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

preenfm2 and preenfm3 / Re: PREENFM3 CONTROL PANEL CONNECTION PROBLEM

« on: August 09, 2023, 09:32:27 AM »

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 !

@Xavier does this version include the optimizations from p3_timefx_9.bin ?

No only 2 modificaition i made.

i'm going to post the latest version in the paraphonic fx thread, so we can finalize those developments.

Sounds good

Firmware 1.01.
You can use MENU + Encoder in the mixer volume page to change other linked instruments at the same time.
"Linked" = output on same DAC.

1.01 also have a bug fix that corrupted the preset name when using with the PC/MAC editor.

That could work.
MENU + encoder would modify all instruments volume linked to the same Output pair.

Have you tried to turn on Compressor on some instruments ?
That was my first motivation to add the compressor : to control clipping.

Some FX, especially LP/HP with high resonance, can have unpredictable impact on volume.

You can

“Recall Mixer files from midi”  this could be really fun and useful. Neat idea.

You can already do that.
Toltekradiation try to find an easier method.

Today to select a mixer from midi :
Send CC#0  = 1
Send CC#32 = the mixer file number [0-127]
Then program change will load a mixer from the bank you selected with CC#32.

To go back to preset selection :
Send CC#0  = 0
Send CC#32 = the preset file number [0-127]
Then program change will load the preset from the bank you selected with CC#32.

Hi,
I had to check because i implemented that a long time ago.
"Clipping" is for the sum output before sending the data to the DAC.
So value can it can be
. "1"  - for output 1/2
. "2"  - for output 3/4
. "3" - for output 5/6
It does not mean an instrument is clipping. That can be the sum of the instruments that use this output.

Yes that's weird.
I'll take a look at the first 2 patches to see if I see something.
It's possible that some temporary variable were not recalculated is they should after some parameter changes.
Everything is reset and clean after a patch reload which is why it was back on track later on.

Your other points, recording parameters in the seq would require a change of the seq file format and a bit rewrite of how it works. It's unlikely i make some change like this in the near future.

I have another bug to report Xavier: If you lower the amount of voices an instrument can have to 0 (why is that a thing) while it's playing something, you can get the pfm3 to crash pretty reliably. I always do this by accident

0 voice is a thing, because it disable the instrument. Instruments  with 0 voice are grayed in the mixer.
No CPU is spent on free running LFO and FX for them.
If you use less than 6 instruments it's better to have the ones you don't use set to 0 voice.

Can you share a mix that crash with 0 voice (DFL.MIX) ? And let me know what you send to the instrument ?
Notes only ? CC ? NRPN ?
I just give a quick try, and no crash on my side.

The blue led on the back.
It's blinking while the engine is running.

Do you get sound after it does not respond ?
I want to make sure it's not a TFT problem.
You can also try "MENU" + "-" to reset the TFT.
I don't expect it to work, but i want to be 100% sure, it's a crash and not a TFT lock.

Next steps :
. Put it out of the box.
. Double check the soldering points (TFT, SD card, and connection to the control board on the control board AND on the main board)
Latest step :
. Send it to me, i'll take a look, and replace the main board if it's really broker.

I'm not sure what you're trying to do.
Just to get rid of the CC#0 ?

You can try to modify this part
https://github.com/Ixox/preenfm3/blob/master/firmware/Src/midi/MidiDecoder.cpp#L336

Code: [Select]

            newAction.action.param1 = bankNumber[timbres[0]];
            newAction.action.param2 = bankNumberLSB[timbres[0]];

Idea (not tried):

Code: [Select]

            if (newModeEnabled && bankNumber[timbres[0]] == 0 && bankNumberLSB[timbres[0]] == 127) {
                // Load mixer
                newAction.action.param1 = 1;
                // Load mixer from first bank only
                newAction.action.param2 = 0;               
            } else {
                newAction.action.param1 = bankNumber[timbres[0]];
                newAction.action.param2 = bankNumberLSB[timbres[0]];
            }

As written in code comment, that will only load mixxer preset from Mixer bank 1.
But you can also decide that bankNumber >= 64 is mixer and adapt the code.

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 ?

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

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

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?

Unless you flash a corrupted firmware from the SD card.

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.
