Hi all,

Yesterday I tried to activate and change the portamento time manually (I don't have the foggiest idea how to send the proper messages in MIDI from my M-Audio ProKeys).
Using the Group button I chose the Performance menu, then I used the Menu button to go down to Glide Time, and subsequently pressed Inc to increase the portamento.
Alas to no avail.

Did I misinterpret the manual?
Do I make some stupid mistake or omission?

Advice is highly appreciated.

Regards,

Ton
