Absolutely lovely groovebox, the workflow is very fun and deep, virtually endless possibilities.
The sound is really unique and wide, but the being a specific FM synth is not suited for everything of course.
What didn't convince me was the build actually. The unit itself is sturdy and well assembled, buttons are ok, pads are not the best and is a well known problem, but the really disappointing thing is the knobs quality.
I got two different units and they both have inconsistent knobs, some of them are stiff, some are very loose, all is very random. Quality control doesn't seem to be the best or they use cheap encoders, I'm not sure. The first unit I ordered had the Color knob with a sort of internal click, like the middle dent of a pan knob, really annoying.
I returned both the unit back at the end, but it was just me, I didn't like the knob problem, even if they were working properly. Also I'm more oriented to the Model:Sample, which can be more versatile. Or better an Sp-404, let's see.
Anyway, if making electronic music of any kind is your goal, this machine can do it wonderfully. Ambient, IDM, dance, techno, the only limits are imagination and skills. Price is fair, tons of options and most of all is very very fun, probably one of the funniest machines out there.
