This is a serious problem and a deal breaker for me.
If I plug my midi cable into Midi channel One of the Audya 4, all voices play normal with no vibrato effect. However, the keyboard will NOT trigger the Arranger with this setting even though I go into MIDI settings and set the kb trigger to Input 1.
If I plug my midi cable into midi channel Two (KB) and set the kb trigger to Input 2, all lead voices have vibrato; whether piano or organ or whatever.
I have checked all modulation settings, midi-clock/sync settings of my trigger keyboard (Yammy Motif XS) etc.
Also, I am unable to use the Keyboard Split function to change the split point USING THE KEYBOARD. This tells me something is wrong with the MIDI configuration between my keyboard and the A4 module.
