its an old issue and you find many postings, but none of the solutions works for my purpose. the grooveduck example is perfect for loops, but i do not get it working well with triggered playback. [trapezoid] is too slow i think, and line~ well, i just don´t get it done.
the problem is bass tones, especially fast kick drums. when the same sample buffer is triggered a second time, before the first hit playback has cometo en end, it clicks. i tried fading down to zero before triggering again, but it is not really solid.
