Two triggers into One port?

[jackeen]

I tip my hat to you

thanks


-------------------

Job done took ten minutes

after looking at the drawing again its actually just a 100k resistor between the 2 tips

Ive modified the drawing slightly including the 100k ohm resister. I am right in saying that the 2 jacks can be either stereo or mono jacks ??

Hey Jackeen ... I liked your 1st drawing better ... cept the 100Kohm change... I wanna see some people try this adptr out ... I think it is gonna be a winner in the Y adapter dept.... J

That would be totally cool as I am 1 input short for the drums I am planning on my TD-12. I will have a splash and a china and only 1 input (the Ride Edge input) left if all goes as planned. If I can split that input for the splash and china, that would be awesome.

Of course, I may just go upgrade to a TD-20 anyway. The expansion that is coming is supposed to be mind blowing.

Thanks!

Edit.... This Splitter is specifically designed for dual piezo inputs the results are inconsistent with other inputs...

Ray... As Chris said though this was designed with the Aux. or tom ... dual piezo type inputs in mind... could be just a fluke that it worked on all I tested... but I can tell you for sure though... If you had 2 single zone cymbals and wanted to use one input... it can be done!.... so inputs can be split. I'm assuming here, that the TD-12 will work similar.... I Don't have that module.... J

Cool. Thanks Jman.

I actually think that I am going to build a splitter box.

Two mono jacks, one stereo jack, a 100K resistor; all wired as the first diagram indicated.

I have all the parts already and I have plenty of mono cables, so all I'll need is a stero cable and I'm ready to split inputs.

Ok.. just to please Jman here's both versions, which are identical wiring.

Tried it today ... worked spot one .. Now I can buy loads more stuff to hit !!!

Thanks to Hiroshi for the design

If I ever get to the good 'ol U S of A I'll buy you a bud or 20

Glad you got it working, Jackeen. Now you can continue your guilty pleasure, i.e. "pad acquisition syndrome", AKA J-Man's Disease.

Glad you got it workin jackeen... nice pic-graphs... makes my drawings look like Tic-Tac-Toe... in the dirt.... and great design Chris... glad we can get there by using an adapter instead of having to do pad mods!!! J

[Pimenta]

You guys suck !!! I will have to go after a resistor tomorrow .. have plenty of "splitters" to break ....wife not around .. plenty of time ... so here I go ....

Great... now potentially how many single-trigger cymbals could I squeeze in... hmmm...

[JmanWord]

The one I built... I started with 2 mono 1/4 female in-line jacks... they are easy to work with cause they are made to be soldered to... and 1 Stereo Male plug... and some speaker wire. Radio Shack is more pricey though.....

So if you already have some audio insert cables you could make this...

Sure, you could make that, but it wouldn't work: it's not an equivalent circuit. The resistors in the wrong place.

PS forgot to mention that one reason I like using a potentiometer is you can set it to zero (closed), and the adapter then works like a regular Shack Adapter to give velocity switching on the pads (or just one pad, if you combine the right type of pads). Most people would probably be content with the dual-piezo pad split, so go with a 100k ohm if that's all you want/need.

The resistor is in the exact same place. The 2 tips (on right) connect to tip and ring of the trs connector (on left). So, if the resistor is put between the tip and ring, it effectively ties the two tips together.

[hiroshi]

OK, I see what you're doing now. I was looking at it backwards.

Funny how everyone draws and sees this circuit differently.

Here's the way I think of it, since it corresponds more or less to the physical layout you'd have with an external adapter box:



The circles on the left are the piezos (signal generators), and the module trigger input is on the right side of the page.

I have used the diagrams and have managed to split the inputs as everyone else has.

I am interested mostly in doing this to add more cymbal triggers on the aux's.

My problem or observation is that the cymbal that is on the rim side of things does not trigger all the time or when hit softly. In general, the triggers do not happen when you strike the edge but the top of the cymbal only. When you hit the edge hard enough it will trigger but not consistently on the rim side of the split.

I have adjusted threshold etc. I have tried different pads for the trigger setting and used cymbal or pad in the mount setting.

Is there something else that I may be doing wrong or have set up wrong? Could my 100k resistor be bad? Or is that just the nature of splitting the input?

Thanks in advance for any input you may have.
