hermodOS V1.60
August 12, 2020

New features
  • TRACK LENGTH 1/16th notes (instead of 1/4): now the polymetric resolution goes up to a sixteenth note! When changing the track length, hold the encoder to add/remove a sixteenth note to the length.
  • SEQ LOOP 1/16th AND MORE: in SEQ mode, the LOOP length parameter can now be set to additional "SHORTEST", "LONGEST", and "TRACK X" lengths. Furthermore, for the more traditional fixed length LOOP length, the length resolution now goes up to a 16th note. Press and hold the encoder when changing LOOP to add/remove 1/16th notes.
  • MODMATRIX ATTENUVERTER/OFFSET: every modulation input can go through an attenuverter / offset stage. Buttons ① ② ③ ④ give you access to the normal modulation input/output, while ⑤ ⑥ ⑦ ⑧ show the attenuverter/offset stage for a given modulation.
  • STEP RANGES: in Step Mode, you can now select step ranges. For example, press ① and ④ to select all events from ① to ④. Pressing ① and ⑧ selects the entire page. To select every event, across all pages, press [STEP] and ⑧.
  • MOD CC ROUTING: Mod CC is now routed both to the track and the modmatrix
  • QUANTIZER: new options to allow triplets (1/24 and 1/12)
  • BETTER DAC CALIBRATION: (note that this new firmware is not compatible with your last DAC calibration, you will have start a DAC calibration again).
  • NEW ADC CALIBRATION: hold Y at startup. Select the input to calibrate (A, B, C or D) with 1, 2, 3 or 4. Rotate the encoder to fine tune the ADC voltage. Press the encoder to select the voltage to calibrate, from -4V to +4V (tips: the 8 CV OUT always output the selected voltage). Save this calibration: press X.
  • RANDOMIZER: each track now has its own set of parameters
  • MOD TRACK: it's now possible to delete only gates
  • ENCODER ACCELERATION: scrolling the encoder fast will change the parameter faster (enabled modes: STEP note values & track length edit, EFFECT edit, Attenuverter)
  • PHONE KEYPAD STYLE: while editing the project name, you can press repetitively pads 1...8 to jump and select characters (A..D, E..H, I...L, M...P, Q...T, U...X, Y...0, 1...9)
  • SAVE AS now suggests the last used project name
  • CURRENT TRACK of the project is now saved and loaded
  • LZX CV: You can now configure whether a track outputs a CV range of -5V to +5V (1V/octave), or -1V to +1V (to follow the video synthesis CV standard, used amongst others by LZX industries). These options are placed under settings > misc > cv out. Also added, settings > cv/gate in > cv in range = -1 > +1V, in order to record properly this new CV standard.
Bug fixes
  • CC64 was sometimes erroneously recorded in a sequence

Bug fixes
  • First note was sometimes skipped after a sequence change
  • Delay effect sometimes got stuck at fast rates
  • Muting and unmuting multiple Swing effects sometimes caused stuck notes
  • LFO in synced rates started out of sync then snapped in sync, when Hermod used an external MIDI clock
  • Euclid effect was synced on upbeat (instead of downbeat)
  • Randomizing a short pattern sometimes caused fatal error (freeze)
  • Randomizing a pattern disabled scrolling between pages
  • Randomizing a MOD layout track deleted the user-added gates
  • Adding an ARP effect before a RAND effect sometimes caused stuck notes
  • Replacing a RAND effect by a SCALE effect sometimes caused stuck notes
  • Loading a new project did not reset the song sequence
  • When selecting a step and immediately rotating the encoder, the page was changing instead of the note value
  • After loading a project with a clock source not internal, the display was not updated correctly
  • Sequence chain position was not reset after a STOP
  • Modulation tracks kept sending user-added gates even if the gate output was assigned as a CLOCK OUT
  • Midi input "learn" was not updating the note parameters (pitch & velocity) when the midi channel was not set with ACTIVE TRACK.

  • MIDI CC 64 (sustain pedal) is now recorded during a performance, and can be forwarded to MIDI devices with the MIDI OUT effect
  • MIDI effect now has an 'Apply sustain' parameter. This holds NOTE OFF messages when CC64 is high, and releases them all when CC64 goes low (turning this ON consumes CC64 messages)
  • Hermod can now be synchronized in a "step advance" (trigger) style, thanks to the setting CV TRANSPORT = A/B/C/D TRIG. The setting CLOCK IN DIV let you choose how much time the sequencer will run for 1 input trig, from 1/32 note to 1/4 note). Please note CLOCK SOURCE must be set to INTERNAL to use this mode.

  • New shortcut STEP mode: hold STEP and press X to delete all events of the current track
  • New shortcut STEP mode: hold STEP and press Y to randomize the current track
  • New shortcut STEP mode: hold STEP and press a pad (1 to 8) to quickly set a note length (1/8 to 8)
  • New shortcut STEP mode: when holding a step and editing its note value, rotate the encoder while pressing it to enable fast scroll (works also for the velocity value)
  • New shortcut STEP mode (MOD track): long presses on STEP toggles between the MOD and GATE edit submodes
  • Simultaneous notes limit was increased from 8 to 16 per track
  • MIDI CC1 (modwheel) can now be used in the modmatrix, when not used as a mod input in the MIDI effect

hermodOS V1.3
april 2, 2019

New features
  • REC WAIT/LOOPER : press X+REC (only if Hermod uses its internal clock) - if Hermod is stopped, it will wait for you to play a note before starting to play and record (punch in).
    - if Hermod is already playing, it will wait for the next bar to restart the player and enable the recording.
    - pressing REC again will end the recording and will set the track length to the recording time, like a looper (from 1 bar to 16 bar).
    - tip: pressing X+Y+REC will enable the looper with hard recording.
  • MULTITRACK RECORDING: press STEP+REC to enable multitrack recording (omni mode). Up to 8 routed tracks (via midi in, usb in, cv/gate in, ...) can be recorded at the same time.
  • RESTART: press SEQ+PLAY to restart (re-sync) all tracks.
  • New SETTINGS > CLOCK > CV CLOCK OUT (G1+RUN, G2+RUN, G3+RUN...). If set, the CV voice will output 5V if Hermod is playing and 0V if Hermod is stopped.
  • New SETTINGS > CLOCK > CLOCK SOURCE (TRANSP OFF). If set, the clock will be internal but Hermod will not send transport midi messages (CLOCK, START, STOP, ...) to the midi/usb host/usb device outputs.
  • New SETTINGS > MIDI IN > PROG CHANGE (OFF, ALL, 1, 2, 3, ...16). Now you can select the channel of Program Change midi message (in order to switch between sequences).
  • New LFO RATE values, to make it slower : 6/1, 8/1, 16/1, 32/1, 64/1, 128/1.
  • FX SCALE : TRANSPOSE range increased (-36...36 instead of -12...+12).
  • Autoload template project : if you name a project as "_", it will always be loaded at startup, even if you saved or loaded an other project more recently, making it easier to have a template project.
Bug fixes
  • Freeze when changing sequences while synced to an external clock, and receiving midi notes.
  • Freeze when generating patterns with the randomizer.
  • Improved delay when recording notes via the midi input.
  • When changing sequences (with PLAY+SEQ), sometimes, tracks were not reset to their beginning.
  • When assigning an effect parameter (modMatrix) to CVA, it was not possible to change the value in the effect view.
  • FX CHANCE was not playing the first note (if affected by sync chance).
  • When SETTINGS > CV IN > TRACK X = CV/GATE AB/CD, this input CV value was used to define the mid-value of the LFO effect (now you have to use only SETTINGS > CV IN > TRACK X = MOD A/B/C/D).
  • Now the LFO will not run when Hermod is stopped.
  • After loading a project, sometimes, MOD tracks were displayed as NOTE tracks on the screen.
  • Held note when using the FX MIDI OUTPUT and overlapping the same note.
  • FX MIDI : now if INPUT MOD is not set to CC1, CC1 can't control the modulation anymore.
  • HARD REC was not usable when the current track was set to MOD.
  • CV inputs (ABCD) accuracy greatly improved.

hermodOS V1.21
december 18, 2018

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

  • 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.
  • External clock: 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.
