User instruments

[Wasted]

Hi all, I've just run into this, and not sure if it's user error or a limitation.
Is it possible to load two instruments from two different user banks?
I can load one instrument from a user bank fine, as long as the other instrument is factory.
I can also load two instruments as long as they are both from the factory bank.
Thanks in advance, Kev
OK, so I just tried to start from an init patch and now it is working as expected! So definitely a case of user error, or a strange state the PX was in when I first tried to add user instruments to an existing preset.
