How to update the Intellijel Multigrain

Turn off power to your modular system. Connect a USB cable from the rear of the module to your computer. Hold down the BOOT button on the rear of the module and turn the system power back on (the LEDs stay off in bootloader mode). Open the Intellijel Web Updater in a Chromium-based browser (Chrome, Edge), select Multigrain and click Update Firmware. Windows users may need to install the WinUSB driver via Zadig first.

Release notesopens in a new tab — intellijel.github.io

Version 1.4.7.0 — 9 Sep 2026

Fixed: Issue where the first 2 Grains of a Sound would use the same random value.

Version 1.4.6.0 — 24 Aug 2026

Fixed: Clearing Presets was only clearing in Bank X.

Version 1.4.5.0 — 24 Jul 2026

- New: System Page Option — SELECT CV Scaling Use WRAP on the System Page to scale your SELECT CV source, allowing modulation of Sounds 1-8 using a smaller voltage range than 0-5V, all the way down to 0-0.6666V (8 semitones). See manual for details. - Tweak: Increased sensitivity for Mod Out Envelope Follower options. - Tweak: Smoother/Finer Control handling. - Fixed: Very high pitch grains (+3 Oct via modulation) putting high demands on CPU/RAM, causing LED flickering, unresponsive buttons. - Updated manual available at intellijel.com/support.

Version 1.4.2.0 — 5 May 2026

- Fixed: Regression blocking parameters from being copied when saving a Live Sound to an empty Sample Sound slot.

Version 1.4.1.0 — 27 Apr 2026

- New: 2 New Per-Sound Options — Enable any combination of these. Note: the Blur effect is not choked or gated and will decay as expected. - Choke Sound Choke Sounds will cut off any existing grains when they are triggered. - Gate Sound Gate Sounds will instantly end any existing grains when the "gate" goes low; the "gate" can be the GATE input, holding the SOUND button down, or latching the sound. - New: Alt Page UI for Per-Sound Options: Live, Choke, Gate Note: The existing Home Page Toggle for Live Sounds (SOUND+SAMPLE) is still active. - Enter the ALT page and hold the SOUND button down to view or tweak that Sound. - The 4 LED Buttons in the Grain Section will change function while the SOUND is held to show and toggle the Sound Options. - SAMPLE will toggle Live (Toggle Live Sound) - LINK/LOAD will toggle Choke (This still stop any audio before this Sound is fired) - LINK/SAVE will toggle Gate (This will stop any audio when the gate on this sound is released) - REVERSE is currently disabled in this context - You can hold LATCH along with any SOUND to set these options for all Sounds - New Choke and Gate Sound options can be saved with the default Sound or default Live Sound. - These options are saved in your preset. - New: New MOD A/B Output Options - Threshold Gate (YELLOW) Follows the Record Threshold option, sends a gate when the input signal has passed the threshold; if threshold is disabled it uses the minimum value, this can be sensitive based on what is patched, just increase threshold if too sensitive. Try self-patching to GATE to have Sounds play only when incoming audio is received by Multigrain! Taking this further, you can also use it with the NEXT=RESET System option to re-align the playheads (to START) when new audio is captured. - Record Trig (PINK) - If Sampler: Sends a trig when Recording Starts, great for triggering modules and recording a 1 shot.

Version 1.3.3.0 — 5 Nov 2025

- Fixed: Random Mod not being applied to SHAPE or REVERSE. (Since 1.3)

Version 1.3.2.0 — 3 Nov 2025

- Fixed: Remove the Fine Tune offset (ALT+PITCH) from the MOD A/B Pitch Output option. - Fixed: Fixed rare/potential freeze (again) when a HIGH GATE was patched in on boot-up.

Version 1.3.1.0 — 30 Oct 2025

- Fixed: Module UI was being starved out when in certain conditions with pitch-up grains. - Fixed: "Default Sound" params will now save/load across boots. (You will need to set them again). - Fixed: Fixed rare/potential freeze when a HIGH GATE was patched in on boot-up.

Version 1.3.0.0 — 2 Oct 2025

- New: Collect and Save Presets and Projects — 3 Ways Collect any .wav files in the /Wavs and /Recs folders that are referenced in presets into the preset's /ProjectXX folder. Just like the "Collect and Save" on Bitwig or Ableton. If a matching filename exists in the project, it will be compared to the new one, and if it's the same file, the reference will be updated to the file already in the project without copying, otherwise a -1 (or -2, -3...) will be appended to the filename when it's copied (example Rec0420-1.wav). - Auto-Collect on Preset Save - Enabled from the System Page, see notes below. - When ON, any "external" sound references in the current state will be copied to the current project folder and the Sound references will be updated when a Preset is saved (even Quick save). - If all the sounds are already in the project, this action does not add any time to the save routines. - Manual Collect and Save a Project - Manually collect all the files for ALL the Preset and Autosave files inside a Project. - From the Projects Page, hold one of the 8 project buttons for 4 Seconds, it will flash quickly as it collects everything in that project, the SD LED should blink rapidly. - The Projects you've collected while on the Project Page will turn Green (this display will reset when you leave the Projects Page. - Collecting a project WILL collect and update "Locked Presets". - Manual Collect and Save for ALL Projects at once - Hold /PROJECT (X) on boot, until the bottom LEDs light up in blue, this will collect and save every preset in every project. - When it's complete, it will boot normally - This should allow you to delete/reset the contents of your /Recs or /Wavs folder, without fear of breaking any Presets/Projects. - New: System Page Settings — Something for everyone Note: these are system wide settings, and could affect how your presets sound when they are loaded. You can enter the System Page by holding ALT+REVERSE for 4sec. [...]

Version 1.2.3.0 — 20 Aug 2025

- Fixed: REVERSE and SHAPE parameters were being applied to the next grain rather than the current. (Regression from 1.2.1) - Tweak: Entering Sample Settings page used to freeze the recorder, now it does not. If you are using the Live Recorder, changing Live SIZE will clear and freeze the recorder, the original recorder state will be returned when you leave the Sample Settings page.
