TS8-MS Quick Setup
For full product information go to http://midi-overdrive-switcher.becosfx.com/
1. Power off pedal (battery or DC power adapter) and set the Multi Function rotary HEX
switch inside to a position corresponding to the desired setup setting.
2. Push and hold the Footswitch while power on pedal and continue to hold the Footswitch
for at least 3 seconds, until visual indication of LED's confirm saving the setting.
3. Power off pedal. The setting is saved. Power on pedal and start using it.

Buffered Bypass
(factory default)
HEX = A
Silent "soft switching" using FET transistors
placed between input and output buffers. No
sound loss even with long connection cables.
Recommended and used as factory default.
Relay True Bypass HEX = B
Mechanical switching using relays controlled
by a microcontroller. In bypass or without
power, signal goes directly from input to
output. Avoid long connection cables.

Latching Switching
(factory default)
HEX = 0
External Relay switching with latching. When
relays are ON, Tip-to-Ground or/and Ring-toGround are shorted and mentained until OFF
command is initiated.
Momentary
Switching
HEX = 1
External Relay switching is momentary ON.
Tip-to-Ground or/and Ring-to-Ground in the
External Switching 1/4TRS Connector are
shorted momentarely (100ms ON, then OFF)
for either "ON" or "OFF" relay commands.

* After setting procedure is finished (power off), you may need to set the Multi Function switch to a different in operation position than
the one used for setup.
** During setup, LED blinking is continuous until power off. Steady lit LED's remain as such until power off.

Footswitch Action
You can use pedal footswitch to perform the following actions:
1. Change pedal state: Bypass / Overdrive / Extended (long-
push; pedal state is preserved; only External Switching
Relays are affected).
2. Switch amp channel with each pedal state - see Multi
Function switch and External Switching Relay switching
pattern Table 1.
3. Transmit MIDI Program Change with each pedal state - see
Multi Function switch.
Multi Function Switch
The Multi Function switch inside pedal has 16 positions and it is used to:
1. Set MIDI Channel for Transmit or Receive function (see: How to set pedal to transmit or receive
MIDI).
2. Assign External Switching Relays switching pattern, when pedal footswitch is used.

Set TS8-MS pedal to transmit or receive MIDI
Inside the pedal there are two small 4-pin sockets: one socket is for MIDI Receive function (factory default) and another
for MIDI Transmit function. The external 5-pin MIDI connector is connected to the circuit board on one socket or the
other, through a 4-wire jumper cable. Only one function can be used at a time.

How to use TS8-MS
TS8-MS is an analog overdrive pedal which can be enabled with midi, is a MIDI switcher and a MIDI transmitter in a
box. All of the above function simultaneously in either setup mode. Here are several examples of how you can use it:
Footswitch Action - use TS8-MS as analog overdrive and amp channel switcher
Footswitch Action - use TS8-MS as analog overdrive, switch amplifier channels
and transmit MIDI Program Change messages, all at once
External MIDI Control - switch TS8-MS analog overdrive and amp channels with an external MIDI Controller
