Fran-
any idea if the BK-5 will drive a Ketron SD2 or SD4 - I see it does not have a sequencer for rhythms/drums including drums?
Sparky, yes it will send and receive midi data...thus control the Ketron units...both SMF play and arranger play will transmit the data to the SD models..
The lack of a on board sequencer prevets the recording of the midi data originating from the keyboard, but not the transmitting of the same data...
