Unfortunately, I can't embed a video so you will need to click on the link above. For those that use the ePro Live drum kit, I think you will see right away how the rim sensing in this video is much more realistic than on the current ePro Live set-up.
This video demonstrates that it is possible using the concepts based on the Pearl REDbox Velocity Switch schematic that I posted back on October 2011 (see this topic: R.E.D.box, Velocity from a Cymbal Switch and Rim Zone [SOLVED]) does in fact work on a Tru Trac drum trigger.
Because I wanted to use as much of the actual Tru Trac's PCB as possible, I modified the schematic slightly. Instead of the switch zone on the tip (as shown in the original schematic), the switch is now on the ring. This keeps the instrument assignment within the module the same.
There is an issue that I don't like about this method. In order for this to work, sensitivity (on the trigger input for the rim) and volume of the instrument need to be set at maximum (99). The reason for this, the Tru Trac head zone is so well isolated from the rim that not much vibration from a rim hit makes it to the head piezo sensor. For that reason I'm currently working on a new approach to variable rim velocity on a Tru Trac trigger. That will be test video #2.
More to come…
Side note: Sorry about the video quality, I'm using a new camera and for some odd reason the video didn't convert well.
