preenfm3 : v1.03 (Toltekradiation/pvig : "vosim" algos + CC + fix)

[JeffS]

thanks Lokki for the clarification, and Xavier for the tip on Keyboard vs. Continuous. I think that solves it, as I wrote on the other thread a moment ago [the slots 5 and 6 thread]. I will check with keyboard later!

[lokki]

if it works with max/msp but not a midi keyboard this could be an issue with midi handling of DIN vs usb i guess. but i think those streams should be merged much "earlier" on in the code...

[JeffS]

Sure enough, just hooked up my keyboard and Continuous is the way to get it to work like the other synths I'm used to. Sorry for the false alarm!

  No problem ! Glad you found what you need.

Firmware v0.98
https://github.com/Ixox/preenfm3/releases/

Edit > Engine
. New playing mode added to poly/monon : Unison
. 2 new params added for unison : spread (stereo), detune.
. Glide new mode. Legacy mode was overlap, new Always glide mode.

Mixer > Voices
. Display in red if inconsistency with instrument poly/mono/unison mode
. Fix some page titles

Edit > Operator > Envs
. Fix Multi edit (MENU + encoder) of operator envs

Sequencer
. stop arpegiator when sequencer is stoped

TFT stability
. Improved TFT stability
Slower frequency, hight interup priority, smaller chunks for DMA push)
. Removed TFT backlight in menu (now always 100%).

Dev
. Clean old PCB pinout
. Rename class member variable with "_" suffix (in progress)

[lokki]

. Glide new mode. Legacy mode was overlap, new Always glide mode.

haven't updated yet, but it is not really clear from your statement, is there a new option to change glide or did you just change the default behaviour? i sincerely hope we have both options now glide only on overlap is essential!!

Both options are available : overlap and always.
"Always mode" is really weird

Really enjoying the FM3 Xavier, continuing thanks!

I came across a sort of glitch, maybe, when looking at MIX and then 'Out' - where usually we toggle between 'Jack output' and 'Compressor' but then about every 5 button-presses I get a page that sort of combines the two, and then I also may get an extra screen image 'echo', cut off, at the bottom of the screen.

Also, installed .98b firmware but the screen always shows v0.97b! I wonder why.

And finally, I am having some trouble with loading the mixers I create. It was working for awhile but now whenever I go into my own mixer file and try to load any of the created mixes, the Preen FM3 just freezes. I wonder if the problem could be as follows: I altered some of the 6 presets when playing with the Mixer File but did not save the alterations preset by preset. I only saved the Mixer File itself. Then when the Preen tries to load it is confused. Could that be the problem? I guess I will do some experiments.....

Hi JeffS, Thanks

The glitch you describe is a TFT problem. But it seems you still have 0.97b firmware.

If you see 0.97b in the top right of the MENU page, then you use 0.97b. Not 0.98b.
Easiest way to check is the button Edit>Engine that has 2 states in 0.98 (press a second time on it and you should see the spread/detune option for unison).

And finally, I am having some trouble with loading the mixers I create. It was working for awhile but now whenever I go into my own mixer file and try to load any of the created mixes, the Preen FM3 just freezes.

That cannot be the problem. The Mixer file saves all the 6 presets in its own file.
If that still fails with 0.98b please share the mixer file (it's in /pfm3/  on the sd card ansd its name is "<YOUR BANK NAME>.MIX". I'll then debug what's wrong.

I worked on a new WIKI page this week :
https://github.com/Ixox/preenfm3/wiki/TFT
Will publish a 0.99 firmware later today.

The 98b firmware is definitely on my SD card, at the root [not in the folder]. I select 98b in the boot loader and re-flash it, but it comes up showing 97b, and then when I check under Edit>FM>Engine it has only one page, not the two of 98b.

I don't know what is wrong there.

OK thanks. That's good to know that the Mixer file saves all 6 presets independently. I have now had some success making new ones within the original Mixer file location. But the new one that I created using the "SD" command page -- none of the mixer files within that 'folder' work for me.

I will maybe just wait for .99 firmware and try to install that. Like I said, .98b is not installing for some reason.

And now, the last few times I've used the synth, the TFT has gone completely white and I have to reboot. So am looking forward to the new firmware. The new wiki page on the TFT and its issues was interesting.

There no reason that it does not flash.
If you see the percentage progress while flashing then it's flashed.
I just double checked the version from github and it's fine.

No need to reboot : just press MENU + INST- to reinit the TFT. Didn't that work ?
Would be great if you could try with the improvement in 0.98b but OK to wait for 0.99 later today

I've updated the TFT pages 10 minutes ago with more details on the different TFT PCBs.

[JeffS]

Thanks - that's all helpful.

The issue with 98b appearing to flash, but then the Preen still flashed at 97b, is very strange. I've tried 5 times, always the same result.

Maybe it's because I don't have a bootloader file there at the root? Should I put the file called "p3_boot_1_07.bin" also at the root along with "p3_0_98b.bin"?

I guess it's probably not important though since a new version is coming soon...

[JeffS]

Flashing 99 worked great! I have no idea what was wrong for 98b.

And my Mixer files function perfectly now. Thanks much for the great product and support!
