Can any clever person please explain something about how our Jobeky HH controller works?
Wot aspect is it of the device that tells the brain/module (TD-3 in our case) to make the "chick" sound?
Ours does the chick when you tread all the way down on the pedal (as if closing real hats completely and holding them closed) but usually emits another as you take your foot off, for a sort of unwanted double "chick".
Beginning to investigate, I removed the cymbal pad, and unplugged its lead from the module, only to find that it still goes "chick" when you press down the pedal - even though there's no cymbal on it.
How does that work then? I thought the controller just had a variable resistor inside to tell the module whether the required sound was open, closed or "halfway".
How does the potentiometer say to the module "go chick" and is it anything to do with that bit having a TRS (aka stereo) plug and cable?
As ever, all contributions gratefully received.
Ta! |

| Modules give the 'chick' sound at a chosen value of resistance change. The volume of the 'chick' sound comes from the speed of change of the resistance. This is how all variable hihat controllers work. The hihat pad ONLY send stick trigger info - everything else is determined from the resistance change in the controller. |

| Ahh! Thanks flurbs. So is there any reason for the TRS lead, and any idea why our controller appears to be "chick"ing again when the resistance changes back the other way? Cheers! |

That would depend on the exact wiring but resistance only needs two terminals so TRS isn't a necessity.

That would be a question for Jobeky.

| Hi there im having a slightly different problem with mine. when i take my foot off the pedal im very often getting an involuntary splash sound. I to had taken the top hi hat of the stand and when i pushed the silver spring mechanism up and down it still does it. It is more than slightly annoying esp when doing a lot of foot work. Colin knows about the problem with mine and is currently working on a solution, but i was wondering if anyone is having similar issues? The rest of the stealth kit is blob on tho and is an absolute joy to play. Mines hooked up to a td9 by the way. |

Update :
Sent controller off to Col.
Got it back fixed - excellent!
Only troub is, it won't do "in between" sounds any more, which it did before the repair. Only open or closed (TD-3 brain BTW.)
What's that all about then?? |

Ah, well now, you see ... we've had two pre-loved TD-3 modules on our Jobeky classic in the time we've owned it. The first (and older) which we subsequently sold, did not appear to do do in-between sounds, but then I didn't expect it to. However (and much to my surprise) the current one definitely does. Or at least it did, both with the Jobeky Truetime and, according to a mate who borrowed the module for a night, with a Yamaha pedal (HH65 I think.)
I mentioned this to Col when on the phone about our controller problem, and he said that he had not owned a TD-3 recently, but he confirmed that he had heard of this phenomenon, and said it was possibly a firmware thing.
Anyone shed any light? And I promise, promise, promise, it really did make all the "continuous" sounds before the repair - we weren't imagining it. Honest! |

Cheers Giffo.
I'm just wondering what it was about the repair that removed the ability to trigger variable sounds?
Does anyone know what value the potentiometer in the Roland FD pedals would be? |
