ok, original post updated... is this different enough?

This is great news, I'll check it out as soon as I can!

Just took a glimpse at the changes, and I am very happy to have a reference for future fiddling with UI code (hope I find some time for that), thanks for that!

just be aware that you cannot simply add more ui elements to the preenfm2. you will have to change the preset file as well and make sure that old presets are loaded correctly and new presets are loaded correctly on older firmwares. it is a little messy. what i did involved no changes to the ui as such, i simply expanded a menu entry and used the same variables, that way the preset files stays the same.

PreenFM2 / custom extended firmware

hi there,

i am hacking the firmware quite a bit lately and have made a github fork to save my work.

find it here if you are interested:

the changes as of now are:

*hertz mode: in the oscillator settings, changes detune to hertz increment instead of cent, beating stays the same over whole range of the instrument.

*global midi channel: if enabled midi coming in to this channel will be sent to all four channels. useful for mpe instruments mainly.

*program change modes: enhances the program change options in the settings, off and cc are the old no and yes, bank combo and dx7a and b ignore banknumber messages and switch the choosen mode via program change. (banknumber lsb cc32 can still be used to choose bank number)

*usercc: set a cc number in the global menu (anything from 0 to 126) and choose that as a matrix source. be aware that there are many cc's taken for other things on the preenfm2, so best to check first if your desired cc is free.

i will try to keep this post updated with the latest info, and hope to continue to work a little on the firmware.

EDIT:xavier, i'm not sure if i should post a binary here in the forum, what do you think?

firmware is attached

ok, well so i hope this september goes over VERY quickly!  8) ;D

have a good time

I'll have to work seriously on a 2.08.
Don't know when though  :-\

ok, xavier, i'm getting impatient, haha...

do you have any suggestion where i could start? maybe adding the menu entries in the instrument selector menu? i could not find it in the "normal" ui, but i probably did not look close enough...

haha, lock is a strong word yes.  ;D

of course you can get back on track with the encoders :-)

i will push the global channel thing to my GitHub as well...

as i said i will be very happy to help you out when you have time to start working on 2.08

one potential problem with this setup is, that you can "lock" yourself out of the preenfm. say you change from a combo with channel 1 2 3 4 to a combo with channel 5 6 7 8 via program change on channel 1. you can then not change back on channel one, but you have to change to channel 5 to get back. a solution would be to have a global midi channel for program change etc. (i did a simple mod already that does this, although it does not filter any messages out)

i think i figured it out, find the changed repo here:

sure, i still have not figured out how to use GitHub correctly, i tried to fork your project and then tried to merge my changes but somehow it always says it is already in sync... but maybe i can upload the code like this to GitHub (but then you will have to go through the changes manually)

hi xavier,

thanks for thinking about it.

it would be just super great if you (and maybe i can help a little) can make this happen. this would open up the possibilites a lot. if you can also add the transpose offset in the combo page as well that would be killer. but i guess if you have to add a page anyhow adding another parameter would not be that much of work.

may i also suggest, that the combo presets gets saved with a few empty parameters as well? that way if there is stuff to add later, the file structure does not change. maybe that would be a good idea for general presets as well, but there the "mess" is already there :-)

thanks for looking into this, great and very appreciated.

PreenFM2 / midi offset etc, combo mode idea
« on: August 21, 2017, 02:41:47 PM »

i started implementing the midi offset or transpose (-24 to 24) and added a parameter row etc. it all shows up in the menu but is not yet working. anyways, this solution seems rather hacky, because transpose should really not be saved in a preset. i also had ideas to add a random small detune to each played note, to make it sound more "natural", that should also not belong to a preset...

i thought about it and came to the conclusion that it would be great to have these kind of settings saved in the combo file.
as i understand it is merely a container for four presets. there is no additional things saved, right?

my proposal would be:

on pressing the instrument button, you cycle through the 4 instruments and when you arrive at instrument 4 an additional press would bring up the combo settings menu.

these settings would then be saved and recalled with the combo.

settings that i would include (in order of importance)

-midi channel for each loaded instrument
-transpose in halftones (-24 to 24)
-random detune

this would make the 4 midi channels in the global menu obsolete. but it would not change the preset system of the preenfm2.

would something along those lines be feasible??

i'm very happy to help, although i would need some guidance, as you have figured out already i think...(but i'm starting to see the light :-))

nice, looks good! how easily is it adoptable? (i.e. write your own editor for say a waldorf microwave) or for a custom preenfm2 firmware... :-)

there you go. did the mod on the stock firmware in the train, so i could not test, but it compiles, so should be fine...

let me know

i have a firmware with some other changes here, will make one with only the hertz change in the next days...

cool, i did it! it works, and it sounds nice.... i had to widen the detune range to -9.99 to 9.99 but that has no side effects i think.

i can share a compiled firmware if somebody is interested.

xavier, why is detune hidden when ftype is fixed but it still affects the fixed frequency in the osc.cpp?
