Features:
- Keyboard and MIDI mapping – The original H910 featured a keyboard remote control which was used live by several artists including Elton John. With the H910 plug-in you can easily use MIDI to control pitch and harmonization in real-time.
- Envelope Follower – An envelope follower has also been implemented in this latest release. Engineers and producers discovered that sending a control voltage to the hardware H910 could be used to slightly (or massively) vary the pitch, creating entirely new sounds. The built-in envelope follower makes exploring these possibilities easy.
- OUT2 Delay Group – adds inspiring attributes to your sound.
- True analog modeling of highly nonlinear electronics for faithful reproduction of the original H910’s juicyness and grit.
- Perform perfect pitch changes controlled manually, via MIDI or with Anti-Feedback.
- Anti-Feedback modulates the pitch around unity for a subtle or wild effect.
- Optional “glitching” of original H910 hardware to create unpredictable sounds as it alters pitch.
- Modify pitch by musical intervals (diatonic) to harmonize vocals or solo instruments.
- Delay rhythms and melodies to create everything from slap-back echoes to feedback chaos.
- Create colorful, unique sound effects and drones through self-oscillation.
- Individually control delay outputs and dry/wet mix.
- Mix Lock allows for scrolling through presets or settings while keeping the dry/wet mix constant.
BONUS: H910 Dual:
- H910 Dual recreates two H910 units running in parallel to create doubling effects and other unique sounds.
- H910 Dual easily fattens and thickens instruments when assigning opposite pitch ratios.
- H910 Dual Stereo (cross-unit) Feedback can cause the incoming signal to shift up and then down continuously.

I love the sound of this! It allows you to get that independent slightly pitched sound on each side that creates width on mono sourced tracks, or even enhancement of stereo tracks. I love it on guitar and vocals.

Very cool sound and also a great piece of history for educational purposes.
