Freeze (Red screen) was possible when editing Synth engines

Version 1.1.0 — 11 Nov 2024

NEW FEATURES

Version 1.0.1 — 18 Dec 2023
1.0.1 finalizes the synth patch editor and includes several bug fixes.
NEW FEATURES
Finalization of synth patch editor
Adds Saving and loading synth patches within projects
Clarification of controls and labels for parameters
Knob name is displayed on the synth macro editor page for easier navigation and editing of macros.
“Init Patch Loaded” is displayed after the Init patch action in the synth menu.
FIXES
The LFO Ratio synth parameter value was occasionally loaded with incorrect values within the patch (*)
Changing the synth Model and loading the first Patch in the list left the previous Patch name displayed
WTFM synth Glide Time value was much shorter than the displayed value (*)
Synth Glide Mode values became out of sync with the display when scrolling backward through the list of modes.
WTFM synth had “Env 1” listed twice under Macro parameters (Env 2 is missing)
Using the Back button when naming a synth Macro temporarily saved the name change, but not after exiting and re-entering the Macro page
Confirming the synth macro name too quickly left glitches or the wrong name in the UI header
The latest synth macro changes were not saved and recalled when restarting the unit
Synth Patches with Voice Volume mapped to another Macro (instead of Velocity) could load with incorrect volume parameters (silent)
Synth Macro names longer than 20 characters didn’t display correctly on the screen UI
Macro names are now limited to 20 characters
The bipolar macro value didn’t get saved after using the Tempo knob to change it
Occasionally the wrong Patch name was displayed after loading a project
BREAKING CHANGES
Fixes marked with (*) might make previous projects and synth patches sound different if they use Glide (WTFM synth model only) or LFO modulation (all synth models).
KNOWN ISSUES
Occasional crashes when tapping the Randomize knob while switching pad presets in Perform mode when Knob Double Tap is set to “On” in config Settings
