the space, along with a unique feature that dynamically change the timbre of reflections over the reverberation time. The second algorithmic reverb allows you to prolong and blur reflections, adding extra dimensions to the sound space. Easy-to-use controls on a single screen, along with optimally designed parameters that always give great results, make insignificant the peculiarity of that kind of reverbs, when the model creates with a little delay after changing it. Factory presets and the random feature will give you a starting point of inspiration and allow you to get a quick result where you need just to slightly tweak the parameters to align with your idea. This application is great for ambient projects, it can create mesmerizing atmosphere from single infrequent sounds of various instruments, or giving a beautiful and deep backgrounds to sharp sequences in electronics, as well as for any experimental projects that require unusual, deep and rich sound ambience. Stellarvox is a universal application for iOS and macOS. It can work on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). Stellarvox works on iPhone and iPad standalone, as an Audio Unit or Inter-App Audio module, with supports Audiobus host app. On MacOS, Stellarvox can works both as a standalone application and as an Audio unit (AUv3) with DAWs and other hosts that support AUv3 plugins. All application features are available on iOS and macOS, including MIDI support (with a MIDI learn option) and audio unit parameters. Stellarvox has a built-in detailed description of all parameters also available as PDF file on the application site.

About

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.

Highlights
  • 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.
