Hi Rikki,
Nothing really, it's just that some areas of the operating system and hardware have not changed since PA1x days..You still cannot place or use markers in a midi file, you cannot enter scroll points in a midi when using the text option, the text option is very basic with no ability to have spaces in a line of text (ie when you have chord symbols above a line of lyric) insert effects can still not be used with a sound selected via midi (without a convoluted workaround!!), and a couple of others.
These are things I have discussed at length with Paolo over the past few years, and made suggestion after suggestion to no avail.
Sonically, its superb, style-wise it's superb, great pre on the mic input.
Simply put it's just not for me from an operational pov.
It's still a super keyboard though!!!
For the moment I am back to the SD1+, but the dealer is maybe going to work a bit of a back-trade for the Midjay, but I won't decide until I see the numbers.
Cheers
Dennis
