PreenFM2 / Thank you Xavier!
« Last post by mackemint on June 29, 2018, 01:44:37 PM »
I just finished my build I'd laying around for quite a while.
Super-simple and fun build, great documentation and the PreenFM2 itself, goodness!
It's really a great instrument, this was my first serious introduction to FM and I was thinking that the programming would be a bit tedious. To my surprise, it's pretty straightforward even using only the panel.
Really love it and I'm super happy I got the opportunity to get this thing in my possession =D
Super great engineering work, so impressed!

My only gripe is that the MIDI out jack doesn't thru the MIDI from USB, is this something that would be possible to do in a firmware mod?

Thanks again
Cheers

PreenFM2 / Re: Editor strange behaviour. Corrupt edit when pushing to FM2
« Last post by element-s on June 29, 2018, 10:05:50 AM »
Hi Xavier, it is the standalone. Tried on Mac Os X and it happens in Mavericks, Yosemite, El Capitan and Sierra. MacPro and Macbook air.

USB conection only and no

Steps.

While editing any patch (loaded from DX7 or internal preset) sysex try to push the patch to the Preen and patch becomes corrupted. Often by re-pushing solves it or make it worse. It is random.  Other times it completely corrupts the patch and is irrecoverable rendering work unusable. I sounds like it alters the FM levels, envelopes possibly and modulation index. FM frequency ratios seem to be maintained ok.

I have noticed that if you are playing a midi keyboard or if there is a midi sequence coming in to the FM2 (to test the patch edit), the corruption can be worse. Sometimes by stopping the midi note and waiting for it to die away and then pushing again can resolve it. Maybe some weird MIDI loop going on?

thank you very much.

Hi,

Do you use the standalone editor ? or plugin ?
What platform ?
Do you have reproducible steps ? Or a preset that fails..

To reset the preenfm2 audio when notes are stuck press : INST+MENU

Thanks,
Xavier

Thanks for the reply. AT least I now know its not just me. Thanks for the restart tip. It is a tad frustrating though. Great editor!

I do not recall this bug specifically but it´s been a while since i used my PFM2 with the editor. I recall it being a little bit buggy, and sometimes i had trouble either getting the data from the editor to the device or the other way around. Usually i restart it all and this makes it go away long enough for me to be satisfied.
But still yeah it´s a bug alright, even if it´s a small one and easily fixed by myself.

PreenFM2 / Re: preenfm2 editor 2.08.4 (November 25th 2017)

about the bug reported by mbng,
as workaround, i use a puredata patch that send All note off (CC#123) or Hold Pedal = 0 (CC#64)
one or the other, depending what is needed.

I hope it help.

note : using OSX 10.9

PreenFM2 / Editor strange behaviour. Corrupt edit when pushing to FM2
« Last post by element-s on June 27, 2018, 08:31:35 PM »
Hi all,

have just been doing some editing on the 2.08.4 editor.

When pushing an edit to the Preen it often gets corrupt. I have noticed that it is if there is still a midi note in course. But even after the midi note event has died away then the editor behaves erratically when pushing to the FM2. I just lost an edit I had been working on. Bothe the editors version and the Preens current edit state have become corrupt. No sign of it visually but just in terms of the sound

Maybe for a future update, it would be great to be able to load and save directly into the editor from the DX sysex file. POssibly a big pain to implement, but trying to think of options in order to not loose work like this.

Any ideas? Many thanks

PreenFM2 / Re: custom extended firmware

Hi all, this is pretty awesome! I just ordered my first PreenFM2 and am just waiting for it to get here. 
I was guessing it was opensource, but I just bought it without knowing, and finding out about all of this is just great!
I will need some time to try the standard, then want to try the 8 timbre one, but I may want to help expand it out too if I can.
I code in many languages and the src looks approachable. This is exciting!
I've got some ideas, but I want to try the basics first and then see what I think is useful.
Thanks for all your work!

PreenFM2 / Re: Problem starting PreenFM2
« Last post by Xavier on June 18, 2018, 11:10:49 AM »
Now I don't know what I'm talking about obviously, but: Would it make sense to have the screen say "Reading USB..." instead of just blocks at that point, so that it is obvious that the problem is USB related?

When i wrote this part of code i didn't expect the USB reading to fail with some USB stick.
But that's a good point ;)
