This Midi Data Logger has a midi in and output set of connectors. You only need the input for reading the midi data but the midi output allows you to use your midi device(s) while monitoring the midi codes. The top line displays the 3 byte midi code in hex and will display any and all hex codes for midi messages. For your convenience, the bottom line displays the demo description of the hex code such as NOTE 36 ON CH 01 which is the note number, note on or off, and the midi channel number. All other midi messages simply display the hex code without the demo description. This device has two operating modes: one is continuous and the other stores each reading until you are ready for the next read cycle.

Any one building or designing virtual organs such as Hauptwerk will find this device to be invaluable.

This is very useful for checking your midi codes when installing and/or trouble shooting your midi setup, midi devices (such as our midi converters), midi expanders, midi keyboards, midi cables. It is especially useful for setting up and testing Hauptwerk and other virtual organs. Also, it is invaluable for stage performance midi equipment and cable setup and operation.
The description of the hex code is available for notes and program data and reads "unknown" for all other midi data at the present time. A midi code chart is enclosed for all midi hex codes.
