There is a limit to how many "voices" the module can play, but that
usually manifests itself as a cutting out of an existing sound, I think.

It is possible it is a faulty kick drum pad - it would be difficult to
tell if it only fails when you hit the high-hat unless it does it
often enough to be reproducible.

Other than that, all I can suggest is to reduce the specific and cross
rejection settings on the kick drum.
