Hey Ethan,
Sorry to hear about those problems - it's either a hardware fault or you have MIDI controls that aren't working as expected. Open rekordbox, click the MIDI button (top right), then click the DEFAULTS button to reset the configuration. See if that helps - if it doesn't, please file an inquiry ticket here and our support team will gather some additional information to assist you in resolving this issue.
