We have been made aware of some reports that Virtual Instruments in Pro Tools are receiving spurious/random MIDI data from SSL V-MIDI ports configured for HUI control (required for UF8/UF1 DAW control and UC1(Transport control). This is causing the triggering of 'ghost notes' being played.
We have raised this issue with Avid.
The issue seems to have been introduced in Pro Tools 2024.06.
To workaround, please set the Input to your Virtual Instrument Track to something other than 'All' e.g. choose the specific input from your MIDI controller keyboard.
