Keyboard Sacn Matrix, C-Code

[henrygr]

OK guys. Am about to try to upgrade an old keyboard (Roland JW 50). It is c. 1992, and i think it is the same keyboard that would have been used in the JV series. I say this, as there are plenty out there, and if I can get this nailed down, then it might open up the door for others to follow suit.

Saw this thread http://www.midibox.org/forum/index.php?topic=6386.15

Thing is, a year into midi-boxing now, so I don't want to start learning assembly, so that would be my first stumbling block. I know there are trial versions in C code floating about, but I haven't seen any conclusionary results posted, so I am assuming it is still a work-in-progress. Can anyone who has tried it update here as to their experiences?

Also, am lost as to the type of interfacing between the keyboard and the core, so I would appreciate any input there.

And finally, when I get the keyboard running with velocity sensitivity, I think it would be only fair of me to look into getting the aftertouch in order.

So, big enough of a project, and as ever, look forward to your help and sharing my experiences!!

Go raibh maith agaibh,

Mark :)

I have read your post and wonder why you are interested in scanning the JW 50.  From the brief spec that I read, it would seem to be able to provide Velocity sensitive Midi On/Off Messages without modification.

Maybe I am missing the point.

Its a great machine, the JW50, or at least was in 1992 when I bought it. I want to use the case to buils a new system, both PC and MIDIbox based, but the system is all built onto one board, and I need the space for the upgrade.
