Mega-pad or Mega-Zen Clone

I'm building a Zen drum clone with 32 pads.
My question is since I'm only going to be using 4 jacks a floor trigger pad with a kick,hihat,snare, and a tamborine.
How do get my other 28 inputs/piezo's?
I'm a percussionist so this won't be a drum module.
Is it like dual inputs or what?
Will start posting pics soon.
Peace!

If I'm understanding you correctly, you will only need two stereo jacks or four mono jacks to the outside of the zen drum. The rest of the piezos could be hard wired inside the zen drum without using a jack, or they could all be wired to an internal connector for easy removal of the circuit board. There is no need for jacks on the inside ones, they can be wired directly. A 40 wire IDE cable works for this.

Well thats part of it, I plan to hardwire the piezo like you said.
But at 2 wire each I'll be coming up a bit short of 32 inputs.
Or is it like dual zones per piezo.
I was planning one sample per pad.
Sample:
1. Conga
2. Quinto
3. Tumba
4. Djembe
5. High Timbale
6. Low Timbale
7. Bell
8. Jam Block and so forth up to 32 instruments.

You do take in account that one input is used by a HH pedal, don't you? The rest 31 inputs you can use for piezos.

I guess what I'm trying to get at is do I solder one wire to both the leads coming off the piezo.
Or is it a ide wire for each lead coming of the piezo

You solder one wire of the piezo to a signal wire and another wire of the piezo to the ground(GND).

Sadly on my part alone still I am not understanding.
Are the any diagrams for this.
I understand using the 40 pin ide cable but at 2 wire per piezo (17 inputs) I'm coming up a bit short of 32 inputs.
Do I use the jacks boards for this and how do I this.
Blue bass if you're around your help would be grately appreciated.

It has 32 inputs - 1 for a HH pedal and 31 for pad inputs. All inputs can be either used individually or, except the kick, can be joined into dual/triple zone pads/cymbals thus using stereo jacks and as a result two/three signal wires per a pad (not per input input!). The two wires per piezo are a signal wire and a ground wire. For 32 inputs it is 32 signal wires and 32 ground wires.

All 32 piezo grounds (rings on jacks) are connected together to GND pin (i think its pin 40) on board connector
