Among the very accessible things include a very clear signal flow with decent metering. I use it as a stereo mixer with lots of mono ins, an output module and six track recorder. This is just the top level stuff.
Currently I’m just quick saving to memory slot 1 each nightly power down, pop back in next evening and load up my quicksave. This makes keeping the patch evolving between days real easy. Often I just use it for easy tasks like those. A little limiter, an EQ.
Navigation reminds me of when I used to have an MPC2000xl, where the big wheel conditioned my muscle memory.
An added level of complexity is processing samples and signal chains with external cv control. The looper and granular sample handling is slightly more complex but should still be fun.
Suddenly there’s a downloadable custom unit which adds all sorts of fun with macros.
It’s just in light use but also just what I needed to keep the lid on the GAS.
