  • E-100 percussion modification idea - has anyone tried this?

    Finding the percussion a bit lame and "plinky" even after modifying it. I'd like it to have a much more profound attack, and then a faster decay. This has me thinking:

    The envelope of the percussion in the E-100 is dictated by the reiteration/keyer module. A DC voltage comes out of it, and its size determines the volume of the perc signal. What if one were to modify the keyer module so that you get:

    * MUCH higher initial gain at the attack of each perc cycle. Close to overdriving the perc amp
    * Faster decay, and also not as linear - more of a logarithmic dropoff than a straight line

    What do y'all think - am I on to something?

    You can also make the first bussbar contacted the perc bussbar.
    Tried this on an L100 and bingo,it sped up the attack.
    Diving board keys have more 'travel' at the ends of the keys than waterfalls.
    I tend to play them 'deeper'.

    Those crude early 'envelope follower' circuits with 're-it' have about the same response as the earlier tube circuit on AO28/29.
    Keying diving boards earlier in the travel might help you enor.
