It works similar to the JX3P.... you select a parameter... say DCO-1... All the parameters are as red LED 2 digit displays... then you assign a 2 character value to that parameter like say filter cuttoff = maybe 42... so 42 appears and you set it's level to 0-99 setting... simple....

Anyways... you can I belive stack oscillators to get a layered sound.... The DW6000 is 6 note poly with 2 oscillators per voice... it's a DCO synth, but the rest is analog.... 8 different waveforms, plus Noise... and good res filters... no velocity tho..... but a great little, often looked-over real analog unit at a snip price.....These can go real cheap if you are lucky.... most people think they are junk cos it dont say 'Roland' on the front and have alot of knobs !! ......If you're looking for a nice digital synth... forget this , it's pants for that... and thus it's not rated at all... but for dance waves , with very good filters... & midi... take a look !

The DW6000 ... Comments please....
