preenfm2 and preenfm3 / Troubleshooting sudden display bug
« on: February 22, 2015, 08:15:46 PM »
Hello there; i was hoping someone could help me troubleshoot my suddenly appeared preenfm 2 problem. It was running fine until recently when after powering up the weirdest gibberish was showing on my display ... the leds flash when the preens powered on and it seems like navigation still works even though the display is unreadable - also, on powering up i can hear the audio activating so probably its a matter of display only. My first thought was maybe switching the firmware (current version has also worked before) might troubleshoot this but weirdly when trying to enter the bootmode pressing 1, the display stays all dark (leds keep lit though).
Has somebody experienced the same, or - maybe an idea on what this could be caused by? I'd appreciate any! hint

PreenFM1 (the blue one) / Re: One more PFM (midi trouble though)
« on: June 03, 2012, 06:08:40 PM »So - i tried the preen on the midi ports of an edirol ua-25 and this works all fine. So after all the buggy midi is the mk3's fault; shame on motu! I guess ill try a dedicated usb to midi box, this should work after all.
Here's a small update on this issue - motu released an update on the universal audio installer including the firewire and usb midi drivers (Version: 1.6.52865). It seems like they have fixed the midi/snowleopard issue - Preen works now fine directly connected to the mk3

Alright - i'll have a comparison with another soundcard tomorrow - by the time it seems most likely that this is an issue of the motu mk3 ;(

Hello Xavier and thx for yr quick response ...
the behaviour as you put it is exactly what i am trying to describe. Note B locks note A and a second hit on note A ends it.
I just checked again with version 1.61, 1.60 and 1.51, the issue remains on all 3 versions.
I checked with another controller, the issue occurs with both the akai lpk8 and the lpk25 (have to check with direct midi as soon as i find a non usb controller)
The behaviour is also the same on both ableton live 8 and cubase sx 4le. It does not make a difference, if i use a controller playing the keys or if i play back notations drawn inside the sequencer, still the same issue.
Setting release values to zero on the preen also makes no difference.
Hope those infos make a difference. Midi file is on the way

So it turned out the 6n137 was broken. Got another one for less than 1€ and this one fits perfectly
Since midi is working again, i did some testing and i was surprised that i am having note off/polyphony issues very much like those described in the bug that led to fix 1.61 (i am running this version, so i guess it cant be the exact same bug). Every second note played on top of a running note wont play, but causes the first note to get stuck. A third note will play simultaneously with the note that is stuck (first one). Whenever ill hit the key of the stuck note again, it stops playing.
The preenfm is connected to a motu ultralite mk3 & akai lpk8, the motu might be causing this issue too so ill do some comparison with other midi devices.

Okay, so it seems i killed the 6N137 
during troubleshooting (didnt get any more midi feedback since the .61 Update).
I think this one would fit as a replacement? http://de.farnell.com/jsp/search/productdetail.jsp?sku=1021197&CMP=KNC-GDE-FDE-GEN-SKU-MARGIN&s_kwcid=TC|13114|6n137||S|p|8788799707 (I'm not quite sure if theres variations on this one out there).

. Check twice you inserted the 6N137 in the right direction

Hi there ...
I guess this might be a good place to ask - I am pretty new to the topic of fm-synthesis; is there any particular literature, tutorials etc / resources on FM that you can particularly recommend? Any tipps are appreciated

Yo xavier - thanks for the quick reply, you named it - problem was the optocopler ic which i had put into the wrong direction 
... now it runs perfectly ... and i was quite surprised to have a visual midi feedback on the display - nice one - i did not expect that! All in all i have to thank you again - for support and designing this awesome box - decent usability and quite the sound i was looking for - good times ahead
Felix
... ps - is it possible to order spare parts of the plastic box side panels? seems one of them broke during the transport ;(

I finally made it to build my PFM Kit yay ...
Plugged it in and it even plays the welcome sound - but i wonder why it wont play anything via midi in ... is there some tweak i might have missed in the configurations? probably not - xavier - do you have any ideas, why midi might not work?
Best & thx for all the efforts Felix
