The Juno DS88 has Hammer Action Weighted Keys and the DS76 and DS61 both have Synth/Organ Action Keys.
I know this for a fact since I traded up from a 61 to an 88 in the first year I owned one.
For Progressive Rock style music that the fellow mentioned he wanted to produce the Juno is an EXTREMELY CAPABLE keyboard.
Over 1400 factory sounds and drumkits loaded at the factory and free expansion kits available from Roland via download. Very easy to use sampling and a vocoder and pattern sequencer as well.
They put out an excellent set of tutorials when they introduced the board and the OS has a lot of sophisticated features. My only disappointment so far with the board is that when recording MIDI from the
STEP SEQUENCER*** into a DAW it does NOT Xmit MIDI Signals (nor USB) to the computer.
(correction*** step sequencer does not transmit midi. NOT the entire board. All other MIDI functions are nominal.)
There are workarounds else I would have sold it a year ago.
The Ivory Feel keyboard was weird for the first month or so but you adapt pretty quickly.
The 61 key model DOES NOT have Ivory Feel.
As my backup workstation it really has everything I need to do some composing with and overall I still say that even now it's still one of the best values per dollar on today's market.
For a SERIOUS, introductory keyboard, the OP could do a lot worse than one of these. If he finds a gently loved preowned unit for 30% off Retail plus taxes he would have an excellent startup for his future studio.
If he's planning to gig with it then he'd best pick up a solid, padded gig bag, because it weighs in at 34 lb.
I believe the Kross 2 88 weighs in considerably lighter (hence the less than great action) and if that is a major consideration to him then he would be as well off with that one.
Both keyboards have their merits and drawbacks, price positioned so as not to compete with their upscale workstations.
I have a decent bag for my Juno but I don't go out gigging with it either.
My advice to help make the OP's choice is to screen a few of the Youtube Tutorials for both and download and browse the manuals for both before he pulls the trigger.
