This query is a carry on from here, http://www.cubase.net/phpbb2/viewtopic.php?p=960845&sid=dc23bebda8db79f8861f23a095751776
I too have a JD-990 for which I’ve tried to create a device panel - what a nightmare! The whole process is clunky, as described by others in the above thread. I sure wish SB would take another hard look at this feature and make the improvements it needs to be a useable feature.
Steinberg touts hardware integration almost everytime they have something to say about Cubase, but the simple fact that there are very few Device Panels available for hardware gear speaks volumes, let alone all the complaints/disappointments from users like me who’ve actually tried to create a panel for their H/W device-synth.
