Hi Patrice,

I finally have a PR ready for all your changes.
I squash all your commit into a single one.
https://github.com/Ixox/preenfm3/pull/46
I hope i didn't mix up anything.
Can you take a look and also please summarize what this patch contains ?  gra1 and gra2 ? + other adjusment fix ?

I noticed some high volume noise when browsing the FX type and when i arrive on "Bode".
That happens from time to time.
Is there a solution to get rid of this ?

Thanks again for you work

@Xavier, these mods are pushed to the current pull request as well.

OK thanks a lot for continuously improving your effects ! 
And thanks for the PR.

Yes I'll make a release with your latest patch. Very soon !
I should have more free time than the previous month.

Hi,

You should be able to get rid of the pop when you retrigger the sound.
Look at the attack and release. Make sure the relase level is 0 at the end.

Have you tried to copy your sound to 2 or more instruments, and use the sequencer in really low BPM, you can try shift the start of the different instruments so that the "attack" is hidden by the others that are still playing.

Hello today I notice that when the preenfm3 have a noise background problem. When the unit it’s connect send a noise not super loud but enough for disturb a clean recording. Happend to anyone? Have a solution?

Hi,
Is it powered by USB ?
USB wall charger can be very noisy.

« on: August 29, 2023, 09:34:42 PM »

Oh OK

No there's no such page.
There's no "level operator" in the preenfm.

Modulation use MI (modulation index).
You have a page with all MI values (modulation index).
=> A same modulator operator can have to different MI to 2 different lower operator : see algo 1.
You have 3=>2 and 3=>1.

And you have a page with MIX level for carrier operator.

They're both in 2 different pages.
The number of MI and carrier op levels depends on the algo, so it's not very straightforward to have such a page.
It's not a 6 level to 6 knob simple mapping.

Preenfm3 here. Is there any operator mixer that I dont know of? I can change the levels at the level page but single knob for all the adsr would be wonderful.
Thank you!

You can hold down menu while turning encoders for enveloppe
It will change all operators of same type at the same time (carrier / modulator).
(Value will be green instead of yellow when modified to show other values are modified at the same time.)

You can also use Long press "-" to copy ADSR value, and then long press "+" to paste in an other operator.

preenfm2 and preenfm3 / Re: PREENFM3 CONTROL PANEL CONNECTION PROBLEM

« on: August 26, 2023, 02:23:53 PM »

Yes it was LOAD connector and now works perfect!! After hours of headbanging that first crystal clear sound is priceless!!! 🕺😄

Everything works perfect, midi din as well, the only remaining issue is the midi clock light, all lfos arp and seq are set to ext and the unit receives clock (* blinks) but no blue led blinking (neither at startup)😄. What could be the problem?

I'm back home.
I'm so happy to read this  Congrats for the fix !!

So you're talking about the LED on the control board ?
It's a direct wire to the main board than to the CPU.
It's labelled simply "led" on both main board and control board.
But if everything else is working, i would NOT focus on that one, it's not very usefull !

I had a look at the video/pictures.

The SEQ button things does not make any sens for the firmware.
So it's a hardware problem.
As if pushing the SEQ button sometimes allow the contact to be good.

The fact the sometimes the preenfm3 takes time to start can also mean that the GND can be wrong and the MCU (STM32) cannot get a clean clock that allows it to start.

Did you solder totally the control board to the main board ?
Would be interesting to see if you have the delay in starting when you turn on without the control board.

Oh two other things I noticed just now:
1. The USB-MIDI option in the settings is ignored. UM works even if disabled
2. It would be nice if the PFM also sent all the received UM data out its corresponding MIDI port. I don't own a UM interface and was hoping I could use the PFM for that

1. Needs a reboot. It should work. (Cannot confirm 100% before i'm back home)
2. I tried that already, but the problem is that the UM is much faster then Midi jack. so between UM + midi send from the controller change, that's too much to handle for the midi jack.

Edit: I have also noticed some more issues:
1. The PFM crashing while accidentally turning down the voices to 0 is still a thing. I think it might be related to doing that while release is still going
2. Simultaneously playing notes over MIDI and UM causes stuck notes on the instrument voice controlled via MIDI, but the stuck notes are taken from the UM side

1. Will take a look when i'm back. Thanks.
2. Yes i'm not surprised. That's 2 different execution threads, so result can be corrupted if a MidiUsb arrives in the middle of a MidiJack command. I think it should work if Usb and Jack midi targets different Midi channel.

OK It was quick, i had the DFU generator on my laptop, but i cannot try the dfu file.
Let me know if the DFU file here works for you
https://github.com/Ixox/preenfm3/releases/tag/v1.00
Thanks

2 additional things :
. Puting the firmware on the SD card is useless. Only used if you want to flash it again.
. the blue led on the control board only blinks with Midi CLOCK input (not any other midi activity only CLOCK).

Now reading this from another tread:

"New PCB (1.6-100) only works with firmware 0.109 and newer.
As written in firmware 0.109 : "With these new PCBs, the knobs and butons won't respond with earlier firmware."

Could you compile the DFU file for the latest firmware? Only Dfuse works for me.

Oh yes, i totally forgot about this possibility.
But all mainboard are shipped flashed with latest firmware, i don't know why you needed to flash it.
Anyway...
I only have a laptop where i am. Will try to create a DFU file.

Hi,
A quick note.
Between my vacations and a following travel for my Job, i won't be at home before september.
I'll release then a firmware with the PR and bug fixes.
Thanks

Hi,

Yes looks like some soldering problems.
If does not work 99% of the time, that means it works 1% of the time.

When you check the 5v on the 74HC165, where do you take the GND ? On the control board too ?
I ask this because it can be a problem with GND on the control board.

Or maybe a shortcut between the 3 Data pins between the control board and the main board.

The DFU built in button on the main board must be hold down when turning on the preenfm.
Then it enterrs CPU DFU mode, so the screen remains black. And DFU can be seen from a computer and a USB cable with a DFU capable software.

On the control board, the blue led will blink when the preenfm2 receves midi Clock from external midi.

Thanks for sharing.
It's quite busy at work this week, but i had a listen to the PERCUSSION bank.
They sound good and those kind of sound are not easy to create 
Nice !
