To begin using Iridium with an external MIDI device, connect the MIDI out jack from a pedal, controller, or computer interface to the EXP jack on Iridium. The following devices can be used to send MIDI messages to Iridium:
Set EXP jack to DIGITAL Mode
Once you have connected Iridium to a MIDI source, you must set the EXP jack to DIGITAL mode.
Set MIDI Channel
Next, you will need to select a MIDI channel to communicate with Iridium. Iridium is set to MIDI channel 1 by default.
The MIDI Output mode must be set to determine what kind of MIDI data is sent out by Iridium. ***NOTE: If you are only sending MIDI data to Iridium or if you are using the Strymon MIDI EXP cable, the MIDI Output mode must be set to OFF.***
With the EXP jack set to DIGITAL mode, the currently loaded settings can be saved to any of Iridium’s 300 preset locations at any time.
Iridium contains 300 preset locations, numbered sequentially from 0-299. Because MIDI Program Change messages have a maximum number of 128 (0-127) the presets are grouped into three MIDI patch banks:
Iridium always powers up in MIDI Patch Bank 0, so if you plan to stay within the first 127 presets, simply send a standard MIDI Program Change message to load a preset.
If you will be using MIDI Banks 1 and/or 2, it is advisable to send a standard MIDI Bank Change message (MIDI CC# 0 with a value equal to the MIDI Bank#) before each MIDI Program Change.
Selecting bank 0, patch 127 will put Iridium into Manual mode. In this mode, the pedal will be set to the current knob and switch settings. No preset data can be stored at this preset location.
