I could need some advice on what to buy. The Roland seems robust and easy to use, but maybe a bit boring? From what I´ve heard the EX5 has got some midi problems and a lot of the sounds you can only use in performance mode. Is the EX5 just good as a sound sorce for sampling, or does it work well with a sequencer? I´m mostly interested in making electronica and don´t really need orchestral sounds and similar.
