If you have the swell shoes plugged into the pedalboard, you need to configure them via the pedalboard. See pg. 8 in the pedalboard manual. 

Shoes are considered "Analog Inputs". You need to set the output of the shoes to the appropriate channel, AND message before you will see any output data. See the output to send a volume control change. (control message 07)

If you have the shoes plugged into the keyboards themselves, then you can use the CMK Config software to configure them. Keep in mind that one input is for Ahlborn Crescendos only and the other is configurable by the software.

If you are using a PC you can confirm the correct the output from your MIDI gear by installing MIDI Medic from the Classic Organ Works CD.

If you are using a Mac, you can download MIDI Monitor from the internet. It is free and does mostly the same things.

If you get the correct data coming out of the MIDI gear (confirmed by MIDI medic) and then it doesn't work in Hauptwerk, then it is a Hauptwerk config issue.


Here are some Typical Swell Shoe sequences


After Pressing the programming push-button you have about 10-15 seconds to complete each sequence. 

You need to press the push-button to start programming each sequence as well. 

You will not see any MIDI data from any analog input until both the channel and the control message sequences have been completed for that analog input.


Analog 0 (closest to the black stripe)

F#1 F#2 B1 A#2 Channel 7 (This defaults to Hauptwerk's Crescendo pedal)

F#1 D#2 E1 A#2 MIDI Volume Control (07)


Analog 1

G#1 F#2 E1 A#2 Channel 3 (This defaults to Hauptwerk's Swell pedal)

G#1 D#2 E1 A#2 MIDI Volume Control (07)


Analog 2

A#1 F#2 F1 A#2 Channel 4 (This defaults to Hauptwerk's Choir pedal)

A#1 D#2 E1 A#2 MIDI Volume Control (07)


In Hauptwerk, the swell shoe hardware settings are configured in General Setting>Continuous Control MIDI inputs. However, using the above settings your on-screen swell shoes should be automatically connected your physical swell shoes.

For the pedalboard, I generally recommend the MKSC4a. Especially if you have magnets on the pedal keys already. This is the scanner we use in our pedalboards and we have a pedalboard switch kit to make it easy for those with the magnets. It has 3 swell shoe inputs built into it. If you have our keyboards, the MKSC4a is not so crucial since each one of the keyboards also has 1 swell shoe input in the back. The MKSC1a is much easier to wire up than the MKSC4a so if you have the keyboards 


For pedalboards we can provide you two types of scanners which will convert the key presses into MIDI data for your MIDI interface. If you 8 x 8 matrix wire the pedalboard, you can use our MKSC4a product . If you parallel wire it, which means 1 wire per key with a +12V common wire (A.K.A. a contact rail), you can use our MKSC1a board. 


The difference between parallel and matrix wiring is this: 

Parallel wiring uses a single power source (usually +12v) connected to all the keys and one - wire coming from each key. This results in 62 wires from a 61 note keyboard. 

Matrix wiring groups the keys into an 8 x 8 matrix. Think of it like a checker board with 8 squares on each side. To find the address of any square, there is a row and a column that is unique to that square. That is how 8 x 8 matrixing works. The result gives you 16 wires out (8 for each side of the matrix) instead of 62. 

It sounds like you will be using a parallel scanner. You will need one scanner for each keyboard or pedalboard.


Since the pedalboard will only use up to 32 of the inputs, you can use the leftover inputs for pistons, tabs or toe studs if you are going to use Hauptwerk.

First thing to do is to loosen the big screw on the bottom clamp so that the clamp is really loose. Then you slip the channel over the lip on the back of the pedalboard (the channel is lined with red felt) and slide the clamp underneath the pedalboard. Move the shoe into place and tighten up the screw to secure the shoe in its place.


The key is to really loosen that bottom clamp. That eliminates most of your problems.

Sounds like you need to save the configuration into the memory of the keyboards.


After you do all your channel and piston assignments, click on the Lightning bolt icon at the top of the screen. That will load the config into the keyboard memory. Note that to do this you need the MIDI in and outs plugged in to the stack and connected to the computer.

After you do all your channel and piston assignments, click on the Lightning bolt icon at the top of the screen. That will load the config into the keyboard memory. Note that to do this you need the MIDI in and outs plugged in to the stack and connected to the computer.


Once you have downloaded the config into the memory of the keyboards,if the lights are still blinking, unplug the midi out from the computer. Something in your computer is sending MIDI signals whether you are playing or not. 

It should quit freaking out if you unplug the MIDI out. Modules and Hauptwerk only need MIDI in.

If you unplug the computer's MIDI out and boot everything up again, you should be able to plug it in again with no problems. One of the windows drivers probably had a problem with the config process.
