iRig Stomp I/O is a guitar pedal board that works as an high quality MFi audio interface with onboard physical controls. iRig Stomp I/O is the perfect controller for AmpliTube: it has two main function modes, Stomp and Default. In Stomp mode you can turn on and off stomps in AmpliTube; in default mode you can surf among the AmpliTube presets. iRig Stomp I/O can be also used as a standard MIDI controller for other app/SW: indeed, you can send MIDI control change messages and MIDI program change messages that allows you to control other hosts. And thanks to the external MIDI IN/OUT ports you can also connect external MIDI devices. Also  you can use iRig Stomp I/O as a stand-alone controller (without an host connected) to command external pedals or effects that accepts MIDI messages. The DC input barrel provides power to the iRig Stomp I/O when connected to an iOS device and at the same time charges the connected device. When connected to a Mac/PC all the needed power is provided by the USB.

Installation and setup

iRig Stomp I/O can be USB bus powered or powered with the external PSU (included).

iOS: when connected to an iOS Device the external PSU is needed. The external PSU will charge the iOS Device’s battery. The USB port can supply power (to the iRig Stomp I/O) when connected to iOS devices (iO device will not be charged).

USB: typically, when connected to an USB host (MAC, Windows), all the needed] power is provided by the host. If the connected host is not capable to provide the required power the PSU may be needed.

iOS Devices:

1. Connect the Mini-DIN to Lightning cable to the iRig Stomp I/O port and to the iOS device port.
   
   

2. Download and launch AmpliTube App;
   AmpliTube 4 Deluxe, 4 T-RackS processors, Mic Room and Ableton’ Live 9 them for Mac/PC, AmpliTube and AmpliTube Acoustic for i0S. VocaLivc iOS and Mic Mic Room for IOS.

3. 3. Connect a microphone or an instrument to the input combo jack. If the microphone you are using requires external phantom power, activate the 48V switch.
   
   

4. Adjust the input level with the gain potentiometer.
   
   

5. Connect a mixer, an amplifier or a PA system to the stereo line outputs. It is possible to control the output volume with the Volume potentiometer on the top panel. These are floating balanced output. This kind of output approximately simulates a floating transformer winding; if both hot and cold outputs are driving signal lines, then the outputs are balanced, as if a centre- tapped output transformer were being used. This system has the advantage that it can give the same level into either a balanced or unbalanced input without rewiring connectors. These kind of outputs are also perfect to route the onstage signal to a mixer without the need of a DI box, ensuring a loud and pristine signal.
   

6. Connect your headphones to the headphone output. It is possible to control the output volume with the Volume potentiometer on the top panel.
   

7. If needed, connect up to two footswitch/expression pedals to the TRS connector on iRig Stomp I/O.
   

8. If needed, you can connect external MIDI devices to the physical MIDI ports (Input/Output.

MAC/PC :

1. Connect the USB cable to the iRig Stomp I/O port and to a free USB port on  your MAC/PC (the required power is supplied by the USB host).
   

2. Download and launch the AmpliTube App.

3.  Connect a microphone or an instrument to the input combo jack. If the microphone you are using requires external external phantom power, activate the 48V switch. Adjust the input level with the gain potentiometer.

4.  Connect a mixer, an amplifier or a PA system to the stereo line outputs. It is possible to control the output volume with the Volume potentiometer on the top panel.

5. Connect your headphones to the headphone output. It is possible to control the output volume with the Volume potentiometer on the top panel.

Operating modes

DEFAULT MODE


STOMP MODE

STANDALONE

iRig Stomp I/O can operate as:

• dedicated controller for AmpliTube app. When connected to AmpliTube, the iRig Stomp I/O allows you to recall presets (Default mode) or turn on/off pedals in the AmpliTube chain (Stomp mode). It is also possible to control the Looper and the Tuner on AmpliTube;
• generic Audio/MIDI interface and foot controller. With a generic host, you can use iRig Stomp I/O as a generic MIDI controller. This allows you to send generic MIDI messages to the host;
•  stand-alone MIDI foot controller. With no device connected, the iRig Stomp I/O can be used to send MIDI messages thru the MIDI out port.

Live Mode

Using iRig Stomp I/O with AmpliTube

When connected to a device running AmpliTube you can access to a full set of controls. Below we describe the operational mode when the app/software AmpliTube is running.

USB MIDI port : Make sure to have selected “iRig Stomp IO Control” as MIDI IN/OUT port.

Preset mode

MIDI CH 1

The iRig Stomp I/O has two main modes: Preset and Stomp. To switch between the two, simply press simultaneously footswitches 3 and 4 for more than 1 second. When in Stomp mode, the LED on the top panel will light up red.

Launch AmpliTube and tap on the LIVE section:

The LIVE section will appear in the preset (default) mode:

In this mode, the 4 foot switches send Program Change (PC) messages in bank of four (e.g.: from 0 to 3). By pressing and holding the footswitch 2 for more than 1 second the bank increase of 1. Now the 4 foot switches send PC messages increased of one bank (e.g: from 4 to 7). By pressing and holding the footswitch 1 for more than 1 second the bank decrease of 1. Now the 4 foot switches send PC messages decreased of one bank (e.g.: they’ll return to send PC 0 to 3). The banks can be increased until reach PC 127. Each time a bank up/down is performer all the 4 LED of the foot switches turn on in sequence (from 1 to 4 in case of a bank up; from 4 to 1 in case of a bank down).

This mode is particularly useful to navigate among the AmpliTube presets.

MIDI CH 1

Footswitch LED 3 shows you the status of the track:

Tuner

MIDI CH 1

To access the AmpliTube tuner press and hold footswitch 3 for more than 1 second (to exit the Tuner press any of the 4 footswitches).

When iRig Stomp I/O is in tuner mode the footswitche’s LEDs show the tuning status.

Tap tempo

MIDI CH 1

To access the AmpliTube tap tempo press and hold footswitch 4 for more than 1 second (to exit press switch 1, 2 or 3). When iRig Stomp I/O is in tap tempo, use the footswitch 4 to tapping the tempo. Each pression of the Switch 4 will send a Sysex:

*0xF0 0x7E 0x00 0x21 0x1A 0x01 0x03 0x41 0x50 (0x31 0x32 0x33 0x34) 0xF7**

• (example) corresponding to 132,4 bpm.

MIDI IN/OUT ports

With AmpliTube running you can use the physical MIDI IN/OUT ports to send or receive MIDI messages from/to external MIDI devices.

On the MIDI OUT port will be sent all the MIDI messages generated by the iRig Stomp I/O; the MIDI IN port will send the MIDI messages to AmpliTube.

Audio/MIDI interface and foot controller

Using iRig Stomp I/O as a generic MIDI controller

With a generic host (i.e: without AmpliTube), you can use iRig Stomp I/O as a generic MIDI controller. This allows you to send generic MIDI messages to the host. As generic controller you can use the default and the stomp mode: the looper and the tuner mode will not work.

USB MIDI port : Make sure to have selected “iRig Stomp IO Port 1” as MIDI IN/OUT port.

Default mode

MIDI CH 1

The iRig Stomp I/O has two main modes: Default and Stomp. To switch between the two, simply press simultaneously footswitches 3 and 4 for more than 1 second. When in Stomp mode, the LED on the top panel will light up red.

When in default mode, as generic controller, the 4 footswitches send Program Change (PC) messages in bank of four (e.g.: from 0 to 3). By pressing and holding the footswitch 2 for more than 1 second the bank increase of 1 position. Now the 4 footswitches send PC messages increased of one bank (e.g: from 4 to 7). By pressing and holding the footswitch 1 for more than 1 second the bank decrease of 1 position. Now the 4 footswitches send PC messages decreased of one bank (e.g.: they’ll return to send PC 0 to 3). The banks can be increased until reach PC 127.

Each time a bank up/down is performer all the 4 LED of the footswitches turn on in sequence (from 1 to 4 in case of a bank up; from 4 to 1 in case of a bank down).

The 4 footswitch’s LEDs turn on Red when a CC value 127 is sent from the Stomp I/O and turn off when a CC value 0 is sent from the Stomp I/O.

Expression pedal

The on-board expression pedal send a MIDI Control Change message (CC#11) and it can be freely assigned to any control on the host, as well the virtual switch (CC#26).

Tap tempo

MIDI CH 1

When iRig Stomp I/O is in tap tempo, use the footswitch 4 to tapping the tempo. Each pression of the Switch 4 will send a Sysex:

*0xF0 0x7E 0x00 0x21 0x1A 0x01 0x03 0x41 0x50 (0x31 0x32 0x33 0x34) 0xF7**

• (example) corresponding to 132,4 bpm.

MIDI IN/OUT ports

As generic controller you can use the physical MIDI IN/OUT ports to send or receive MIDI messages from/to external MIDI devices.

On the MIDI OUT port will be sent all the MIDI messages generated by the iRig Stomp I/O and by the host; the MIDI IN port will send the MIDI messages to the host.

Stand alone MIDI foot controller

With no device connected, the iRig Stomp I/O can be used to send MIDI messages thru the MIDI OUT port. Messages sent are the same of generic MIDI controller, but all the MIDI messages are routed to the MIDI OUT port.

To use the iRig Stomp I/O as a stand alone controller, keep pressed the footswitch 1 while connecting the external PSU : to indicate that iRig Stomp I/O has been initialized in stand alone mode, all the 4 footswitch’s LEDs blink red 3 times and the red LEDs of the meters turn on red.

In this mode, all the message sent are the same as per paragraph 4 of this manual (Audio/MIDI interface and foot controller), with exception of the tap tempo message that’s not sent. The unit will start up in this mode each time it will be powered on: to exit the stand alone mode keep pressed footswitch 1 while connecting the external PSU.

Pedal calibration

The on-board expression pedal is factory calibrated to offer the best experience. Nevertheless, a user pedal calibration may be required. Before to perform the pedal calibration, bring the pedal to its minimum position. To start the calibration process keep pressed the footswitch 3 while powering up iRig Stomp I/O. When the iRig Stomp I/O is in pedal calibration the pedal’s LED blink alternatively in red and green: move the expression peda from its minimum to its maximum (pleas note that the calibration does not consider the virtual switch). To end the calibration, press any of the footswitches: if the calibration ended up successfully the pedal’s LED blinks for few seconds green, otherwise it will blinks for few seconds red to indicate that something gone wrong during the procedure.

External pedal inputs

iRig Stomp I/O sports two external pedal inputs that can be used to connect expression pedals or sustain pedals.

The external pedal inputs send:

MIDI CH 1

Audio meters

iRig Stomp I/O sports an input level meter to keep monitored the audio input signal, and a device output meter to keep monitored the signal coming from the connected host.

Bootloader

To access to the bootloader (only needed for firmware update), keep pressed the footswitch 4 while power up iRig Stomp I/O.
