And Eventide have really pulled out all the stops on this new and improved edition - where you can essentially consider the new H90 as being 2 x H9 Max’s together as you can select 2 algorithms to play back at a time - with all kinds of clever wiring / cabling and routing options - parallel and series - for ultimate stereo output fidelity.Įventide has picked up all kinds of cool cues here from both the Line 6 Helix Stomp, and the Boss GT-1000 CORE equivalent - and has a little of the GFI Synesthesia in there too - where the new onboard control interface and topology is massively improved and far more logical and intuitive than the H9 ever was. Multitudes of us have been asking for a better and more intuitive interface - with more meaningful screen display. There is much to recommend the H9 - but its on-pedal interface has always been somewhat feeble, and without the superb Bluetooth connected App the pedal wouldn’t really have been particularly usable. Check out today's blog in which we cover the world's first harmonizer, the H910.As a long-term user and fan of Eventide’s H9 Max, the H90 Harmonizer has been something we have all been clamouring for - for a very long time. While Pitch Change is naturally occurring, throughout history, humans would rarely have perceived the effect because the sound source must be traveling at a high enough rate of speed relative to the listener to cause a discernible change in pitch. Why had no one elucidated this effect in our long history? It’s simple few things moved fast enough! Sound travels at ~750 mph.

To notice even a slight pitch change of 2% a sound source with 100% constant pitch would have to be approaching the listener at 15 mph. (Kids whirling objects around on a string were not the scientific observers for which one would have hoped.)

In 1842, Christian Doppler suggested that “the observed frequency of a wave depends on the relative speed of the source and the observer.” Doppler was thinking about star light, not sound, but a wave is a wave is a wave. Just three years later, Buys Ballot, a Dutchman, demonstrated the Doppler Effect on sound waves by having six tubas play the same sustained note while perched on the front of a speeding locomotive. harmonizerįrom now through May 3rd, 2021 you can get the H910 plug-in for only $50!Īnd now we present Flashback #4.2. The H910 was arguably the first pro audio digital effects product.
