How to wire drum trigger properly for yamaha dtx pro

[dani0512]

Hi, i'm new to electronic drum.

I have been looking on the internet for a month about how to convert my acoustic drum to e drum. I recently buy dtx pro. For trigger i used 4 pcs piezo. 3 piezo in series for the head, and 1 piezo for the rim. All is 27mm in size. I connect ceramic part of the first piezo to the tip, and brass part of the 3rd piezo to sleeve. For the rim piezo, i connect the ceramic part to the ring, and the brass part to sleeve. When i connect it to dtx pro module, it only make head sound, there is no rim sound. When i hit the rim it make head sound like when the head is hit.

Please advice, is there any mistake i made on wiring the piezo? Or there is any setting on the dtx module?

What socket on the module? (have you tried others)
What cable connecting pad to module? (should be TRS)
What pad-type have you set on the module?
What input-mode have you set?

* because it is still a trial, i solder the wire directly to the cable. Should i solder the trigger's wire to trs socket?
* i'm using trs cable

I do nothing on pad type setting & input mode. Please advice what setting should i do with pad type and input mode?
