2. Follow the instructions in the latest firmware zip file.

Firmware Release Notes

Open Beta V1.05 - Variations Update:

New features:

  • Evolve UI added to modulation pages, bringing 85 internal LFOs with unique frequency, wave shape, depth and a virtual VCA for each.

  • VCA added to the Macro/CV mod matrix UI. This allows the Evolve LFO’s VCAs output amplification to be controlled by Macro Pots or CV inputs.

  • PROB parameter added to main UI page 1 with per step, per channel options for full step or individual trigger probability of being sent.

  • * and ALL buttons now function within MOD pages for faster navigation and parameter selection. In the Evolve UI, ALL being active adds to or subtracts from all parameter’s values. In the Macro and CV pages, ALL being active sets the modulation range for all channels.

  • RESET button added to all modulation pages. Right click for 2 seconds on the reset button to reset all modulation values to 0.

  • Density can now be set to 0 to allow interesting modulation options starting from silence.

  • Blinking ALL and * indicators added to the MOD & uSD pages.

  • Added momentary or latching options for * and ALL buttons.

  • Persistent configuration added for BPM, SHUF, SH16, CLK, PPQN, * MODE, ALL MODE and BOOT Started/Stopped.

  • Updated the main UI page 3 with new configuration options.

  • 24 and 48 PPQN options added.

Fixes/Improvements:

  • Humanize range now limited to 127 for legacy preset comparability. 0-100 is the same subtle range while the new extreme ranges are mapped from 101-127.

  • Testing a new fix for Humanize dropped triggers in external clock mode.

  • Fixed an issue in which quantization nodes would not recall with presets after a power cycle.

  • Sample and Hold per step text changed from ‘0 or 1’ to ‘ON or OFF’.

  • Fixed LFO ignoring MINV and MAXV settings in Sample and Hold mode when trigger density is > 1.

  • Changed MINV & MAXV mod matrix * parameter change value from 1000 to 250.

  • Fixed an issue with Gate Length when Phase Shifting.

Open Beta V1.04 - Bug Fix Update:

  • Fixed an issue wherein the LFO would map to the entire voltage range, ignoring min and max settings, when sample and hold was active

  • Fixed an issue wherein presets could not be loaded when the sequencer was in a stopped state

  • Fixed an issue in which a release value of 0 would cause random voltages to appear at the CV output in some circumstances after the release stage had concluded in envelope modes

  • Fixed an issue with aux mode T16 not firing

  • Fixed an issue with quantization between 3-4 volts

  • Fixed an issue in which CV would not be applied in external clock mode

  • Added some first-pass improvements to the external clock and reset core: short triggers still preferred but further improvements in progress

  • Fixed an issue with humanize in which triggers could be dropped in certain circumstances.

  • Added an additional range to the humanize parameter (up to 200%, 100-200% now much more extreme in trigger offset)

  • Delay buffers now clear on stop to avoid previously recorded delay data playing on start

  • Shuffle now references the master clock instead of referencing individual step lengths and shuffle is now available per channel. Activate 'ALL' to change shuffle parameters for all channels or deactivate 'ALL' to set shuffle params individually per channel

  • Fixed an issue with reset sending triggers incorrectly.

Open Beta V1.03, UI Updates & Bug Fixes:

  • ALL now blinks and blinking is now synced to the downbeat.

  • New uSD param added - LOAD SYNC. When you press play, master clocks are running in the background to keep all channels tightly synced. This param allows you to schedule a preset to load, synced to the master clocks. For smoothest musical transitions, it is recommended to use a 16th value that matches the dominant sequence length of your rhythm. Options are 1-64 16ths (default = 16). Leaving the preset screen before the scheduled load activates, cancels the load.

  • Preset name now loads with the preset for easy overwriting/editing of previously saved presets.

  • The letter Z is now selectable for preset names.

  • Fixed an issue with CV inputs affecting all channels in some circumstances.

  • Temporarily disabled screen saver to investigate user reports of an audible artifact when waking up from sleep.

Open Beta V1.02, UI Update:

General UI Updates

  • The box that indicates the active step on the UI is now thicker and blinks to make it easier to see which step is currently being edited

  • Holding the * button while navigating the main UI now jumps between pages

  • Main UI pages now show the active channel and step at the top of the page

  • Changed the on screen text for coarse parameter change from 'X10' to '*' to match the interface button

  • The Green and Blue colours of channels 2 & 3 are now much brighter (if this is still not bright enough I will edit again in the next update)

  • Fixed an issue with step outlines disappearing while selecting a step to edit when long steps are active

  • The active page dots are now larger

​Preset UI Updates

  • All actions in the preset UI are now confirmed by clicking the right encoder button. 

  • The right encoder button now has 3 modes selectable at the top of the UI: SaveDelete & Load

  • Deleting a file is now instant and achieved by scrolling to it in Delete mode and right clicking (no need to enter the name)

  • Loading a file is now achieved by scrolling to it and right clicking in Load mode

  • Left click is no longer used 

  • The UI skips the Name params when in Delete or Load mode (much faster to navigate) 

  • Automatically overwrite preset added to Save mode (much quicker to save iterations)

  • UI text updated

  • The UI now remembers which parameter was last active when switching between the main UI and uSD screen making switching between the two to make edits, iterations, loads and saves much faster

Open Beta V1.01:

  • Fixed an issue when using clock dividers on more than 1 channel.
