Hi Jason
I was also speak with Dave. He gave me consultation about aftertouch etc. and it works. But he also told me that there is a possibility of programming Glide and that there is a way how to transmit this Glide messages to Vienna. But that's all I know and I didn't succesed in programming that.
If you will speak with Dave, try to ask him about this. Maybe he coul make for us a manual how to programm Glide to make on string etc.
Have a nice weekend and if I will have some new informations I will write it here.
