Hi Tony, you didn't say which model Digitech Vocalizer you are using. I own the Vocalist Workstation EX (use it with my Technics KN5000), but I think that all models operate more or less the same.

Be sure to select the "Key and Harmony" mode on your Vocalizer. Make sure that the midi receive channel (midi in) setting for "Key and Harmony" on the Digitech Vocalizer is set to the "SAME" midi channel as you assigned on your EM200 keyboard for sending arranger chord data (midi out). Make sure that the midi channel you select is NOT being already used (on your EM2000) for sending out note data, controller data, etc. The midi channel you assign must be dedicated for arranger chord data ONLY.

In addition to checking the above settings, make sure that you DON'T connect the "midi-out" on your Vocalizer to the "midi-in" of the EM2000. This could possibly cause a midi "looping" problem which may produce similar symptoms that you descibe.

Good Luck,
