Quadrax

Entering Bootloader

1. Turn off power to your modular system.
2. Connect a USB cable from the rear of the module to your computer.
3. Hold down the top left CV A button and top right RISE button and turn on power to your modular system.

Changelog

1.4.5.0 (2026-08-10)

• NEW: 2 New shortcuts—
  1. Return Home
     Long-press both Channel 1 and 2 MODE buttons (top 2 buttons on the right) to exit any alternate view (like CV Assign or Utility) and return home to the standard operating mode.
  2. Clear All Channel Settings and Return Home
     Long-press both Channel 3 and 4 MODE buttons (bottom 2 buttons on the right) to clear the current channel settings, modes, scaling and modulation assignments for all channels. This will also exit any view and return to the standard operating mode. Note: This shortcut will not clear any SYSTEM MODE options that you may have set, only the parameters available under normal usage.
• Updated manual available at intellijel.com/support.

1.4.1.0 (2025-05-27)

• FIXED: LFV Freezing up at with extreme modulation.

1.4.0.0 (2023-04-27)

• NEW: In Utility Mode, the sync LEDs now flash with a trigger.
• NEW: CVD (Colour Vision Deficiency) Mode.
• Updated manual available at intellijel.com/support.

1.3.1.0 (2023-03-28)

• FIXED: EOR on Qx/Gx is now before the S stage (in ASR) at the end of Rise.

1.3.0.0 (2021-10-05)

• NEW: Utility UI Mode (Hold RISE + LEVEL for 1 Second to Toggle). The left buttons will manually trigger a channel; the right buttons will set (5 or 10V) and attenuate (20% Increments) the channel's output level.
• REMOVED: 10V/5V Envelope size global toggle. Replaced with per-channel setting in Utility Mode.
• FIXED: Phase/Clock Sync abnormalities in LFV Mode.
• Updated manual available at intellijel.com/support.

1.2.1 (2021-03-09)

• CHANGE: Envelopes are linked via gates, not trigs. Allows triggering of AHR envelopes by linking to a previous envelope.
• CHANGE: Reduced size of pot dead zone.
• FIXED: Slightly longer minimum attack and decay times. Fixes modulation of some waveform types when at minimum.
• FIXED: LFOs not clock syncing in some cases.

1.2.0 (2020-11-19)

• NEW: Phase sync for clock-synced LFOs. See manual for details.
• CHANGE: Various optimizations, reduced latency.
• CHANGE: Sharper minimum attack and decay times.
• CHANGE: Add 5% dead zone at end of pot travel to account for component tolerances.
• CHANGE: Remove crossfade at the extreme ends of one-shot mode 1. Instead the waveform just switches from square to sine.
• FIXED: Fixed initial phase of one-shot mode square waveforms.
• FIXED: Improved trigger detection.

1.1.3 (2020-03-03)

• FIXED: Some settings may not have carried over correctly when the firmware was upgraded from 1.0.2 or earlier.

1.1.2 (2020-02-25)

• FIXED: Edge case where CV assignments are not being applied.
• NEW: Long press LEVEL button when in System Mode to reset module's settings to defaults.

1.1.0 (2020-02-06)

• NEW: Replaced original burst mode.
• NEW: Alternate modes for each mode.
  • AR/ASR/Cycling AR: Mirrored Rise/Fall Curves.
  • Burst: Tilting saw shape instead of sine/square crossfade.
  • LFO: Low Frequency Vacillator — Drifting chaotic voltage source.
• CHANGE: More extreme log/expo curves.
• CHANGE: 10V is the new default Envelope size.
• NEW: System Mode for system toggles like envelope size.
• FIXED: Distorted expo/log curves.

1.0.2 (2019-12-19)

• FIXED: Added toggle for dithering to remove "quantize error noise" from outputs.

1.0.1

• Initial release.
