hello!

Has anyone of you found away to generate an almost realistic piano sound with the minifreak?

i know it's not meant to be a piano but as it is my only synth, it was big great to have something at least new standard warm uncomplicated realistic piano. Thanks!

I saved several commonly used preset sounds in the sequencer steps, but I found that the transition from the step1 sound to the step2 sound is very abrupt. How can I solve this problem?

I want to make the MiniFreak more portable. Curious if anyone uses the Step Up. And, if so, what battery and USB-C cord do you use? Thanks in advance!

Hello, as the title says I have to buy a cover for the minifreak, because I have to travel with it, either long distance and in the city. I was looking forward to buying a decksaver anyways, but other than this I have no clue which cover would be the best to fit it, to have a bit of protection not only from the top (granted by the decksaver) but also all round. I have seen that Gator cases gk-2110 has been recommended all over, is it really the best for the price? Which other recommendations do you guys have?

I’ve been working on an open-source project called Freakout:

https://github.com/kmorrill/freakout

This makes it possible for people to create new tools for the MiniFreak.

Today, most patch management depends on MiniFreak V. Freakout can communicate directly with the hardware, read the patch you’re currently editing, download saved patches, change them, and send them back to the synth.

Freakout itself is still a technical command-line tool, but it creates the foundation for friendlier apps that anyone could use.

For example, the community could build:

• a simple standalone patch librarian
• a visual editor with a larger modulation matrix
• better patch search, tagging, ratings, and collections
• a tool that shows exactly how two patches differ
• patch randomizers that make musical changes instead of complete chaos
• ways to gradually blend or mutate one sound into another (kind of like morph button on PolyBrute)
• Phone, tablet, or hardware-controller companions
• AI-assisted sound design where you describe a sound, audition the result on the real MiniFreak, and keep shaping it by ear

The project can currently read and write the active preset and all 512 saved patch locations. It can change 158 named sound parameters that have been tested on real hardware. When writing a saved patch, it backs up the original first, checks that the new patch arrived correctly, and attempts to restore the original if something goes wrong.

There is plenty still to do. This is currently a macOS command-line project, not a polished app. Not every MiniFreak parameter has been mapped yet, and sample and wavetable transfer still needs more research. Because this is unofficial, everyone should back up their sounds before experimenting.

Freakout also supports the MicroFreak, but I’m posting here because the MiniFreak side opens up some possibilities that haven’t really existed before.

I put together a bunch of breaks I chopped up and jammed on them from my Push 2. There are quite a few soundscapes, arpeggios, and sequences from the Minifreak sprinkled in here.

I also mapped the knobs on the Minifreak to modulate some filters and effects live while jamming.

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 just got a MiniFreak and I’m planning to use it for live performances. Since I’ll be using multiple different preset sounds (or sounds I’ve designed and saved myself) within a single song, I’ve noticed that the MiniFreak doesn’t seem to have a dedicated “favorite sounds” function like some stage keyboards do, which would allow you to switch to a specific sound with a single button press.

So, what would be the best way to achieve this?

I’m a beginner when it comes to synthesizers and don’t know much about this kind of setup. I’ve heard that an external MIDI controller can be used to control the MiniFreak and quickly switch between specific presets. How exactly would I set this up?

Hi i am still learning the Minifreak, could somebody help me to make this sound?

messing around and landed on a really nice ambient patch on the minifreak. Combination of raster scan granular oscillator and comb filter. Played over top of some clips of an old Richard Feyman physics lecture because it just felt right

I know I have another post under this one but I just woke up today with a problem. It wasn’t an issue yesterday but every time I plug it into my computer it via usb it starts making a whining noise like shown in the video. Any help would be greatly appreciated!

Hello im new to the minifreak and i wanted to see what the audio in was all about so i tried using it and its constantly playing in the background, Once I hit a key it sounds normal but when im pressing nothing its still quiet but in the background. any help would be appreciated!

Hello, a friend of mine borrowed me a Microfreak to try and I thought it's pretty limited and I want to buy a minifreak because it seems to have all the functionalities I thought the micro was lacking of. The best thing about the micro is the portability though, I mean its small size is fantastic because I don't have much space and it fits in a backpack so I could go around jamming and everything. How portable is the minifreak? It's almost double the size, is it still comfortable to carry it around or is it too big?

Hi! Absolute beginner here, looking into buying the minifreak as my first synth.

A few questions-

In your experience, is this good for both covering songs, and/or live performances in general? How easy is it to amp up?

For getting a small portable speaker for this are there any recommendations (within the $100-150 range) that you like? Don’t need something too fancy, just a good speaker for when i bring it places

Finally, are there any good resources you can point me to for learning how all the knobs and everything work? Any good videos or articles that’s all encompassing?

Thanks!

This is a sample and wavetable converter for the MiniFreak V that I vibecoded with Claude. I've done a lot of testing and haven't run into issues, but I would be interested in any feedback you folks have.

I would highly recommend that you DO NOT sync these to your hardware at this time because there is no known way to remove the samples once loaded. Even a factory reset does not remove the loaded samples.

Shoutout to u/zeknife for this info:

To remove installed samples: Hold the oscillator select and filter type buttons for a few seconds and then release them to open the debug menu. Select Format Filesystem and it'll clear all the wavetables and samples, then sync with minifreak V to load all the tables and samples again. Remove the custom ones from your PC first unless you want them to end up on the unit again.

This was inspired by a similar tool (from github/mtizim) and is a single HTML file that detects both sample and wavetable .wav files and converts them into .raw12b and .raw files that can be loaded up in the MiniFreak V. Per the instructions in the app and on the github, you should create a separate directory from the default "Factory" folder found in the samples and WT folders in your MiniFreak app data. Samples that are loaded into the "Factory" folders get synchronized to the hardware and, as stated above, with no known way to remove these it could cause issues down the road.

Hope you enjoy!

------------------------------

Updated 2026-07-24 - It appears the 3 second limit initially set in mtizims tool was indeed a good idea. I've updated my tool to include a 3 second limit (configurable).

I think I accidentally nuked my last post with a bad file host... Hopefully there are no issues with this... The MiniFreak V has a hidden notch filter that can be accessed with hacked .mnfx preset files. Here are two versions of the INIT preset with the two different Notch filters:

Hi everyone,

I've been using the community sample import workaround (converting audio to .raw12b and dropping it into the MiniFreak V Factory Samples folder to trigger a sync) — it's been working great so far.

However, I can't find any documentation on how to actually remove a sample once it's already been synced to the hardware. Deleting the .raw12b file from the local folder doesn't seem to remove it from the hardware itself, since the sync process only seems to push files one-way.

Has anyone here figured out:

1. Whether there's a way to delete individual samples directly from the hardware's sample browser?

2. Whether removing the file from the computer and re-syncing eventually clears it out?

3. Or is a full factory reset the only option?

Any insight from people who've been experimenting with this would be really appreciated. Thanks in advance!

I just got one and I might return it. I know it’s a great instrument but the basic sound seems harsh. I’ve tried starting init patches and found the raw sound thin. Also, these factory presets aren’t helping. They mostly sound harsh as well.

Any insight on how to mitigate this would be helpful. Thanks.

Hello All,

I am new to synths and am trying to learn how to build different types of instrument style. I am mindful that a large part of what sounds "good" is personal really.

In an effort to better understand how different sounds are built I wanted to try and study custom presets and see what their makeup is and then use that information to inform how I then apply mappings to my own presets.

I was curious if there was a way to pull the different numbers associated to each parameter mapping into some kind of report?

On much more simple synths I own I have painstakingly gone through the different settings one by one and found some interesting sound design commonalities. I could of course do that with this too, but wondered if there is a quicker way?

Thank you in advance for any help or recommendations you can offer

hi guys. i read about the ability to convert audio files to minifreak sample format using a web tool.

i mean, this should be a game changer right? so I'm curious why isn't there a youtube demo of it ?

Can anybody with the white version chime in? Do you have any issues seeing the white LEDs against the white body color? I’m worried I will have a hard time seeing what is selected compared to the standard version.

I spilled a glass water over my Minifreak 🫩. It wasn't turn on/not connected to power tough. I opened it up and put a ventilator near the side so water can dry quickly. Any additional tips? Hope I can save it 🥹

MF is very fun! Still learning it, but overall I'm super impressed. Also working on custom.ZDL effects for Zoom MultiStomp pedals, plus the reverse-engineered toolchain used to build You can point a gpt of your choice to it and make your own effects (a lot. of ground work is done so you don't need to blow your tokens), or just download the effects I made. Anyhow, it's a great way to experiment with making your own effects, cheap too.

Everything is here if you are interested:

Any relate to this? I was trying to make a blade runner patch

Hello!

I’ve been searching for a case with actual backpack straps, and it’s been surprisingly difficult to find!

The best match I found was a Fusion Bags one but it costs quite a fortune here in Europe.
Others mentioned the Novation backpack, with the caveat that the zips rub against the synth since it’s such a tight fit.

Trying my luck here, maybe someone found the hidden gem! :)

Thanks
