Hauptwerk Organ Pedals Complete

After a loooong hiatus I finally got to start working on actually rewiring my pedals!! Marvin was busy and I didn’t wanna go ahead without him in case I make a colossal mess of everything. Plus he’s the one with the soldering iron.

We started working around 7:30pm and didn’t finish till close to 2am!! :p

Also, if this stuff interests you, you can help by reposting this and/or visiting my indiegogo at http://igg.me/at/buildahauptwerkorgan and making a small contribution. Thanks in advance!

YOU NEED:
1. Your pedalboard
2. A friend
3. Screw drivers
4. Cable ties
5. Emory cloth
6. Soft bristled toothbrush
7. Pliers
8. Soldering iron & solder
9. Midi encoder (I’m using the pedal and swell encoder from DTS), with Molex connectors
10. Small screws to screw encoder to board
11. The new wires to connect to the encoder (circuit) board (Mr. Max Mayse made mine for me, thanks! Not sure how you make them…)
12. Main/common wire (mine’s yellow, it’ll be soldered to the wire that runs through to all the contact blocks and basically allows power to run through them when you plug it in to a power source)
13. Midi adaptor (midi out to USB)
14. Power supply adaptor thingy

BEFORE:

AFTER:

It’s almost like we knew exactly what we’re doing! (We didn’t)

1. Turn pedalboard over, with #1 (low c) on the left and #32 (G) on the right.

2. Took the contact rail off carefully, minding all the contact wires, and put it on top of the board; Taking only the outer two screws out for each side so it doesn’t fall onto the board and mess all the contact wires up even if we let go.

3. Snipping the old wires off. All of them.

Snipped wires: 

4. Took the cover off the contact rail to reveal all the wires underneath: 

Used an old soft bristle toothbrush to clean off the dust really carefully. (Marvin, “I feel like an archeologist!”)

5. Snip. Snip. Snip!
Snipping the twine-like stuff holding the wires to the rail:

the old wires:

Snipping the wires close to where it was soldered to the block:

No more wires!
6. Clean the contact wires and the metal plates with an Emory cloth:

Nice and shiny! You don’t need to clean the entire metal plate, just the top part that would be making contact with the contact wires.

7. Place the rail back where it was originally, but don’t put the screws back in yet; will need to turn it over again to solder the wires. Staple the bunch of cables to the side of the pedalboard. (with a staple gun, not your desk stapler…)Pulling out the cables out from the little grey tubing. Fun!

They’re color coded!!!

8. Thread each wire through each hole for its corresponding note. Snip off excess but make sure there’s enough to reach the solder point on the contact block.

9. Cable tie the wires through each hole. Make it all nice and neat!! I used pink and black cable ties and alternated the colors, looks cool!

10. Snip off ends of the cable ties parts sticking out:

11. THE SOLDERING IRON DUN DUN DUN!!! (Set to 800 F°)

12. Strip the ends of each wire to expose the wire inside. Wrap it around the little tiny metal pole for each contact block.

13. Take soldering iron out of the station, touch the tippy point of the iron to the pole that has the wire wrapped around. Melt the solder over it, make sure it’s sealed and connected. Repeat 32 times for all the notes haha.

Soldering the last one, you can see how excited I am tehee!

14. Two wires from each contact is connected to a bus wire or ‘common’ for all the keys. Solder the main/common (yellow) wire to anywhere on that common wire; pick a point between 2 contact blocks. We chose the spot that the original common wire was soldered to, close to where we want to mount the midi circuit board.

common wire: the long silverish one there in the pic.

15. Screw the cover back over the contacts and put the rail back where it was, screw everything back in.

ALMOST DONE!!!

16. Mount the circuit board to the top of the pedals.

17. Stick the common wire into the GND (ground) on midi circuit board, turn the little screw on top to hold the wire in place.

18. Power supply: stick the positive end into PLUS and the negative into the other hole for GND. Thanks again, Mr. Mayse for the power supply, making the knot in the positive and marking it with a sharpie!

19. Stick the molex connectors onto the circuit board!! 

20. Connect MIDI to USB adaptor to the circuit board 

ALL DONE!!!!

Just turn the pedal back over. Plug the power in. Connect the pedals to your computer and run HAUPTWERK! It should pick up that you have pedals plugged in, and you can then configure it to recognize note and highest. AND PLAY!!!

I thought I didn’t solder the last 3 notes right but turns out St. Ann’s which was the organ I was running didn’t have sound samples for those notes.

SOO HAPPY!!!! *SQUEAL!!!*
