I just added Spark to my collection, Ive been watching it since it came out but waited to see how the software developed. Now it has the features and kit choices I think warrants its price.
Ive already got NI's maschine, an elektron machinedrum, and an R8 for drum duties, so Spark fills a few gaps in there..
So far the highlights are the controller, which other than some apparently flimsy legs feels solid and is well laid out and featured, the cons are the softwares a little buggy, Ill have to do a bit of troubleshooting, and Im not keen on the older Roland kits, my R8s expansions take care of these...the newer kits sound great and are on par with NI, plus you have so many patterns built in to play around with
Im a sucker for step sequencers, and the ease of dropping in you own samples is great for the workflow...plus a decent mixer and great layering options makes me think this is going to be my go to for a while
anyway, long winded intro...keep up the good work, I look forward to updates..Id only ask for stability over features..
