It takes a little time to get used to the GUI - but if you've used Harmony Bloom then it's all pretty straightforward.
Apart from that, it's pretty much the best chord tool I've used.
Overall, I'll buy anything and everything from Mario Nieto.
I recommend this product

I can't believe it took so long for me to get Chord Generator to partner the excellent Harmony Bloom that I've loved since its release, it's just so perfect a partner. Easy to set up and get really fast and inspiring results. Chord Generator is fantastic for either finding the sound you had in your head and couldn't quite get your fingers to make or discovering the harmonic left turn you never knew you needed. I love this and can see it being part of my template for a long time.

The fact that basically everything is midi learnable is a HUGE positive for my needs. Additionally, Mario has really put a lot of thought and experience into this design. I highly recommend.

I've tried a bun of chord generators and this is definitely my favorite! It hit just the right spot between simple, intuitive, well though out and adaptable. It's so much fun to use, incredibly inspiring and does in fact help to break the mold of what I am used to doing. I also love the chord/preset selection. It feels refreshing and it's obviously chosen by someone with musical taste and feels much more curated and practical, rather than formulaic. Easily my favorite purchase of the whole Black Friday/ Holiday Season!
Chord Generator VST by Mario Nieto
Chord Generator offers a rich chord library, allowing you to select from a wide variety of chord types to suit any genre or mood. With retrigger mode, each pad trigger generates fresh variations, while intuitive navigation ensures smooth exploration of creative possibilities.
Take full control of your harmonies with advanced voicing, strumming, and repetition features. Customize up to six voices, including a bass voice, with options to activate or deactivate components individually. Strum functionality introduces rhythmic depth by applying progressive or randomized delays between notes, creating dynamic and organic textures. The Repeater Option adds even more flexibility, enabling repeated notes at custom intervals for intricate rhythmic patterns. These tools, combined with inversion randomization, voice linking, and locking, offer unparalleled precision.
Expand your harmonic palette with scale and root customization. Choose from 57 scales, randomize the root note for unexpected combinations, and visualize your choices on a keyboard display. The bass voice provides depth and variation, with transposition and retriggering features to evolve your sound further.
Effortlessly capture your creativity with MIDI Capture and Export, allowing seamless recording of MIDI output. Drag and drop sequences directly into your DAW for a streamlined workflow, or use the plugin’s built-in tools for precise adjustments.
The customizable interface includes a color editor, preset management tools, and intuitive navigation. Strum and Repeater settings can sync with your DAW’s tempo or operate in freeform mode, giving you total control over timing and rhythm. Undo/redo functionality and a bypass mode ensure flexibility during production.
