Help - Midi - sound only on key release

[nash]

I have a Casio CDP-100 hooked up to Apple Mac Mainstage using a Midi-USB adapter.

I am only getting a sound during the release of a key, not on a press.

In Mac HD 'Applications->Utilities->Audio Midi Setup' I see the icon for 'Viewcon..' when I plugin the keyboard to the Mac.

I am pretty lost, can anyone help?

Update - if it's any help, I installed the Midi scanner MidiMonitor app from snoize,

it shows when I press a key 'Note Off'

When I release the key, it says 'Note On'

I am using one of these as the interface cable

ok so thats a really awkward problem... you can either 1. go into mainstage and switch every key so that its the opposite polarity, or... 2. unplug your keyboard and plug it back in.

personally i vote for #2

oh and also make sure that when you turn it on you aren't pressing any keys on the keyboard, and click learn so that mainstage recognizes they keys the correct way.

oh ok, so its also possible that its the midi to usb converter, sometimes the really cheap ones have big problems, i suggest getting maudios version its a higher quality, or if you already have another audio interface then just use the midi on that if it has it.
