cruisinon2 Posted January 23, 2017 Share Posted January 23, 2017 I think you have misunderstood what is happening with this re-routing - the E string piezo is remaining under the E string - they are simply plugging it's output wire into the board input socket for the A string - then they do the same for the A string but plug its wire into the input for the E string. So the mechanical string/piezo combo is the same - it is just going into a different input on the PCB board. Now - as we are keeping all the components of the E string together - we would expect the plink to continue to come through loud and clear when we play - however - in this scenario the plink mysteriously "disappears" from the E string - in other words - they can play the E string and no longer hear the plink - so somehow it has been filtered out. Conversely, as we are keeping all the components of the A string together we would expect to be able to play that without any plink as before - but that is not the case - when the A string is played they can now clearly hear the same audible plink that was plaguing them on the E string. So whatever was filtering it out from the A string before is no longer working when using the different input on the PCB board. If the source was entirely mechanical, and the electronics and software had no filtering in place, then it would not matter which input on the PCB board you move that string/piezo combination to - the plink would still be audible when you play that string. The guys that have tried this have said that the plink disappears from the low E when they do this but instead they then get a plink when they play the A string which is now routed through the input that previously was used by the low E. As the physical situation is the same, and all that has happened is the wires have been swapped on the PCB inputs, then how can we explain how the plink now manifests when playing the A string and not the low E ? The implication is that the electronics/software are actually doing some filtering which removes the plink - why else would the E have the plink when plugged into PCB input 6 but not when plugged into input 5? And why would the A have no plink when plugged into PCB input 5 but then have a plink when plugged into input 6? I hope that has clarified it. Thank you for so clearly elucidating what I was trying to say...don't think I was ever going to get that point across. ;) Quote Link to comment Share on other sites More sharing options...
