PyraOS 3.0
august 24, 2018

New features LIVE mode
  • SCALE + CHORD INVERSIONS FIX: Some scales and chords were wrong, we fixed it, and fine tuned a lot of smartpad chords to make them work together.
  • New smartpad mode: CUSTOM CHORD.
  • Note/chords interaction between LIVE and STEP mode, with the setting MISC > LEARN NOTES = MIDI IN + LIVE.
  • POLYMETRIC LOOPER: now, you don't have to STOP Pyramid to record a new pattern with the looper and its countdown. It's a great way to create polymetric patterns (different track lengths) on the fly.
New features STEP mode
  • STEP DUPLICATE: hold TRACK+LENGTH and press < or > to duplicate or divide the track. For example, if your track is 4-bar length, holding TRACK+LENGTH and pressing > will duplicate the track to an 8-bar length pattern. Notes, FX and CC automation will be pasted.
  • Time signature and bar display: when the time signature is different than 4/4, Pyramid now displays on the piano roll a dotted line, showing the start of each bar (measure). Moreover, in stepmode NOTE, you can hold the pad eSTEPS to display on the 16th leds the start of the bar (high luminosity) and the start of the other beats (low luminosity). You can also hold the pad eFILL to only display the start of the bar.
New features TRACK mode
  • CONSOLIDATE: On any track, you can "consolidate" the effects, in order to write down the notes + CC messages computed. To consolidate a track, press 2ND+TRACK and select CONS. Then select the destination track with the menu encoder (can be the current track, or an empty track).
New features PATTERN mode
  • Now, press STEP+TRACK to enter the PATTERN MODE, instead of holding TRACK and rotating the menu encoder.
New features SEQ mode
  • Press DISP to display all active tracks in the current sequence. A list will also display up to 5 active tracks names + pattern number.
  • If Pyramid is playing a chain of sequences, press REC to loop the currently played sequence (the sequence will keep until you press again REC, or you restart Pyramid by pressing STOP and PLAY). Press 2ND+ < or > to jump to the previous/next sequence in the chain.
  • Now, you can copy/paste sequences (it will copy the track's mute states).
New features EFFECT
  • Now, you can add up to 5 effects per track. Quantize is now always present on slot 1. Its Default grid can be configured in SETTINGS > MISC > DEFAULT QUANTIZE, so you can decide to power on Pyramid and get a quantize active on each track, very handy for live performances.
  • FX LFO new parameter: OFFSET (set the LFO central value).
  • New QUANTIZE parameter: LEGATO. Allows to lengthen (a few ppqn) all notes of the tracks, and create a glide/legato effect on some mono synths. Useful when you record a performance in LIVE mode, but the recording do not preserve the legato of your performance.
  • New ARPEGGIATOR styles: 15 new great styles (DOUBLE, OCT UP, OCT DOWN, DRUNK, FIFTHS, ONE TWO, SILENCE, RUNNER, DISCO, MARBLE, RHYTHM 1/2/3), all working as the ASSIGN style (the note arrangement follows the playing order of the input).
  • New RANDOM parameter: OCTAVE, randomizing the octave of the note pitches.
New features ASSIGN
  • ASSIGN PER TRACK/PROJECT: Now, it's possible to assign the touchpad, the 5 encoders and the analog inputs per track. Each track will have its own set of assignations. Enable it SETTINGS > MISC > ASSIGN TYPE = PER TRACK.
  • New assign option: EFFECT MASTER: now you can change (with a single control) the Quantizer GRID, the Scale SCALE, the Scale KEY, the Chance CHANCE, or the Swing PERCENT of all tracks.
  • NEW TOUCHPAD POPUP: new display when the touchpad is assigned.
New features SYNC/CLOCK/BPM
  • ANALOG SYNC (Pyramid uses an external analog clock coming from a CV input, or with a pedal footswitch): Enable analog CV sync with SETTINGS > CV/PEDAL > CV IN MODE = CLOCK (or enable pedal sync with SETTINGS > CV/PEDAL > PEDAL HOT = CLOCK). Set the number of beats (or PPQN) the player will move forward each time Pyramid receive a clock with CV/PEDAL > INPUT SYNC. Select the tempo with BPM. Start the sync with an analog gate on the CV input (or by pressing your pedal). If SETTINGS > CV/PEDAL > CV IN MODE = CLOCK+STOP, use the GATE input to receive an analog STOP/PLAY (low state = STOP, high state = PLAY).
  • SEND CLOCK WHEN LOADING A PROJECT (to keep the sync with your midi instruments expecting clock from Pyramid): enable SETTINGS > MIDI OUT > SYNC LOAD = SEND CLOCK. Load a project: the clock will be sent during the loading. Your external instruments (eg a drum machine with an internal sequencer) will keep the sync. SETTINGS > MIDI OUT > MIDI A SYNC or MIDI B SYNC must be enable on the previous and next project. When loading is done, press PLAY: Pyramid and your outboard instruments will start to play from the beginning, allowing you to keep the perfect sync. When pressing PLAY after a load, will wait for the next bar to start the playback.
  • To not load the new BPM of a project, and so avoiding a BPM jump between two projects, hold 2ND while selecting a project to load.
  • CLOCK TIMEOUT: new SETTINGS > MIDI IN > CLOCK TIMEOUT = SHORT / LONG : When Pyramid lost the input midi clock, Pyramid will stop expecting external clock after 2 seconds (SHORT) or can wait 10s for an incoming clock (LONG).
  • At Pyramid startup, if a xxx.txt file is present inside the SD card root, Pyramid will load the file definitions. To enable this feature : SETTINGS > MISC > LOAD DEFINITION = ON. Pyramid will display the name of the CC (e.g. FILTER) if your current track has the same CHANNEL and OUTPUT as the instrument definition.
  • In the same way, you can also create NOTE definitions, in order to rename some notes (e.g. renaming C2 = “KICK”, D2 = “KICK”, …).
  • If an instrument's CC number is not contained in the .txt file, Pyramid will not display it in the CC messages list, allowing you to filter unused CC messages (only if SETTINGS > MISC > LOAD DEFINITION = FILTER CC). If an instrument's NOTE number is not contained in the .txt file, Pyramid will not display it in the piano roll, allowing you to filter unused notes (only if SETTINGS > MISC > LOAD DEFINITION = FILTER NOTE).
  • CALL INSTRUMENT: On any track, you can "call" an instrument (defined in the .txt file). It will auto-set the track name, the track channel and the track output. Press 2ND+TRACK to enter the track options menu, and select CALL. Then select the instrument you want to call in the list. Up to 16 instruments can be created. If an instrument is not defined, “...” will be displayed.
  • TRANSPOSE IN SYNC: new SETTINGS > MISC > INPUT SYNC = OFF, BEAT, 1 BAR, 2 BAR, 4 BAR : To delay a forthcoming transposition (when using a midi controller to transpose your selected PTRN tracks), enable this setting. The transposition of your tracks will now happen in sync (each BEAT, 1 BAR, 2 BAR, 4 BAR).
  • ANTI ECHO AUTO: Enable it with SETTINGS > MIDI IN >MIDI ECHO = AUTO MIDI A or AUTO MIDI B (depending on whether the midi loop is on output A ou B). Midi events received on the MIDI input will be ignored if they were previously sent on MIDI A or MIDI B, to avoid midi loops. It works differently than the MIDI ECHO = OFF, which is designed to simply not send the MIDI input events to the MIDI outputs.
  • PYRAMIDI: To mute/unmute a track (from TR01A to TR16D), you can use incoming CC messages (from CC1 to CC64) when SETTINGS > MIDI IN > PYRAMID is enable. If value = 0, the track will be muted. If value = 1, the track will be unmuted. If the value = 127, the track mute state will toggle.
  • 0.32V/OCTAVE: new SETTINGS > CV/PEDAL > CV OUT TYPE = 0.32V (for EMS Synthi users).
  • SETTINGS > CV/PEDAL > ASSIGN ENV OUT = START : Send a start level (high level) when Pyramid is playing, and send a stop level (low level) when Pyramid is stopped. SETTINGS > CV/PEDAL > ASSIGN ENV OUT = START + DIN SYNC : Same a the START parameter, but also send the din sync clock on the GATE output.
  • Now you can import TYPE 1 midi files in Pyramid to create a multi-pattern track.
  • New setting CV/PEDAL > PEDAL HOT/COLD > FREEZE SEQ (Now you can loop the running sequence if SEQ mode = PLAY and you have a chain of sequences. Same feature as pressing REC in SEQ mode).

  • CC message stepmode is now the last stepmode: now it's easiest to enter stepmode CC messages
  • Prelisten a CC message: in the stepmode CC message, press the menu encoder to listen the dotted line value.
  • FX and CC logos when you scroll DISP view: each time you select a new CC message or a new FX parameter in the both stepmodes, a logo popup will appear, for a better navigation.
New features TRACK mode
  • Instant mute/unmute: Select if tracks mute/unmute are in sync with SEQ PERFORM (inst, beat, 1bar, 2bar, ...) or always instant with SETTINGS>MISC>TRACKS MUTE
New features SEQ mode
  • Sequence shorter that 1 bar: you can now set a sequence in the chain to be shorter than 1 bar (e.g. 1/4 bar = 1 beat, 2/4 bar = 2 beat, ...).
New features EFFECTS
  • FX Scale: this effect quantizes all note pitches to a defined scale in real time, to refine your melody.
  • FX Delay: this midi delay creates a copy of the original notes, simulating a normal delay effect, but using the velocity midi data.
  • FX Equalizer: this effect increases or decreases note velocities, according to the note pitch.
  • FX BPM: this effect enable you to create global tempo automations.
  • FX Note to CC: this effect converts a note parameter value (note pitch or note velocity) to a selected CC message (or to the midi "pitch bend", "aftertouch" or " program change").
  • FX Chance: this effect adds a probability to play a note or not. It's a great way to add variations to drums or melodies.
  • Quick EFFECT MANAGER selection: in the main EFFECT MANAGER window, press encoder 1 to enter the effect in slot 1. Press 2ND + encoder 1 to enable/disable the effect in slot 1...
New features ASSIGN
  • Assign a CC to GLOBAL: when assigning an encoder to a CC message, a new option appears: GLOBAL. That means that the CC messages will be sent on the channel of the selected track, instead of always being sent on the same channel.
  • Assign touchpad to smartpads: when assigning the touchpad, a new option appears: SMARTPADS. Now you can play the touchpad X axis to send chords (if the LIVE smartpads = CHORD) or scaled notes (if the LIVE smartpads = SCALE). You can also select the smartpads octave range (1, 2, 3 or 4 octaves) and the parameter controlled on the Y axis (note velocity, aftertouch, pitch bend or modulation wheel).
Other new features
  • BPM elastic shift: hold 2ND+BPM and slide the touchpad X axis to temporarily shift the tempo up or down. Very handy to manually syncing Pyramid with an external sound source (for example a turntable).
  • BPM double/divide: hold BPM and press < or > to double or divide the BPM in a flash.
  • Delete projects: in the LOAD project list, press 2ND+DELETE to remove a project definitively from the SD card (note: the backup project is not removed).
  • Default track settings applied on empty tracks: when you change track setting in SETTINGS>MISC (DEFAULT TRACK, DEFAULT ZOOM, DEFAULT LENGTH, DEFAULT TS, DEFAULT PERFORM), new track settings are applied directly on empty tracks. You don't have to restart Pyramid anymore.
  • Do not send midi clock when Pyramid is paused or stopped: new setting (SETTINGS>MIDI OUT>CLOCK STOP) to not output the midi clock message when the player is stopped or paused.
Last but not least
  • Bug fixes
  • More RAM memory, better CPU performances
  • Graphical improvement
  • Better led states

  • Automation step-lock style (hold a step, rotate the menu encoder).
  • Automation drawing with touchpad (hold REC, slide the touchpad).
  • Simply press ASSIGN to activate the "Encoder step edit" feature.
  • "Encoder step edit" feature improved, now works with the touchpad.
  • Mute/unmute tracks are now in sync (depending on the PERFORM option in SEQ mode).
  • Save sequence mute states on/off (press REC in TRACK mode).
  • TRACK mode DISP view improved, leds flashes when tracks send midi events.
  • Beat progression and sequence progression in SEQ mode.
  • Assign CC MESSAGES or FX PARAMETERS to analog inputs (hold assign and plug a jack into CV in or GATE in).
  • PYRAMiDi implementation chart, to control Pyramid with an external controller.
  • SAVE settings and SAVE track channels (accessible via SETTINGS menu).
  • Metronome ON/OFF (press 2ND + REC).
  • New I/O pictograms: CV in, CV out, USB in.
  • Default track parameters loaded at startup (zoom, length, time signatures) in SETTINGS > MISC.
  • Now you can play with an external keyboard (midi in) and change modes (LIVE, STEP, TRACK, SEQ) without stopping the external keyboard notes events.
  • You can now assign the ENV CV output to the din sync clock, to easily sync your modular system with a mini jack (SETTINGS > CV/PEDAL > ASSIGN ENV OUT > DIN SYNC).
  • You can now send the din sync clock only when the player is playing.
  • Better led brightness and states.
  • You can now scroll the track banks (tr01A>tr07A, tr08A>tr16A, tr01B>tr07B, ...) in TRACK mode DISP with the main encoder.

PyraOS 0.84
december 23, 2015

New features
  • In NOTE stepmode, you can now select the current note with a midi IN external keyboard: press a key while pressing the menu encoder to set the note (for example C3#).
  • USB midi in implementation: Pyramid is now able to receive USB midi messages: sync clock, start/pause/stop, notes, CC messages, pitch, aftertouch (same operation as the midi IN).
  • External clock mode recast, Pyramid now follows with a very low latency the tempo, without drifting. Better handling of start/pause/stop messages. Works perfectly with a master DAW, a master sequencer, an other Pyramid...

PyraOS 0.83
november 13, 2015

Graphic improvements
  • New project header
  • On all 4 modes, Pyramid now displays the current sequence and the next sequence to be played if there is one.
  • COPY pad, PASTE pad, DELETE pad and UNDO pad now blink to indicate the action is done.
  • New popups for assigned encoders (when clicking an assigned encoder).
  • Disabled effects in FX manager are now grey tinted.
  • Chord DISP: displays the piano roll on stepmode CHORD. Rotating the menu encoder allows you to move to the chord root note.
  • In CC MESSAGES stepmode and EFFECTS stepmode, a grid is displayed to help you to edit automations.
  • Notes exceeding the current page on the piano roll view are now displayed on the next page too. (stepmode NOTE and CHORD)
  • TRACK mode now displays the content of a track, either it is NOTES, EFFECTS, CC automations or FX automations.
New features STEP mode
  • Stepmode selection list is not circular anymore.
  • When changing the stepmode, passing over “EUCLID” no longer mutes the track.
  • Hold 2ND and press ASSIGN to enter the “5 encoders shortcuts” mode: in step mode, encoder 1 will control EUCLID STEPS, encoder 2 will control EUCLID FILLS, encoder 3 will control VELOCITY, encoder 4 will control LENGTH, encoder 5 will control OFFSET. When filter mode is activated, you can't use the 5 encoders to control CC messages and effect parameters. Exit this mode by pressing ASSIGN.
  • Filter mode: in stepmode NOTE and stepmode CC MESSAGES, double tap STEP to activate the filter, in order to scroll only through programmed notes or CC messages. double tap STEP to exit the filter mode.
  • Program Change midi messages are sent only if they was not sent before, to avoid sending them at each beginning of the loop. If you press 3 times STOP, Pyramid will resend all Program Changes of tracks, useful to be sure that all your PC are sent before playing a project.
  • In CC message stepmode, the default current CC value is now the first value set, instead of “0” (if an automation exist).
  • In stepmode CHORD, hold 2ND and rotate the menu encoder to select the tonality.
New features TRACK mode
  • BPM is displayed only if you press the BPM pad.
  • Configure tracks run modes: While in track mode, hold TRACK and rotate encoder menu to select the running mode (FREE, RELATCH, TRIG):
    FREE (no icon displayed under TR, default mode): when a new sequence starts, if the track was active in the last sequence, this track continues to play without restarting at its beginning. In other words, track keeps playing from its last position, useful for get the best out of polymetrics: tracks shift against each other.
    icon displayed under TR): when a new sequence starts, the track always restarts at its beginning. It's an easy way to sync your tracks.
    TRIG (
    icon displayed under TR): track is playing once at the beginning of the sequence, and does not loop. The track is simply triggered.
New features SEQ mode
  • SEQ mode: choose to PERFORM sequences (launch sequences after the selected number of bars or instantly), PLAY sequences (sequences arrangement will stop at the end of the chain) or LOOP sequences (sequences arrangement will loop at the end of the chain)
  • Now you can copy, paste & delete sequences.
  • When you add a sequence in the chain, Pyramid now displays the full length of the sequence. It's the number of bars after which all tracks are sync again, if using different track length. For example a sequence with a 3 bars length and a 4 length had a full length of 12 bars.
New features Save/load mode
  • Saving an existing project creates a backup file in the SD card, for example “BACKUP_PROJECT1”, to always keep an old version of your project.
New settings
  • Settings > Midi Out > Midi A Mode (midi out, midi thru, midi out + thru): select the behavior of midi A output port
  • Settings > Midi Out > Midi A Mode (midi out, midi thru, midi out + thru): select the behavior of midi B output port
  • Settings > Misc > Double Tap Mode (velocity, glide): in NOTE and CHORD stepmodes, double tap a pad to enter velocity accents or gliding notes. Glides only works with compatible synths, if two notes follow, the first one need to be double tapped to create a glide between these two notes).
  • Settings > Misc > Rec Countdown (off, current track, midi channel xx): activate a countdown before a recording in live mode, and choose on which midi channel the countdown (made with midi notes) is generated.
  • Settings > Misc > CC Assign (autorec off, autorec on): with autorec on, as soon as you assign a CC control and move it to set the value, an automation message is created to store this value (you can display it or remove it in stepmode CC MESSAGES). This message will be sent at the start of the track, so your synthesizer will always have the right set value.
  • Settings > Misc > Play pad (pause/continue, restart): If play/pause selected, a press on the PLAY pad will alternately play and pause the playback. If restart selected, a press on the PLAY pad will always restart the playback from the beginning.
  • Settings > Misc > Default track (mode free, mode relatch, mode trig): set the default run mode of new tracks.
  • Settings > Misc > Popup Assign (on click, on rotate): to display the assigned encoder popup when you click one of the 5 encoders, or when you rotate it.
  • Settings > Misc > Touchpad Relatch (no relatch, relatch value): if no relatch selected, the touchpad (assigned X or Y position) will keep it's last set value. If a value is selected (for example 0), the touchpad will send back this value when the touchpad is released.
