MIDI Control for Electro Harmonix Cathedral Stereo Reverb

The Cathedral Stereo Reverb from Electro Harmonix is an excellent reverb guitar effect with infinite reverb („freeze“) and  tap tempo function. Unfortunately, it has not got any MIDI control.

MIDI Controller for Electro Harmonix Cathedral Stereo Reverb

Using our electronic kit it is possible to control the Cathedral by Program Change or Control Change MIDI command. The principle of operation is that the built-in MIDI controller electronically simulates turning and pressing the white control knob (encoder) and replaces an activity which would have to be carried out during the guitar playing. Instead, just by pressing a button on a MIDI footswitch controller, the Cathedral is automatically set to the preset corresponding to the number of Program Change/Control Change (1-8) or set to a sound corresponding to the momentary parameters of the black control knobs without preset (Program Change 9 or more or Control Change value 0 or 9 or more).

MIDI module for EHX Cathedral Stereo Reverb

This small electronic kit facilitates controlling the Cathedral using a foot MIDI controller or from a computer by DAW software. The module doesn't affect neither the original sound nor functionality. It works in parallel with the knob. Moreover, if you move the knob, the mod isn't lost and after receiving appropriate MIDI message it sets correct program regardless of the previously set program.

How it works

Tap controllers

There are three options for controlling the Tap/Freeze function by Control Change (CC) MIDI messages:

Default CC numberFunctionValues
CC#21 Momentary

64 - 127: Press
0 - 63: Release

Suitable for full control of both Tap tempo and Freeze function by a computer or by any MIDI controller that can send CC commands.

CC#22 Pulse

Any value (0 - 127): Press immediately
Release of the Tap switch is carried out after 10 miliseconds from receiving the CC.

Suitable for controlling Tap tempo by a computer or by any MIDI footswitch controller that can send CC commands.

CC#23 Toggle

Any value (0 - 127): Toggle the state of the switch: first CC carries out pressing, second CC carries out releasing of the footswitch. And so on: press, release ...

Suitable for controlling Freeze function by any MIDI footswitch controller that can send CC commands.

The CC numbers can be reprogrammed from default values to any other numbers (0 - 127) - see the next paragraph.
