[LAU] Ideas re MIDI controller to replace existing PSR keyboard?

Good afternoon! My present Yamaha PSR keyboard has sounds, but only 61 keys, no support for an expression pedal, and no aftertouch. I'm thinking about moving entirely to softsynths and replacing it with one of the following: Akai Hammer 88 Pro Arturia KeyLab 88 MKII USB MIDI Keyboard Native Instruments Komplete Kontrol S88 MK2 USB MIDI Controller SL88 Studio USB MIDI controller The keyboard would be sitting in my house, not likely to go on the road. I'm kind of leaning toward the Arturia but have no experience with any of them. Any ideas on how they work with Linux applications like Aeolus, Rosegarden, Yoshimi, etc? Thanks. -- David W.
