preenfm2 and preenfm3 / Re: Flashing bootloader on F405
« on: October 18, 2017, 03:24:26 PM »
Hi,

I copy and past your command and see that the "x" character you use in the adress is wrong.
It should be the regular lower case x letter.
In the USB id too !

Definitely  ;)
Hertz mode and global midi channel are part of 2.08.
I just uploaded a beta 1.

I've just uploaded a 2.08 beta 1 firmware. See first message of this thread.
It's beta because it may contain bugs, if you find one, please report.
Thanks  :)

Hi,
That requires a good amount of work because there are parts coded specialy for the preenfm2 hardware (USB, LCD, STM32F4 interuptions).
But it's C++ so yes the main FM engine can be compiled on any platform.

this resulted in a crash of the synth.

Do you have a step to reproduce ?

1071
Cool thanks for testing.
No problem with saving combos ?  :)

the timbre numbers 5 to 8 are displayed on the "home" screen as 1 to 4. so if you play i1 and i5 you only see that i5 is playing. theoretically there would be space one row below. this is not a real bug, more cosmetics :-)

Yes i know that.
But on the next line, there will be problem with modulation "Note1 Midi Scaling" and with the blinking midi clock.

The branch name is 8mono if you want to play with it.
https://github.com/Ixox/preenfm2/blob/8mono/src/hardware/FMDisplay.cpp#L1121
And the function bellow that erase the number after some time.

And if you need to burn the bootloader itself, the doc is here :

Thanks for the pictures
And glad to read it now works....

Midi channels are still in Menu=>Settings, but i have a proto with 8 timbres.
Let me know if you find any bugs.
I also didn't test it under heavy load.

Screen displays "8 timbres" when booting with the version 2.07 b1.

I tested quickly the combo : load and save the default and the bank ones.
Names are different for this "8 timbres firmware"  combo : extension is .cm8
so it should not erase you previous .cmb of.
But you'd better save your USB drive if you have important preset/combo on it.

You'll have no combo banks ready when first booting so you'll have to create at least one : go to Menu>Tools>Crea>Combo.

Hi,

Pusherman group ?  ;)
I have no idea how you solder the STM32F4... Congrats.
Would you post a picture of the preenF405 ?

To bad for the RX pins.
Sorry, I'm not aware of a tool that test connected pins.

You could configure the RX as a GPIO (remove the USART part).
https://github.com/Ixox/preenfm2/blob/master/src/PreenFM_init.c#L42
(I havent' looked at this part for a very long time....)
Read the value and display something when state changes.

Right, pull should copy the preset from the preenfm2 to the editor.
Push do the oposite.
(Software point of view)

Check Menu Options=>Midi settings as well as the midi channel if it does not work properly.

Keeping the same polyphony would be difficult as more timbre adds more FX processing (1 per timbre) as well as more mix processing and more memory usage.

But that sounds doable if your reduce the polyphony.
The combo file format would have to be enhanced.

Sounds like a good project for anyone who wants to dig into the code  ;)

preenfm2 and preenfm3 / Re: plugged wrong power supply in my preenfm2...
« on: September 26, 2017, 08:59:48 PM »
Many 9V power supplies have a higher voltage, specially when no current is provided (multimeter test).
2 or 3 seconds ? That should not be a problem. The 7805 voltage regulator must have turn hot, but that's all.

The OLED is yellow because the preenfm2 draws all the squares. Else it would be all black. So it kind of work.

You should verify the USB key.
The preenfm2 CPU seems to have problem reading it.

preenfm2 and preenfm3 / Re: Multi USB inputs..
« on: September 24, 2017, 07:10:03 PM »
support for usb-midi devices would be very nice indeed. Xavier, is this much work?

Oh yes !
USB OTG (switch between host and device) is very complicated.
In fact USB is complicated, which is why it's so simple to use.

preenfm2 and preenfm3 / Re: arpgeggiator toggle, waveform .txt?
« on: September 16, 2017, 11:45:47 AM »
Hi,

No arpeggiator toggle. You have to turn the encoder "Arpeggiator>Clk" To "Off".
If your keyboard has some programmable button you can send a NRPN message (0,28) to 0.

Some users had some success using Audacity to turn wav file into preenfm2 format :

There are some examples here :
