So, after checking this Driver today, I can say, yes this is the correct Version. It is VC3 Only, because it uses a lot of ACK Commands to get Timecodes, Names, States etc.
You can get the Timecode of the Main and an AUX Timeline, Jump to Cue Named X on Main and AUX, set Midi Values (2 Commands, one for single and one for a List of Midi Values), is watchout running/standby, Cluster OK etc. So you would be able to react on the State of the Programmer software if you want.
If i have time, I will Update this Driver to VC4. This will be my first Project/Driver in VC4, if Dierk hasn’t already update this Driver… 😉
