You would need to leave Rank.Samples_MIDINoteNumIncrementFromPipesToSamples=0:
Samples_MIDINoteNumIncrementFromPipesToSamples: Determines which pipe sample files should be used for which pipes. A value of 0 would indicate that a pipe with MIDI note number 36 would use a sample with filename 036-C.wav, 37 would use 037-C#.wav and so forth. A value of 12 would indicate that pipe 36 would use sample 048-C.wav, and -12 would indicate that pipe 36 would use sample 024-C.wav.If the samples are to be played at approximately their original pitches, then this value should normally be set to 0, but other values can be used to re-pitch or 're-voice' sampled ranks to different pitches.
Also set Samples_RankBasePitch64ftHarmNumIfAssumedTunedToConcertPitch=0 to read the stored pitches from the files.
