I just got the Vestax VCI-100 and I imported the VCI-100 TK PRO TSI from vestax.com.

By pushing all the buttons on my controller it doesn't seem like they're all assigned. For instance, I don't know how to turn on effects and use them. In the MIDI Mapping preferences, I see that there are many assigned controls with "effect"; "Effect Param 1-3", "Effect Param Reset" and "Effect Button 1-2". First of all I don't know the difference between these controls. Second, they are assigned for notes like "Note D#5 (ch1)" which I have no idea which of the buttons on my controller that is.

I hope someone can help me figure out how to know which buttons are which and what the different controls do.

Thanks in advance
