Midi presses
Each Midi-compatible instrument is usually equipped with 3 sockets:
OUT IN
OUT This socket outputs the Midi signals generated by the instrument and should therefore be
used when you want the instrument to become the controller (Master) of the system.
In this case, connect the Midi OUT socket to the Midi IN of the first instrument or device to
be controlled.
INthis socket receives the Midi signals generated by the Master unit and should therefore be used
when you want the instrument to be slave and therefore controlled by another unit.
If your instrument is the first Slave in the chain connect the Midi IN socket to the Midi OUT
socket of the instrument or Master device.
If your instrument is being used as a second or nth Slave you must connect the Midi IN to the
Midi THRU of the previous Slave.
THRUThis socket transmits an exact copy of the signal input into the Midi IN socket (usually the
signal generated by the Master unit) and should therefore be used when you wish to relay
Midi signals from a slave unit to other keyboards or devices.
In this case, connect the Midi THRU socket of the first Slave unit to the Midi IN of the second
and from this, again using the THRU socket, to the third and so on until the connection chain
is complete.
On some instruments or devices there is a fourth socket called Midi MERGE.
This socket is used by a slave unit to mix and transmit MIDI data to other units.
coming from the Master unit with the Midi data generated by the Schiavo instrument itself.
Midi Channels
The Midi System provides up to 16 channels of signal transmission on the same cable.
This is to allow several Slaves to be managed independently from a single Master unit.
on the other.
Let's imagine that we connect several Schiavi instruments to a multitrack sequencer.
In this case, it is possible to assign each track to a Slave by simply selecting on the
sequencer a different Midi channel for each track (e.g. track 1 on Midi channel 1, track
2 on Midi channel 2 etc.).
It is then necessary to set up each individual Slave to receive MIDI signals only from its own channel.
