PreenFM2 / Re: custom extended firmware
« on: September 10, 2017, 09:27:50 AM »
Very nice...  :)

I think posting the binary is a good idea.
Please try to find a different firmware name : "L.07" ?

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... :D
Not at all. I don't have any idea for the moment how to include a 5th page after the 4th instrument.
I have to spend a little time on it, and regarding free time september is the worst month of the year ...

Hello Yan,

100% agreed.
It would be even better to be able to modify ALL carrier enveloppe at the same time.
And independently all modulator enveloppes at the same time.

Don't know how to do that properly in the preenfm2 control UI.

"Lock" ?
OK but you can simply turn back from 5 to 1 with the preenfm2 encoders.
Yes i like your mode to controll all channels from 1. It's usefull in many situations.

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

Thanks, that's small but very interesting inprovement and it keeps all compatibility with previous presets.
Nice :)

Having the midi channel in the combo would make much sens  :D
And Having a page after I4 dedicated to that is a good idea.

But you'll need to modify the combo file structure.
For the moment it's only 12 chars for the name + the 4 presets.

And adding a page for combo settings requires a bit of work.
I would need to dig in the code to help you more.

But i really like this idea.

Nice..   :)
I didn't try it, but if i have time to make a 2.08 it will be part of it.
Do you have the source available somewhere ?

Glad to read you could have it working for the preenfm2.  :)
I'll follow what you'll come with to make FM programming easier.

In French / Re: Son banks et DX7 ultra faible ?
« on: August 26, 2017, 03:34:03 PM »
mais c'est ennuyeux car j'entends à peine chaque son et j'ai ça pour pratiquement tout
une idée svp ?

Oops... désolé du délai.
C'est étonnant, je viens d'essayer ce son, et il le niveau n'est pas différent des autres.

Il faudrait savoir comment ton preenfm2 est cablé sur la sortie audio ?
Passer en "Mix" ne change pas grand chose sur le volume de ce son... a par le "pan" qui se retrouve 0.75.

Ma première idée est qu'il y a un problème de valeur des résistances dans le montage.
Ouvre et teste les resistances autour de l'ampli op et compare avec ici :


PreenFM2 / Re: global tune, midi-offset for presets and more...
« on: August 15, 2017, 03:21:43 PM »

Cool for the global tune !  :)

oscillator structure is definied here :
This structure is used in the global Synth param structure :
Then this global structure variable is defined at the instrument level here :
(I need to get rid of the space/tab problem, indentation is not nice in github ;) )

Adding a new parameterrowengine is not easy, it will make your memory mapping incompatible with the current presets saved on your USB.
I have this problem for a very long time so that's why convertMemoryToParam and convertParamToMemory functions are for :)

I'm away from home for a couple of weeks still so i cannot try anything.

The suggestion from SirPrimalform in the first message of this thread sounds good to me.
Here are some clues.

I don't think you need new variables.
Add a new Constant here :

Modify SynthState.cpp
To add your UI string for this new "Frequency type" value.
Line 204 replace OSC_FT_FIXE by the new constat you added in SynthState.h.

At this point the value should show up in the UI.

Modify Osc.cpp and add a "case" in the switch to calculate your frequecy when the new Ftype is selected.
Use the variable detune for your Hertz detune calculation.

I don't think you need to modify FMDIsplay.cpp but you can search for "OSC_FT_" and see there are some hack there to have the display show/hide ftune depending on FType.

Make sense ?

this is an old topic, but i would like to see this implemented as well!

I don't have any plan to implement this.
But Lokki, now you know where the change would be  ;)

Ftype menu is defined here :

Every operator has its own enveloppe that can be set. See part 2 here :
