Midi no longer connects
EP-50's are notorious for problems with either the 4.65 voltage feed to the velocity sensitive keys or failure of the small zenner diaodes. Each key has a pair fo split circles on the circuit board under it. When you hit the key you connect each side of the circles and the harder you hit the keys the quicker the circuits close the louder the sound. Problem is if the voltage to either circle fails, due to bad solder, scratch on circuit board, failed diaode then the sound disappears. The fix is simple if you are knowledgeable on solder on circuit boards, can use a multimeter and can dissassemble and reassemble the keyboard. If you have to take it to a repair shop it is probably not worth fixing as this is not one of the better Roland products

Theres a good article at recordingreview.com. If you join which is free you have access to a lot of great information. You can download Midiox to troubleshoot your midi connections etc. Make sure that your transmit channel on your keyboard matches up with the receive channel in your program. Hope this helps.

Check that you don't have MIDI echo on in the DAW. If the MIDI data is echoed, it MAY be merging with the outgoing and when MIDI signals are merged in pieces instead of whole messages the data is corrupted. If you can look at the data stream with software, you should be able to spot the problem. Another problem might be excessive latency of the recording software. Make sure you do not have antivirus or antispyware programs running or network running. The Roland will spill data at much less rate and while the dd55 may overrun the DAW the Roland might not be able to. The key to the problem is to analyze the MIDI data stream that is being recorded.

Hi you'r NOT stupid, it's just that Roland doesn't like people mixing stuff up, they want you to use their gear only, accordingly, you must dump the Axiom, MIDI and get a Roland one... You really need to keep it all one brand as it were then there will be NO problems at all... Not all MIDI are created equal, as it were, and using the Roland one will allow full functionality to be provided by the input unit. This unit is more the more modern one of the RD700 series, and the older, RD700 wan't all that fussy about the interconnections but your new one is. In any event I do know that sticking within the same brand name always sorts things out for whatever reason?
