I canīt contribute much to this forum, still I pop by to read some of your comments as Iīm allways torn between a workstation and an arranger. I listened to the tyros, 9000, the ketron sd-1, fantom and motif. Ease of use left aside (workstations can learn lot from any arranger!) I never found an arranger with convincing drums - soundwise and stylewise, that is. The Fantom was the first keyboard with ease of use, very good punchy drums, smooth overall sound, but:
A very annoying storage medium (floppy!) thatīs incredibly noisy. And no way to open up the fantom for more than the existing user patches except via floppy. This is its biggest drawback if you do not rely on sampling. having to load everything via floppy is something I did not expect from such an expensive keyboard. Even cheap gear sports memory cards of all sorts and much more user memory, roland in that regard is still in the stone age (sorry, my english)...
