preenfm2 and preenfm3 / Re: PFM3: Stuck pixel artifacts around text

« on: May 11, 2023, 03:08:04 PM »

I really just twisted the knob. I can take literally any of these values and bump them up to seemingly infinity.

I want to mention again, that I am not using the latest release but a build from the current codebase. maybe something changed there

The value stays like that if I save and reload the preset.

I just set the sustain value to 1.0, but I still get the same effect. Are there more values which should have a limit?


Edit: Just tried setting all of them to 1, but no luck.

Edit 2: You know, what, just try it for yourself: https://chonkyrabbit.eu/files/_share/EXPERIMS.BNK
The first "sound" is the kick with the env values freely going, and the second "sound" is that same kick with the env values limited to 1. All the weird envelopes are in OP2

Edit 3: It must be related to the values somehow. Maybe 1 is just too much as well, and only 0.99 works. No idea, I've been avoiding high numbers and had no issues so far, but maybe that is just a fluke

No user envelopes for me.

Value/Level
Attack: 0.96/0.1
Decay: 3.13/1
Sustain: 2.36/1.8
Release: 1.89/0

All curves are linear

Edit: Display was garbled. Edited the values, sorry.

Hey, thanks for your reply.

I already saw the github documentation, but most of the menus and abbreviations are still down to my own exploration, which is pretty hindering.

The only thing I know about how to reproduce this issue is when editing a value via an encoder in the Instrument editor. I can't quite put my finger on it, but I can only remember this happening in the Envelope editor screen. The value turns yellow, signaling  that it had been edited, but after a few minutes of usage (anywhere) editing something in that menu causes pixels to start getting stuck. They start accumulating on a two pixel high bar at the top and bottom of the text area, but at random places.  Continuing to edit that value increases the amount of broken pixels and spreads them over the whole text block (weirdly not the text itself). The amount of corruption dictates, how much will be corrupted on other pages.

I will share a video later, this is too hard to explain

Edit: Here is a video, sorry, I had no better camera at hand: https://chonkyrabbit.eu/files/_share/issue.mp4
I want to mention, that this yet again only happened in the ENV menu.

Edit 2: I just managed to create a patch, which pretty much immediately causes this bug to occur when viewing the ENV settings of a specific operator. LMK if you want it.

preenfm2 and preenfm3 / [Fixed] PFM3: Stuck pixel artifacts around text

« on: May 08, 2023, 04:38:05 PM »

Hey there,
My PFM3 just arrived today, and I'm really excited to use it more, but there is one issue that prevents me from doing so right now: After using the synth for a few minutes, updating pixels start getting stuck on yellow. Once this starts happening, more and more pixels do the same thing, until text is barely legible. Interestingly, the pixels are only stuck in specific screens, but always around text, or where text could be.
I tried to change the TFT reinit setting to Auto, but whatever that does, it does not change anything.
Is there a way to fix this or at least work around it?

Also are there any plans for a thorough manual or usage video? I'm kinda (very) lost in the menu system.

Thanks!

Edit: The bug must be somewhere around here: https://github.com/Ixox/preenfm3/blob/40caf9b069527f135fbab60e07c481d0f88e5171/lib/Src/TftDisplay.cpp#L910
I sadly can't find out, how and where TFTActions are used, maybe because the github search is trash. I can only assume that there is an issue with the way that the TFTActions are handled. I assume, that there is some kind of cache that tries to reduce the updates, but in this case corrupts pixels in a box around any piece of text. What is even weirder is the fact that it just happens over time. The corruption starts, and more pixels just get added on top of the existing error, as if some buffer was not cleared after use...

Edit 2: I'm on firmware 996, but I also tried 999 (the effects build from that one thread).

Edit 3: I finally found where the tftactions are used: https://github.com/Ixox/preenfm3/blob/40caf9b069527f135fbab60e07c481d0f88e5171/lib/Src/TftDisplay.cpp#L357
How does this work? I can barely understand what's going on... My first guess would be, that the tftmemory is faulty, but only around text? (I did notice some glitching in the env curve editor as well, but I could only notice some at the very top of the box

Edit 4: I think I found something. The only case where "setDirtyArea" is used is whenever a character is written. Could someone build that but with "tftDirtyBits = TFT_PART_ALL_BITS;" instead of setDirtyArea?

Edit 5: Would this even work or would I end up with a screen that then only contains the updated text and nothing else?

I'm in the exact same situation as you. Barely an demos, let alone just jams with the PFM3. Funnily I also own a Keystep Pro xD

Bought one anyways, which will arrive in one week. I'm so excited!

Well I did in fact understand that. I was just hoping that it was somehow possible to ignore the switches inside the sockets. Thinking of it, it would probably not be possible on a hardware level, without changing how the device is connected internally

That cleared up a lot, thank you!

One more thing: I noticed, that all jack sockets have contacts for a TRS jack. Would it be possible to output a stereo signal by outputting the mono signal to both available contacts?

PreenFM3s are back in stock as of today. The price only has increased by 10€ which is less than I expected

oh well that's good to know (The documentation is a bit weird imo. Hardware information is among the build instructions for whatever reason)

Now I'm wondering; Are the timbres stereo? I thought each timbre would get a stereo output, but why am I being told (in another forum and kinda in the documentation) that there are six mono outs? Even the jack sockets are stereo.

I do need a mixer regardless though, that's why I'm asking how it's volume behaves with a 10k resistor.

Edit: I understand the output config now. Found it in the wiki. Yet again in a completely different place. Man this needs a rework

« on: April 10, 2023, 12:25:07 PM »

Hey there,

I'm planning to get a PreenFM3 once they come back in stock on Van-Daal. Since it has six stereo outputs, I need to get a new way to mix that together and thought of a passive mixer (because it's cheap)

Does anyone know how severe the volume drop is with a 10k resistor on both channels? I'm wondering, if it is even worth dealing with the hassle of building one if the synth is way too silent afterwards.

Regards

I contacted Van Daal yesterday and they told me that PreenFM3s would be back in Stock within one month. Prices would increase a bit though. By how much, they haven't told me.

Hey, I'm thinking about getting one. Could you please shoot me an email?

Edit: I did not buy it. You can still have a go at it.
