PreenFM2 / Re: [Solved] [Feature Requeust] Per-Op Keytracking?
« Last post by Xavier on March 22, 2018, 11:59:47 AM »

Hey stelpa,

Isn't FTune what you're looking at ?
Or maybe being able to change with more precision Freq ? so that you can chose something like 0.99 ?

Mod Matrix using midi note number is actually a good way to do that   :)
PreenFM2 / Re: Problem with envelope retrugger

Thanks for the report.
I had a look and saw a problem.
I don't have access to my preenfm at the moment. As you can compile the code, can you try the following :

See here in :
We assign a new voice and return.
without setting this->lastPlayedNote  which is done only line 363.

Can you try to add
Code: [Select]
this->lastPlayedNote  = n;line 295 ?
And recompile ?

After a small debugging session (printing out the env1 state in the display) it appears that the envelope is actually getting retriggered, but that the output is being disconnected from the filter for some reason. I've set a fairly low but not zero sustain level on env1, so when what I thought was the envelope failing to retrigger happens, the filter frequency drops down past the sustain level, which it shouldn't.

(When I downloaded the code I was initially surprised to see that it built right out of the box, the reason being because I've already got almost the same version of the compiler installed for my Midibox projects).
PreenFM2 / Problem with envelope retrugger

I wanted to experiment a bit with the filter in the preenfm2 so I set up a patch with three detuned sawtooth oscillators, filter set to LP, and env1 patched to the filter frequency, with an attack time of 0 and a fairly short decay and release, and sustain set to 0, to get a fast filter sweep.

There is one filter for all voices in the part, so the result is a paraphonic analog synth patch. The env1 envelope should retrigger for each new key played, and indeed most often it does. But sometimes, especially when the same keys are played repeatedly (but not always), the envelope doesn't retrigger. I can't seem to find a pattern as to when it fails to retrigger. It can happen when the same key is pressed in succession, or when different keys are pressed, when I play slow with lots of time between the key presses, or when I play fast.

Is there something else I should be looking at to get this to work or is this a bug?

I'm running firmware 2.08a (the latest at the time of writing).

Part 2 - Operators.
The preenfm2 does offer frequency key tracking per operator through the 3 parameters : "FType", "Freq" and "Ftune".
So i don't understand what you mean.


Hey Xavier - I just revisited this thread when looking through old posts and realized that I misunderstood what you said - what I was asking about was the ability to change key "scaling" - In other words, "stretching" or "compressing" the tuning of a single oscillator, instead of just transposing. Essentially this would make one of the oscillators 'out of tune' with the others - on the blofeld, this allows for some really crazy timbres.

The solution I've found in the mean time to achieve this is to use the mod matrix, mapping the note parameter to an osc's frequency, but I'm not sure which sort of scaling to use. It'd be cool if it were implemented without the mod matrix but that would require a new page... Still lots of fun with the mod matrix though :D
PreenFM2 / Re: custom extended firmware
« Last post by stelpa on March 15, 2018, 02:04:20 AM »
and here is the "standard" firmware with all the additions mentioned in the above post. have fun!

Hey Lokki! I hope I didn't seem rude not responding to such a kind thing, making a custom firmware - I simply had no idea you responded until I found this post by chance, I never received a notification!

Just wanted to let you know that both the new firmwares are working great, thank you so much for doing that! PreenFM has such a lovely userbase :)

Thanks again

I converted all the documentation to PDF format. I like it better that way.
Sorry for the sub par image quality, but the forum wouldn't allow attachements bigger dan 800 KB. :(
I thought I'd share, hope Xavier doesn't mind.
