Nobels MS-4 Owner's Manual

Owners Manual MS-4
- Introduction
There are still a lot of units (Amplifiers, footpedals...) which are
not able to be switched by Midi. For those cases we developed
the MS-4. If transmitting Midi program changes to the MS-4 four
independent units can be switched, of course they are able to be
switched by remote!
Please read this manual carefully!

1 Controls

(1) Switches 1..4
(2) Led + KEY 1 for Switch 1 or Midi RCV Channel
(3) Led + KEY 2 for Switch 2 or Switch Assign
(4) Led + KEY 3 for Switch 3 or M.Prot OFF
(5) Led + KEY 4 for Switch 4 or M.Prot ON
(6) Store key
(7) 9V Power Supply jack
(8) POWER ON / OFF
(9) MIDI IN jack
(10) MIDI THRU jack

2 Connection

.1 Connect a 9V DC power supply to the jack (7).
(Please check the polarity first!)
.2 Connect a midi cable from the MIDI IN jack (9) to
the midi unit which is able to transmit midi program
changes. (E.g. midi footcontroller Nobels MF-1 or
MF-2)
.3 The output of the SWITCHES 1..4 (1) can be
connected with standard cables to the remote or
footswitch jacks of the units to be switched.
.4 Other midi units can be chained via the MIDI THRU
jack (10).

3 First Setup (Midi Receive Channel)

Note: One midi unit transmit data, the other receives data. To
"understand" each other it is neccessary to set these units to the
same midi transmit / receive channel:
.1 While pressing KEY (2) switch the POWER SWITCH (8) to the
ON position.
.2 Then press the key (2) as often as the requested receive channel is
selected. The 4 LEDs (see table) shows the corresponding channel
1..16 or omni (all leds are flashing!).
.3 Press the KEY STORE (6) to save. Switch the unit off.

4 Latched Type or Momentary Switches???
Description: There are two kinds of switches: Latched type and momentary switches. Latched type
switches have two positions: One is ON the other is OFF. Momentary switches (or unlatched) making
"contact" while pressed. Mostly it is neccessary for multieffects! The MS-4 are able to simulate these
kinds of switches for the four SWITCHES 1..4. Additional it is possible to choose between 2 different
contacttimes which means the time a momentary switch is pressed! If possible always try to use the
shortest time. The logic of the SWITCHES can be changed between "positiv" or "negativ". It means that
the LEDs 1..4 are on when the contacts are closed and off when the contacts are open.
Configurate the switches
.1 While pressing KEY (3) switch the
POWER SWITCH (8) to the ON

position.
Sw. latched positiv
.2 Use KEY 1 for SWITCHES 1, use
Sw. Latched negativ
Sw. Unlatched pos.12ms
KEY 2 for SWITCHES 2 and so on.
Sw. Unlatched neg.12ms
Each of the SWITCHES 1..4 can be
Sw. Unlatched pos.100ms press key 4 times LED = flashes slowly short ON lang OFF
assigned to one of the 6 different
Sw. Unlatched neg.100ms press key 5 times LED = flashes slowly long ON
switchfunctions by pressing the
corresponding KEY 1..4.
See table!
.3 Press the KEY STORE (6) to save. Switch the unit off.
Look at this example:
I want to switch the reverb of my amplifier. If the footswitch is closed the reverb is off! But I want to
see if the reverb is on. In this case the corresponding LED 4 must be light up. For that I have to choose
a negativ logic. I hold KEY (3) "Switch Assign" and switch the MS-4 on. Now the LED 4 is on which means
the switch is set to positiv. I press KEY 4 once , the LED 4 is getting off. Now the logic is set to negativ.
Finally I have to press the KEY STORE (6) and switch the unit OFF. That's all!
6 Programming of the MS-4
The programming of the MS-4 is very easy
and can be done in 3 steps only as follows:
.1 Transmit your requested midi program change
from eg. a midi footcontroller to the MS-4:
This sets the MS-4 to the same program.
.2 Select the desired constellation of switching
with the four KEYs 1..4.
.3 Press the KEY STORE (6) to save. That's all!
Always a midi program change is received by
the MS-4 it recalls the constellation of the
SWITCHES you saved.
The MS-4 supports bank selects: It has a total
of 3 banks each with 128 programs. After
power on the MS-4 uses the first Bank by
default!
See chapter 12 "Midi Information"!
