Drummers can connect to the DB-90 via Roland V-Pads or the built-in microphone. Guitarists and Bassists connect directly to the DB-90 with no additional action required, following the rhythm through headphones.

Almost any type of musician can benefit from the features of the DB-90. For those looking to sync with an external sequencer for more sophisticated sound accompaniments, they can do so with the MIDI input of the DB-90. This stage orientation feature is particularly useful for Drummers.
