Drum Pads



Four drum pads ready to go.

All made of old mate­r­ial found in the Alt/Lab instal­la­tions, and a very spe­cial big thankxxx for Mónica who brought the cas­ings (we are going back to that in a moment) for the drum pads.

So the idea was to make drum pads that we could hook up to a sound card(or what­ever) and them make sweet music, this is a very nice com­bi­na­tion between piezo­elec­tric com­po­nents and a few lay­ers of some absorbent sound  mate­r­ial like rub­ber or cork foil (that’s what we use because there was noth­ing more) and a piece of alu­minum foil for a greater drum area .

We use an old can (20l) of paint, four piezo­elec­tric found in elec­tronic junk like old modems and old tele­phones, wire for con­nect­ing the piezos, cork foil for insu­la­tion the drum pad area and Mónica sup­ply the cas­ings (square rub­ber cd´s stands), and glue for putting every­thing nice and tight .

First we cut a piece of the can (cir­cu­lar about 10cm radius)and we glued the piezo into it, then we drilled one hole into the rub­ber cas­ing for the wires to came out, them we cut two square cork foil parts (the first in the bot­tom of the cas­ing and the other for the top) a bit of glue and that’s it drum pads ready to rock.

Now we got some audio com­ing out of the pads but thats just bor­ing because its always the same and we want to go fur­ther like trans­form­ing audio into midi mes­sages, and we found the right tool for it, its called  “KTDrumTrig­ger” and he trans­forms the audio sig­nal into midi notes, we can use this midi notes inside a sequencer pro­gram to con­trol any kind of instru­ment (either VSTI or some other stuff), in our case we use the drum pads to con­trol “Bat­tery” and thats it instant fun.

There are some other links and some other ideas for drum pads. This “one“uses ardunio as a source for the imput sig­nal.
