Didn't work correctly since 2.11

2.20

PCB R6 (24 bits dac) code part of the official firmware

• Fixed compared to 2.20 beta 2
  Sound saturation problem
  screensaver turned off the screen immediatly when enabled

• Only one improvement compared to 2.12
  Selecting preset from midi preselect the bank and programm when want to save them from the menu after.

2.20 beta 2

Loading a patch with midi program change now stores the patch and bank so that you find them immediatly when saving it through the menu.

2.20 beta 1

The status of this firmware is the same as 2.12.

But this version adds the support of the 24 bits dac of the new R6 SMD PCB.
If you have the R6 PCB, previous version of the firmware won't produce any sound.

v2.12

2.12 New features

• Double the power of the Matrix
  Each row now has 2 destinations.
  So you can modulate 24 destinations instead of 12.

• Midi CC7 & CC10 (volume and pan) implementation

• Enveloppe loop (by Toltekradiation / Patrice Vigouroux)
  Modulator operator have now loopable enveloppe.
  Set Release time to 0 and release level to 1.0.

• Glide (by Toltekradiation / Patrice Vigouroux)
  2 more glide values (11 and 12) for slower glide

• Step sequencer new usage (by Toltekradiation / Patrice Vigouroux)
  1 new destination for each step sequencer : the starting point
  Interesting to use with Note1/Note2 sources.

      Step SEQ1     : 0 / 0.5 / Your pattern 1 here (_85F_85F _85F_85F)
  Redirect the Step seq to your destination of choice :
      Matrix row : Seq1 / 3.00 / Mix3 
  Now let's use midi note to select the Step.
      Matrix row    : Not1 / 1.00 / sq1S  (or sq2S)
      Set Note1 to  : Flat / 0 / +ln8

Not really straightforwared but that's it. Each note will trigger a different step and will result in a different sound.

• Matrix new source (by Toltekradiation / Patrice Vigouroux)
  Use rndK to trigger a new random number [-1:1] each time a note is started (key pressed).

• New default firmware is the 192Mhz overclocked version
  Only one version, no need to flash the "o" version.

2.12 bug fixes

• Mix4 & Pan4 destinations now work in the matrix

• Midi DX7 patch selection does not crash anymore when patch number > 31

• Message with animation when USB Key cannot be read (instead of just freezing)

• Filters rework / Merge last modifications from the filter code (by Toltekradiation / Patrice Vigouroux)

2.11

• 2.11a Eurorack only
  2.11a firmware for Eurorack pfm2 attached bellow (p2_cv_2.11a.bin).
  3 new "CV to instrument" modes are avaible :
  seq : instrument 1, 2, 3, 4 but one after each other.
  rand : instrument 1,2, 3, 4 randomly
  cv3 : cv3 input value select instrument depending on its value.

• Internal change
  The Eurorack version is now part of the master branch. Should make easier the maintenance.
  And all the versions (Regular and Eurorack) are in the attached zip.
  p2_2.11 : regular preenfm2
  p2_cv_2.11 : eurorack preenfm (cv = control voltage)
  (each one as a "o" alternative : overclocked)

• Global tuning
  Menu>Set>Tools>Tuning (after midi settings)
  Adjustable between 430.0 and 450.0Hz with a step of 0.2Hz

• more midi MPE support
  Midi MPE needs CC 74 to be available so i moved CC "OP1 Env Attack" to 65.
  And CC74 is now a source of the modulation matrix (last position).
  With Midi All Channel = 1, midi Inst1 = 2, ins2=3, int3=4 and inst4 =5.
  If you load the same preset to all 4 instruments you should have a 4 voices MPE instrument.
  You need a MPE keyboard or Ipad KB-1 app.

• Fix bug when increasing number of voice
  http://ixox.fr/forum/index.php?topic=69580.0
  New voices assigned to the timbre were not correctly initialized, so in some case, that leads to uncontrolled behaviour.

• Filters
  I merged the great work of Toltekradiation (Patrice Vigouroux).
  http://ixox.fr/forum/index.php?topic=69544.0
  All filters are in the source code, so that i can easily merge his future work if any.
  The midi value for each filter is also the same, so preset should be compatible with his firmware.
  I just made the choice to reorder and not to show some of the filter in the preenfm2 UI.
  The new (impressive) list of filter is :
  1 Mix
  2 LP
  3 HP
  4 Bass
  5 BP
  6 Crsh
  7 Oryx
  8 Orx2
  9 Orx3
  10 h3o+
  11 Svh3
  12 Pann
  13 LP2
  14 HP2
  15 Lp3
  16 Hp3
  17 Bp3
  18 Peak
  19 Notc
  20 Bell
  21 LowS
  22 HigS,
  23 LpHp
  24 BpDs
  25 LPws
  26 Tilt
  27 Sat
  28 Sigm
  29 Fold
  30 Wrap
  31 LpSn
  32 HpSn
