    Firmware v0.26
    ---------------------------
    merged with rudeogs changes:
    - Pattern/Kit save will use a proper cursor when editing names
    - Midi Off - Will now send midi note off messages before the next midi note on message and also
    when the sequencer is stopped. This allows better interaction with external synths.
    - Note names - instead of showing -63 to 64 it will show real note names like C, C# D, etc. This
    is useful when using the LXR as a sequencer
    - Midi Note. Each voice has an assigned midi note. If this is set to C0 then it will play the
    note assigned to the sequencer step, otherwise it will play this note. This replaces the
    standard behavior and allows one to set the note that is played for the drum sound (old behavior
    was to have the note fixed when in trigger mode).
    - Midi mode has been removed (the above feature allows more flexibility)
    - LFO target fixes - Setting LFO targets is now much easier. The list of targets is
    straightforward and more descriptive. There are no missing entries or dupes.
    - Velocity target - Same type of fix as LFO target
    - Automation target - Same type of fix as LFO target. Also menu is more descriptive.
    - Separate open and closed hi-hat EG decay onto separate drum buttons to make it clearer which
    one is being edited.
    - Fix firmware image builder to accept command line parameters, and create new batch file
    - screensaver bug on load/save page fixed
    - encoder works for changing mod destinations in detaled view

    Firmware v0.25
    ---------------------------
    - added user sample (.wav) import from SD card
  • Okay, the trigger IO update is ready and available on the server
    https://github.com/SonicPotions/LXR/raw/master/firmware%20image/FIRMWARE.BIN
    or
    http://www.sonic-potions.com/public/FIRMWARE.BIN

    Firmware v0.28
    ---------------------------
    - merged with rudeogs fork (not his latest version. he's too fast ;) )

    - refactoring of internal track length handling -> fixed out of loop/tracklength problem
    - trigger IO clock scalers added
    - fixed trigger IO start/reset input pin
    - fixed sine OSC offset bug (start is now on zero crossing)


    Rudeogs changes:
    • Midi filtering. You can filter messages from being transmitted or
      received. Tx is independent of Rx. There are four categories of messages
      that can be individually configured: Program Change (P), Control Change
      (C), Realtime start/stop/clock (R), and Note on/off (N). These are set
      in the global menu under txf and rxf (transmit and receive
      respectively). Combinations of letters are shown. If a letter is shown,
      the midi message in that category will be transmitted or received. If
      set to off, nothing is sent/received, and if set to all everything is
      sent/received. This has nothing to do with midi routing which works the
      same way regardless of filter.
    • Midi routing (midi soft thru). You can route midi messages from
      input to output. This is set in the global menu under "mrt". There are 6
      possible values: off - no routing, U2M - usb midi is routed to midi out
      port; M2M - midi received on midi in port is routed to midi out port;
      A2M - both usb and midi are routed to midi out port; M2U - midi input
      port is routed to usb output port; M2A - midi received on midi port is
      routed to both midi output and USB output.
    • Midi note off fixes. Will send midi off when changing pattern, channel or muting voice
    • MTC sync. Will now recognize MIDI MTC quarter frames and start when it receives a 0:0:0 location, and stop when MTC stops
    • Program change. Will respond to program change and will change
      between the 8 patterns when received via MIDI/USB port. For programs
      > 7 will use remainder when divided by 8. Program change will only
      respond to PC messages on the global midi channel.
    • Program change. Will send program change 1 to 8 on MIDI when
      manually changing drum patterns. The channel that it sends it on is the
      configured global channel
    • Control change. Should only respond to CC messages on the global midi channel.
    • Pattern/Kit save will use a proper cursor when editing names
    • Midi Off - Will now send midi note off messages before the next midi note on message and also when
      the sequencer is stopped. This allows better interaction with external synths.
    • Note names - instead of showing -63 to 64 it will show real note
      names like C, C# D, etc. This is useful when using the LXR as a
      sequencer
    • Midi Note. Each voice has an assigned midi note. If this is set to
      C0 then it will play the note assigned to the sequencer step, otherwise
      it will play this note. This replaces the standard behavior and allows
      one to set the note that is played for the drum sound (old behavior was
      to have the note fixed when in trigger mode).
    • Midi mode has been removed (the above feature allows more flexibility)
    • LFO target fixes - Setting LFO targets is now much easier. The list
      of targets is straightforward and more descriptive. There are no missing
      entries or dupes.
    • Velocity target - Same type of fix as LFO target
    • Automation target - Same type of fix as LFO target. Also menu is more descriptive.
    • Separate open and closed hi-hat EG decay onto separate drum buttons to make it clearer which one is being edited.
    • Fixed some minor bugs that were annoying me.
    • Add Eclipse CDT support for AVR. This allows all development of front and mainboard to be done in one
      Eclipse workspace, and gets rid of the need for installing AVR studio
    • Remove generated files. These makefiles are generated by eclipse and contain local paths etc. No need
      for them in the source tree.
    • Fix firmware image builder to accept command line parameters, and create new batch file



  • found the bug. another new version is up wich fixes the double trigger problem.
    https://github.com/SonicPotions/LXR/raw/master/firmware%20image/FIRMWARE.BIN
    or
    http://www.sonic-potions.com/public/FIRMWARE.BIN

    Firmware v0.29
    ---------------------------
    - fixed the double trigger bug on the clock outs
  • Firmware v0.30
    ---------------------------
    - fixed panning mod problem for snare, cymbal and hihat voice
  • Firmware v0.31
    ---------------------------
    - Added 'gate mode' for trigger IO

    A new parameter 'Mod' on the trigger IO config page is added.
    This sets the mode.

    At the moment it still says on/off, will change this to trg/gte.
    If set to on, the trigger pulse duration will be determined by the amplitude envelope.
    So you can set different pulse widths for the trigger IO pulses by varying the attack or decay settins of the amp EG.
  • Firmware v0.32
    ---------------------------
    - fixed LFO sync in MIDI slave mode
  • Time for another update. It can be found on the normal adress:
    http://www.sonic-potions.com/public/FIRMWARE.BIN
    or
    https://github.com/SonicPotions/LXR/raw/master/firmware image/FIRMWARE.BIN

    Firmware v0.33
    ---------------------------
    - usb MIDI out fixed
    - USB interrupt bug fixed (PLD)
    - OSX USB MIDI fixed (PLD)
    - Trigger IO will now send tigger signals on incoming MIDI notes
    - MIDI Note Off is send when amplitude envelope reaches zero (global settings gate mode parameter 'mod' has to be set to on)
    - change in pattern data structure. Pattern lenghts of old patterns is ignored on load. you have to re-set them and re-save the pattern to store it in the new format (once)
    - LFO target voice fix (thanks rudeog)
    - fixed include path names in source (all '\' are now '/', propper upper and lower cases used)
    - fixed modulation target osc 3 waveform in HH voice
    - fixed mod target for LFO amounts and waveforms
    - added makefiles from Patrick Dowling

    Once again the firmware was merged in the latest changes from rudeogs repository:

      - Merge TB323's repository which includes a "rot" parameter in the pattern generator allowing you to apply a rotation while generating a pattern.
      - Remove untargetable modulation destinations from menus (LFO mod target, and LFO voice can't themselves be modulated as it doesn't make sense to do so)
      - Pattern Rotation - When in performance mode, if you hold shift button and select one of the sequence step buttons you can rotate the pattern for the active voice by a number of steps relative to the other voices.
      - Save/Load performance - this new save option lets you save the current drum patch along with the pattern set and the BPM into one file allowing multiple slots.
      - Save/Load all - this new save option lets you save all the data in the LXR (kit, pattern, settings) into one file allowing multiple slots.
      - Better handling of startup not finding the default drum kit. Will display an error and continue with a patch that needs editing before it will work.
      - Realtime erase - This is useful, I've found, when recording sequences on a keyboard that are multiple bars (measures) in length. Hold down shift and copy(clear) button. While these are held, the notes on the active voice are erased. You must be in record mode, and the sequencer must be playing. So you could erase a few bad notes as you listen to your sequence, or erase multiple bars as they switch without having to mess around with selecting patterns.
      - Recording quantization enhancement - When recording a sequence that spans multiple bars, if you are quantizing, and you hit a note right before the next bar starts (such that the note should quantize to the next bar's first step) it will now do so.
      - Global menu can now hold more than 8 items and will scroll to page 3 (and beyond) when toggling pages or moving encoder right
      - Pattern change reset mode. This is a new global setting that, when turned on, will cause song counter to start from 0 whenever a pattern changes. This prevents the behavior of not playing the displayed number of repetitions for a pattern (when in certain song positions. see the LXR manual).
      - Global midi channel setting. Affects recording notes from external gear, program change, and control change messages.
      - Active voice control and recording. When a voice is active and notes are received on the global midi channel, they will be sent to the active voice, possibly recorded on the active voice, and echoed on the active voice's configured channel (all of this regardless of what channel the active voice is set to)
  • Firmware v0.34
    ---------------------------

    - added new 2 pole lowpass filter "LP2"
    - fixed USB VID/PID
    - MIDI Bank change now select drumkits (program change selects pattern as before)
    - fixed missing finetune for voice 4 to 6
    - merged in PLDs CCM branch. Moved some stuff to faster core coupled memory.
