Gee, you love a Yamaha instrument? Go figure hey??!!
Stephen Kay was looking to include Karma Software for the the MOX series as well as the XF/XS..there is certainly nothing much more that can be done with the hardware architecture..
Ian, I have owned the XS, XF S70XS...and tried the MOX in the shop...there is not much you can tell me I already don't know...and there certainly is no plug in arranger module coming...
Unless you can somehow configure Karma as a pseudo arranger but as Stephen Kay has repeatedly stated, Karma is nothing like an arranger.
However I believe he has modified Karma 3 (NOT available for the Kronos btw) to be able to use pseudo fills and ending Combis - but I do know that with Karma a computer is a 100% necessity, otherwise it won't run...got that from Stephen himself...
So no intrigue for me here...just a cursory (VERY) curiosity
Karma is very much like an arranger if you want it to do so... ,... even a Fill on KARMA 3 (tough it plays on top of the other channels instead in place of them). You just don't have fills/intro's and endings. But KARMA is so much more.
And then a Motif can do just the same when using all 5 arpeggios to follow your chords.... As a Motif can do the same as the MOX and more. (KARMA will obvioulsy not come to the MOX)
I have a S90ES which is comparable to an Motif ES and with its plugin boards it blows away the MOX in sound quallity and options. On top of that it has one of the best 88 keys keybeds ever avaialble and was cheaper then the MOX in new condition.
But in the end, Mox/Motif/Kronos can function a tiny bit like an arranger, but they could never replace it for someone seriously attached to their intros and endings... someone that wahts to replay the orriginal music as best as possible.
