[maxmsp] Re: Mapping acceleration values to soundfile amplitude

Hi
 I can't find a way to do this properly. Basically I aim to recreate the effect of mapping acceleration values to midi note velocity  E.g. the greater the incoming acceleration value the greater midi note velocity and therefore the louder the midi note played.

I know how to do this using midi, but I want to create the same effect using a wav soundfile instead. At the moment I have a soundfile being triggered at one constant volume, but I want the output to be altered depending on the incoming acceleration force. 

Please help!
