Sequential Prophet VS - MIDI FUNCTIONALITY

84
Any notes played on the master will also be played on the slaves. Playing
the slaves, on tine other hand, has no eect on any other instrument in the
“chain,” unless their MIDI OUT is connected to another instrument’s MIDI IN.
In Figure 14-1, the rst slave’s MIDI OUT can drive the master’s MIDI IN. This
enables either keyboard to play the other. The rst slave is unable to play the
second slave though, because it does not transmit MIDI data over its MIDI
THRU.
It is not a good idea to connect a slave’s MIDI THRU to the master’s MIDI IN,
because doing so will cause all notes played on the master to reappear at
its own MIDI IN, and if an arpeggiator or sequencer is running, this can add
confusion.
Generally, whatever appears at an instrument’s MIDI IN jack appears at its
MIDI THRU, but not at its MIDI OUT.
Besides key information, there are other MIDI messages which can be sent
from instrument to instrument such as the following:
Program Selections
Selecting a program on the master sends a “program change” message to any
slaves in the MIDI chain, which then change programs. Program selections
must be enabled on master and slave(s). (See MIDI OPTIONS, later in this
section.) Since instruments may organize their programs in banks of ten
(like the VS), eight (Prophet-5), or even twelve (Prophet-2000), the slave may
not display the same program number as the master. In any case, for each
program selected on the master, there is a corresponding program on the
slave.
Wheels
Using the mod or pitch wheels on the master causes similar “wheel
movement” on the slaves. Many synthesizers have dierent wheel ranges, so
it may be necessary to adjust Pitch Wheel Range on the VS to match other
instruments’ ranges. Mod and pitch wheels must be enabled on master and
slave(s). (See MIDI OPTIONS.)
MIDI Clock
Instruments featuring arpeggiators (like the VS), sequencers, and the like,
usually transmit or recognize “MIDI Clock” messages as non- MIDI equipment
would send or receive traditional clock or trigger signals. This allows several
MIDI sequencers, arpeggiators, or drum machines to play in sync. MIDI clocks
are encoded messages, however, and can only drive MIDI equipment. Many
other timing messages are transmitted and recognized by the VS, and are
explained under “SPECIFICATION,” later in this section.
