DeepGliss Is A FREE Continuous Chord Pitch Bend Plugin


DeepGliss is a FREE and open-source pitch bend plugin for macOS, Windows, and Linux.

DeepGliss is the creation of developer Joshua Postel, and as an alpha release, it comes with a few known issues. More importantly, it’s a taste of an interesting concept and a chance to help the developer iron out any existing bugs (or suggest improvements).

Unfortunately, there seems to be an issue with the macOS download file. I couldn’t install DeepGliss, but hopefully, that’s a quick fix, and I can have another try soon.

DeepGliss allows you to perform continuous pitch bend between chords. You’ll get a pretty good idea of what this plugin does if you listen to the sound demos on the products page. The GUI will give you a more evident taste of what DeepGliss is all about, as you can see each note in the chord drift to its next target.

The thing I liked straight away from the GUI is that the chords weren’t shifting in blocks. You can see that the lowest note can become the highest in the next chord and that internal movement makes it much more interesting.

Continuous pitch bend can be a harsh effect that marks a significant moment in a piece of music or film, usually something tense. It can also be more subtle and musical, which I think could be pretty cool.

Think about divisi violins on a string section; the combination of each violin part creates a bigger picture and some truly epic voicings. How you assign notes to each violin and how each player transitions through the notes can create some beautiful movement and shifting harmonies in a musical passage.

DeepGliss could be a cool way to think about synths in a more orchestral sense. Even simple shifts played over a strong anchor note can sound fantastic.

The name DeepGliss comes from Deep Note (THX) and Glissando.

DeepGliss is available in VST format for macOS, Windows, and Linux. Set-up tutorial videos for Ableton and Bitwig are featured on the product page.

  1. Judging from the video it looks like a good tool for guitar pitch bender midi programming, will try – thanks James!

  2. I haven’t been able to get this to work in Reaper. The video demos are also not working on their website. Guess I’ll wait and see if it becomes usable at some point.
