I've bought a second hand Technics KN2000, but I've got two little questions about it. Maybe anyone around here can help me out?

My first problem is that the messages that appear when I try to clear a song or a track in the sequencer are in French. However, when I switch the language option in the help menu from English to German, these messages appear in English. All other messages do appear in English.

The second question is a lot easier I think. It is possible to attach 2 footswitches to the keyboard, but the ones that Technics sells don't look very sturdy to me. So I was wondering, if it is possible to use a footswitch from e.g. Roland or Yamaha?

Thanx in advance
