Firmware 2.0 wish list....
« on: August 02, 2012, 12:05:25 AM »
Hi everyone,

I have some time to work on new features during the following week.
What do you think is missing in PreenFM ?
What would you like to see ?

Here is what is already coded :

. Something unexpected 2 weeks ago. Which is the reason why i call it 2.0 !
Polyphony is doubled !! Thanks Olivier (mutable-instruments guy) for the advices  :-)
  >> 4 voices for 6 operators algos .
  >> 6 voices for 4 ops algos.
  >> 8 voices for 3 ops algos.
  But  6 voices and 8 voices requires headroom for the summing so the signal/noise ratio is not very good per voice.

. enveveloppe attacks available in matrix destinations. (Nice when controlled by velocity).

. Peformance row under "engine" pages... Allow direct access to CC1, CC2, CC3, CC4 (control change matrix sources). For performance only, not saved with the patch.

. better new note algo... sounds much better with long release patches. No more obvious release cut.


Look nice already, no ?  ;)

This is what i've been dreaming of...
Sounds like my Yamaha TX81Z is finally going to the bay  :)

Now i just need a new more sturdy case, it's got several cracks already  :o

Xavier, I'm the guy who started the thread on the Mutable Instruments forum.  I was looking for some feedback on the PreenFM and it seems everyone over there is quite impressed with it.

Olivier is most certainly a special guy, very impressive and it is great that he was able to help you out.  I'm really looking forward to ordering a PreenFM when they are back in stock.

@loderbast : thanks  :D

@rasmus : keep you TX81z....
I have one and the sound is very different from the PreenFM.
The PreenFM is much much more flexible and the step sequencer, the gate, the midi clock sync (...) allow you to get some sounds the TX81z cannot dream of....
But the TX81z sound is more crystal clear when that's what you're after.
[EDITED] i've just scroll through the TX81z preset and it's not at all crystal clear... use FM8 if you want crystal clear FM sound  ;)

@randy : Hey.. thanks.... that was a usefull thread indead  ;)
Olivier gave me great optimization advices.... Seems like i've been programming in Java in my daily job for a much too long time.


Added in WIP firmware 2.0.B1 :

. Option to go directly to the patch selection in one of the bank when switching on the Preen.

Oh, brillliant!  I can't wait.
Another request... The ability to set the mod matrix destinations to CC1-4 to allow control of external filters / gear.

One thing that would be cool, although maybe it's not possible, would be for the IM settings changes to happen to a sound that has already been triggered. Right now, when you change the Index, it doesn't take effect until a new note is triggered. At least on my unit haha.

Great Stuff! I look forward to some new firmware and trying to remember how to flash the maple haha.

Thanks for the suggestions  :D

@funkyfli : Interesting... I'll try to do that...
Wouldn't it be better to have 4 other Control Changes instead of using the same : ECC1-4 (E=external) ?
And maybe the ECC1-4 control number could be defined in the settings (as well as the channel).
Using the Midi clock sync in the PreenFM LFO and sending these CC, that would allow to send synced LFO to any external gear that do not support Midi clock sync... I like that !!

@Ryan :  ?  :o
That the base of the (Preen)FM sound synthesis... being able to modulate the IMs inside the sound...
Many of the presets send LFO and step sequencers in the IMs during the sound... also changing the IMs manually that should work.
Could you try again and confirm ?  Or maybe i didn't get what you meant. ;)

@funkyfli, if you want to give a try at the ECC here are some explainations :

"Correct values in the modulation matrix to have 0-127 range in the ECC:
   . Source : CC1-4 : mul = 16 : Dest ECC1-4
   . source : LFO1-3 : mul = 8 : Dest ECC1-4
     LFO1-3 must have bias = 127 because they must be positive only."

Hope the helps,

xavier

Hi Xavier, I just started testing the update and I am loving the performance page / ECCs!  ;D 
One issue I have noticed right away is a sustained frequency on some of my patches when I release a note.  eg. Patch 10 - CalQLate in the bank.  The frequency does not fade away.  I haven't been able to determine a cause in patch settings.  Can you reproduce this?

And, thanks for fixing the s^2 etc. oscillators.  I meant to ask about them  :)

Thanks.

Ok.  I found a bug with the LFO Env 4.  :)  In mono, if you play a note, then a higher note and release the low note the envelope continues correctly.  But, if you play a note, then a lower note, then release the high note the envelope ends abruptly.

Thanks.

Great... thanks for the reports.  :D

I can reproduce the problem with CalQLate... I've just fixed it. 2.00.B1 is buggy is the env has a realease <= 5.
Your bank is not only great, it allows to detect bugs ! :-)

The second one was a bit harder.
As far as i understood in depends on the first note played.
Anyway i think it's also fixed in 2.00.B2
