Change Log

Firmware 1.31 11 March 2024

  • Fixes

    • Fixed issue in v1.30 that prevented selection of the last scale mode (5ths)

Firmware 1.30 10 March 2024

  • New Features

    • Added ability to save and load patch

      • All voice settings

      • Sequence notes, scale, length, clock division and relative position of track 1 vs track 2

      • Excludes parameter-locks (unfortunately, ran out of RAM)

      • Save/load from temporary RAM

      • Save/load from permanent EEPROM

    • Added 3 new LFO routing modes

      • Octave (+- 3 octaves)

      • Carrier Waveform

      • Modulator Waveform

    • Added new Algorithm

      • “Call/Response”

      • Notes are only played every alternate loop, per track

    • Changed LFO routing UI to accommodate lots of modes

      • Pressing [LFO->] now displays the current LFO routing mode

      • Holding [LFO->] and turn [LFO DEPTH] to select different LFO modes for the current track

Firmware 1.20 24 June 2023

  • New Features

    • Added per-track clock division. Hold [FUNC] and adjust [SEQ LEN] to set the clock division for the current track between /1 to /64

    • Added ability to adjust brightness of the display. Hold [FUNC] on boot-up to access the master settings menu to adjust. When in master settings mode, press [REC] to save current settings.

    • Added new sync mode to disable internal clock. Allows for irregular input sync signals, eg shuffle time. Hold [FUNC] on boot-up to access the master settings menu to adjust the sync mode.

    • Added ability to save master settings. (display brightness & sync mode) When in master settings mode, press [REC] to save current settings.

    • Added Detune for each voice. Hold [VOICE] and turn [FM RATIO] to adjust current voice detune from -12 to +12 semitones.

    • Added new white noise waveform.

  • Fixes

    • Fixed a bug that caused the top right LED to not display correctly when adjusting rotary controls

    • Fixed the sync output in drone mode so that received sync pulses are passed through from Sync IN to Sync OUT

  • Enhancements

    • Routing LFO to various destinations is now adds to the base setting instead of replacing it. Previously the LFO replaced the setting value.

    • Amplitude envelopes are now exponential to allow for more natural sounds

    • Limited the drone mode frequency to 20-440 for a more usable range

Firmware 1.12 9 February 2023

  • Fixes

    • Fixed a bug that caused audible clicking every rest-step when the two voices were playing the same note but different octaves (!)

Firmware 1.11 25 January 2023

  • Fixes

    • Fixed a bug that sometimes caused sequence steps to be skipped if external sync input timing wasn’t perfectly in time

Firmware 1.10 21 January 2023

  • Fixes

    • Fixed modulation envelope not re-triggering correctly when still in attack phase

  • Enhancements

    • Defaulted to unison mode to make it simpler to get started

    • Made LFO destination the default function for [ALGO]/[LFO->] button. This will work on previous hardware versions but requires manually amending the text on the front panel (or just remembering!)

    • Increased octave range from 0 to 7

    • Drone mode: [AMP DECAY] now changes the master tune for the currently selected voice/s

    • Increased range of quantised-mode modulation frequency

    • Added visual indicator for sync input signal (top right of display)

    • Added visual indicator of analog control position

    • Modified record/clear icons to work with new analog control display

    • Added reset button combo in case it all gets too crazy! ([FUNC]-[REC]-[START])

Hardware revision 1.3 21 January 2023

  • Fixes

    • Moved reverse-voltage protection diode on DC power input to before electrolytic capacitor

  • Enhancements

    • Added thermal relief between ground pins and ground plane for easier assembly

    • Increased footprint spacing for resistors for easier assembly

    • Minor silkscreen improvements for easier assembly

    • Spaced controls further away from audio/sync jacks

    • Added greater tolerance for potentiometer shafts in faceplate

    • Reversed button label for [ALGO]/[LFO->] on front panel: now LFO destination is default, ALGO requires holding FUNC button
