Hello!
I recently acquired a Tree Frog Enner and am loving it. What a fascinating instrument–truly astonishing. I have a question regarding sound coming from the center pyramid. When I am patching the center pyramid without input from either the pulse-side or synth-side, electrical hum emits from the Enner. Does anyone have any guidance on how to eliminate this hum?
Thanks so much!
Some hum/feedback/bleed-through when touching the center pyramid (especially the top portion/delay lines) without patching anything into it is normal. Especially with the L and R delay lines.
I also have a him issue that seems to have popped up only recently. When it first arrived everything seemed to function as should. The him is definitely a grounding him tone, and seems to attenuate all the other signals. Except for noise, all other segments in the pyramid have the same hum even when no other pad is being touched. I’ve swapped AC adapters but doesn’t seem to help.
Autocorrect tried to help, but in fact I have a hum issue that seems to have popped up only recently. When it first arrived everything seemed to function as should. The HUM is definitely a ground HUM type of tone which seems to attenuate all the other signals.

To get rid of the hum (ground problem):
1) connect the Enner to a grounded mixer.
2) if you don’t use mixer like me, use a proper alim : I use the power supply of Microfreak and it eliminated the hum. I think because microfreak has touchplates, Arturia found the right power supply.
I’ve got the very same ground hum, when touching the pyramid “Audio In”-plates which is absolutely annoying and makes the Enner unplayable.
Using the original power supply, tried a couple of others, but to no avail.
Me too I have the same hum output as you all reported. I tried to ground the Enner to the mixer ground but I to no avail. However, when I ground myself, the hum is a bit less when I touch the pyramid. Well, I’m gonna sell mine soon if this problem cannot be solved.
Evn thgough Soma stated in the documentation that you should connect the Enner to ground, then why did Soma not put a ground connector to the Enner?
It is normal that Enner exhibits more noise and hum than traditional synths, it’s inherent to the design and not a sign of a defect. Some days it will feel louder than others, but this will be a subjective experience.
Regarding ground, this is mentioned in the manual:
A normal grounding connection at the electric socket, which is carried through the power cord to your audio equipment to which the ENNER is connected, is sufficient.
This means that, as long as the rest of your studio/apartment/live setup has a proper ground, Enner will be grounded.
i have the same problem. feeding microfreak didn’t help. are there any other solutions? I can’t find the information anywhere. this post is the only one I could find. I don’t know how to do it. return the instrument or not. SOMA maybe you can advise?
My Enner has just developed this problem too. Right before a gig where it’s my main instrument, and it’s a key part of the entire performance 😬
I’ve had my Enner for about a year and previously no problems, both at more and gigging. Here at home it’s plugged into the same gear in the same house, same domestic electrical circuit.
Right now just raising my hand to say “me too”.
Soma, can we get some help here?

For tech support, please record a video with audio recorded to computer and send it to [email protected]. It’s important we see all settings clearly and how you play it.

Just got my Enner, yes humhum. My Soma reseller in Australia says that Soma is working on a grounded power supply, reseller awaiting delivery. If I use a pair of mono cables for output from Enner to my Cosmos, that have a metal shell around the jack and touch that shell the ground hum is reduce a lot. For me my best workaround for the moment is changing my playing style, so if I want to say pulse some notes press finger on constantly on one of the oscillator outputs and tap the pyramid. I will see if I have a ground line that I can connect to my body, that may solve the problem. But, yes, appears a grounded power supply (PSU) would be the better solution.
We have grounded PSUs available for sale from our SomaEU shop, and retailers can also order them. If you’d like to order one directly, just send an email to [email protected]
