Things to try that could help understanding what the problem is :

. Unplug midi jack
. Try with a different power supply (You use Dc in 9v ?)
. Power over usb
. Flash with a different SD card (and different power suply)

. Does it only freezes in edit mode ?  All mixer pages and the sequencer does work ?

No worry, if we don't find any solution, i'll swap yours with a working board.


EDITED : oh last question : does the blue led on the back stop blinking when it crashes ?

Ok, got a bit of time before work today and tried the following.

Unlugged MIDI in.

Removed 9v supply and swapped over to usb power.

Flashed firmware 0.110 using a different SD card under usb power.

Removed SD card.

Turned on, SD card error showed, mixer, pressed "edit", unit froze.

Turned off.

Turned on, SD card error showed, went through the mixer screens with no problem, then pressed edit, unit seemed to work without freezing.

Turned off.

Turned on, SD card error showed, mixer, pressed "edit", unit froze.

I recorded this and can upload the video later for you if you need me to.

When you say the led on the back of the board do I need to take it out of the case to see it? Not sure which led you mean

have you already tried a different sdcard? (not the same sdcard reformatted)

sometimes those cards go south...

I'll try flashing firmware tomorrow with a different card certainly, but it's a very specific error to be caused by an SD card identically over four firmware flashes and even with the SD card not inserted.  I really doubt it's the card tbh

When you say you "loaded" 0.110, you mean you flashed it ? You can see v0.110 in the top right of the menu ?
Just to make sure you did not just copy the firmware to the SD card.

Yeah, I flashed it properly and that's the version that shows on screen.

You saw the "SD card error #-6#" message ?
All instruments are then set to "sound"  ?
And it crashes when you press edit ?

Yup, I get the SD card error, a mixer page with everything set to sound, press Edit, it locks up.

Can upload a video if it helps but it doesn't show anything more than I describe

Unless you flash a corrupted firmware from the SD card.

I downloaded a fresh copy so I can't see how it would be corrupted?

That's worrying.

Welp, if I wasn't worried before, I am now...

Hiya, thanks for the post.

I loaded firmware 0.110 onto the machine, no change, crashed any time I pressed "EDIT"

I tried turning the machine on with no SD card inserted, crashed as soon as I pressed EDIT.

Reformatted the SD card, installed the SD image from the 0.105 firmware. Turn on, load patch, freezes.

If it was the SD card, is there any reason for the "edit" button to lock up the machine with no SD card inserted running .110 firmware?

Ok, I just reflashed the firmware 1.00 and now it freezes anytime I press "Edit" and is seemingly unusable...

It's been working fine for a week and now it's dead. I'm not really sure how. Really gutted.

I'll take a look at that asap. Thanks for the video.
Do you have the problem only when importing DX7 sysex patch ?

Nope, it happens when loading any patch or mixer.

Power on -> Menu -> Preset -> Load -> Load Patch -> Edit = Freeze

Power on -> Menu -> Preset -> DX7 -> Load -> Edit = Freeze

Power on -> Menu -> Mixer -> Load -> Load Mixer -> Edit = Freeze

I'm finding that I've I go to load a patch immediately after powering up and go to edit it, my fm3 freezes and locks up. It won't do anything until I unplug it and plug it back in.

If I turn on the unit and move around the menus a bit before loading a patch, it works fine.

Running firmware 1.0

Anyone else finding this?

I don't know how, but somehow I read everything on that wiki except for that page.

Thanks for pointing me in the right direction, I'll read through and give it a shot today.

This really is a fantastic synth, it's giving me a whole new world of sounds. I've really enjoyed the FM classics but also the incredible brutal noise it can make is just fantastic. Thanks for your work

« on: June 04, 2023, 12:35:04 AM »

Had my fm3 running for a week now and I love it. It's immediately found a permanent place in my setup.

I've learned a lot from reading through the fm2 manual and just spending time poking around, but for the life of me I cannot figure out anything to do with the sequencer. I am completely lost.

Does anyone know if there's any threads or documentation that can point me in the right direction? I'm always happy to RTFM but I can't even find a starting point.

Starting to think I bought the wrong button caps, these one sit far higher than the ones on photos of the fm3  :'(

Are these wrong? https://www.mouser.co.uk/ProductDetail/612-TA12-GRY

Any help much appreciated at this point

« on: May 21, 2023, 03:01:00 PM »

And found that the holes for the buttons are too small to fit the buttons through? Maybe .5mm too small all the way around.

Thought I'd finished the build successfully but bummed to find out that I can't use the faceplate without filing the cutouts to fit the buttons. Worried I'll end up with wonky gaps if not extremely careful.

Any advice from anyone who's had to do this already?

This is super interesting. Will these be suitable for DIY builds with the faceplate/ 3D printed case or are they tailored for the metal case you sell?

« on: May 10, 2023, 12:11:11 AM »

Thanks for confirming, I thought that was the case but just thought I'd double check.

I'm planning on making a walkthrough build video for YouTube for this DIY version as I've not made a video in a while and I thought it might be helpful for others. I'll post it here when done, hopefully you can let me know what you think of it.

Thanks again
