2.2. MIDI SOCKETS MONTAGE

Pic. 2.2.1

The interface has both MIDI input and output.

Only MIDI input is necessary for the interface

operation. MIDI output need not to be installed –

see chapter 5. However, both MIDI input and

output (MIDI-IN and MIDI-THRU/OUT sockets)

utilization is more convenient for full

interconnection to MIDI system. Suitable place for

MIDI sockets is on rear panel of the instrument

(see pic. 2.2.1).

P

a) Drill two holes with diameter 16 mm for MIDI sockets to the wood rear panel of the instrument

– see pic. 2.2.2. Use sharp drill and work carefully so that the panel and a components inside the

instrument are not damaged during drilling!

3. TIPS FOR INSTALLATION

Pic. 3.1

a) Output MIDI – THRU/OUT

The VP330-KBD Interface has both MIDI input and

output. However, only MIDI input is necessary unconditionally

for basic operation of the interface (i.e. controlling the

instrument via MIDI commands). MIDI THRU/OUT output

socket need not to be installed if you don’t require transfer of

MIDI data to another MIDI devices (THRU function) or reverse

communication of the interface with host system (OUT

function). It this case, connector CN2 (M-OUT) on the

interface board will remain unconnected (see pic. 3.1).

b) Switch and indication LED

Pic. 3.2

Installation of bunched cables of switch and indication

LED isn’t also necessary unconditionally. It is not needed to

install the bunched cables if you don’t want to affect the

instrument’s panel by drilling. However, jumper must be

plugged on pins Nr. 3 and 4 of CN3 (CTRL) connector on the

interface board in this case (see pic. 3.2).

It is also possible to install only indication LED on

instrument’s panel. In this case, remove (cut-off) switch from

bunched cables and connect (solder) together two black and

one blue wires leading to the switch originally and insulate the

connection of the wires (see pic. 3.3).

Pic. 3.3

In such “non-invasive” implementation the interface works following way: Immediately after the

instrument is switched on, the interface is activated but it still doesn’t affect the instrument – the

instrument can be used like without the interface. As soon as the first MIDI command is received at

interface’s MIDI input, the indication LED lights red and the interface starts to control the instrument’s

keyboard and pitch shift circuits. If you want to switch the interface off, so that it had no affect on the

instrument, the interface must be reset. It can be done by turning off and on the instrument or by MIDI

command “HW Reset” sent to the interface (see user manual of the interface).
