This is for an event at my place of worship.

I have a folder full of .wav files that we want to be triggered by a keyboard - I'll be using my PSR-S910.

So I'm looking for a free or cheap software sampler for PC and a way that I can assign each of these .wav files to a note on my keyboard.

I know how to configure my keyboard and how to set up the MIDI. I just need help with the software and implementation.

Thanks in advance!
