Firmware 1.06
. Bug fix : When Ksyn = 0.01, LFO started with a huge value that could produce audio click at the beginning of sounds.
Firmware 1.05
. Preset Randomizer in Menu>Load>Rand (Use left buttons to trigger a new Randomization).
. boot sound can be enable/disable in the settings.
. Band Pass filter frequency now reads the FlHz target of the modulation matrix (like LP and BP)
The Last firmwares are available here :

This is the place to report problems or discuss new features...

Firmware 1.04 available :
. New effect : Band Pass. Can saturate, use the gain !
. New effect number 2 : Bit crusher for easier ChipTune sound.
. ENG + INST : list all IMs and their connected operator.
-
awesome, thank you again.
Few things, the frequency modifier in the matrix (FLHz) does not work on the new filter types and would it be possible to use that same modifier to adjust the sample or bit rate of the crush effect.

Bitcrusher is great fun ! :)
same as martindunne :

would be great to modulate those parameters ! i guess i'll map the "filter param 1&2" to my controler for the moment... > hours of tweaking :o :P

Thanks :)
Modifying the simulated "sample rate" from the matrix ? Why not. ?
The simulated "number of bits" is an integer, so you'll hear audio glitches when it changes.
I did not plug the FLHz matrix output to the BP center fequency because when the value changes some heavy floating point operations are done... several divisions.
Having it changing all the time will add a CPU overhead.
But again, why not ? If you hear audio glitches at full polyphony, you'll know what to change.

Cool thing 8) (at least with some waveforms/patches, and tweaking "with caution"...)

I was playing around with my PreenFM 2 today and this Bit crusher is nice. It really gives a nice edge to the sound :)
Question:
I’m curious, what will we see in the future updates? :)
-
Yeah, i like this update too!

What i have on my list :
. Random patch
. BP filter frequency targetable from the matrix
And the biggest feature ever :
. The possibility to disable the sound when the preenfm2 is switched on.
Don't hold you breath, i haven't started...

They're all in 1.05.
Randomizer per synth area... With complexity / Harshness selector.
Don't forget to finalize your sound by hand ;)
Use the left buttons to trigger a new randomization and use "Keep" to well... keep the area unchanged.
I still have to update the documentation.
Don't hesitate to share your feeling,
Xavier

excellent work, randomizer is great fun
-
Yeah, randomizer implementation is smart! Gives really wonderfull results.
Rest features are useful too ;)
Thanks, Xavier!
-
Can't wait to try this! Thanks Xavier!!

Thanks, i'm glad you like it. I like it too :)
The idea of a modular randomizer like this was not from me... someone suggested it in the discussion thread some time ago in this forum. So thank you all :)
-
Modulation for the bandpass. Woohoo! Will have a play on the weekend. Thanks Xavier!
-
Yes, Randomizer is great! Excellent results so far! :)
-
Ok, so I am basically in love with the randomizer - I have created a number of useful patches without "polishing" the randomizer output at all :)
However, one small issue. If I just confirm my degrees of randomization by pressing button nbr 7, the screen says "Done", but no random patch is generated! However, if I press any of the buttons 1-5, and then 7, I get a random patch. This is slightly weird, isn't it?
-
hello there it is awsome. you configure the randomiser with p1- p4 then randomise with any one of the buttons on the left then confirm with button 7 so you can edit further.
-
Ah, ok. So I guess I thought you were setting your randomizer values with p1-p4, and then had to press button 7 to generate the randomized instrument. I just misunderstood the procedure.
-
thhmas, i see what you mean.
Button 7 shouldn't do go to "Done" state before any randomization is done.
Or it should display something like "No randomization. Use left buttons to randomize." instead of "Done" if no randomization was processed.
-

Nicely done, think that was me and was a rip off from the MB6582 way of doing things. Great to see more developments, I've moved on my preen but will hopefully be back at some point in the future to try out the news things!

Hi Xavier,
while having some free time and some fun with the preenfm2, I have a few questions...
1. When playing a polyphonic patch, lifting one note triggers the release of the filter which affects all notes. (I'm guessing there is one filter for all notes.) Would holding on sustain until the last note be better? I'm not sure.
2. The Matrix ranges from -10 to 10. The IMs and frequency go the full range, but the pan, mix and filter only range from +-1. Is there a list of the effective ranges? Is everything else +-1?
3. The Matrix negative values seem to flip the polarity of the sources. Unfortunately, it doesn't seem to work with the filter. Is this possible?
4. I've noticed there are a couple of duplicate algorithms. 7 and 12, 8 and 15. Is there a reason behind this?
I'll share some patches soon. Likely in installments.
Thanks!,
Martin.

Hi Martin,
1. Yes.. I think that's what we call paraphonique.
You feed the filter frequency with one of the free enveloppe ?
I agree it would be better to wait for the last note to finish... Not sure it's easily doable. I'll have look.
2. I think the general rule is that cannot go higher or lower than what is authorized directly in the UI.
3. What would you expect exactly with the filter. I'm not sure i understand.
4. Algo 1 to 9 comes from the preenfm. And greater than 10 from the DX7 for patch compatibility. So there maybe some duplicate..
Looking forward for you patches :)
Xavier

1. Yes. I'm applying a free envelope to the filter. So, all notes share the mod matrix including 'note number'? I guess that would be paraphonique. :)
3. Maybe this is more of an envelope issue? I haven't thoroughly tested it... Ideally, if you assign an envelope with positive modulation to the filter, the envelope starts at the cut off frequency and rises up in frequency in the attack etc. If you assign negative modulation, the envelope starts at the cut off frequency and drops down in the attack etc.
4. Ahhh... that makes sense.
thanks,
Martin.
-
3. Ah OK.. Cannot try right now but this should work. You should be able to move down the cutoff frequency with the envloppe when using a negative matrix multiplier.

Any updates to look forward to? ;)
