Mine arrived today (JX and JU, no JP in UK yet - unless you are in a boyband ) having had extensive experience of the originals, at the price these cost there is little to complain about, the sound is close enough for me - and I can be a bit fussy. Certainly the bass is powerful and the handlng is not as bad as you'd think.
I could live without the ribbons and the sequencer (seems a bit clunky to use so far) the poly is not a deal breaker for me, I'm not into power chords or Jump covers For techno chords which is IMHO what the Juno and JX are most famous for then they fit the bill perfectly, I like that they are small and can run from batteries, the build quality seems more solid than I expected.
The extra features added to the JX are very nice (more waveforms, more mod options for DCOs) and I think I prefer it to the JU - just, which is the opposite how I feel with the full size vintage versions.
Yeah, they are not going to break new ground, they are however a great way to add those classic sounds easily and cheaply to your setup, my MC-202 and TB-303 and TR-606 do mot have CC implementation either, and I still manage to use them fine Of course that is not to say a CC update would be useless, but for me not a huge problem as they are fun to tweak by hand anyway.
Very impressed, and I will deffo get the JP as well.
