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.
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
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).
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
There are three options for controlling the Tap/Freeze function by Control Change (CC) MIDI messages:
|Default CC number||Function||Values|
64 - 127: Press
Suitable for full control of both Tap tempo and Freeze function by a computer or by any MIDI controller that can send CC commands.
Any value (0 - 127): Press immediately
Suitable for controlling Tap tempo by a computer or by any MIDI footswitch controller that can send CC commands.
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.
