  • Multiple Piezo per pad

    Hi - This may be a stupid question, but in general, can I connect several piezo sensors per pad and connect them in Parallel? Thanks, IDB

    well,

    i was talking about this a while back but we were talking about having multiple peizos in the pad and then only certain peizos triggering depending on how hard we hit the pad. so therefore it could be a tom or something at a normal hit and when its being emphasized one of the other peizos has a different sound to it. this is achived by midi.

    im not sure what you mean by parallel and i cant help you with wiring diagrams or anything cause i havent done it yet but lets hope someone else can help you.

      Yes, there are some builders in the DIY that put 3 or 4 piezos around the drum shell to better pick up the Rim

      What is it that you are trying to achieve?

      I use just use one and tape it in like this:


      also see my albums listd below

      "atomburst" - parallel connection will have all the black wires tied together and all the red wires tied together. if you drew a stick picture of a ladder and then imagined each rung of the ladder as a piezo with it's red wire connected to the left side of the ladder and the black wire connected to the right side of the ladder you would be looking at a schematic of a parallel circuit connection. Also like when you help jump start your buddies car with your car's battery... you hook red to red and blk (ground) to blk. the car batteries are connected in parallel

      now for a series connection (not what we are wanting to do in this case...hmmm- I wonder how that would work???) one red lead of one piezo would connect to one black lead of the next ..on down the line. sort of like a line of children holding hands - each child is a piezo and are linked in series. Another example of a series connection: one of those Mag Lite flashlights that holds 3 or 4 batteries - the batteries are all stacked (in series) on top of each other. in series the voltage of the batteries add up so two 1.5 volt batteries, in series, produce 3 volts.

        Interesting idea.. I was thinking of something similar for triggering all the different backing parts in my originals, but couldn't think of a practical way to eliminate the xtalk.. I'll be very interested to hear what the "pro's" think about this...
        "Today young men on acid realised that all matter is purely energy condensed to a slow vibration; That we are all of one consciousness experiencing itself subjectively; There's no such thing as death, life is only a dream and we're the imagination of ourselves.. Here's Tom with the weather"...

        TD-20 + TMC-6 + VF-1 + Gen16's = Not enough inputs.

          I used to have a 10" Dauz pad that used 3 piezos to even out the sensitivity across the playing surface. All the red leads went to one pole of the jack, all the black went to the other. I think this is what is meant by parallel wiring. If so, then yes, you can wire piezos in parallel.
          Id rather be told the ugly truth than handed a pretty lie.

            Yep - that's a parallel connection

              Parallel connections seem like it would be fine, but a series connection probably not so much. I think the impedance of the piezo would kill the voltage coming in, not to mention phase cancellation issues. Again, I want my scope back...

                i follow the rule of thumb thumb of using stereo or mono leads you get one piezo for evey black line on your lead if you want more piezos on one pad then put more jacks on it and get more cables....one thing that does work is membrane switching being daisy chained for diy that means you could get a choke from a dual zone pad by making a switch with a piezo bieng grounded or hot on each side and when you squeeze making contact you make a short circut and stops everything...it's like hooking up speakers.

                and unless your super good at diying some membrane swich and samall pcb and a micro controller you could diy a cy12 c/r clone
                with membranes for bell edge and choke and only one piezo for bow.
                aperently when you hit the edge or bell the one pizo registers how loud to play that strike
