preenfm2 and preenfm3 / Re: stuck note! was: aftertouch bug? (or general modulation)

« on: August 20, 2016, 11:23:22 PM »

Thanks, i'll try with my macbook tomorrow.
I don't think it's a DAW or a controller problem, i'm sure it's a preenfm2 problem.
But i think some DAW or midi interface can filter some fast midi data before the preenfm2 got them although some others just pass them through and make the preenfm2 play those wrong note.

I just received some raystar OLED and i cannot reproduce this problem...
Maybe your USB is a bit higher than 5V. I tried several USB power sources, they gave from 4.7v to 5.01v. The Display worked fine with all of them.

I'd like even more than before knowing whether the mod fix the issue...

I played more than ten times your midi file under Linux and in 2 windows DAWs without being able to reproduce.
What firmware do you use ? Overclocked ?
What sequencer/DAW do you use ?
Do you play the midifile directly to the preenfm2 USB ?
If you use the midi jack, what midi interface do you have ?

Last question, does it happen with any preset ?

Thanks

preenfm2 and preenfm3 / Re: Pitchbend response?

Xavier, I know it's not a lot but I would pay 50 EUR for just for getting the Pitchbend properly implemented on PreenFM2. Would that motivate you to spend some effort on this? Thanks for all your great work!

That's very nice of you. But you can keep your money 
I'm trying to find a solution that doesn't kill the performance.

No problem, I don't like knowing a preenfm2 has such an issue.

Read http://ixox.fr/preenfm2/build-it/metal-case/ from bottom to top to disassembly.
- 2 front screws to open the box.
- 4 top screws to separate the PCB from top part of the box.
- 2 last screws on the OLED

As Lokki said, the hardest part is the workk on the OLED itself.
Crefully take off the OLED by puling it from right and left at the same time. Use your 2 hands

Best,

Xavier

You can ask all the questions you want without any problem on this forum

The OLED mod is described here :
http://ixox.fr/forum/index.php?topic=69159.0
The goal is to prevent the OLED from spreading its 16Khz internal noise through the audio path.
Seems like it also has the advantage to fix the Raystar OLED problem.

The shield provided by Van Daal replaces steps 4 & 5.
You still have to do step 1,2,3 which is not very complicated bur requires soldering and a 22 ohm resistors.

Now, I don't think using a 9V power DC adaptor will fix the problem.

in my f4discovery port i'm using Raystrar oled display, at first it had similar strange behavior and the probelm was that the oled was supplyed with 5V power while the driving data lines provides only about 3V high level due to the direct connection to the stm ports. The 3V is way below the datasheet specified input high level which is 0.9VDD (same as in Newhaven oled datasheet). My solution was to lower the 5V power to the oled by a diode, but i'm sure the resistor which was suggested in the oled noise eliminating topic can also be a good solution. Hope this helps.

Thanks a lot Norbim, that's very interesting 
Seems like i was lucky that the NewHeaven OLED worked fine

The 22ohm resistor lower the OLED VDD from 5V to 4.1V if i remember correcly, which makes 3.3v (data high output voltage) closer to 0.9VDD, which explains why the OLED mod fixes the problem.

SoundRider, i can mod  for free your preenfm2 if you want.
PM me if interested.

Yep, i expected the problem to be a timing one

Is your preenfm2 powered by USB ?
Have you tried different power sources ?

Sorry Psyclobin, i've just replied to you PM but i missed this post   

I also read again this thread and saw other people have problem with Cubase
But it seems you have the VST loading inside cubase.

Do you have the midi output of the PreenFM hardware coming inside the VST and the ouput of the VST going to the input of the hardware ?
In fact you should have both, you keyboard and the preenfm2 hardware going to the VST.
The VST Will capture the midi NRPN from the preenfm2 but the midi note from you hardware should be forwarded to the output which goes to the preenfm2 hardware.... Make sense ?

Thanks for the feedback.
Do you think  "DECAL ALL" is enough ?

Hi,

I never saw this problem but heard about it.
It can be a display driver value that does not work anymore with the new OLED.

Could you let me know if it works better with the attached firmware ?

I'll definitely have a look, but not immediately.
My family and I just moved outside Paris and we'll go away a few week.

Any chance to see the oscillators as a source in the modulation matrix?

No. For many reasons.

The Matrix is updated every 32 samples.
No need to read the ADC more often.
