Testing DIY triggers through a TD-20 but going to use a Trigger IO...??

[bakerboy]

I have access to a TD-20 module (from our church) that I can use to test my DIY triggers as I get them built. But will the piezo wiring to the jacks be compatible with both a TD-20 and with the Alesis Trigger IO? Because I'll ultimately be using the Trigger IO going into my computer and not the TD-20.

Or, I may want to one day bring my DIY kit up to the church and just plug into the TD-20 instead of using the Roland pads.

Does the piezo/jack wiring matter going from one to the other ??

Shouldnt matter as long as you selet PP in the setup on the IO.
All inputs on the IO are dual, so single or dual shouldnt matter.

The TD-20 dual inputs I think require a keith raper circuit - with the 100 ohm resister on the 'rim' input. The IO doesn't need this. I use a standard stereo to dual (tip/ring) splitters to get 2 single input pads to a dual input on the IO. It is my understanding that this WON'T work on a TD-20. If that is true, then there is a difference. Any reason you don't have the IO? it's pretty cheap. And, I've heard some issues with Roland pads working on the IO. If you test your pads on the TD-20 and get them to work, it might be problematic. I would really suggest getting an IO and testing it on the hardware you are going to use.

If it were the other way around, cost is a factor, but the IO is pretty affordable.
