Fast firmware update

To update Hermod:
● remove Hermod from your eurorack case, push and release the micro SD card
● put the micro SD inside the SD adapter and insert it in your computer
● drag the "hermod.bin" file into the micro SD card (do not change the file name)
● insert the SD card in Hermod
● power on Hermod while holding the encoder and wait a few seconds
● the version is displayed on the startup screen

Download hermodOS 1.20

● we encourage users to regularly backup projects besides the SD card
● in case of any issues while updating the firmware or saving projects, please format your SD card with your computer ("FAT32" with Windows, "MS-DOS FAT" with Mac)

For now on, every bug reports & suggestions must be sent here:

hermodOS V1.20
december 6, 2018

New features

● STEP MODE: now you can reset the selected note to C4 (click the encoder, select CLEAR SELECTED NOTE).
● STEP MODE: if no modulation is recorded on a MOD track, the screen displays a dotted line.
● STEP MODE: if your are not in a modulation track and you hold STEP+rotate the encoder, you will change the octave of the selected note.
● MIDI FX: new parameter INPUT MOD. Allows you to select the input CC number, in order to control the modulation track (in previous versions, CC1 was the only possible CC number). Note that you will still be able to use CC1 (modwheel) even if this CC is not selected.
● MIDI FX: new parameter ALLOCATOR. Allows you to select how the voice-stealing works, when the track layout is polyphonic. You can set CYCLIC (when a new the note is received, the next free voice is allocated), POLY (same as in previous versions, works closely as cyclic but if a new note was already allocated on a voice, this voice will keep this new note), FIRST (the first note will always play on the first voice, the second note will always play on the second voice, ... ), RANDOM (voices are randomly allocated).
● TRACK MODE: a small "x" is displayed on the screen, if the track includes events (notes, modulation, gate, pitchbend or aftertouch).
● SETTINGS: new parameter CV IN > QUANTIZE NOTE = ON (GATE). Get and convert inputed CV/GATE note only at the moment when the gate goes low to high.
● SETTINGS: new parameter CV IN > RANGE = -2.5V > 2.5V, in order to scale a -2.5V ... 2.5V input signal to Hermod's standard -5V ... +5V
● SETTINGS: new parameters CLOCK > CV CLOCK OUT = G1+RESET, G2+RESET, ... G8+RESET. When selected, Hermod will output a RESET signal on the CV output (together with the clock on the GATE output), helping your modules to keep the sync when PLAY is pressed.
● PROJECT: for more safety, now you have to press X to load a project or delete a project (in the project list).
● LFO FX: DESTINATION = MOD is now selected by default when you work on a MODULATION track.
● TRACK LAYOUT = 1 VOICE: MODULATION is now selected by default.
● Lowest BPM is now 1 instead of 40

Bug fixes

● Encoder precision improved.
● ABDC inputs precision and calibration improved.
● Monitoring CV/GATE inputs AB or CD (to the CV/GATE outputs) is now only possible when the track is either recording, empty, muted, or if the sequencer is stopped.
● When you enter a menu, the selection cursor is now always on the left.
● TAP TEMPO: the limit is now fixed to 250
● Freeze with DELETE PROJECT empty selection fixed.
● Freeze with PASTE TRACK fixed.
● STEP MODE: the C10 note is now accessible with the piano roll
● STEP MODE = MOD: changing the GATE length was adding an event MODULATION.
● STEP MODE: advanced mode is now working.
● Hermod freeze at startup (when receiving incoming midi clock) solved
● STUCK GATE fixed (when we change the current track, and that track was assigned to CV/GATE inputs).
● SETTINGS > CV IN > RANGE now works (in previous versions, 0V>5V worked as the -5V>5V parameter).
● STEP mode: fixed a bug that was making difficult to enter a step when this one was already including pitch or aftertouch.
● SCALE FX: changing TRANSPOSE parameter was working when if the effect was muted.
● SCALE FX: CHROMATIC, OCTAVE, MAJ THIRD, FOURTH parameters now works as they should.
● DELAY FX: DRY/WET = 0% was playing the delayed notes, instead of playing only the original note.
● DELAY FX: problem with unsynced delayed notes fixed.
● HARMONIZER FX: the HARMO 4 parameter now works.
● MIDI OUTPUT FX: now it does not send the pitchbend, aftertouch or modulation CC if no changes have been detected.
● SWING FX: sometimes, the very first notes of the track were missing.
● LFO FX: when we change the BPM, the LFO effect keeps its sync.
● PROJECT: LOAD is faster. SAVE is more robust. Latency when we enter the LOAD PROJECT list is drastically reduced.

hermodOS V1.10
september 22, 2018

New features

● AUTOLOAD: now Hermod loads at startup the last saved or loaded projet (hold STEP at startup to direclty load a new project).
● New parameter GATE RETRIG is added in the effect MIDI. If enable, the track will re-trigger the gate output each time a new note is overlapping an other note, in order to break the glide/legato. In other words, when a new note is sent to the CV output, the GATE output will always be triggered.
● Hard Rec: in STEP mode, hold Y and press REC to enable a "hard rec" recording (= no overdub). Previously recorded notes will be overwritten.
● CV inputs: added parameters in SETTINGS > CLOCK > CV TRANSPORT = CV PLAY A/B/C/D. A continuous high level on a CV input will play Hermod, a low level will stop Hermod and reset the player position ("DIN sync" start/stop standard).
● CV inputs: added parameters in SETTINGS > CLOCK > CV TRANSPORT = CV REC A/B/C/D. A continuous high level on a CV input will enable the recording, a low level will disable the recording.
● Project Menu: NEW PROJECT is added at the end of the list.
● LFO: now, the LFO EFFECT range can be set up to 200% in order to get the maximum output voltage of +/-5V.

Bug fixes

● Fixed a bug making gate output always high (because of a stuck notes), when using some USB controllers (eg the Keystep).
● CV IN sync: fixed a bug making Hermod to start with a latency when SETTINGS > CLOCK > CLOCK SOURCE = CV A/B/C/D.
● LFO FX: unsync problem with some rates (eg 1/8) now fixed.
● DELAY FX: DRY/WET=100% now never play the original note.
● Loop Full: fixed a bug making Hermod to play an other sequence before the end of the FULL loop.
● Fixed a bug making the user interface behaving differently (or making the screen not updating new values) when SETTINGS > CLOCK > SOURCE different from INTERNAL.
● modMatrix: CC11 was missing
● modMatrix: now you can validate a parameter (eg midi:root note) by simply leaving the modmatrix, without clicking the encoder.
● Freeze: Fixed a bug making Hermod to crash when changing sequences (for projects with SETTINGS > CV IN > TRACK X = CV/GATE AB or CD)
● Save As: fixed a bug making Hermod to crash when saving with a long project name.
● New Project: now, every project parameters are reset to initial values after selecting NEW PROJECT.
● Slave mode: fixed a bug making Hermod to play (start) only if songposition was at the very beggining, when slaving Hermod with a DAW.
● Overall stability and timing precision improvements.

Bug fixes

● Hermod tempo always had a 2BPM offset
● Hermod freeze when playing with the ModMatrix parameters
● Hermod freeze when randomizing a pattern on a modulation track
● Sync problem when slaving Hermod with another Hermod via USB, and loading or saving a project on the "master" Hermod
● CV OUT frozen value on a modulation track, when "mod range Max" or "mod range Min" (MIDI FX) is changed
● SEQ mode: when LOOP = FULL, Hermod never jump to the next selected sequence
● COPY/PASTE SEQ: ModMatrix parameters was not paste

hermodOS V1.021
april 25, 2018

Bug fixes

● Analog clock is now sent only when Hermod is playing.
● Fixed an issue making midi slaved instruments to not start from the beggining after a PLAY (when Hermod was midi slaved).

hermodOS V1.02
april 23, 2018

Bug fixes

● When muting an LFO, modulation signal wasn’t going through, it is now solved. Square and S&H were blocking earlier modulation, it is now properly going through.
● When saving and loading a project, Cv clock output was hanging, it is now properly going through.
● Greatly improved internal clock accuracy (from ~0.5% to ~0.07%).
● The hold timings was causing some issue with the play buttons. The timing is now a little longer and the handling process was improved.
● Accessing BPM know works seemlessly
● The reset CV input previously only worked with CV clock, it now works with each clock mode.
● Changing sequence or loading a project wasn’t reloading the modMatrix properly, it is now solved.
● When launching REC with the sequencer stopped, the held note are now correctly recorded.
● In restart playback mode, when a song is running, each sequence will now restart from the beginning.
● In sequence mode, a “full” setting was added to loop length (just before 1). The loop length is set as the longest track length of the sequence.
● Now you can change the loop length without deleting the chain.
● General stability improvement.

Bug fixes

● Fixed an issue with MIDI implementation that would cause problem with some device (Octatrack among others)
● Improved CV clocking stability
● CV clock reset now works properly
● Changed the behaviour of the play button while CV clocked: you can now start/stop the sequencer manually (you also need to start the sequencer manually)
● Fixed some UI bugs (MIDI effect wasn’t showing properly)
● Fixed a bug with the Euclid effect
● Added “RAND” waveform tothe LFO effect (S&H)
● When recording CV input, very short pulses were ignored (Rene in snake mode for example), it now works properly.
● You can now delete a project!
● When a track is emptied, it is now auto-unmuted
● The MIDI output effect now correctly sends note off when a sequence change occur
