Are you talking about this ?

I bought 3 pieces for 10 euros shipping inlcuded... I don't remember which one exactly.

They work very well and improved a lot the ratio signal/noise.

Thanks Paul for the good idea,
That shouldn't be complicated to add.

Will be in 1.52.  :D

Great... i'm glad it works...  :D

To upgrade the firmware you only have to screw off the 2 screws that links the top part to the rest of the box.
That's enough to reach the maple mini usb port.
Should take you 30 seconds ;-)

It should work with OSX (i've nver tried with a Mac but i do it everyday with Linux).
You must have dfu-util installed.

Follow the upgrade procedure but instead of running the *.cmd file,  run directly the command line :
dfu-util -a1 -d 0x1EAF:0x0003 -D PreenFM_R3_v1.51.bin -R

Hi Nick,

The LCD is OK.
The Maple blinks so it is powered...
Can you hear the boot sound ?

I think you don't have any choice. You have to take off the knobs and remove the top plate, the LCD etc... and check the connections.
On my dev board, i put on and off many times the knobs... It's easier each time ;-)
Take the board firmly just bellow the knob you remove and it should be OK.

Could you check the points i colored in the attached schema ?
When trying again the LCD, no need to rebuild the case, just plug quickly the LCD for verification.
Plug the USB after plugging the LCD else the LCD will miss the first initialization command.

Let me know how it goes,

Xavier

Great !  :D
Thank you for the fast confirmation... and for having reported this bug.

Now i have to reflash the 45 maple minis that are waiting to be packaged... Aouch...

Seems like you can upgrade to 1.51  ;)

Simple Midi clock also broke the audio engine.
It should be fixed in 1.51.B1...

Please, let me know if it solves anything on your side.
Thanks for your help  :D

OK thanks.
I think i know what happens.

In Ableton Live, can you disable "Midi TimeCode" for the midi output sent to the PreenFM ?

I hadn't realized Midi TimeCode sends information with the SysEx protocol.
The PreenFM Audio engine stops while waiting for the end of SysEx messages which can make these little audio glitches...
I'll confirm that soon. I didn't check with the code yet.

That's bad. I have to fix that.

Loderbast, do you also use ableton live ?
I just tried several midi config with Reaper and i could not reproduce anything like this.

If you have a midi file I could use that would be great ?
Also, i'm currently downloading a Free-30 days live trial version. Maybe the problem will be obvious with live.

Hi, thanks for the feedback.

I'm not sure i get it.
With an external controller (mid keyboard ?) it works.

But with Ableton Live and with your hardware sequener there's a problem ? Right ?
What is the exact problem ? Notes don't stop ? They are cut ? they are played several times ?

Do you replay something you record with a keyboard or do you use a kind of midi algorithm to send the notes ?
I may be wrong, but I suspect the midi notes to arrive too quickly and as PreenFM polyphony is limited, the rendering is not smooth.

I doubt trying with an other firmware will solve anything.

Could you record the midi that makes the note stuterring in a midi file and send it to me ?
I'd like also to hear what you hear ? Could you record it ?

Hi Julien,

Thanks for your post, i love that kind of post  :D
I think you don't have to upgrade the firmware because you have the last one ;-)
When you power on the PreenFM, you should see 1.50 somewhere. If it's the case, you are up to date.

1.50 is the same as 1.50.Beta4.
I will make a official annoucement next week, when all the kits are ready to ship.

Congrats for the fast build.
Enjoy your new sound module, and don't hesitate to share your patches ;-)

WOW... congratulations.  :)
I'm glad to read that, because the resistor sheet takes me lots of time to prepare ;-)

Don't forget to le me know when you use it in a track.
