Programmable Bypass

Introducing the JMK Programmable Bypass Looper

• 5 True Bypass loops for switching either single or multiple effects in and out of a signal

chain. These loops feature relay controlled true bypass, which completely removes

unused effects from the chain, as well as operating with little or no noise or popping.

• Four banks hold ﬁve programmable presets in each bank. These presets are made up

of any combination the ﬁve true bypass loops in sequential (1-5) order.

• Each Preset gives the ability to allow a user to switch several effects on or off at once

without having to do the typical ʻtap dancing actʼ that conventional bypass units still

rely on. Each set of combinations is accessed using ﬁve loop switches with dual colour

LEDs that indicate both which preset and which loops are on or off.

• The ʻﬁrstʼ bank is dedicated to be used in ʻmanual mode.ʼ Manual mode allows the

user to turn each of the ﬁve true bypass loops on or off as a typical bypass unit would

allow. There are no presets in this mode, which allows a user to simply choose a

combination of loops on the ﬂy without needing to program.

• The bank switch cycles through the ﬁve banks available (manual mode plus preset

banks A through D) and is also used for programming each preset. It is accompanied

by an RGB LED indicating which bank is currently active with ﬁve different colors.

• The Programmable Bypass Looper is easy to program! You only need to use your feet

to program any preset - you can do so while standing and holding your instrument.

• The ﬁfth loop can also be set, using internal jumpers, to be used as a switch for an

external device. This feature is designed to be used to switch functions on an amp on

or off, or for switching on any device that uses an open/closed latching switch between

tip and ground.

• The Programmable Bypass Looper also features a Midi Output option, which allows

the user to program a midi controllable unit to work in conjunction with the presets in

each of the 4 programmable banks of the Programmable Bypass Looper. In Manual

Mode, Midi Output is inactive. Currently, there is no midi input support available.

• For power, the Programmable Bypass Looper runs on standard 9VDC tip negative

power supplies. The estimated amperage use of the unit is under 400mA.

Page 3 How to setup your Programmable Bypass Looper • Step One: Each Loop has a Send and Receive jack. Use a patch cord to connect each Send Jack of each loop to the input of each pedal you want in the loops. Use more patch cords to connect the Receive Jack of each loop to the output of pedal that corresponds.

Page 5 Once the Looper is setup, your instrument is plugged in, and your ampliﬁer is turned on, you will need to learn to use the Programmable Bypass Looper. Weʼve done our best to make itʼs operation is as intuitive and simple as possible. There are a few key features that you will need to understand.
Page 6 Using the Midi Output Using the Midi Output of the Programmable Bypass Looper will allow you to utilize the Midi functions of any effects you utilize. Here is some useful info to help you understand how this functions: • First, ensure that the Midi Output of the Programmable Bypass Looper is connected via a 5 pin Midi Cable to the Midi Input of whatever effect you desire to control.

Page 8 Consult your device or amp for the required switching scheme needed to determine if the Programmable Bypass Looper is capable of handling your switching needs, and which jack to utilize. Currently, TRS switching jacks are not supported, so keep that in mind if when using this element of the Programmable Bypass Looper.
