I'm currently trying out the demo and considering purchasing the SparkLE when it comes out, but I noticed one thing that's missing and which would really help the workflow. I use Spark as a VST and when sequencing a track and I like to do all my sequencing in my DAW. Currently you can drag'n'drop only the whole pattern (or use "Send MIDI From Sequencer to Host" and record it), but then you have to edit it to separate the sounds. It would be very useful, at least for me, to be able to drag'n'drop just one pad (or alternatively, when sending MIDI to host, to not send MIDI from muted pads).
