i just received yesterdeay an sp-404. i've got also an sp-303 (and in hte next days i will receive an sp-606! you know, i'm crazy
i'm trying to compare the two little beasts.
the sp-404 is more practic to interface with other gear(i talk about import/export .wav/.aiff and other stuff).
i found that the sp-404 pads are a little bit harder than the sp-303 pads. i also notice that the 2 machines sound a little different (the sp-303 is more rough), and sp-303 compression fx is more convincing (to me) than the same sp-404 fx.
unfortunately a also noticed that quantizing in recording patterns is more "precise" in the sp-303 than in the sp-404; i found it more difficult in the sp-404 when i put quantize on 16 and more....i hoped that the fact that sp-404 got a 32 quantize would helped me to have more rythmic variations, but until now it doesn't.
...maybe it's only a question of consuetude (just 2 sp-404 days) , but...
