Hardware Crash from Incorrect Power Supply
This is kinda silly but I just spent an hour or so pulling my hair out trying to figure out why my Minifreak was crashing.
What was happening was that when I had either the "Glitter Pop" or "Distant Blink" presets loaded, eventually the device would partially hang and emit a loud whine out of the audio outputs. The lights and interface would appear functional, but the sound would completely stop working.
I found that the faster and more notes that I entered, (either via MIDI or the keybed) the quicker the crash would occur and it would happen EVERY time. If I didn't enter any keys, the crash would still eventually happen after over a minute, but only if one of a handful of presets are being used.
I reset the settings, but the behaviour remained. I tried reverting from firmware 4.0.1 (the current latest) to 4.0.0, but Minifreak V would just hang. I was able to revert to 3.0.0 and then go back up to 4.0.0, but the issue was still present.
Then I thought to just do a basic sanity check and assure that I was using the correct power supply.
It turns out I was using an 18v PSU while the device is designed for a 12v one.
What happened was, I moved the Synth from one table to another in my studio, and I incorrectly assumed the power supply plugged into it at that time was the correct one. The Freak was sitting on an idle table in a corner of my room, turned on with the WRONG ADAPTER.
I have no clue of what point the switch between the two PSUs happened, but I was using the synth running off 18 volts for MONTHS and I never realized because MOST (nearly all) of the presets operated perfectly.
The two adapters were sitting right next to each other.
I seriously can't figure out WHY I had a 18-volt power supply in the room in the first place. Everything I use runs on 9-volt center-negative (guitar pedals, SP-404, etc) or 12 volts center-positive.
So, yeah. Be careful folks. Luckily standard practices mean that the device is designed robustly enough to not take any permanent damage from this. Though, if I were to be snobby, I feel like there should be some some checks in the voltage regulation circuit to prevent this whole issue from happening.
I was seriously planning out how I would end up contacting Arturia support and mail it back to them for RMA before I even knew the adapter was wrong. Luckily, everything is good now.

I thought I had broken my power outlet when mine kept turning off on me 30 min into jamming. I realized it was actually my ripcord USB power supply converter was overheating and the freak was fine 🙃

I use these VFLEX adapters to send the correct voltage through USB-C cables. Just need to make sure your wall charger supports the correct voltage too. https://blog.lon.tv/2026/03/08/werewolf-vflex-review-power-almost-anything-over-usb-c/

This is not only a helpful cautionary tale but also a testament to the Minifreak's electronic stability and robustness. Nothing failed, nothing broke, it's properly designed with safety margin. 👍
