I always had a crush on Roland products. I picked up my first keyboard last October by Native Instruments, the S series 61. I hate to say I just didn't like it and went with my first intuition and picked up the JUNO DS61.
This keyboard, for the price is actually very sophisticated. You can download additional patch banks from their Axial site, edit the internal patches and even layer them from the keyboards display or the included software!
I've been using more and more of the internal patches in track, they sound very good to me. But keep in mind, mI am no pro and am inexperienced.
People complain about different companies including Roland saying stuff like "Their sounds are outdated".
I don't believe a sound set can be outdated and if it sounds good in a song than that's all that counts.
I later added an Akai Advance 49 to my collection. But hopefully returning it soon. Shame really... I love the VIP 3.1 Package and the form factor of the keyboard itself. BUT, I like synth action keys and the adjusting of parameters in the Akai is pretty limited.
My vote goes for a Roland Juno DS61.
P.S. I hope to get an Roland Integra 7 someday!
