  • TD-30 : how to hack VH hihats into a VH-13 and get extra smooth openings


    This trick works with the VH-12, maybe with the VH-11 as well?

    As it appears, appart from a sensor difference advertsied by Roland between the VH-12 and the VH-13 (but how is that a variable resistor could be faster than another?), the difference between the VH-12 and the VH-13 is resulting from a different interpretation in the module of the curve response of control change #4 (cc#4 responsible for the open to close variation). Maybe what Roland meant speaking of a faster speed in the sensor, is that the resistor has a more opened curve, allowing close positions between slightly opened to slightly closed, to be spanned over a larger portion of the resistor track. Not that it is any faster, but it allows for more values to be sent to the module in this crucial area of slightly opened to closed, thus for smoother transitions to be played.

    There's no way there is much more passive components in the VH-13 compared to the VH-12. Maybe the sensor of the lower cymbal is another model with a different response curve, maybe it's a resistance added to the old sensor, anyway, the module should be able to fully take advantage of the difference of the curve, or Roland could have included cc#4 curves to apply to any existing hihat, but it doesn't as they didn't.

    As is, when you try to set the VH-12 as a VH-13, there's a missing portion, at one end or another you don't get the full 127 values bteween fully closed with pitch pressure to fully opened, and it's not satisfying, if you sacrifice the pitch pressure, you loose the foot splashes, if you sacrifice the complete opened, it's always halfway too closed, and the amplitude of the curve doesn't change anyway, it's as if the hihat itself was limited.

    It's not, it's the module that sets the limit, and you can trick it into thinking you"re actually using a VH-13, and it gives more positions between closed and opened for real!

    How to do this? First it is a fast procedure, but you'll have to do it every time you power the TD-30. Once you have done it fully for the first time it's nothing more than loading a trigger bank from your favorite trigger bank (you'll understand why you'll have to do it from your favorite bank just set after power up), so there's ashortcut to it. You need a usb stick. Save your entire TD-30 data. Then go to Trigger, and adjust you favored trigger bank to something you like. You can play with the offset values of the higat once it is set, and find the optimum setting so that you reach 127 when you step srtongly on the hihat foot. Don't worry if the value you reach is far from the one set by the module, if it still plays it's ok.

    When you're done save you trigger bank to the usb stick. Then press shift+copy, go to tab C, select Trigger, then Preset, and TD-30KV as a source while you select another trigger bank (other than the one you've set) as user destination. Once you've executed the copy, you'll notice in the trigger settings your hihat is calibrated to 0 offset. DON'T TOUCH that setting, and adjust the trigger type and other triggers settings again for the entire kit again to your liking (pad types, tresholds, scan times, etc, set it again because you've just loaded the td-30kv default bank) . Save this new trigger bank to the USB stick.

    If you turn the module off and on again, you'll see it displays a "message " on power up, that's because the hihat is no more calibrated. The hihat will respond poorly, as a VH-12 on the VH-13 type. You have to go to trigger, go to your favorite trigger bank, then press shift+copy and restore your saved trigger bank with the VH-13 trick. You'll have to do this every time you want to use the extra smooth opening, but hey there's nothing for free without a little extra work, right?

    So what happens with this trick? You have fooled the TD-30 into thinking you're using a VH-13 although your VH-12 has been calibrated as a VH-12 : the module listens to the VH-13 cc#4 trigger curve, and interprets your actual VH-12 response curve as a streched curve, or so to say the same again, as a trigger coming from a VH-13. And voilą!, you have extra smoothness in the opening of the hihat, it doesn't shuts so abruptly as it did, you have more room with the foot to express nuances with less efforts to be very precise.

    You find it subtle? It is but noticeable. I bet the difference with the VH-13 is no more than just that.

    That'd be great if users of other hihats could tell if it works as well or not.

    Have fun hacking your TD-30 into thinking you've broken the bank again!

      I realise the trick only works when you simply import the TD30KV triggering preset over your triggering setting. So it simplifies the process, set the triggering to your liking to bank 2, and copy the TD30KV triggering preset over it on triggering bank 1. There you have the VH-13 effect on the VH-12. The triggering settings will read inaccurate values, but it is your setting bank 2 that are actually ruling. The only thing you need to change every time is the snare rimshot/stick switch point.

      It does really make a difference, the hihat opening is more progressive and smooth.
