PreenFM2 / Re: [Resolved in 2.05B4] Pitchbend response?
« on: July 18, 2020, 11:42:48 AM »

Make sure you use "O*Fh" and not "O*Fq" with the latest firmware.
The first one should apply a "symetrical tone pitch bend".

If you still have a problem, please try to explain that clearly.
What do you use ?
What you are doing + settings ?
What is the behaviour and what would be your expected behaviour ?

With the builtin bootloader, you cannot do anything wrong, you'll always be able to flash again.
The bin file you want is : p2_2.11o
You don't need the cmd files if you flash from the bootloader.

But don't hesitate to flash the BETA :

If the screen is full of squares after the leds flashed, then the problem comes from the USB Stick. It's flashed.
You can check by hodling down a button while powering on you preenfm2. It should enter bootloader mode.

To flash it if needed :
Or there are recent tools to flash using DFU on st webstite.

I guess an updated Editor that reflects these change will come when out of beta? because this won't work with the latest editor i reckon?

Unless i miss something, the only modification needed by the editor is the second matrix destiation.
I have to modify the editor before releasing an official 2.12.
But don't hold your breath ;)

But it seems like I stumbled across a bug when selecting banks/patches in the DX7 section. If I do accidently select patch Nr. 33 then the PreenFM2 freezes on playing the current waveform and needs to be restarted for recovery (my sequencer starts numbering patches at Nr. 1, so this is exactly one patch above the allowed range for DX-7 banks -- just for clarification. This looks like a missing range-check leading to out-of-bounds memory-access at a first glance.).

Nice catch.
Thanks, it's fixed for next version.

2.12 Beta 2
See first message of this thread for details.

SMF can you give a try to firmware 2.12 B2 i just uploaded. You posted the good day when i have some free time :)

Toltekradiation, Beta 2 should contain your 3 fixes.  Thanks  :)

Thanks, that makes total sense.

CC7 would copy CC73 i agree, that's easy to do.
Keep in mind that's a digital volume, when decreasing it reduces the number of bits used by the DAC. So keep it at 1.0 for regular use.

For CC10, I see, that's the reason i created the "Mix" Filter (that's the first one) and its "Pan" parameter, but when using it you cannot use any other effect.
It would have to be a feature available through CC only as i don't find any nice place to put that in the already crowded UI.

@Drexy No release with the fix yet... I don't have any excuse except the lack of time.


I use the PreenFM2 quite a lot for my music. A real annoyance is that it does not have channel-volume and channel-pan. (At least not on the standard-CCs) So I have to use filter-gain or the CCs for the mixer to achieve the desired changes. While this is nice if you want to alter the sound and stereo-seperation completely, this is totally annoying if you just want a fade-in and/or fade-out.

So, please, make these midi-CCs (Channel-Volume/-Pan) work, before adding more filters or other more CPU-intense but seldomly used things.

all the best and TIA!

I'm not sure i get it.
Why doesn't the MixerGain (CC73) work for fade-in and fade-out ? It's available even when no filter is selected.

And can you clarify what you mean or want to achieve with "stereo-separation" ?

PreenFM2 / Re: Audio Output from SMD version
« on: June 07, 2020, 07:59:14 PM »
The person who made the SMD version did actually make a thread on this forum.

If i followed correctly, No, it's a different one.
The SMD thread here was very interesting, the guy designed something new with 2 MCU and lots of changes.
It was very interesting and it's very well documented on his site.

And that's not the case at all of the SMD version you can buy online which is a copy of the existing PCB.
But it's not forbiden, it's just not very fair.

PreenFM2 / Re: Sequencer as modulation source
« on: June 07, 2020, 09:39:36 AM »

Yes they can.
I suggest you to have a look at part 3 of the manual ;)
(In firmware  2.12 they are 2 destinations slots per row)

I just ordered a SMD version before looking at this forum, is the SMD version bad? did I make a mistake?


I'm not aware at all of these SMD versions, the author never contacted me for anything.
I really think that half the fun of the preenfm2 is to build it yourself.


PreenFM2 / Re: Exponential Envelope Option?
« on: June 03, 2020, 09:49:11 PM »
There is a bright "clickiness" to every note on the DX that is not present on the Preen. You can even get it when you turn all the EG levels on a DX to 0 but leave the attack EG level at 99. A lot of the time, sound designers will add a little attack time to get rid of the sound where it's not appropriate -- but percussion sounds often utilize it to their advantage.

I noticed that. The "clickiness" attack of the DX.
I don't say it's impossible but I would be surprised if that came from the exponential attack.

Hi please implement this!
I'm on the fence about buying one and this issue is really the deal breaker

That made me smile :)

You know it's open source right ?
I will be more convinced by hearing it than by 2 posts and an email ;)
And how it's done makes this very easy to do (see Toltekradiation link in message #2 above)
For the final version It would need to be behind a menu option because it will change the existing patch sound.

PreenFM2 / Re: Feature request: init patch
« on: June 01, 2020, 08:02:45 AM »

Yes good idea, but I don't know how to add that in the menu.

Workaround :
What you can do is to create a bank ("A_Init") with first letters so that it shows first in the bank list.
Then in this bank a "Init" preset where you put the one you want as Init.
You can then find it and load it easily.

Yes, but i think what he meant was for the attack which would require an exponential in the opposite direction.
I have no idea whether it would really impact the sound.

For the moment attack is linear.
