PreenFM2 / Re: PreenFM2 will not turn on

But you need to close those headers with a small piece that should be on the packaging making connection between the 2 pins, that you soldered them it does not mean they are closed.

Yeah Jumper 1 and 2 are both populated with 2 pin headers.

As far as I know, Jumper 1 and 2 should be closed, but it might be another problem, no expert in here.

Thank you so much Xavier, I did not see that there was the option :P

I am currently working on it, but when done will upload the Bank I am creating, is there a place where to share it? or just post it here on the forum.

Merci!!

PreenFM2 / [Resolved] PreenFM2 will not turn on
« Last post by kylelandstra on February 09, 2017, 01:53:49 AM »
Attached is a photo of my board.  Before I put my board in the case, I wanted to make sure everything worked first.  I then found out that it is currently not turning on through USB or wall wart.  When plugging in via USB I did not see the preenfm USB stick show up as a device which I think would nullify the issue of my screen not working.  Is anything missing that is glaringly obvious? 

The USB stick has the correct designated filepath.  All connections seem strong.  I went through the build steps again and the only thing I can think of is that the P1 and P3 must be connected.  The 330nF decoupling capacitor and the 1nF plastic capacitors all look different than in the build pictures as I got the kit from Van Daal. The 330nF has 334 printed on the side and I assumed that was ok. The Jmp3 is not connected.  Also the 5V GND and and USB square (near the 7805) are not connected.  From the FAQ it said P3 was optional and I assumed that since I had no intention of using the st-link v2 debugger, P1 would be optional as well and instructions didn't mention the 5V GND or the USB headers.  Am I wrong?  Should the preenF405/CERB40 chip have no exposed metal and completely inserted into its holder?  I can't seem to push it in completely.  Also no LED lights were connected since I am using the metal case and won't be able to see them.  So I am not sure if any of these items are required for me to be able to power the device on.  Help would be much appreciated, excited to get this synth rolling!

Hi,
You can overide dedault preset by going through the menu. Save>default>save.
Just create your empty patch before.

Yes, you can create a new bank and make your own patches from scratch, my question was about making the Initial preset "Preen mk2" clean of IM, Modulations and envelopes as I allways find myself setting everything to have it clean. I find that in one of the Banks there is already a "BLANK" preset, exactly like I would like to have it, but don't know if it's possible to set it as Initial.

Sorry if I am not explaining myself clear, I am not english native  :P

I just logged on to ask the same thing.  Initialize patch function?  Or if you use the Create Patch Bank function, will it allow you to make patches within that bank from scratch?

PreenFM2 / Custom Initial Preset
« Last post by pauto on February 06, 2017, 01:38:45 AM »
Hi, first I must say thanks to Xavier for creating this great synth, I would probably never get into FM without it.

My question is if it would be possible to modify the inital preset, as I would like to have as simple as possible to start allways from zero without any modulation or envelope.

Thanks!

PreenFM2 / Re: Yellow OLED : high frequency solution
« Last post by Xavier on February 01, 2017, 10:06:57 AM »
Just a quick question on the aluminum shield mod:  Do you just stuff the bag between the OLED screen and the PCB?  Do you secure it all?  Is it okay if the bag is touching the board?

As far as only plastic touch the board it's totally OK.
