Harmony Bloom (Standalone and AUv3), crafted by Mario Nieto, is a groundbreaking MIDI generator that seamlessly integrates polyrhythmic patterns with stunning visuals. It revolutionizes musical creativity by enabling MIDI data transmission to compatible devices, enhanced by its visual experience.
Distinct from typical MIDI generators, Harmony Bloom offers unique functionalities. The standalone version's ability to generate audio, with five selectable sounds, broadens its usability. It features a comprehensive control set for musical creation, including a Scale Selector with 57 options for melodic consistency, and various offset controls for sequence customization.
The software's visual component, the Sequencer Visualizer, displays intricate patterns of notes, enhancing the creative process. Key features like MIDI Capture and Export simplify the integration of sequences into digital audio workstations, making Harmony Bloom a valuable tool for music production.
Its adaptability is a core strength, with features like 'Use Input Notes' and 'Root Mode' ensuring dynamic musical responses and coherence. 'Global Randomization' allows for exploratory creativity, offering a blend of technical control and artistic freedom.
Harmony Bloom emphasizes user experience, providing intuitive preset management. This focus on accessibility and flexibility makes it an ideal choice for musicians, producers, and composers eager to explore new musical dimensions.
In essence, Harmony Bloom is not just a MIDI generator but a comprehensive tool for musical exploration and creation. Its combination of polyrhythmic generation, visual feedback, and detailed musical control positions it as a standout instrument for creative and professional applications.

What’s New

Version 1.2.8

**NEW: Advanced Quantization Settings:** Control note spacing with quantized adjustments for F.Offset, E.Offset, and G.Offset, ensuring sequences align perfectly with your project grid.

**NEW: individual 'Toggle Random Octave Mode'** : controls for each bar in the sequencer: When activated, this mode enables each note triggered by the bar to be played in a randomly selected octave. This feature allows for intricate pitch variations and adds an element of unpredictability to each segment of your musical compositions.

**NEW: Octave controls by trigger bar** now feature the option to be included within the random octave trigger. For example, we can activate the 0 and 12 options in the octave controls, so whenever we have a random trigger, it will only select either 0 or 12, excluding the rest of the options.

**FIXED**: Improved precision in automation of large values. Previously, some values lost precision due to rounding during automation in a DAW. This fix enhances fine-tuning capabilities, ensuring maximum accuracy when adjusting parameters through automation.

Revised Review

I posted about the AUV3 version not working and also contacted the dev on the support site. The response was positive and immediate.
This app is a very original & creative design and well worth checking out if you’re into generative, ambient type musical ideas.
Kudos to the dev. Great job.

Mario Nieto is a genius! Truly a pleasure to tweak values and let this thing run. The visuals are gorgeous. The fact that you can use it as a midi processor, means that you can use any synth with it. I paired it with BLEASS Alpha and just got back from Jupiter! I know what I’ll be doing all weekend \,,/ Get this app yesterday
