32 poly,at least,is a step up from the 24 poly of earlier WK's(my 1350 is 24 poly)but another area where Casio could improve is the number of on-board sequencing tracks.2 extra for a total of 8,for starters-maybe even 10 or 12.The polyphony would naturally have to increase to 64 and I think that would do it for awhile.

Another complaint:The linear sequencing *sucks* and there is no reason to believe it has changed for the 3700,and that is sad.
Casio has assumed that the majority of their users were sophisticated enough for the onboard sequencer,200 DSP and a 16 track mixer.They should take the next step and install a pattern-based sequencer which would allow you to work on little bits of your songs/instrumentals,at a time,then string them together in a song mode.This would eliminate having to start the WHOLE track over due to mistakes made.It would all but eliminate step-editing(step record would probably remain though as a viable option)
