Diki,
With all due respect ( and gratitude for having helped me during my brief fling with Roland arrangers earlier on this year) yours is a very long story but to cut to the chase:
Roland should simply have retained a touchscreen. Contemporary keyboards have that many parameters that can be changed that is it virtually undoable not to include one. And even with one included ( like on the G70) I still found the Korg OS much more accessible. I know you and Fran will disagree but like Deane says it is not a contest. And Deane is making a point there as many times you and Fran have stated that you often bypass the arranger or part of the arranger using simply RH voices, manaul bass and drums.
All in all it was an interesting odyssey that Deane was on. I wish him well and advised him to try and intergrate the PSR950 with the Micro Arranger, both of which he is pleased with.
regards,
John
