Hi Eventide-Staff,
I just bought second H9 MAX last week, just to find out that you’re now releasing a Gen2 🙂
I’m super exited for it!!! One reason for owning two H9s is that so I can switch between two sounds without the preset-loading lag/delay. So I have a few questions about the H9 Gen2:– Will there be seamless Preset/Program switching without a lag/delay? (I don’t mean “trails-spillover”)
– I use a lot of the Distortion Algorithms: So can Gen2 switch from Crushstation to Sculpt instantly?
– How will the switch between PGM UP/DOWN-Mode of the right Footswitch be handled? Long-Press?
– Will the right Footswitch be programmable which a specific function? Hotswitch, Tuner, etc?
– Will the Gen2 have more than one Hotswitch Setting per Algorithm, like the H90. Loadable via Midi?That’s all I can think of for now. Thank you for making such awesome products.
Kind regards -

Hello Genemesiz,
We appreciate your excitement of the H9 Harmonizer Gen 2 preorder announcement. We’re happy to give some basic answers to your questions but want to leave the deeper discussion for the actual release on June 24th.
Will there be seamless Preset/Program switching without a lag/delay? (I don’t mean “trails-spillover”) – I use a lot of the Distortion Algorithms: So can Gen2 switch from Crushstation to Sculpt instantly?
This is a significantly faster processor than the H9 Max. We’ve tried and found the H9 Harmonizer Gen 2 to be much faster than the H9 Max.
How will the switch between PGM UP/DOWN-Mode of the right Footswitch be handled? Long-Press?
You are correct, long pressing the right footswitch in SELECT mode will change the direction of the preset search as will the LED button above the footswtich.
Will the right Footswitch be programmable which a specific function? Hotswitch, Tuner, etc?
Yes, one of H9 Harmonizer Gen 2’s most powerful features. Left and right footswitch!
Will the Gen2 have more than one Hotswitch Setting per Algorithm, like the H90. Loadable via Midi?
Another H9 Harmonizer Gen 2 upgrade!
That’s all I can think of for now. Thank you for making such awesome products. Kind regards
We’re looking forward to showing the world everything on June 24th.

Thanks joecozzi for the infos. I´m very exited for it.
I understand that you can’t reveal all the details before the big release, but what would tip me over the edge to pre-ordering it are these additional questions:
– Sure there is small Delay. But is it half, a quarter, or a tenth of the h9?
– Can the H9 Gen2 keep the current sound until the new algo is loaded? What makes using Distortions on the H9 so difficult is not only the delay while loading, but that there is the significant drop-out to the pure dry sound while loading.
– How many MIDI loadable HotSwitch Settings will the H9 Gen2 have? This would improve the workflow, especially for my use-case with having multiple Distortions sounds and load them instantly.Thank you very much

I think H9 users looking to upgrade will be thrilled. Only way to know for sure is to try it out in your own rig. In PERFORM mode, you will have access to two Hotswitches, one per Switch. Questions on deeper MIDI functionality will be answered upon release.

Will the screen be visible in outdoor daylight? At my first daytime outdoor gig with my H90 I was unpleasantly surprised that the screen became invisible even with shade. Will the 2nd gen H9 have a more outdoor daytime friendly screen?
-
June 5, 2026 at 1:05 pm #195680
There’s a new display on the H9 Harmonizer Gen 2 altogether. I definitely feel it’s an upgrade for daytime visibility over the H90, will run tests when it’s ready.

Will there be a global volume control like the original H9?
-
June 5, 2026 at 4:48 pm #195682
There won’t be a global volume control, but rather each preset now has its own input and output parameters for better fine tuning. In addition, the H9 Harmonizer Gen 2, like the H90, will now allow for separate instrument or line level operation options for inputs and outputs.

Hello!
Will the H9 Gen 2 be similar to the H90 in terms of Relay and DSP bypass? I assume no analog dry-through features?
Thanks

June 6, 2026 at 2:39 pm #195689
Hi Joe, very excited about the H9 Gen 2. I’m curious, how is the software dev going? Is there a functioning H9 Gen 2 Control app already? Any easy compatibility with saved preset banks from the H9 Gen 1 Control app?
-
June 8, 2026 at 9:10 am #195696
Software dev is ongoing. Control app will be available with the ability to import Gen 1 presets & lists.

June 7, 2026 at 5:36 am #195691
Hi Joe, thanks for your help, will you please share input and output impedance values?
-
June 8, 2026 at 1:21 pm #195703
Details forthcoming, but H9 Harmonizer Gen 2 will allow dedicated line level and instrument level operating modes.

Will the Gen 2 work with the Barn3 OX9? Will the screw holes be the same?
-
June 8, 2026 at 9:03 am #195695
It will not work with the OX9 as holes do not line up and neither do the cable and inputs. We recommend using the new OXU Mini with mounting plate.

How will the signal routing work on this?
Are we going to be able to use the 4 Cable Method (or just an insert loop) and still have stereo outputs? What are the other routing options that will be enabled?
-
June 11, 2026 at 5:35 pm #195759
There will be Pre/Post (4CM) and Wet/Dry routing modes. The routing is the same as the original H9 if you are familiar with that:
- In Pre/Post, you have a mono Pre path and a mono Post path.
- In Wet/Dry, you have a mono Wet path, and a mono Dry path.

Is the midi implementation the same as h90 ?
-
June 17, 2026 at 6:00 pm #195798
Yes.
-
-
June 13, 2026 at 7:12 pm #195775
is the looper stereo like the H90 or mono like timefactor?
-
June 13, 2026 at 8:24 pm #195776
Stereo
-
-
June 13, 2026 at 9:18 pm #195777
great!
im guessing you can’t load 2 algos at once tho, this is saved for the H90?
-
June 13, 2026 at 11:01 pm #195778
Correct. One algorithm.

Can you use USB connection for midi?
when will manual be released?
-
June 17, 2026 at 5:59 pm #195797
Yes, the new H9 can receive MIDI over USB. Manual will be available on release day, June 24th.

Question: there was a number of complaints about the Harmonizer+ algorithms such as VocalTune in the H90 having unusuably high latency for live vocal processing (more than 30ms). Has this been optimized in the H9 Gen 2? Is there any way I can find out the values there? If it is low – I will be buying day 1.
Thank you!
-
June 24, 2026 at 3:01 pm #195908
Hello,
The latency of the Harmonizer+ algorithms is the same on the H90 and the H9.
We designed the vocal algorithms to have the best tracking and harmonizing that we could offer. There is a tradeoff between the quality of the effects and how much latency is introduced, and we ended up with a balance that we felt was right for most vocal applications. However, we realize that less latency is desired and we’re looking into ways to improve this.

Pedal arrived from B&H Photo today. It’s amazing. I never really needed 2 algorithms on the H90. Pretty much exclusively using it as a pitch shifter (polyphony).
With the tuner not available in perform mode, it probably won’t replace my st-300 on the board.
I think it’s been brought up before but still hoping at some point Freeze functionality is greatly expanded on the H9/H90 pedal. If there’s ever a fully developed Superego Plus esque freeze algorithm, I’d go back to the H90 in a heartbeat.
Anyways, congrats on the pedal Eventide 🎉

With the tuner not available in perform mode, it probably won’t replace my st-300 on the board.
True, the Tuner is not accessible from the front panel switches when in PERFORM mode. The way around this is mapping the tuner to an aux switch. Now, the tuner will appear even when in PERFORM mode.

Apologies if already asked, but will the gen 2 have a similar ‘LEARN’ function as on the h90 for diatonic pitch effects? Thanks!
-
June 27, 2026 at 4:58 pm #195952
Yes, it will have the LEARN function for the same algorithms where that is featured on the H90.

June 28, 2026 at 7:28 pm #195956
Our band is tuned to A=444 rather than A=440. Will the harmonizer designed to work with microphone vocal inputs track with us at this tuning or will it “correct” things to normal concert pitch? (A=440)
-
June 29, 2026 at 10:19 am #195959
The VocalTune algorithm has a tuning reference parameter that would allow you to set A 444.
The other Harmonizer+ algorithms do not have this parameter, but we could consider adding it in a future update.

Does the H9 Gen2 have new factory presets in the algorithms that are not on the H90? Thanks!
-
June 30, 2026 at 4:09 pm #195977
Yes! It comes with over 1000+ presets including some brand new ones.

MIDI implementation wish list item #1: allow user to switch between user profiles via midi CC. Or is that unrealistic?
-
July 2, 2026 at 1:22 pm #195986
Are you requesting to be able to change the Playlist is in the system settings using a MIDI CC? https://cdn.eventideaudio.com/manuals/h9/1.0.0/en/content/system-menu/global.html
-
July 2, 2026 at 2:19 pm #195989
Correct. I am not finding the appropriate menu option to perform that action.
-
July 2, 2026 at 3:14 pm #195992
Thanks, I just wanted to confirm what you were requesting.
You can only change the Playlist from the system settings or using the Eventide Control app, but we can consider changing this with a MIDI CC in a future update.

-
July 2, 2026 at 1:31 pm #195987
Yes, I may have not understood the instruction the first time I read it. I will experiment with it some more.

Hi,
How can I turn BT on / off, so that I can use the h90 control app on iPad?
How can I change presets from Eventide Control app v2.1.5 running on Mac? I can change them from the hardware preset button and big knob. On h90 it all can be done from the app.
I’m using software v 1.1.7.135
Thanks
-
July 3, 2026 at 10:52 am #195998
Hello,
Bluetooth is not yet available for the H9 Gen 2. It will be available in a future update.
You can select different presets by connecting the H9 to Eventide Control and clicking the Presets tab at the top.
Eventide Control will be available for the iPad in a future update.

Could we get the H9 Gen 2 presets for the H90?
-
July 6, 2026 at 7:19 pm #196028
I’m trying to get my Roland EV5 to work with the H9 Gen2 and have had no luck. Won’t go to zero or 100%. I’ve tried a ton of different stuff and it still will not work. The auto calibration seems to be a bit vague and unless I’m missing something, it’s not working at all. I even tried my Ernie ball volume pedal connected with a TRS cable, which gave different, but similar results. Any help would be greatly appreciated
-
July 6, 2026 at 9:42 pm #196029
It’s best practice to connect to an expression pedal or aux switch first before connecting to either input. This way the H9 can accurately sense the load. To calibrate an expression pedal on the H9, enter the System Menu and choose I/O. On the third page of settings, we find the Calibration section featuring indicators for the pedal sweep and circles that light up when switches are pressed. When Calibration is set to ON with the third quick knob move the expression pedal from heel to toe until the display shows a zero to 100 sweep range ensuring proper detection. If the sweep behaves erratically or goes up and back down again, check to make sure you’re connecting to the H9 with the appropriate cable. Some expression pedals only work with a TS cable, others use a TRS cable. Also, watch out for any internal dip switches or extra potentiometers. Some expression pedals use them to reverse the direction of the sweep or adjust the pedal’s response curve. Eventide recommends expression pedals with a 10 Kiloohm – 25 Kiloohm linear potentiometer. While higher ratings work, it may cause the range to be compressed at one end of the pedal sweep. It’s best to stick with this recommendation. I know the Ernie Ball has two versions of of VP JR, one that has a 250K (6180) pot and another that is 25K (6181), make sure it’s the latter.

I figured it out. Had to do it through the actual H9 and not the control app. Thanks for the response!
