Stand Alone Bass Pedals

[beautrager]

Ha Ha! look what I got up to today. Converted an LSI into stand alone bass pedals. Still needs some finishing touches of course but other than that it works just fine.

It's pretty hilarious. Only has one tone and I had to keep all but one circuit board to keep it working.

I'd like to do another one up and maybe see if I could link in some of the tones from the removed keyboards and maybe mount the drum machine on there too. What do you think?

Looks cool! Why not MIDI it? Then you can have all sorts of tones.

This involved no soldering or purchasing of anything other than the organ itself and has always been something I've wanted to try. I also plan on using this below my Yamaha CP-33. So keeping it all simple analog will be a part of the over all sound of the two instruments together.

I do have future plans of learning how to do up midi pedals. I've got a spare set I can work with. Then if that's successful I'll move to doing a 25 note pedal board. I'm not super familiar with Midi. Do I need to hook it to my laptop or can tones be stored in other devices?

Super Cool project!! I myself had just had the same idea recently...In my case i want a stand-alone pedal unit to replace the standard pedals on my chopped Hammond L100 ....How does this hook up to an amp?..And by any chance do you have some construction photos?..

I think this is a cool idea, especially when you look at the cost of commercial pedal boards. Combining the pedals from two organs would be a great way of making a 25-note board, too.

Midi is just a digital signal that says "this key was pressed" (or released). The analog note itself is then generated in your laptop, or most any other device that has a midi input.

To midify a pedal board is very easy, you just need a tiny circuit board that has a single processor on it, and some diodes. These circuit boards are readily available commercially from a variety of sources, or of course you can make your own.

Hooks up via 1/4 Jack either the headphone jack or one that I attached to the wires I detached from the speaker. Great thing about this LSI (and I imagine most) was I found on one of the circuit boards a "Main Level" dial. So I just turned that down a bit and avoided having to do any "padding down"

I don't have any construction photos but I could take some that show what exactly I did. Which honestly wasn't that much. I think If I got more into it I could make the thing a little smaller. Would just involve a little circuit board Feng Shui.

I agree, it looks cool ! A bit cumbersome to travel with regularly, but built very solidly. Are all the controls under the cover ? More photos please !

[beautrager]

Some Photos for ya.


under the hood

One of two 1/4 jacks. This one is the headphone jack (yet to be mounted)

On the right is the power supply board which had to be brought up from the cabinet of the organ and mounted there as well as the transformer. on the left is a big mess of cords I gotta deal with some of which are from the volume pedals which I was surprised the organ works without it hooked up.

board on the left is the main controls and one on the right is the ryhthm (had to keep the rythm one even though I didn't want to.) have yet to mount either as you can see.

for now I have "pedals Sustain" and "pedal accent" locked on which I did by simply putting hooking the springy contact under the solid one. I'd like to make a switch for "pedal sustain"

The day I came to terms with the fact I was an organist was the day I accepted "cumbersome" into my life. I've been lugging around a Hammond console or a YC-45D (sometimes both) since that day. Anything even remotely smaller seems like a breeze.

The most readily available MIDI sound source would be a $99 WalMart keyboard, particularly an older one via CraigsList. A module (which is a keyboard with out keys, i.e. sounds only) is even better but few have been made in the last decade. As described before, the MIDI system just tells the sound source what note to play and in many cases how loud to play it (not in this example), and what sound to play.

These pics didn't show up. At least not to my computer.

a) I have been buying MIDI Home Organs when they are cheap and then ripping them apart to build consoles that include MIDI bass-pedals

b) I found a set of Roland PK-7 pedals that are pretty cool.

so now I am into stacking my bass pedals the same way one would stack keyboards. Who knew my feet had so much to say ?

Now I can see 'em. LOVE the stop tab modern art on the door! That's clever recycling.

Great project...I'm keeping my eyes peeled on CL from now on..Next free LSI organ is coming home with me!!!!!!!!!!!! :-)
