TD-12 Channel 8 Rim doesn't trigger

[Larrio]

Hello all,

I just recently got some new pads and finally put one into channel 8 (Crash 2) on my TD-12. To my surprise, I get only the "head" sound whether I hit the head or rim. The rim light never lights up. I've tried it with a few pads and cables, and I keep getting the same thing. I opened up the brain and everything seems to be in order, though I noticed the channel 8 input doesn't have a chip whereas each other input has a chip right by it.

Is there no rim triggering for this channel?

I've noticed the same thing on the kick drum (channel 1), but I just assumed the kick would only have a head trigger.

Is my module defective or is this normal?

Thanks!

You should be able to trigger the rim of input 8 (Crash 2) and input 1 (Kick) with a dual zone pad, but the trigger type does have to be set to a dual model at TRIGGER, BANK.

What make/model of pad are you connecting?

Hmm.... Yes, I've connected my cy-14c, pd 105s and a pd 125. None of them triggered the rim sound for either the kick or crash 2 inputs. I get the head sound whether I hit the rim or head. The rim light never lights up. Whatever trigger I hook up, I make sure to switch the input bank to match the trigger model number. Is there something I'm missing?

I truly appreciate any help.

Hi Larrio, I had a terrible time getting my CY-8 to work, if you hit any other drum and the cy-8 at the same time then the cy-8 wouldn't trigger, I read here about "groups" so I hunted it out and put the cy-8 to group2 (everything else is group 1) and it now works like a bought one. It does make a difference if you have the wrong pad/cymbal selected in the module as well, it's quieter/louder until it's correctly set.

(I LOVE THE ABILITY TO EDIT STUFF AFTER THE FACT!!!!) After I wrote this, I started to doubt myself since you are getting a triggered response on both rim and head, but WTH....

Might also want to make sure that is a TRS (stereo) cable instead of a mono. When you are hitting the rim, you might be getting cross talk showing up on the head which appears like you are getting the head sound when you hit the rim.

[Larrio]

Yeah, I have TRS cables and there is no cross talk on for that channel.

So, canh folks here confirm that they can get head and rim sounds on channel one and channel 8 on a TD-12 using a dual trigger pad?

Thanks,
Larry

Are you sure you have the cables pushed all the way into the inputs? They can be very stiff if they haven't been used before.


Bruce

[Larrio]

Yes, the cable is pushed in completely on both ends and I've tried multiple cables. The head and rim both have sounds assigned to them, and they're both turned up in the mixer.

[BarT]

Only the CY-14C would trigger the rim of the Crash 2 or Kick inputs, as they're both piezo-switch inputs only. The PD-105 or PD-125 would not trigger the rim of those inputs on any module. So perhaps it's really the CY-14C which is defective?

If you have other CY cymbals, try their rims in those two inputs.

Does the CY-14C rim work in Crash 1?


Bruce

[Larrio]

Interesting, I thought all the pd pads worked off of two piezos. What exactly do you mean by piezo switch inputs only? Can you show me where this info is from? I don't see anything about it in the manual.

Anyhow, the CY-14C I have works fine in channel 7 (Crash 1). It gives me the head and rim sound very precisely. I haven't tried it in the kick input. When plugged into channel 8, I again get the head sound on both the bow and the edge.

I'll give it a shot in channel 1.

[BarT]

Most mesh pads have two piezos, but rubber pads only have one.

There's a table at the bottom right of Page 44 in the TD-12 manual which shows that a Dual Trigger Mesh Pad can only be used with the snare, tom and aux inputs.

Roland cymbals and rubber pads have one piezo plus a ribbon switch on the edge, and should work for head and rim in any input.

[Larrio]

Aha!

Thank you, Bruce.

Now I get it. I had looked at that chart before but it didn't make full sense until now.

I'll try my cy-14c in channels 1 and 8 again and see if I can get two sounds out of them.

I'd really like to use these inputs to their fullest.

For example, I've got a KD-120 kick trigger hooked into channel 1. If I were to split that input, what could I plug in to share it and trigger the rim sound for that input? I assume I could use a stereo male to two female mono splitter?

As for channel 8, I guess I'll have to look into another cymbal or perhaps a pd-7 or 8 would work?

Thanks again for working this out with me. I'll update this once I try some things.

So, can folks here confirm that they can get head and rim sounds on channel one and channel 8 on a TD-12 using a dual trigger pad?

Not sure about the kick input, but I do have a CY-14C plugged into input 8 on my TD-12 and it does trigger BOTH the head and the rim sounds.

-SD-

[Larrio]

Thanks Silicon,

Any chance you could try that CY14C on channel one and see if you still get both sounds? You could use a different trigger bank and set channel 1 to a CY14C so you don't lose your normal settings.

If you feel like trying the same inputs with mesh or other pads, that would be pretty neat, too. Then, we'd know for sure what is compatible with these inputs, and I could confirm whether or not my module is faulty.

For example, I've got a KD-120 kick trigger hooked into channel 1. If I were to split that input, what could I plug in to share it and trigger the rim sound for that input? I assume I could use a stereo male to two female mono splitter?

No. The only reliable way to split the kick input is Building Keith Raper's Circuit (because it's a piezo/rim-switch input which is not designed to handle a second piezo).
