I need help from the electronic music hive mind!

What are the electronic instruments you've played over the years that are DEAD SIMPLE to use? Meaning, a person with no experience could walk up to it and quickly and intuitively move some knobs around, poke around a bit, and start exploring the instrument?

Samplers, synths, drum machines, and recording tech suggestions are all welcome. Boost if your followers would know about this pleeease! <3
