preenfm2 and preenfm3 / Re: Can't flash PFM3 on Windows 11 via Chrome or WSL dfu-util

If the 0.105 does not work, can you with this firmware measure the Led pin when the preenfm3 is on and the screen is black :
Led pin Should be 3.3v.

preenfm2 and preenfm3 / Re: add matrix destinations
« Last post by Toltekradiation on October 23, 2021, 01:06:51 PM »
hello,
i had a go at adding the filter param2 to the modulation matrix.
Done it for the pfm3 as it's much easier to develop for.
I did it for all filters but the BP, which need too much processing.
The cpu footprint should be ok for the others, so here is a .bin if you want to check it out.

For @Xavier, i did a PR in github, to make modifications easier to read :

I’m not with the PFM3 right now, so I can’t check for sure… but it seems like there’s no activity from the TFT at power-up. No flicker/flash, no dark pixels… it appears exactly the same as when there’s no power, until I reset the CPU — then it clearly turns on, and a split second later I see the text on the display.

As for firmware 105, this is what the PFM3 came with and the TFT didn’t turn on then either (until reset CPU). But that was with the previous TFT with weird SD traces. So I will revert from 108 to 105 on Monday and see what happens with the new TFT. I suspect it won’t make any difference.

Anyway, tell me if you have any other idea just in case 105 doesn’t work either. Thanks and have a nice weekend :)

Thanks, i share your point of view. 
Having a builting reverb is very nice.  :)

Thanks for the update.

First time i hear about this problem.  ???

The TFT led is controlled by a PWM to allow adjusting the brightness.
Can you confirm the TFT is totally black ? No led at all.
Or do you see the screen turning a bit bright without anything on it ?

Can you try firmware 1.05   ?
https://github.com/Ixox/preenfm3/releases/tag/v0.105
This version does not have the brightness control and just turn on the led.
Does this firmware make a difference ?

You don't event have the preenfm3, PCB is on its way to you.
When you receive it, please ship it back to me. I'll reimburse you of course.

Thread Locked.


UPDATE : preenfm3 + shipping totally refund to solipsvs although i don't have it back.

you people tell me what my big crime is?  how was i offensive?  and then you can just fuck off.  is the complaint that i am ’often’ offensive?  so tell me what was offensive here and then you can piss off!  and shove your synth up your ass!  seriously i dont give a fuck about your feelings!  and i know you want to sell more, given the state of employment and inflation and politics so shove that up your ass too!  you dont understand me?. well understand that.  stay stuck in the past, i dont fucking care honestly. i dont need your piece of shit synth!

and im not surprised you dont get it.  you dont get much and im always stuck explaining shit to you.  so be old and lame, stuck in the 90s with your dx clone with half stepping features that belong in the last century!  turn on steve windwood and call it a day.

when was the last time you did any sound design?  never.  thats why its not important to you and why you dont see anything as a game changer.  any real game changer would be way too much for you, this is just a game changer with training wheels.  but you dont need it, and wont ever use it so the point is moot!  youll never get any closer to needing detailed feature on your noisemaker, because you never design anything of consequence and you wont begin anytime soon.

yall sure make the case for pasty nerd in basement with synth needs way to get back at the world who forced him down there in earlier life lol

EDIT: x-posting with Xavier...

i don't need a thicker skin, or at least i don't think so.

also, i am not offended at all by your comments, it is just funny to read them and it seems to be a strange way to get where you want. but if it works for you...

you are right though, who am i to tell you that i think you are "offending" Xavier. he can surely speak for himself.

glad you like your preenfm3, i haven't used mine much lately but will again.

Yes solipsvs, you're rough (rude ?). And yes i do care.
That decrease the fun i can have developing the preenfm during my free time.
And i don't care about the number of preenfm sold. It's really OK as it is.

That being said, I don't think this feature is a "game changer".
Sounds like a small addition to me.
As you can see in the code :
https://github.com/Ixox/preenfm3/blob/master/firmware/Src/synth/Env.h#L73
Some part of the envelopes are already curved. (Decay, sustain, release are not linear).
I was surprised when i did that how small the impact was. (The preenfm1 was all linear)

If you modulate the modulation indices in the matrix, that has the same impact as modifying the envelope of the above operator.
And modulations indices are available independantly as targets in the matrix .
Possibilities are high.

If you really need something more flexible for the enveloppe, the firmware is open source. That's the point of the preenfm.
I would be happy to help implementing specific features for custom firmwares.
You can maintain your own development firmware and i will maintain mine.

lets get something straight, i choose PreenFM3 and i have voted with my money, my time and my interest.  i would like to use it further the way i use my gear and ill make a comment in promotion of ideas i have.  if that upsets you, well, its not my fault.  i dont see anyone else speaking up.  why not?  sometimes those extra functions make something easy to work with which is what does it for the lasting reputation of a favorite synth.  synths that are intuitive and meet the user most of the way just speak for themselves and there are too many that just dont go the distance.

i wouldnt say anything if i didnt care as the saying goes
