You can plug the Denon’s and use them in HID mode, way better resolution than MIDI. It won’t be easier (since both ways are pretty simple) only cheaper.
Im a little interested in this post, cause I would like to add two CDDJ to my S4!! My question is what is a good CDDJ to use that doesnt just kill the bank account? Im not a scratch DJ, and only use the jogs to scan tracks and ajust cue points. Im just thinking about some to control C & D functions like like play, que’s, ect.
IMO get anything by pioneer…not that I’m a fanboy but it is pretty standard for clubs to have pio decks and mixer…so if u ever do club gigs u are familiar with them
800mkII’s have a great feel to the jogwheels, if you want to be able to have button control you may want the cdj400s. Have you looked into the denon dn-sc200’s? They are cheap and can give you the extra jogs.
