preenfm2 and preenfm3 / Re: Will this screen model fit the new metal case?

« on: August 13, 2014, 10:49:03 AM »

No, the metal case requires the OLED screen (newhaven which is thiner).
The previous LCD one does not fit.

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.

preenfm2 and preenfm3 / Last firmware 1.06

« on: August 10, 2014, 09:11:57 PM »

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...

preenfm2 and preenfm3 / Re: preenfm2 Editor: 0.4 (osx/win win32/x64 standalone/VST)

« on: August 10, 2014, 09:05:07 PM »

I have some ideas after testing, which I want to share.

•         1. Randomizer knob, where can click and the unit will set “random adjustment” on the different parameter
•         2. The unit is 4 part multitimbral, how about 4 fans with each 4 part so you can fast switch between them?
•         3. I know there is space for lots of presets and combos, what about a menu in this editor where you can choose between the slots/banks
•         4. Load DX-7 patches directly into the editor. There are lots of free Yamaha DX-7 patches for download out there and they are as “.Syx” format. Additional loading patches for Yamaha tx-81z and Yamaha FB01 if they could be compatible for this unit.

Seems like i forgot to reply.
Thanks for sharing ideas.

1. Yeah, I'd like to find time to add a randomizer in the preenfm2 itself, not in the editor. It has been discussed, and people shared ideas how to implement that.Than cannot be a simple random value for each parameter. Maybe next big feature...
2 . It's already possible to switch (easily ?) between the instruemnts. Change midi channel then press "Pull". Making all instruments available at the same time would require a big rework.
Yes dealing
3. Agree... Having better slots/banks editing possibilty would be great.
4. Maybe one day....

No that only works with integer.
And the buffer is still in floating in the effect processing.

But i think i have something that works...
Will share soon.

« on: August 10, 2014, 12:58:46 PM »

Congrats, it's always nice to see a new preenfm2. 
Specially when the builder spent much time on it 

Yes, the MC33202 through hole is not built anymore.

But there are several other  DIP8 alternatives :
The one in the Kit :

Another one :
http://www.mouser.fr/ProductDetail/Texas-Instruments/OPA2340PA/?qs=sGAEpiMZZMtCHixnSjNA6Mrdwin7F8A2ufI6Oo3Mpig%3d
Or even the cheap MCP6002 (used in the meeblip) :

A bit crusher ?
Do you have such a effect working ?
Cannot see anything like this in you fork:
https://github.com/matrix12x/preenFM2

By the way this branch is based on an old firmware/bootloader (0.9i / 1.02).

preenfm2 and preenfm3 / Re: Combo change ?

« on: July 28, 2014, 09:14:28 PM »

  Sorry for the confustion what i wrote was totally wrong.
The bank is done with CC and the loading the preset is a program change. No NRPN here.

You select the bank with CC#0 (bank select) and CC#32 (bank select LSB) as describe here : http://ixox.fr/preenfm2/manual/midi/
See the midi messages : http://www.midi.org/techspecs/midimessages.php

Then you can use "program change" to change the preset inside the bank you selected.
See program change in the top of the table in the previous link...

preenfm2 and preenfm3 / Re: Combo change ?

« on: July 27, 2014, 09:20:54 AM »

Hi,

How to change a combo by CC or NRPN ? I've tried to send MSB#1 + LSB#32, then the number of my combo, but it doesn't work. Do i miss something ?

That should work.
You followed the NRPN here : http://ixox.fr/preenfm2/manual/midi/ ?
What did you send exactly ?

EDITED : Oops... What i wrote was totally wrong !!

Are the combo unique when we save them ? If i change a program that was in multiple combos, does it change all the combos ? Or each combo are independant.

The Combos are totally independant from each others and from the presets.
Modifying a program in one combo does not change any other programs.

preenfm2 and preenfm3 / Re: Clarifing modulation indexes?

« on: July 27, 2014, 09:15:30 AM »

Hi,

Thanks for the feedback. 
Yes there is a hierarchy that you'll find in (almost) all the algos. Lower IM level from left to right then, than level above from left to right.
Also at any moment you can press "Engine + Menu" to see the schema of the current algo.
But you seem to have already noticed that.

And i agree, a list of all "IM1: Op3->Op2" for all IM is a very good idea.
I'll add that when i have time. (I'm currently in vacation  )

« on: July 18, 2014, 09:58:28 AM »

Xavier,
Thanks for all the awesome work!!!!

I am on OSX 10.9.4 and it works great. Although, when I hit "Pull" I get a high pitched whine for a half second or so if I was playing notes. If I understand, there is no OSX VST yet, correct?

Thanks for the feedback and nice words 

When you hit pull, the preenfm2 audio engine stop while sending all its parameters to the editor.
I don't think it's worth the work to avoid it as you're not supposed to press pull while doing important live session

Actually there is an OSX VST version in the DMG: "pfm2Edito.vst".
I don't know the usual VST instalation procedure under osx but here you'll have to copy this file in your "Library/Audio/Plug-Ins/VST" folder.
If Library is not visible, right click "show view option" and check "Show Library Folder".

still not working for me on win xp 32bit, still saying that its not a valid windows application. it does work on windows 7 tho.

Thanks for the feedback. I exepcted it to work.
Sorry but I think i won't support XP as it's not straightforward with latest Visual studio, and i don't have an XP machine to test on.
