Use that to convert Midi's to mmf's to select which chord you want the phone to vibrate to. Also you can select when the LED flashes. I tried it on my s300, V200(Flashed v205) and my s105. Doesnt work for an s105.
you won't be able to make the ringtones that come with the phone vibrate, but if you make your own with psmplay, you can set a specific track to vibrate
For V200, I think it supports dead ringers (ringtone + vibrate). Just use psmplay and edit the channels, enabling the LED/VIB button or something in the options. It's in there (not 100% sure since my S100 doesn't support that feature).
