I agree with all of the above - Mopho is far superior build etc but I’d go BS2 for one reason - immediacy, fun, real time tweaking.
(Edit: okay that’s three reasons
)
You say your not a keyboard player, neither am I, so that extra octave on the mopho is kinda moot, and what do non keyboard players love? Sequencers and Arps! The BS2 sequencer/arp is an instant gratification module - it’s super old school SH101 style, dial in some notes and play - store sequences, mess with timing, switch between em in real time etc. I tried a BS2 in a store and fell in love just on the strength of that. I know the mopho has a seq too, and it’s cool but maybe a bit too old school
I mean it’s modelled on a 4 x 4 grid matrix thingy like old analog units right ? - is it smooth to work with live? Easy to dive in and tweak real time with one hand?
Of course BS2 sounds great too, has some nice presets which I’m sure the mopho also has - but now we get into the realms of subjectivity - they both sound great right? They both have the heritage, the vintage whatever you wanna call it - both can easily do the BOCy vibes.
Tough choice - try do a side by side comparison - for me, BS2 workflow is The Boss, and probably a better choice on stage for a non keys player - less complicated but just as complex (if that makes sense
).
