sorry, i only looked at the 0.91 release, and it didn't contain the sdcard zip file...found it in the 0.90 folder.

it seems i am missing some fundamental stuff :-) 
will copy the folder to the sdcard (did not know i had to do that) the wiki does not mention it, no?
i guess i have to look at the zip file.

sorry, yes i realised the "x" thing after a while as well, had no time to post it yet.
this is the link to the display:
https://www.aliexpress.com/item/4001135326039.html?spm=a2g0s.9042311.0.0.27424c4dP0cOvE
the sd pins seem to align, no?
is there anything more verbose in regard to the sdcard that i could try?

preenfm2 and preenfm3 / [fixed in 0.95 ?] preenfm3 sd card error
« on: October 18, 2020, 09:37:54 AM »
hi xavier,
i flashed the firmware successfully.
unfortunately my LCD was a different kind of pcb, but still 2.8''. the holes for the sdcard-reader don't align. i bent some headers and soldered it, but maybe something is wrong...it is also possible the reader does not work on the PCB, it is a cheap chinese LCD. the screen itself works flawless.
now,
-when i boot up without an sdcard inserted i get a: SD CARD ERROR after which the preenfm3 boots successfully.
-when i insert a sdcard at boot up, the screen just stays black. if i then unplug the sdcard, the screen goes white
-when i insert a sdcard after boot up the screen goes black. when i remove it the screen goes white.
does that indicate anything?
if i would attach a separate sdcard reader module, i need the four connections and 3.3v and gnd?

i think "commercial" synths usually just fade out the current sound and then load the new one.
the absolute golden way would be a crossfade (with adjustable time) between one preset and the other :-) some kind of morph function.
but that is probably too advanced for a simple program change.
i think just fading out the current sound (3ms) will greatly help with the clicking. or you can delay the patch switching until you hit the next zero crossing of the waveform currently playing. of course this will get very adventurous with a combo of 4 or 6 instruments :-)
another point to consider, what do you do with currently playing midi notes? simply stop them? change the sound and keep them playing? only load the new sound, once you get a note off?
actually the option to keep voices/instruments sounding until you get a note off would be very nice, but again this essentially means you have to load the new sound and keep the old sound in memory...

ok, just to clarify...
those mixer settings can also be recalled by program change messages for example? so that i can recall different sounds/combos with different volumes?
cheers

hi xavier,
from looking at the pictures of the preenfm3 and the BOM it seems there is no "analog" volume control anymore, right?
you wrote about a mixer that you implemented. will master volume be a value to be saved in a preset as well? that would be great. (so a combo sound would store both individual volumes and the master volume)

maybe not the answer you are looking for, but i have made a custom extended firmware, where you can choose in the global menu what incoming program messages should do, change banks/combos etc. maybe that would be an option? you find it in the custom extended firmware thread...

preenfm2 and preenfm3 / Re: dfu mode linux error
« on: May 29, 2018, 01:00:13 PM »
i solved it by removing the usb-stick (pain in the a**) because you have to open the case. i then uploaded the new firmware directly to the stick (usb-stick mode in bootloader was also not working)
after reinserting the stick i got a "bootloader ok, but no firmware installed" screen and i was able to boot to bootloader and flash the new firmware. now i am again able to flash via dfu mode...
this seems odd and weird.
