This is a non-standard MIDI key mapping for these instruments. PROBLEM: The DTXPLORER (for whatever reason) sends out the snare note on G2 (key 31) and the kick note on A2 (key 33). SYMPTOM: When connecting DTXPLORER to GarageBand using MIDI, the snare drum is silent and the bass drum triggers a sort of snare roll instead of a bass hit.
