I've tested all channels.. There is no problem between 202 and 303.. it's between 202 and 383.
It's wierd because there isn't that many settings to chance. 202 is set to use channel 2 and it's set to external. If I hook 383 to 202 there's no midi traffic. If I hook MC-303 to 202 with those same settings 202's sequncer send info nicely to MC-303.
Freebass doesn't have any settings.. just MIDI IN and that's it.
When I hook 383 to MC-303 and send midi data from channel 2 to freebass it works like a charm.
The only possibilitie is that DR-202's MIDI out lacks something that MC-303's MIDI out has. It sounds wierd because MC-303 recognise DR-202 sequences but not Freebass. Can there be some different with groundings.. That MC-303's MIDI out has for example all the wires connected and all grounds and DR-202's MIDI out has just needed minimal wires.. I dunno..
Freebasses MIDI activity light doesn't even lit when I connect it to 202.
