There are several methods.

I am not sure where you "are" with your Preenfm2. Is is already running and you
want to upgrade the firmware? Or have you built one and need to flash for the first time?

If your synth is already running, then the easiest method is probably to boot into the bootloader and enable mass storage device mode, so that you can access your usb-stick via the broken out usb port. Then you can simply copy the firmware to the root directory of the stick and update it directly on the Preenfm2.

The docs for this should be pretty clear. You can also put your Preenfm2 into DFU mode and update via terminal with the dfu-util program.

Cool!

Funny, the PD bug was only on Linux, it worked all the time on OSX...

Did you press the top left button (near to the display) this will load the bootloader screen...

on the desktop version the usb-stick is inside the case. you can put the preenfm2 into "mass storage mode" to gain access to the stick if connected via usb to your computer (via the usb-port at the back)

can i send you a puredata patch to test? (do you still have it installed?)

i am looking at your setMatrixChannelPressureSource function and can't see anything wrong. hmm.

you are right, i am wrong. i looked at the PureData implementation, where pressure is the first inlet, but looking at my controller code for teensy it becomes clear that indeed pressure is the second argument sent. hmm, so why does it not work. will try to find out :-)

how did you test?

i only took a quick look at the code (the poly handling) so might be totally off, but:

you have:

Code: [Select]
this->synth->getTimbre(timbres[tk])->setMatrixChannelPressureSource(midiEvent.value[0], INV127 * midiEvent.value[1]);
value[0] is the poly_at value and value[1] is the note it is associated with. with the channel pressure code as reference, did you maybe switch value[0] and value[1]?

it just is not reacting to poly aftertouch if i set it in the mod matrix. i get no modulation. setting the same modulation to channel pressure it works.

how did you test? with puredata? i tested with puredata as well, and it is not working here.
will try again with my actual controller. the poly at is always bound to a specific note, so you have to take care of this in code as well, but i guess you are aware of that.

hmm, i don't know of any soft-keyboard that has poly-touch emulation.

is your preenfm3 also always visible when in DFU mode?

I saw poly at in the mod matrix on 0.100z, but it does not work yet. should it? happy to test further in case it is needed...

I know I know. Still for clock DIN midi is better then usb, since a unsteady clock (caused by the 1ms polling) can mess with arps etc.

that aside, I am very happy the preenfm3 works over usb now and that it was such an easy fix! Thx.

DIN midi has a baudrate of 31250, true. But USB midi can run at up to 480mb (usb 2) and some newer synths and controllers use that! If you have lots of modulation that can make a big difference. Usb 1 is also not very tight, given it has a polling interval (at least 1ms I believe) and hence midi clock is not very precise from usb...

What is really strange about all this, is that it still sometimes worked before, so the code was only partially broken? or variable ordering is dynamic even after compile time? puzzling...

btw, teensy 4 use a similar chip, no? they use usb2 for midi communication, maybe that would be more reliable with -O3
