I have a Casio CTK-680 which I am trying to connect to my PC using Cakewalk
It is a MIDI but not GM Midi

So far I can only get the sound-card on the
PC to play using the Casio keyboard- using
Single and 4 Channels

How do I get the PC to play the Casio?
Can the accompaniment and rythms be recorded
into the Cakewalk?

My PC is connected from the plug and play port via cable to the IN and OUT midi port on the Casio
I have tried the MPU-401 as output but still no go
