Hi, I've just finished building my Sammich and I love it. The only problem I've found is that I can't save NRPN changes I've made to a patch while using a BCR-2000 to alter the sound parameters. From the documentation, it implies I need to enable 'Edit Mode' by pressing 'SHIFT + DOWN'. But it looks like the down cursor arrow on the Sammich is a 'Page Down' rather than the equivalent of DOWN on a MidiBox Sid, which means 'Edit Mode' is inaccessible. There doesn't seem to be a CC/NRPN/SysEx command to enable it either. Am I missing something, or is there a way around this problem? Thanks, Graham
