Hi-hat crosstalk to snare (mostly rimshot)

Hello
Purchased DM6 USB kit few days back from authorized dealer, set it up.
All begun to work ok, except that there is obvious crosstalk from hi-hat to snare (triggers rimshot), it depends on the force the hi-hat is triggered (anything but very weak triggers snare).
This is very annoying and real mess affecting usability of the otherwise neat edrum set.
After the nigh spent searching through various forums it appears the common issue with DM6 since awhile back, too bad I did not do my homework before making the decision.
Upgraded the softwrae to v.06 from Alesis download section - didn't help either.

What to do now ? Is there nothing to do but return to the dealer and look elsewhere for a competitor ?

  • Hello Alex,

    Thanks for posting. I'd like to help! Let's try to reinitialize your module. Power it on, while holding the + and - buttons. This will restore the factory settings, erasing any recorded data or changed settings, including User Kits, the User Pattern, and any volume, metronome, or Voice settings, which will return to their defaults.

    If this doesn't work, log onto the DM6 product page here http://alesis.com/dm6 and update your firmware on the DM6 module.

  • Thanks a lot
    As I mentioned, I did software upgrade, that didnt help.
    The system is brand new other then updating software, no any user setup stored yet.

    • Hello Alex,

      Thanks for posting this about your crosstalk issue. This was great and useful information. Makes sense. I'm sure will help someone else in the future.

      As for your volume, have you adjusted your kits volume? To adjust the Kit's volume (which is different from the module's master volume level), press VOLUME to enter Volume Adjustment Mode. The Volume Indicator will light up and the LCD will display the Kit's current volume. Use VALUE +/- to adjust it. When you are finished, press KIT to re-enter Kit Selection Mode or press another button.

      You can also adjust your triggers volume. To adjust a trigger's volume (which is different from the Master or Kit volume levels), press VOLUME to enter Volume Adjustment Mode. The Volume Indicator will light up and the LCD will display the trigger's current volume. Use VALUE +/- to adjust it. When you are finished, press VOICE to re-enter Voice Selection Mode or press another button.
    • Well, snare was the only affected, neither toms, cymbals nor kick where apparently affected.
      I understand on DM6 there is no way to control trigger sensitivity on each piece separately

  • I’m disappointed
    I've got the same problem. The snare rim-shot is frequently triggered by vibration from the hi-hat. If I hit the wing-nut on top of the hi-hat it does it every time and hitting the supporting arm that the snare is attached to also causes it.

    I see there is some advice on adjusting the volume - I don't think that's going to help because I don't want to reduce the volume of the snare. As you say - I want to decrease the sensitivity of the trigger to stop the vibration activating it. I guess I could decrease the volume of the rim-shot but then I lose the option of playing that when I intend to.

    I've got 10 days to make a decision on whether I return the kit to the store. Any suggestions?

    Well, I'll save you the frustration
    There is nothing to do with volume of whatever, sensitivity (on DM6 there is no separate control over trigger's sensitivity as far as I'm aware of).
    The actual reason behind that is pure physics, in particular the nature of wave propagation (vibration or shock is mechanical wave) through the matter.
    The arm on which both the snare and the hi hat resides is effectively beam, i.e. one end of this is fixed, the other one is free (or at least has considerably more freedom). If you hit the arm at some point close to the fixed end, the vibration wave will propagate along the arm to both sides, however propagating towards the "free" end it will be amplified along its way. You would see the amplitude of the vibrations at the free end to be considerably larger then at any point closer to the fixed end. The longer will be the path from the source point to the free end, the more vibration amplitude will be gained.
    People often wondering looking through the window of the airplane noticing the end of the wing vibrating kind of bird wing...exactly the same physics. The wing is just a beam, fixed at the one end, free at the other so any force applied close to the fixed end will get amplified along the beam and manifests itself as much larger vibrations at the free end.

    Now lets get back to the ground..
    If you have your hi-hat clamp residing let's say in the middle of the arm, hitting on hi-hat will generate shock wave that is transmitted to the arm and begin to propagate along the arm. It is amplified more and more in amplitude until reached the free end of the arm, where snare is fixed. Hence snare will pick those gained shock wave and may respond to it as we both experienced.

    Here is the trick: re-position the snare and hi-hat clamps on the arm, basically swapping them in location. Have the snare clamp somewhere in the middle of the arm and the hi-hat clamp - at the "free" end of the arm. How hitting the hi-hat the shock wave has only the path to propagate towards the fixed end fo the arm which effectively attenuate the wave energy so only some small portion of hi-hat shock ware energy can be picked by snare clamp and most certainly the snare will not respond to that.

    Once I did that, that completely eliminated the issue (and saves for you the otherwise neat and affordable edrum set).

  • Awesome explanation! Thanks for that. But.. that means that the hi-hat is in front of the snare? Can you really play it comfortably that way?

  • Well, yes, technically the hi hat clamp resides in front of snare clamp on the arm, but by tweaking their positins on the rods you can achieve very usable playing position. Just apply some angle to the hi hat rod not to interfare with (actually above) snare trigger..and pull the snare as much as possible out on it's respective rod.
    Tweak them here and there, within few minutes you will find the setup that allows normal usability.
    Of course, the best way to resolve that would be a separate arm to fix the snare on...however it appears only the racks of higher level edrums (read..mich more expensive) offer that.
    I"ll try to upload an image that illustrates my approach..

  • I changed the setup last night and it has solved the problem. I have taken the hi-hat off the side arm and put it on the back rail to the left of the hi tom. The support comes almost horizontally but you can angle the hi-hat so that it sits flat. I think it's a better position as it allows me to position the snare wherever I want it on the side arm without worrying about squeezing it in beside the hi-hat. I need to adjust the crash cymbal position to keep it out of the way of the hi-hat but it's still easily within reach.

    Thanks for the suggestion Alex!

  • Great ! As long as it works for you go for it
    I have the hi hat at the very edge of the left arm and thesnare in the middle of that arm. The snare is pulled out aasmuch as possible on its rod towards me and the hi hat support leans heavily to the left so that the hi hat cymbal does not interfare with the snare

    Hi everyone!

    If you're having trouble with crosstalk on the DM6, check out our troubleshooting guide here:

    DM6 - Optimizing Performance and Minimizing Crosstalk

    The guide will walk you through a few common troubleshooting procedures, like updating the firmware, resetting the unit to factory settings and rearranging the pads and checking it's stability. The relationship between the pads are the biggest common factor for crosstalk problems, so often rearranging the pad's position on the rack arm and checking to ensure the clamps are secure can often resolve simple occurences of crosstalk.

    I hope this helps!

  • I’m frustrated
    This reply was created from a merged topic originally titled HI-HAT triggering wrong outputs.

    When I hit the hi-hat it also triggers snare and the kick. This does not happen regularly but when it happens I have no other choice to close the kit down. It really very irritating when this starts happening.
