Bank has 16 pads with empty wavs and midi in/out routed to corresponsing channels. Plus a 17th pad that has single cycle sine wave loaded that can be used as a tuner;
Put it on the same link group as the sample/sound you want to tune, change the default note that the pad plays to what ever note you want to tune your sound to, then just play your sound while changing its tune and you can hear when it matches with the sine wave.

Single cycle sine is from adventurekids free library: https://www.adventurekid.se/akrt/waveforms/ . I highly recommend checking it out.
