Page 3: Introduction
Introduction If you've purchased a MIDI Expression device, thank you for your support and I hope you enjoy using it. This manual gives you a good look at how MIDI Expression devices and the MIDI Expression Control application work. While they are both easy and intuitive to use, this manual is worth reading to familiarize yourself with their features and to discover aspects of their use that are not so obvious. -
Page 4: On-Board Led
LED is visible through the enclosures. The MIDI Expression iO (Mk 2) has 3 LEDs visible from the back of the unit. The top LED is a status LED, the middle LED indicates MIDI DIN in activity and the bottom LED indicated MIDI DIN out activity. -
Page 5: Getting Started
If you want to be able to controlled an application via MIDI, especially in Windows, you will likely need to enabled the MIDI Expression in the application's audio / MIDI setup. Every application is slightly different and yet basically idea is the same. Here are a bunch of screenshots showing how to enable MIDI Expression in various applications. -
Page 6: Control Application
Control Application As MIDI Expression devices have no physical buttons, any changes you want to make need to be done using the MIDI Expression Control application. The window of the application is scalable, so you can adjust the size to best suit the resolution of your display. -
Page 7: Device And Input Selector
The topmost part of the MIDI Expression control application is reserved for selecting the device and input you want to edit. When using a multi-input MIDI Expression, an input can be selected for editing by clicking on its graphic in the center of the top header. -
Page 8: Input Editor
Pedal Type Selector Each MIDI Expression input has a pedal sensing feature which allows it to automatically detect the type of pedal plugged in. When the SENSE control is underlined (default), pedal sensing is on and the pedal type is automatically selected, making the input plug ‘n play. -
Page 9: Using Expression And Hihat Pedals
(A) Input Polarity Switch Expression pedals can be wired in different ways. In order to support pedals from all manufacturers, the polarity of individual MIDI Expression inputs is reversible. There are three possible values for this control, “Auto’ (Default), straight, or reversed. Generally speaking, you should leave set to auto unless your particular pedal is having issues with the ‘Auto’... - Page 10 This control sets a limit on the number of values that are output per second. For example, if the control is set at 10 values / second, and you move the pedal from 0 up to 100, the MIDI Expression will slowly output values from 0 to 100 over a ten second period.

Page 11: Modes For Expression And Hihat Pedals
Modes for Expression and Hihat Pedals By default, MIDI Expression devices are setup to send Control Change messages when used with expression pedals and Hihat mode when used with a hihat controller. However, they can be configured to run in different modes and produce many different types of MIDI messages. -
Page 12: Note And Hihat Modes
The device will reoptimize its settings any time the MIDI Expression is plugged in, a new pedal is plugged into the input, your pedal is calibrated, or you adjust the Scantime setting. - Page 13 This is the note value that is output when the pedal is pressed down quickly. (G) Splash Note If you are using a hihat controller, you will also be able to trigger a second note by releasing the pedal very quickly after triggering a pedal note. MIDI Expression Manual page 13 / 31...
-
Page 14: Using Sustain Pedals
(A) Input Type This is used to tell MIDI Expression the type of switch your pedal uses. A latch style switch is one that alternates between two values, 'on' or 'off', every time it is pressed, much like a light switch in your home. -
Page 15: Modes For Sustain Pedals
Note On / Off messages can be used to trigger samples. INC / DEC Modes With MIDI Expression, sustain pedals and footswitches can be used to cycle though a range of Program Change or Control Change values. You can access this functionality by selecting the mode 'Control Chance INC / DEC' or 'Program Change INC / DEC'. -
Page 16: Dual Cc Mode
Keyboard Modes Key Command All current generation MIDI Expression devices support sending key commands. Legacy MIDI Expression devices with the mini-B USB connectors, however, do not. This mode allows your pedal to function like a computer keyboard. Clicking on the keyboard icon brings up an onscreen keyboard that allows you to set your key command. -

10, and long pressing the second switch will decrease the value by 10. Be sure to have the input type set to momentary to take advantage of the long press functionality. MIDI Expression Manual page 17 / 31... -
Page 18: Midi Routing
The settings are organized in vertical columns. Each column represents a source of input. The MIDI Expression iO in pictured below has 3 pedal inputs, 1 MIDI DIN In, and 1 USB MIDI In, for a total of 5 sources of input. -
Page 19: Midi Transformer
Transformer. Look here for more information. The MIDI Expression Quattro and iO each have three MIDI Transformer instances, You can switch between instances by clicking on the numbers at the top of the Transformer page. The single input MIDI Expression only has one instance. -

+1. If it the note is the F above middle C (695 it'll see the transpose value to +5. The amount of transpose can be set between -60 and +64. MIDI Expression Manual page 20 / 31... -
Page 21: Modes For Expression Pedals
This mode lets you sent the velocity (value 3) of MIDI Messages using the position of the pedal. This might be useful if you have a keyboard for example that doesn’t have velocity sensitive keys. You could effectively use the expression pedal to encode the velocity of the notes. MIDI Expression Manual page 21 / 31... -
Page 22: Midi Activity Monitor
MIDI Activity Monitor For MIDI Expression iO devices, a MIDI Activity Monitor gives you feedback about how MIDI is entering and leaving your device. MIDI Activity Monitor The LED will light green indicating the presence of ActiveSensing MIDI messages, and red for all other messages. -
Page 23: Snapshot Manager
Snapshot Manager The Snapshot Manager lets you save and load entire snapshots of a MIDI Expression device’s internal memory to local storage. These snapshots can be used to quickly swap between different configurations of the device, to create a backup of your settings, or to copy the settings from one device to another. -

Page 25: Using Presets
Toggling between activating and deactivating an input effectively lets you swap between two configurations for that input. Using presets Taking advantage of your host sequencer's preset system, you can load and save settings for any number of MIDI Expressions with a single mouse click.

Page 26: Ios Control Application
See below for details about the different ways you can connect your devices. Camera Connection Kit Using the Apple Camera Connection kit, you can connect a MIDI Expression directly to your iOS device. Using a USB hub is also supported, but if you plan to connect more than 2 MIDI Expression devices, it will likely need to be a powered hub. -

9. Click on the Connect button. That's it. The Control Application should automatically find and connect to your MIDI Expression. You'll need to create and connect to a different session for each MIDI Expression device you want to connect to over the network. -
Page 28: Updating The Firmware
(A) Changing Colors If you have more than one MIDI Expression of the same color connected to the same computer, you might want to change the ‘color’ of one of the devices in order to change the name of its MIDI port to prevent your host sequencer and yourself from getting the devices mixed up. -
Page 29: Restoring The Control Interface
MacOS or PC version of the Control Application. Restoring the Control Interface If you have put your MIDI Expression into the ‘MIDI’ only setup, you can easily restore the Control Interface using the Control Application. When you plug-in your device and start the Control Application, any devices that are in the MIDI only setup can have their Control Interfaces restored by clicking on the ‘Restore Control Interlaces’... -
