PreenFM1 (the blue one) / Re: Firmware 1.50 Beta1 : Step sequencer inside
« on: December 16, 2011, 06:37:04 PM »

Max, thanks a lot for the feedback.

Is the "Done" behaviour different from how it worked in 1.03 ?
Have you formated the EEPROM user banks  "Upgrade" or "All"...  in Menu->Conf->Format ?

While displaying "Done" the PreenFM expect you to hit "Menu" again... not very intuitive i agree.
Maybe any key should make it go back to the edit mode... or a time out as you suggest...

PreenFM1 (the blue one) / Re: LCD problems
« on: December 14, 2011, 05:10:55 PM »

Hi,

It's better than at the begining ;-)
That really looks like bad connections between the LCD and the maple mini.

Give a look at the PCB schema (the firs in the PCB part, click on it).
http://www.preenfm.net/download/files
And check the connections with a multimeter between the maple mini connections and the top of the LCD on the other side.

PreenFM1 (the blue one) / Firmware 2.00
« on: December 12, 2011, 10:21:12 PM »
Hi PreenFM owners,

Firmwares are here :
http://xhosxe.free.fr/PreenFM/firmware/

How to upgrade is explained here:
https://sites.google.com/site/preenfm/firmwares

2.00 do not means it's bug free... If you find any bugs i'll make a 2.01  ;)
Totally compatible with VST 2.00.B3.


What's new in  2.00
. better (less obvious) cut of existing notes when a new note is triggered.
. adjust encoder timing for better turning acceleration (subtle change).

What's new in  2.00.B3
http://xhosxe.free.fr/PreenFM/firmware/BETA
. [fixed] LFO random now the same as in 1.72 (was higher in 2.00.B2)
. [fixed] Nrpn params fixed to be compatible with 1.72 and works with PreenVST 2.00.B3.
. [fixed] save preset when name length = 12 (no more weird last char).
. [clean] get rid of the old 1.10 upgrade format


What's new in  2.00.B2
. Fixed enveloppe when release was <= 5
. Fixed the LFO env4 problem one some notes.

What's new in  2.00.B1

. Something unexpected 2 weeks ago. Polyphony doubled !! Thanks Olivier (mutable-instruments guy) :-)
  4 voices for 6 operators algos, 6 voices for 3 ops algos, and 8 voices for 3 ops algos.
  The signal/noise ratio is not very good when number of voice > 4. The biggest advantage is  to have  4 voices for 4 & 6 operators algos.

. Enveloppe attacks available in matrix destination. One at a time or all together.
  Can not be changed once a sound is already triggered... but using velocity as source is nice.
  Using a slow LFO to modulate the Attack also give interesting results.

. Peformance row added in engine pages... Allow direct edit of CC1, CC2, CC3, CC4 (matrix control change sources).
  Typical usage : in live can be use to control several internal parameters at the same time.
  Can also be used to control external gear by using the new ECC as destination.
  Remarks : CC1-4 are not saved with the patch.

. Sinus variation tables ("s^2", "1/2s", "spops"), are now centered around 0.
  So they can be used as modulator without changing the carrier pitch... was a bit useless as modulator before.

. CC can now be sent to external gear by selecting one of the ECC in the matrix destination.
  Channel and control change numbers can be modified in the settings.
  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.

 
. Possibility to go directly to one of the patch selection page when booting.
  In the setings, boot : "Default" (as before), "Bank1", "Bank2", "Bank3", "Bank4", "Internal".

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

What's new in  1.72

. [Bug fix] matrix destination clean correctly when changed by midi (fixed saturation when scrolling matrix destination with active source)
. [Bug fix] persistent volume problem when scrolling through presets while playing
. [Bug fix] Sysex bank correctly ignored if not in right menu selection.

What's new in  1.71:

. [Bug fix] now you can load a bank  sending sysex from your PC

What's new in  1.70:

. [VST] Compatibility with the plugin PreenVST v0.4.
. [Bug fix] Midi compatibility with midi sources that uses runningStatus... (fix stuck notes).
. [Matrix] Key added in the matrix source list : allow tu use the midi note number in the matrix.
  As for velocity, the last pressed key is used.
  Also i put (127-note) in the matrix so that the high notes have a smaller value than the lower ones.
. [config] midi "Receive: None" now let modweel passes through, as well as bank select, all note off, all sound off.

What's new in  1.61:
. [fix] There were a NoteOn problem when several notes where played at the same time while other notes where in release state.

What's new in  1.60:
http://xhosxe.free.fr/PreenFM/PreenFM_MidiClock.mp3
. [MidiClock] activity on LCD
. [MidiClock] LFO oscillators frequency : after 15.3Hz you'll find MC/16, MC/8, MC/4, MC/2, MC, MC*2, MC*3, MC*4, MC*8
. [MidiClock] Step sequencer BPM : after 240 you'll find MC/4, MC/2, MC, MC*2, MC*4 (MC = external midi clock).
. [LFO Osc] sinusoid waveform added.
. [Matrix Destination] GATE added : new way of shaping your sound.
. [Midi] Midi latency improved (or should be improved, don't have any serious measures)...
. [Midi] Real midi thru - don't enable it when recording PreenFM midi out...
. [fix] midi indicator did not always blink as it should
. [fix] Step seq 6 : NRPN sent wrong params
. [fix] Step seq gates : in some rare situation they refused to change
. [fix] In Menu mode, values could show up on the LCD

What's new in  1.51:
- Bug fix : MidiClock make the audio engine stuturing

What's new in  1.50:
- 2 Step sequencers
- 4 additional rows in the matrix : 12 rows in total
- Test note added... Hold one second the back button when in edit mode

Thanks and enjoy :-)

PreenFM1 (the blue one) / Re: Built my PreenFM, couple of problems
« on: December 11, 2011, 09:02:48 PM »

2 of my 3 spare side panel are gone.. I think i'll need to order some more soon ;-)

So now the 1.03 is official.
And i'll try to find solutions to prevent this piece from breaking.

Hi deadmonkey,

Thanks for the report.
You're right, there is a problem in the format function in 1.02
I've just uploaded a firwmare 1.03, please let me know if the "format" now works.
http://xhosxe.free.fr/PreenFM/firmware/

Is the broken one of those 2 ?


Let me know and tell me by PM or email your shipping adress, i'll send it to you right now.
If it's an other one, i'll send later... with the order i'll do for batch #2.

By curiousity was it broken in the middle ?
Was the rest of the parcel in good condition ?

Thanks,

Xavier

ah ok. Is there a way to load the firmware then without having to compile all the code from source? I don't have a linux box. :(

Of course, recompiling is only if you want to modify anything...

Here are the instructions to flash a firmware :
http://www.preenfm.net/firmwares

And it do work on new Maple Mini.

Explaining how to build the code is on my todo list and will be on the main site.
It's not straightforward.

If you want to try :

You need a Linux machine and to compile libmaple first.
Take the libmaple 0.0.11 also from gibhub:
https://github.com/leaflabs/libmaple/
Rename limaple directory to "libmaple".

and follow the instructions here :
http://leaflabs.com/docs/index.html

Go ahead untill you can compile it with the ARM cross compiler.

Once this is done, you made the most difficult part.

Take the PreenFM sources from github
https://github.com/ixox/preen

Put the preenFM tree at the same level as the "libmaple" directory.

Go in the PreenFM tree, then "make" then "make install".

Hi Ryan,

Thanks  :D

I have some PCBs left (but not anymore the components to solder on it).

Contact me at the adress here :
http://www.preenfm.net/Contact
Or PM me on this forum (haven't tried the PM yet).

actually the 1.02 firmware update fixed all problems I had so far.
...
so that was a real good one Xavier.

much, much more fun to play.

thank you

Very good news :D

Thanks Max :-)

Towel, i'm glad your problem is fixed.

I'll try to fix annoying problems as quicky as possible.

cheers,

Thanks for the update.

It's possible that the new update 1.0.2 fix the suck notes.
Let me know,

Don't hesitate if you have any more questions.

Xavier

You added a 4 ;-)
This is what glide is supposed to do...
If a note is still pressed, any new note will make the sound glides to the new frequency witout triggering anything.
If you release the old note before pressing a new one, it will retrigger the note whatever the glide value is.

0 = no glide. A new note is a new note from the start.
1 = very fast glide
...
10 = very slow glide to new note.

Do you see something different from this behaviour ?

Hi Marco,

1) Difficult to guess without knowing exactly what you are doing and what is the patch you use when you hear that.
Try setting KSyn=0 in for all LFO.
If the effect disappear  what you hear is the fact that the LFO are global for all notes.
This is how it works for the moment...

2) PreenFM won't play more notes than what says "Voic" in the engine 1st page.
Any new notes stop the older ones.


3) Not sure i get it.
What you hear when modifying the enveloppe is totally different if you modify a enveloppe from a carrier operator or a modulator operator.
Carrier will modify the volume of the sound... like it does in substractive synthesis.
Modulator will modify the spectral of the sound.
This is the same with oscillator.
Look at the PreenFM algorithm schema.... A carrier is any operator at the bottomo of each alg. The modulators are operator upper.

Experiment with simple FM synthesis.
Use  algo1.
Set IM2 and IM3 to 0.
Set IM1 to 4.0
And start modifying enveloppe 1 and 2 and oscillator 1 and 2.
When experimenting with other algo the algo paper you get with your kit is your friend ;-)

80 minutes ?
Your solder skills are far better than mine.

Thanks for this first message in the Forum :-)
You found a bug. I just fixed it.

Thanks a lot,
Let me know if it's better now.
