Concept and power/capabilities go hand in hand. It’s really only a learning curve, and once it is overcome, its advantages become clear.
When compared to many other multi-timbral synths, the Kit system is quite elegant.
It makes copies of sounds that exist on the +Drive so that you can edit and abuse them beyond recognition and never lose the integrity of the original sound. The original patches sit safely on the +Drive while your machine’s RAM holds the Kit.
This one feature is the biggest limitation of the Blofeld, and because of Blofeld’s omission of this feature in its own Multimode, great care has to be taken to stay organized so that you aren’t editing patches in the patch memory that are used in other Multis.
This attention to organization takes away from music making.
Synths like the Virus and Nord Lead have non-destructible multi-timbral “kit”-esque systems as well. Even the DSI synths do. But the difference with Elektron is you have a highly effective sequencer that can access those kits and do advanced things like trig mutes, parameter locks, parameter slides, probability, fills, etc.
Powerful multi-timbral organization at the machine level + powerful sequencer will never equal simplicity. The learning curve is the price to be paid for vast capabilities in a single sequencer+synth package.
