Digital Connections Cannot Be Used
When Sync Source is set to “EXT,” the VS-880EX operates according to the
Clock signal (MTC) transmitted by the connected MIDI device. At such times, if
you also set the master Clock to “DIGIN1” or “DIGIN2,” the VS-880EX then
also attempts to operate according to the Clock (digital signal) from the exter-
nal digital device. This means the internal clock becomes mismatched. Thus, in
the present example, the slave VS-880EX (B) cannot record the digital signals
transmitted by the master VS-880EX (A).
When the master Clock is set to “DIGIN1” or “DIGIN2,” the VS-880EX operates
according to the Clock (digital signal) transmitted by the connected MIDI
device. You can thus make MTC the master Clock. However, in this case, the
slave VS-880EX (B) attempts to operate according to the MTC transmitted by
the master VS-880EX (A), while the master VS-880EX (A) attempts to operate
according to the digital signals transmitted by the slave VS-880EX (B). In such
instances, since this ends up in there being no reference clock, the VS-880EX
cannot operate correctly.
