- New: Mx and A/B Output options— Setup programmable or derivative Trigger/Gate Sequencers from Mod Lanes!
- A/B Outputs > Mod Trig — Derives Trigs from a selected Mod Lane.
- Mx Outputs > Mod Gate and Mod Trig — Derives gates and trigs from all 8 Mod Lanes for output on the Gx/Qx or via MIDI CC/Note.
- Setup > MIDI Mx Ch — Duplicated for easy access from Mx page.
- Setup > MIDI Mx Output: CC or Note — You can now output MIDI Note messages derived from the Mx outputs; use these to Trigger midi devices.
- Note: Triggers are 10ms long, and gates will tie at the initial value until a following stage goes low.
- Tweak: Mx Stage Num options, now only output when the sequencer is running.
- Tweak: Play Mode swaps (via param or modulation) now apply when the stage advances, and will reset when it's swapped. This leads to much more predictable behaviour since almost all of the play modes are non-linear in nature.
- Fixed: Delayed modulation (by a pulse) of position/play mode related mod destinations.
- Fixed: Incorrect position/play mode modulation applied on the first pulse after a Reset.
- Updated manual available at intellijel.com/support.
10 releases since Feb 2022, roughly one every 6 months.

Version 1.6.2.0 — 23 Oct 2025
- Fixed: Loopy ends up in an odd state if RUN was toggled off while holding down some stages.
Version 1.6.1.0 — 29 Sep 2025
- Fixed: Preset Chain Mutes stopped working in 1.6.
Version 1.6.0.0 — 24 Sep 2025
- New: Set the Root Note with a MIDI Note On Message.
- New Global Setting for setting the "MIDI Root Ch."
- Changes the Root Note Setting to the last received Note on the specified MIDI Root Channel.
- Since we are changing the setting, the latest changes will be saved to state and when you save a preset.
- Does not affect Custom Scales, since they are configured with their own specific root note.
- New: Load Presets with MIDI Program Change messages.
- New Global Setting: MIDI PC (Program Change) Ch.
- MIDI program change messages 0-63* will select Metropolix presets 1-1 to 8-8 (bank-slot) on the configured channel.
*Note: Your software or device may display the program numbers as 1-64.
- Presets will be loaded according to the Load/PC Delay option on the Preset Load screen.
- Program Changes will be ignored if a Preset Chain is running, or the Preset does not exist yet.
- New: Immediate RESET/RUN behaviour.
- RUN and RESET now happen immediately when the button is pushed. The old Click/Hold-Release behaviour has been removed.
- Internal clock: RUN will start immediately, resetting the phase of the internal clock.
- Internal clock: ALT+RESET will Reset immediately, also resetting the phase of the internal clock.
- New: "Reset Input" mode, "Run-C" or Run-Continue. Which does not Reset the sequence when the input signal goes low. You can use the RESET button for a manual reset.
- Tweak: When Root is assigned to a CTRL knob, the range is ±12 Semitones instead of ±11, allowing you to reach the next octave.
- Tweak: When Root modulated via AUX or MOD Lane upwards beyond +1 octave (>=1V), the root note will wrap at 1 octave higher, similarly when you modulated downwards beyond -1 octave (<=1V), the root will wrap around at an octave lower.
- Tweak: No "Pitch Pop-up" when you are on the "Pitch" Home view, allowing you to dial in and see all the stage pitches as you adjust them.

Version 1.5.3.0 — 4 Feb 2025
- TWEAK: USB Product ID Updated.
Version 1.5.2.0 — 17 May 2024
- FIXED: Gx/Qx/Mx was not working in 1.5.1.0.
Version 1.5.1.0 — 16 May 2024
- NEW: Support for the Metropolix Solo w/ TRS MIDI Jacks via i2C port.
- Enabled by default. All MIDI settings also work with USB.
- TRS MIDI support is disabled when a Gx or Qx are connected.
- NEW: Mx Expander settings can now be output as MIDI CC.
- By default Gx MIDI Channel is Off.
- Gate Outputs 1-8 corresponds to CC 102-109 on the Channel selected on the Mx Setup screen.
- Mx Screen has a new param for setting MIDI Channel (set with ALT).
- NEW: Updated Default Track Options:
- Velocity: 100%
- Track MIDI Channels:
- Track 1: MIDI CH 1
- Track 2: MIDI CH 2
- Track CCs:
- CV to CC: CC #1
- Slide* Toggle CC #65
- Slide* Amount CC #5
- (*NOTE: Slide config matches Cascadia defaults)
- NEW: MOD Lane MIDI Defaults:
- MIDI Channel for all MOD Lanes: CH 1
- MOD Lanes 1-8 CC Values: 20-27
- Track 1: MIDI CH 1
- Track 2: MIDI CH 2
- Track CCs:
- CV to CC: CC #1
- Slide* Toggle CC #65
- Slide* Amount CC #5
- (*NOTE: Slide config matches Cascadia defaults)
- NEW: Unipolar/Bipolar CV options on the CV TYPE screen for setting CV display to either Unipolar, Bipolar, or Gate Toggle. The CV Type is set per-Lane, so it can be set individually for each MOD Lane and for the CV Lane in a Track. To access it:
- Press ALT+CV (Stage 8) to display the CV TYPE screen.
- Note: If a MOD Lane is assigned to an internal parameter, then the MOD Lane type will follow that selection, either: Bipolar or Gate.
- Note: If Track CV is also assigned to Track Velocity, then the CV Type will be forced to Unipolar (for Setting Velocity directly), or GATE (for Setting Accent toggle style).
- NEW: CC value display on the Stage Edit screen for Track CV and Mod Lanes:
- Values are still entered as Voltages (or in the case of Mod Lane, based on the parameter ranges). But you can see the CC value that will be sent if you also have the lane assigned to CC.
- NEW: SCALES can now be copied & pasted to user (custom) scale slots.
- Copy: Press ALT+SCALE on ANY scale.
