In Kontakt 7, I have selected in the options to send MIDI generated from script generated notes. When I do this with Playbox, it works as expected with the exception of it also playing a C2 note that is sustained as long as you press any key. It doesn't matter which key you press, it always outputs the C2 note along with the Playbox MIDI notes being generated by the Playbox arpeggiator.
I tried this in Studio One 6 and also Bitwig, so I don't think it's an issue with the DAW. It also happens if I just play the onscreen Kontakt keyboard, so I'm thinking it might be a bug with Playbox, unless I'm overlooking something simple.
Has anyone else had this issue or know how to fix it?
