Is there anyone out there who knows the instrument that was used to record this sound? (the dutch train station sound)My guess is some sort of bell mechanism, but i can't quite say.
It is the 'Bell' voice recorded from a polyphonic synthesizer or electronic keyboard. (The way the tones sustain do not support a natural bell sound hypothesis.) I have encountered this patch on Yamaha keyboards and on Korg keys as well.
The first two sounds are definitely made by the same thing, possibly a bell. The third could be a synthesiser or piano, or even electric organ.
