All the Spark template does is change the MIDI notes on the pads to match Sparks.
It doesn't let Beatstep control the transport in Spark, it assigns no encoders in to Spark, not even the arrow keys for the pattern in Spark are assigned to Beatsteps absolutely similar arrows.
In my opinion this was a huge failure in terms of Spark and Beatstep. Arthuria designs both, and even designed them to have similar features, that don't integrate.
I think it's a missed opportunity. I own Beatstep Pro and Spark, plus Maschine Studio, Ableton Push etc. I have a plenty of drum controllers including one from Arturia, so it would be very very hard if not impossible for me to justify buying Arturias hardware controller that looks exactly like Beatstep to do what in my opinion Beatstep should be able to do.
I'm actually very shocked that Beatstep Pro works and integrates with dumb drum machines like Battery and Lives Drum Racks. With Arturias own drum machine, it's awkward.
