Extend maximum track length in DJ Patch?

I’m trying to load song-length tracks into DJ Patch. (About four minutes long each.)

DJ Patch cuts off tracks around the one minute mark.

I can’t tell whether the sample-length shortening happens when the patch loads the samples, or somewhere on the play end.

If there’s a simple PD edit I can make to extend the maximum track length, can you tell me what it is?

thank you,
