So I got the update (which I love! Well, minus the bugs of course..) of Spark to spark 2  and I have encountered some bugs:
When in STUDIO mode, klicking  on a sampler unit to load a new file from within windows, on the new window it says the following:
  "Please select the moose you want to load..."
Whatīs a "moose"??

When in LIBRARY mode browsing sounds from DISK, the preview volume don't work!!;( This is super annoying because the sounds on my disk
 are usually at a way higher volume level and I have to turned the main volume down for my system everytime I choose sounds and after that        turn  the  volume  up again. I tend to jump back and forth making a beat so it really drags down the workflow.;o
I canīt change the volume of the metronome. Even if I turn the volume down to zero  on my Spark (Every channel) the metronom is still at its default volume!
Spark 2 crashes when  exiting the program, way more often then the previous Spark, would a dedicated "EXIT" in  the menus help this? 
Finally, a suggestion, please make a function so you can copy single instrument tracks 
from one pattern to another!! 
If you have like 6 patterns already and record a new instrument without quantisation and with
complex automation in pattern 1, either you  delete the other patterns or rerecord the part
for every  other pattern, that's just silly to have to do when having a powerhouse like the Spark infront of you.;(
It's super easy to copy single tracks/instruments on my Ensoniq EPS 16+ and
that unit is a bit older than Spark 2 to say the least!
The bugs I mentioned is present when running Spark 2  both stand-alone and in DAW,
I run Win 8.1 (Latest updates), Intel i7-4770K CPU @ 3.50 GHZ, 16 GB RAM,
Soundcard: M-AUDIO FAST TRACK C600 updated for win 8
DAW: Studio One 2 Pro latest update
My Spark is the original controller
Besides this I would like to thank you for this machine, I really love the whole Spark concept, a real dreammachine!:D
That's why things like the can't copy single tracks are so dissapointing. Hope you will change this.
Peace!
