Sorry, the word wasn't really appropriate because , yes, it is standalone... What I meant is that the Spark can't be used away from the computer.
As a software based drum machine, one of his main advantage relies on the fact it will evolve with software evolution while as a controller it depends on its integration and compatibility with all his digital environment (computer, OS, DAW, VST...) and it will needs constant software / pluggins / codecs upgrades to adapt the evolution of those technologies... So far, Arturia has offered very good upgrades and still does with the promising 2.0 spark software version, but one can wonder if they will carry on for a discontinued hardware...
That's also why I was dreaming about a possible new Spark hardware, which would be a real "hybrid" equipment combining an analog standalone drum machine and a midi controler for VSTs, with lots of controls (pots, pads, switches, sliders !)
... Something that could compete with all the NI Maschine MK2, Elektron Analog Rytm or Dave Smith Tempest... and which will hopefully blow away the Aira TR8 !
That would make sens to me that Arturia develop such a top end hybrid drum machine / controller to complete its range with the Beatstep and the SparkLE. Well, that's just me dreaming
