In addition to choosing sounds from the front panel, all of the sounds in the JV-2080 can be accessed through MIDI. There are 128 Program Change messages available in MIDI. For instruments that contain more than 128 sounds, Bank Select messages (continuous controllers 0 and 32) are used to select groups (banks) of Patches. The JV-2080 uses controller 0 to select the main Patch bank that you want (e.g., internal memory, card, or expansion board), then it uses controller 32 to choose the appropriate "sub-bank" (e.g., expansion board A, Patches 1-128). Software sequencers (e.g., Cubase, Logic, Performer, Vision, Cakewalk) often have built-in Patch lists for various MIDI instruments. Simply configure your software so it recognizes it is working with the JV-2080. A Patch list is usually accessed in a Patch column within the software.
