They are digital logic I/O or analog input. One of them can also be an analog output, but the DAC is only 5 bits.
OK, but one digital will work adequately for a MIDI Clock output for a arpeggiator or sequencer sync input, right?
32 levels for the analog output, perhaps controlled by CC Modulation, is clearly audiable, but gives at least some control over i.e. filter, volume or modulation on an analog synthesizer, so IŽd love to se that option in the (near?) future.
