1. GENERAL INFORMATION

VP330-KBD MIDI interface allows full integration of Roland VP-330 instrument to MIDI system.

Interface affects instrument’s keyboard and pitch shift function. All original features of VP-330

instrument remain unchanged after the interface installation and the instrument can be used the same

way as without interface installed. Simplified block functional schematic of the instrument after the

interface installation is shown on pic. 1.

2. MIDI INTERFACE INSTALLATION

Installation of the interface into Roland VP-330 instrument is very easy. If you follow the

instruction from this manual carefully, there should be no major problems during the installation

procedure. Detailed steps of interface’s parts installation is described in chapters below. Please keep

these instructions accurately to not damage the instrument.

Attention! Disconnect the instrument form the mains prior to the installation.

Otherwise, there is a risk of the electric shock!

Attention! Observe precautions for handling electrostatic discharge sensitive devices!

The producer is not responsible for any eventual mechanical or electrical damage of

the VP-330 instrument caused by the infringement of the described installation

procedure or by careless manipulation during the installation of the MIDI interface!

2.1. OPENING THE INSTRUMENT

a) Unscrew five screws on bottom side of the instrument (pic. 2.1.1). Keep the screws. They will

be used again after the MIDI kit installation is finished. Remark: These screws hold instrument’s

keyboard to bottom plate of instrument’s cover.

b) Unscrew six screws on top panel of the instrument (pic. 2.1.2). Keep the screws. They will be

used again after the MIDI kit installation is finished. Remark: These screws hold instrument’s top panel.

Pic. 2.1.1 Pic. 2.1.2

c) Carefully open the instrument - lift off the instrument’s panel. Now, all instrument’s parts and

boards needed for the interface installation are accessible (pic. 2.1.3).

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!

b) Clean the edge of both holes with small rasp after drilling. Clean all sawdust and rasping

from the inside of the instruments, they can cause malfunction of some electro-mechanical

components of the instrument. Please clean the instrument carefully!

c) Get flat connectors of MIDI cables through the holes in the panel (pic. 2.2.3). Both MIDI cables

are identical and they can be swapped.

Pic. 2.2.3 Pic. 2.2.4

d) Insert DIN sockets of the cables into the drilled holes and fix them to the panel using four self

tapping screws from the interface accessory (pic. 2.2.4). Make small holes for the screws with small

drill or a peak before (pic. 2.2.5).

e) It is recommended to label the DIN sockets ("MIDI IN", "MIDI THRU/OUT" – for example) with

self-adhesive foil glued near to the sockets on the instrument’s panel (pic. 2.2.6).

Pic. 2.2.5 Pic. 2.2.6

2.3. SWITCH AND INDICATION LED MONTAGE

Pic. 2.3.1

There are two elements for the interface

control - tumbler switch and bi-color LED. They

are not necessary unconditionally for the interface

operation. They need not to be installed – see

chapter 3. However it is more convenient for

easier device control to use them. Suitable place

for control elements is on the top panel of the

instrument (see pic. 2.3.1).

P

a) Drill one hole with diameter 6,5 mm and one hole with diameter 6 mm to top panel of the

instrument - see pic. 2.3.2. Work carefully, so that the panel and components inside the instrument

are not damaged during drilling!

b) Clean the edge of both holes with small rasp or with point of bigger drill after drilling. Clean all

iron sawdust and rasping from the inside of the instruments, they can cause short circuits or

serious electrical damage if left in the instrument. Please clean the instrument carefully!

c) Insert tumbler switch into the 6 mm hole on the panel (from inner side) and fix the switch to the

panel with two nuts (pic. 2.3.3). The switch must be positioned so that the not-connected lead of the

switch is near the instrument’s rear panel (pic. 2.3.4).

Pic. 2.3.3 Pic. 2.3.4

d) Insert LED holder into 6,5 mm hole on the panel. Plant lock ring of LED holder to bi-color LED

on bunched cables. Then insert two-color LED into holder (from inner side) and fix it by over-thrusting

of the ring on the holder (pic. 2.3.5).

e) It is suitable to label the LED and the switch ("MIDI - ON" for example) with self-adhesive foil

glued near to the sockets on the instrument’s panel (pic. 2.3.6).

2.4. MONTAGE OF POWER SUPPLY BUNCHED CABLES

Pic. 2.4.1

Power supply bunched cables are

equipped with flat 3-pin connector on one end

(pic. 2.4.1). All wires outgoing from this

connector must be connected to instrument’s

power supply board (labeled PSH42 / PSH43 in

dependence on mains supply voltage of the

instrument) as shown on pic. 2.1.3.

a) Unscrew four screws from PSH42/43 power supply printed circuit board (pic. 2.4.2). Keep the

screws. They will be used again after the cable installation.

b) Unplug five connectors of bunched cables from the board (pic. 2.4.3). Then remove the power

supply printed circuit board from the instrument and put it solder side up (pic. 2.4.4).

Pic. 2.4.2 Pic. 2.4.3

b) Solder the black wire Nr. 1 (GND) to ground potential – to one of solder pads from 2 to 10 of J3

plug on the power supply board from the solder side (pic. 2.4.4). Do not use pad Nr. 1 – there is -10V!

c) Solder the red wire Nr. 2 (+15V) to stabilized supply voltage +15V – to one of solder pads of J1

plug on the power supply board from the solder side (pic. 2.4.4).

d) Solder the blue wire Nr. 3 (-15V) to stabilized supply voltage -15V – to one of solder pads of J2

plug on the power supply board from the solder side (pic. 2.4.4).

e) Return the power supply board to the original position and fix it back to bottom plate of the

instrument with four original screws. Keep orientation of the board (pic. 2.4.5).

f) Plug five connectors of bunched cables back to the board (pic. 2.4.5). Be sure that J1 and J2

are not swapped (J1 has red wires, J2 has blue wires).

2.5. MONTAGE OF FLAT CONTROL SIGNALS CABLE

Control signals cable is equipped with flat 50-pin connector on one end (pic. 2.5.1). Wires

outgoing from this connector must be connected to several points of the AGH19 (AGH17 in older

model) printed circuit board of the instrument as shown on pic. 2.1.3. Individual wires of control signals

cable will be connected in accordance with table 1 and pic. 2.5.1.

Pic. 2.5.1

Split up free end of the cable (by ripping or cutting) to individual groups of wires and adjust their

lengths as necessary during the cable installation. Then stripe ends of the wires in length about 2 mm

and tin them. Note that wire Nr. 1 (terminal) is signed with red color.

a) First, FLH16 board must be removed in order to access to AGH19 (AGH17 in older model)

board: Unscrew four self tapping screws from metal holder of FLH16 board (pic. 2.5.2). Keep the

screws. They will be used again after the cable installation.

b) Unplug one connector from the little board on rear panel of instrument and three connectors

from the FLH16 board (pic. 2.5.3) – mark each of the connectors before, so that they are not swapped

when reassembling. Then pull off the holder with FLH16 board out of the instrument.

Pic. 2.5.2 Pic. 2.5.3

c) Lift the keyboard and slide it out of the instrument (pic. 2.5.4). The keyboard is detached

already. The main oscillator board AGH19 / AGH17 is now accessible.

d) Unscrew ten screws from AGH19 board (pic. 2.5.5). Keep the screws. They will be used again

after the cable installation.

e) Unplug all sixteen connectors J1 to J16 from AGH19 / AGH17 board (pic. 2.5.6).

f) Remove the AGH19 / AGH17 board from the instrument (pic. 2.5.7) and put it solder side up.

Be careful during this and all next operations - note that electrostatic sensitive components are on

the board. Use conductive pad on the desktop and follow the rules for working with CMOS circuits!
