Sure, I could use Roland's cloud service and get the same results, but honestly the JX is probably the funnest piece of equipment I've had when its niggles are not getting in the way.
Only thing is the Roland cloud VSTs, as good as they sound, are poorly optimized CPU nightmares. I had the cloud service for a while and at the time Roland was giving perpetual use of 2 instruments if you held the subscription for a year (which made it a decent deal). I kept the Juno 106 and the JV1080. The other day I decided to load up the JV1080 -- sounds great but the Cubase resource meter, which was not showing unreasonable averages, kept spiking, and it was the only instrument track loaded (the CPU is a 6 core i7-5930K, not a slouch). It wasn't affecting the sound (no popping), but if I see something like that during the initial creation of a track, I pull the plug-in because so much is going to be added later, things like Ozone on the master. I don't like to start out with low CPU headroom.
None of this would be an issue for me on the Jupiter-X, as it doesn't have the overhead of a PC operating system and can handily do multiple sounds. But, I only have room for one more full size KB and that slot is reserved for the P10.
I think you're doing the right thing, the Roland boards have a sound that works well in a mix. If I get a Roland synth, they are going to have to come out with a module with immediacy in the controls, and not the Jupiter Xm. But, that's a limitation of my physical studio space and my own priorities.
Right now I'm actually VERY pleased with what my new P12 module has brought into my studio, it brought the digital mojo I needed and then some. I was really tempted to pull the trigger on a Kodamo Essence FM MKII when I saw they are temporarily discounted to about $1300US... but I can get lots of good FM sounds out of the P12 with a programming model that works like my other subtractive synths, and the workflow benefit of that plus the analog filter is priceless to me. Over the last few days I've been sampling various sounds from the P12 into TAL Sampler (sampling plugin that allows you to emulate old chips like EMU II etc and dirty up the samples). So much fun!
