Visual Magic

The Circle Central displays notes clearly and creatively, linking each one to form pleasant patterns that boost creativity and make creating more enjoyable.

Keyboard Mode

You can control it from your MIDI keyboard, activating or deactivating the sequence and transposing it based on the note sent, or use it freely and independently.

Quantized and Free Offset

You control note distances, either quantized for equal timing and direct rhythms or free for total flexibility. You can also combine both methods.

Probability Function

This function enables the creation of dynamic and randomized musical patterns by triggering notes according to a specified probability percentage. A setting of 0% indicates that there is no chance of notes being triggered, while 100% ensures that notes will be triggered with certainty.

MIDI Capture: Capture/Record Sequences in the App

Easily export MIDI sequences with the “MIDI Export Button” to a designated folder, or use “DragDrop MIDI Export” to intuitively drag and drop them into a DAW or desired location for streamlined processing.

Note Collections

It features 57 meticulously chosen note collections to cover a wide range of sounds.

Trigger Bars

The sequencer has 8 points to activate or deactivate. Click the circles around it to toggle a trigger bar, triggering a note when it reaches an activated bar.

Number of Notes

This allows for a wide variety of musical shapes, from simple melodies to complex musical patterns ranging from 2 to 82 notes.

Multi Output

Trigger bars can be mapped and sent through different independent MIDI channels. Additionally, each trigger bar can be selected independently for its octave.

MIDI Learn

Many parameters in Harmony Bloom can be controlled using MIDI CC. Right-click on a parameter, select “LEARN MIDI ASSIGNMENT,” and control your parameters from an external controller.

Speed Offset

controls the timing between notes: for values from 0.0 to 1.0, notes progressively speed up from the center outward; for values between 0.0 and -1.0, notes slow down from the center outward.

Random Velocity Generator

Velocity Range Controller with V.MIN and V.MAX for setting minimum and maximum note velocities, and a Randomize Velocity button for dynamic, human-like velocity variation within defined limits.

Random Advanced Controls

It has a Global Random button that randomizes all (controls can be excluded), creating new states with each press. Each control also has its own random button for quick, surprising changes.

Compatible with any DAW

It works with most DAWs that support VST3 and AU formats, such as Ableton, Logic, Bitwig, Cubase, Reaper, FL Studio, and Studio One.

Scale and Root

Offers 57 musical scales or modes, ensuring notes fit the selected scale for consistent melody and harmony in your music.

Sync DAW Tempo or Not.

It can sync with your DAW bpm or not, ensuring what you generate always fits your project.

Create, Edit and Share Presets

Presets can be easily saved and shared with other users as files.
