You might need to run the updater as sudo depending on serial port permissions
Mac
The firmware updater will ask for permissions to access files on a removable volume, you should accept or the update will fail
During the update, there’s going to be an eject warning that you can safely ignore
Updating might fail intermittently because of a Mac OS driver issue, trying again should help
Windows
After you connect the Redshift 6 to a Windows computer with USB for the first time, you might need to reboot before the firmware updater works
Version 1.4 (Released 2025-10-01)
New Features
MPE
Settings page now has options for MPE
Assign MPE Timbre (CC74) modulation by holding the MIDI button
BREAKING: CC for Cutoff is now 79 (to avoid clash with MPE Timbre)
New oscillator waveform variants that reset on incoming note
Arpeggiator
Envelopes now have a Reset parameter
Defaults to Off for analog-style envelopes as before
LFOs now have a Sample & Hold waveform
Multi-part editing
Quick edit
Hold down one or more part buttons while turning a knob to adjust the parameter for all held parts
All parameters will be set to the same value, i.e. the editing is absolute, not relative
Latched edit
Hold down a part button while selecting/deselecting others by tapping them
Adjust parameters to edit all held & selected parts
Let go of all held part buttons to exit multi-edit mode
Tip: this is a great way to assign multiple parts to the same group
Load individual parts from presets
There’s a new control “Parts” on the Preset page
By default it’s set to “All” which works as before
Other options will load individual parts from the preset into the selected part
For example, “3 -> 4” means “load part 3 from the preset into part 4”
You change the first number (“source part”) by turning the top left knob
You change the second number (“target part”) by choosing a part with the 1-6 buttons
The result of this will be previewed as usual; press Ok to confirm
If you want to load multiple individual parts, you need to press Ok after each one and re-enter the Preset page
Enter single part load mode by holding a part button and tapping Presets
Parts option defaults to loading part 1 instead of all parts
Selected part doesn’t reset to 1 while scrolling presets
Improvements
New factory presets showcasing MPE, the arpeggiator and more
Stepped pot response is slightly less overenthusiastic now
Add grace period after releasing a parameter knob or Shift to prevent accidental edits
Preset scrolling is a lot more responsive now
There’s now a small delay before loading presets while scrolling
Filter Mode parameter now snaps to BP in addition to LP & HP
LFO range is now 0.01-1000Hz, up from 0.1-100Hz
Note that might slightly change the sound of presets using audio rate LFOs
BREAKING: Cutoff CC now controls the full cutoff range
When holding ENV + LFO, ENV now becomes the via
Minor visual tweaks and fixes
Fixes
Correctly follow external clock when looping
LFO synced to a source would not sync others correctly
For example LFO1 synced to LFO2 synced to clock wouldn’t work correctly
Tap tempo works without Shift pressed again
Illuminate Parts button when Shift is held
Occasional crash when loading presets with reserved voices
Env amount bar on VCF page is now bipolar
Buttons sometimes got stuck when loading or initializing preset
Stepped adjust now works again when assigning modulation
Version 1.3.1 (Released 2025-06-26)
Fixed
Fix buttons sometimes getting stuck in very specific circumstances
Version 1.3 (Released 2025-06-16)
Added
Multitimbrality
Multitimbral factory presets
Preset preview: presets are automatically loaded while browsing
Amp & VCF envelope ADSR controls now have CC numbers (see manual)
Key page now has controls for Low/High key limits
Changed
Polyphony & Unison on Parts page now limit each other
Parts page now shows how Paraphony is limited by Stack
Trigger parameter is now on the Perform page
Mod Matrix now scrolls to latest modulation assigned with quick assign controls
Note tails are now cut when changing presets
Change Character NRPN number because Reaper for example is sending 0, 0 to reset CC/NRPN (see manual)
Disable Shift Lock when loading preset
Parameter overlay logic tweaks
Improve stepped knob response
Visual tweaks
Fixed
Changing parameters with MIDI now makes preset show as modified
Fix perfectly overlapping notes not retriggering
Overlapping notes now work as expected
Fix crash when modulating Character in the negative direction (and potentially other weird behaviour in modulations)
NRPN compatibility fixes
Fix buffer overflow when sending a lot of CC messages to the synth
Clock setting was shown based on external clock on clock page, even when internal was selected
Modulations were being applied to the last parameter modulated when turning a knob with no assigned parameter (such as when turning the top row of knobs on envelope pages)
Version 1.2.2 (Released 2025-06-02)
Fixed
Firmware update improvements
Version 1.2.1 (Released 2025-04-08)
Fixed
Fix occasional crash when sending CC/NRPN messages to the synth
Firmware updater is now more robust especially on Mac
Version 1.2 (Released 2025-03-31)
Added
Clock that can be synced via MIDI
LFO clock sync
Tap tempo
All parameters can now be controlled with NRPN and some with CC
Velocity to Amp quick modulation on AMP page
Mod lock
Double-tap a mod source to latch mod assignment mode
Hold a source and double-tap another one to latch mod + via assignment
Tap the blinking source or via button or Esc to unlatch
DCO keyfollow setting -400% to 400% on the KEY page
Keyboard octave switching: Up/Down on Key page, or Shift + Up/Down anywhere
Filter keyfollow snap to nominal 1:1, 2:1, 3:1 (these are not super accurate in self oscillation)
65 new presets by Gattobus, Starsky Carr and our team
Changed
New parameter adjustment logic
Default is as previously, except adjustment is more responsive (much smaller “deadzone” when starting to move a knob)
Holding shift now enables parameter fine tuning, allowing for much smaller adjustments (you can for example adjust tune by less than a cent)
Double-tap Shift to latch fine tune mode, tap Shift or Esc to unlatch
Parameter steps are now accessed by holding down a knob while turning
Perform page now shows clock status and incoming MIDI
Clarify a bunch of names around the UI
LFO Reset Phase now has steps at 25%, 50% and 75%
DCO Stack & Detune visualization now more accurately reflects what’s happening in the voice
Short grace period after adjusting modulation to prevent accidentally changing the parameter
Keyfollow now also follows pitch bend and portamento (might change behaviour of some presets)
Minor visual tweaks and fixes
Fixed
LFO now sends reset signal also when it is externally reset itself
Note that this may change presets where you have multiple LFO’s synced in sequence
Reload preset now works correctly
Multiple panel controls can now be adjusted simultaneously
Bottom of Settings page no longer disappers after a parameter overlay is shown
June Harp preset had Pitch -2 by accident
Voice no longer crashes at very low pitches (only accessible by piling several pitch modulators in the negative direction)
New pitch limit is 0.256Hz for the pulse oscillator, 0.128Hz for saw
Voice processor was skipping frames, causing clock and LFO’s to lag in certain presets
Fix crash at boot if synth had exactly 256 user presets
Fix reversed visualizations of LFO Log vs. RevLog waveforms
Dual Osc Noise level is now affected by DCO env in para mode, and by gain scaling related to character and drive, as it should be. This may affect the noise level in some presets.
MIDI notes now stop when:
All Notes Off CC123 is received
MIDI channel setting is changed
MIDI Panic is pressed from front panel
Repeatedly pressing MIDI Panic no longer crashes the synth
On fast envelope decays, the envelope no longer gets stuck to its previous sustain value, when sustain level is changed or modulated
