What roland modules have the octoban and roto tom drumsor can you buy you sound card that has them and put it into your td-10 module?

The Roland TD-10 module does not come with built-in sounds for Octobans or Roto Toms specifically. However, you can use external sound libraries or sample packs that include these sounds and trigger them via the TD-10. Alternatively, you can explore newer Roland modules, like the TD-17 or TD-50, which may have more extensive sound options. If you want to use specific sounds, consider integrating a dedicated sound card or module that supports those drum types alongside your TD-10.
