Noise When H90 Connected to Computer for H90 Control Editing

[Jimi1983]

Hello All

I’m brand new to the H90 and loving it. I just connected it to my Mac computer to do some edits with H90 Control.  I’m using the latest H90 software the H90 Control software.

Unfortunately, when the USB is connected from the the computer to the H90, while I I can hear my guitar and the H90 through my amp, I’m getting an annoying background “hum” (for lack of a better term).  This makes it hard to listen clearly to discern the preset I’m editing. I’ve tried replacing the USB cable and also tried switching power strips, etc., but the problem remains.

Any ideas of what I can do to resolve the problem?  Thanks!

Hello,

How are you using the H90? Mode? What’s your signal flow? Amp model, loop, clean or distorted?

Do you have a groundlift?

For me An isolation box worked.

Maybe if you can, use bluetooth.

This is indicative of a ground loop in your system which can be challenging to track down. USB interference is a common studio problem. Since you’re on a Mac use Bluetooth to connect to H90 Control. That will eliminate this issue.

Thanks to you both!  I’ll try Bluetooth.

Checking back in on this as I’ve had success pairing H90 Control on my iPad with my H90.  Works great.  However, while it appears from my computer that I have connected my Mac with the H90, in H90 Control when I click Bluetooth to add device, it shows a quick popup saying “Pair H90 using Bluetooth”, but I can’t click on it. So apparently H90 Control is not connected with the H90 (although the H90 shows my Mac on the Bluetooth page).  What am I doing wrong?   Is there a manual with instructions for doing this?

[tbskoglund]

All of the information for Bluetooth pairing/connection can be found here: https://cdn.eventideaudio.com/manuals/h90/1.7.5/content/system-menu/bluetooth.html

Please carefully follow the instructions as there are specific steps for this to work properly. Let me know what happens.

Thanks for the assistance but bluetooth connection between my iMac and the H90 is still not working.  I’m using the latest software on H90 and latest H90 Control.  I configured everything fine w/ my iPad, and it works properly on it, but not so with my iMac (running Monterey 12.7.1) which is what I’d greatly prefer using.  Here is what happens:

I follow the directions for Bluetooth connection as provided.  I enable Bluetooth on the H90, then click the Bluetooth icon on H90 Control on my iMac  The H90 shows up as available in my Bluetooth Configuration window.  I click the “connect button”, and the button temporarily shows it as “connecting”.  However, the H90 Bluetooth shuts off, and the H90 no longer shows up on my Bluetooth configuration as being available.

Thanks!

Since you have switched between devices (iMac to iPad) you need to forget the H90 in iMac Bluetooth settings and forget the pass key on the H90. Then, try to re-pair to your iMac again. What is happening is the H90 remembers the pass key for the iPad but not the iMac.

[Dirtykeys]

I’ve this same issue. iMac and H90. Connects… then disconnects.

and it’s not been paired with anything else.

I just bite it. And use the usb(hum and all).

[tbskoglund]

Sounds like you may need to try the steps Joe mentioned above. Please try the “forget” option on the pedal, as well as forgetting the H90 from your Mac Bluetooth settings, and then repair the H90 again.

https://cdn.eventideaudio.com/manuals/h90/1.7.5/content/system-menu/bluetooth.html#macos-connection

Let me know if that works.

[Dirtykeys]

Naw. Did all that.

 

it’ll say connecting (on the Mac).

 

and then disappear and turn the Bluetooth off on the h90.

No fucking biggie, honestly. I like to have a majority of instrument shit hardlined in.

 

 

[Jimi1983]

I also continue to have the Bluetooth connection problem, and I really want to make bluetooth work on my Mac (rather than just the IPad) or the hardwiring due to noise.

 

I thought I had my computer (and my IPad) forget the H90 and used Mac instructions for doing so (I’m running Monterey) and vice versa.Afterwaards, the H90 does not show up in my computer’s bluetooth configuration.  However, when I go thru the H90 control connection process as described in the H90 instructions the H90 shows up again with an available “connect” button and I can’t connect.

I rarely have technical problems like this, and think I must be doing something stupid.  Appears that somehow the H90 is still available in my computer’s Bluetooth devices even though it’s out showing up in my /Bluetooth configuration?  Can anyone please share your method for completely forgetting the H90 on a Mac so I can make this work?

 

Thanks!

Sorry to hear you are still having issues.

As mentioned in the user manual, some Macs running macOS 12 (Monterey) have known issues pairing with Bluetooth MIDI devices. If you are having trouble pairing your device on Monterey, updating to macOS 13 (Ventura) has been known to resolve these issues.

I cannot confirm if that is the issue you are having. If you’d prefer not to update your OS yet, you can contact support@eventide.com and we can get some further information from you that can help us determine if the update is necessary.

Bluetooth disappearing on the H90 is indicative that the Passkey on the H90 does not match the device trying to be linked. Try these steps:

1.On the H90, go into the System menu > Bluetooth and press the 3rd quick knob labeled <forget>. Press again to confirm.
2.On the Mac, go into the Bluetooth prefences. In the Devices list, click the X next to the serial number of the H90. It should prompt you with a box that asks, “Are you sure you want to remove “XC-serial#”. Click Remove.
3.On the H90, turn on Bluetooth by turning the first quick knob in the Bluetooth settings. You should see the blue light turn on.
4. On the Mac, open up H90 Control and click the Bluetooth symbol at the top right. You will see a Bluetooth Configuration pop-up where you’ll see the serial number of your H90. Click “connect.” Immediately, you will see a connection request pop-up where you need to put the passkey that appears on the H90 screen.
5. Once this is complete, you’ll see the icon for your pedal on the Home Screen with a button that says “Connect.” Press this to control your pedal. If you do not see an icon on the Home Screen, click “Add Device” and select it from the Select Port drop-down menu.

i’ve just gone head first into the wall to try solve this very problem on my setup…
was never able to connect via BT, only USB (and it ain’t always possible).

[FYR: MacBook Pro 16-inch 2021 | M1 Pro | macOS 14.5 Sonoma | latest safety features | H90 Software 1.8.6.72 | H90 Control 1.7.11].

thought someone might appreciate one further hint here, if it helps them to find their way around.
i for myself, too, had tried all that was noted here, to no avail: there simply was no H90(serial number) to “forget” in my System Settings’ Bluetooth panel.

i realized there’s no longer a GUI switch in Sonoma to wipe the BT manifest clean, in order to force it start to court for pairing.
i’ve launched a Terminal instance, into which i typed: sudo pkill bluetoothd

if your user has admin privileges, it simply takes your pwd, enter.
all other devices that were there before won’t fade away – so no fear, no sweat, it takes less than 1 minute in total.

a few seconds later, H90 was showing up among all my other Bluetooth devices.
which is when, finally, passkey request popped up my screen.

then (and only then) the process of adding it within H90 Control via BT worked.
now both LEDs are solid blue… and i can stash the USB cable into the drawer, until next firmware update.

note: in this respect, being able to update my H9’s firmware over Bluetooth is so much more comfortable…
hope it’ll get to work on H90, too – and soon, maybe!

[tbskoglund]

Thanks for posting your findings. We will look into the Bluetooth settings on Sonoma and see if there is an easier way to do this.

Sorry, but we won’t be able to offer updates via Bluetooth.

Hi all , recently bought the H90 and I’m experiencing same issues .

It is very noisy (amp) connected to pc via usb , and cant seem to have a stable connection via bluetooth to my windows PC

it connects and straight away connection drops

It is very frustrating

<p style=”text-align: center;”>Done all that and no luck</p>
By the way , im using a windows 11 not a Mac

[Dirtykeys]

Same process. Insert “windows” where Mac exists.

[tbskoglund]

Sorry, we do not support Bluetooth connections on Windows devices since windows does not offer over MIDI over Bluetooth.

You’ll need to use the USB connection for Windows, or use an iPad or Mac to connect via Bluetooth.

You can troubleshoot the USB noise issue by trying different configurations of how your devices are powered. It is best to have all devices (H90/computer/anything else in the signal chain) powered from a single outlet/source to avoid ground loop issues.

[Piloti]

That sucks , but i had a feeling that’s what was wrong with it

I really appreciatte the heads up

Thank you
