Tetrachords

Firmware & Resources
Latest Firmware Release Notes
  • Added CONFIG.TXT option RESPOND_TO_MIDI_CC. When set to ON, the Tetrachords responds to MIDI CCs received on the MIDI channels assigned to each track. When set to OFF (or not set), the Tetrachords didn't respond to incoming MIDI CC messages.
  • Added CONFIG.TXT option SHIFT_BUTTON_ACTIONS:OFF. This disables SHIFT button actions such as SONG + SHIFT deletes SONG; PATTERN + DELETE deletes pattern et cetera. With SHIFT_BUTTON_ACTIONS set to OFF, the SHIFT button functions as a modifier only.
  • Added CONFIG.TXT option CV_VELOCITY_MODE with options CV_VELOCITY_CONTINUOUS and CV_VELOCITY_GATE. CV_VELOCITY_GATE is the default. When the TRIG IN signal goes high, the CV OUT outputs a level corresponding to the current note's velocity. When the TRIG IN signal goes low, the CV OUT outputs 0v. With the setting CV_VELOCITY_CONTINUOUS the CV OUT adopts a level corresponding to the current note’s velocity and holds that level until the next note is triggered by the corresponding tracks TRIG IN.
  • Fixed bug - UNMOD would UNMOD non-linkable parameters on all linked tracks.
  • Fixed bug - Switching TRACKS no longer bumps the Tetrachords out of UNMOD mode.
  • Fixed bug - Switching TRACKS no longer bumps the Tetrachords out of LATCH mode.
  • Updated note-on/note-off handling for Polyphonic MIDI to CV.
  • Fixed bug - MIDI Inputs received on Channels 9 to 16 didn't register correctly.
  • Fixed bug - LEFT button didn't navigate MIDI IN pages whilst SHIFT was held.
  • Fixed bug - Tracks 2,3 & 4 would exit keyboard mode when a pattern change was triggered by CV.
  • Fixed bug - UNMOD didn't work for cascading inversions.
  • Fixed bug - RGB button LEDS remained illuminated when changing to other UI modes e.g. when pressing SHIFT + CV to configure CV outputs.
  • Fixed bug - Pressing the LINK button whilst in keyboard mode would exit keyboard mode, causing any playing notes to hang.
  • UI fix - LED pills are now blank in UNMOD mode.
  • Fixed bug - Independent tracks sourced their root note from the selected track scale rather than their own, resulting in non-independent behaviour.
  • Fixed bug - MIDI notes received via USB could cause SD saving to crash.
  • Fixed bug - Notes 5-8 wouldn’t always play with 5-b5-4 set to 4.
  • Fixed bug - Trig Mods didn’t advance settings as expected after the modulated parameter was manually changed.
  • Fixed bug - Trig Mods would modulate linked mods on the selected track rather than the track assigned to be modulated.
  • Fixed bug - Trig Mods on CV IN 1 to 4 didn’t work on tracks 2,3 or 4.
  • Fixed bug - STEP SEQ LED didn't always show the correct state when changing patterns.
  • Fixed bug - Deactivating the current playing pattern would leave the module UI in a weird state, leading to accidental pattern copying, deletion, and general bugginess.
