okay, going slightly nuts. I've implemented my MIDI_Instrument_Controller object, and hooked it up to my table view, but it's complaining about implementing numberOrRowsInTableView and tableView:objectValueForTableColumn:row:. Fine, except that I very definitely have implemented them. I tried cleaning, and reloading classes in IB, to no avail. Has anyone seen this? Any solutions?

I'm going to have to hook up my NSTableView to set the *selected* port and channel for the MIDIInstruments, which means it's pretty much going to have to be loaded in the nib after all (since the MIDIInstrument has to respond to the selection made in the table). So, if I do that, and make the connections to Central_MIDI_Controller, as recommended, will the NSArrayController be able to add new instances of MIDIInstrument (and new rows to my table), which also have these connections? As I mentioned, I need an arbitrary number of MIDIInstruments.
