I made a lyre with karplus strong:

karplusstrong.pd

It works pretty well, but with pitches above 600 Hz the spectrum becomes very rich, so that the sound becomes very metallic and the fundamental becomes increasingly hidden among the other pitches. What can I do about this?

@s.elliot.perez I think it's because your feedback delay can't go below 1 block, which at the default size of 64 is the period of about 689hz. Move a subset of your patch that includes both delay objects into a subpatch and declare a smaller block size using [block~].

@jameslo Hey, you were right. Thank you!
