External connections include 2 unbalanced 1/4-inch "MIX" (left and right channel) and 2 unbalanced "DIRECT" (left and right channel) TS connector jacks. Sounds are normally routed to the MIX outputs but can instead be routed to the DIRECT outputs when required. There is a 1/4-inch stereo headphone jack, a 1/4-inch jack for the sustain (hold) pedal and a 1/4-inch jack for sequencer click output, useful as a metronome when playing along with the sequencer. Four 1/4-inch control pedal jacks have configurable functions, including the ability to adjust patch volume, patch cutoff frequency, effects levels, organ speaker rotation simulation, stepping through patches, and so forth. There are three 5-pin MIDI ports (IN, OUT, and THRU).
