Core ADSR digital retrigger click problem

    Hi guys

    I'm using the ADSR core cell that comes with Reaktor. I've added a hold envelope to the gate (with the same control as the attack), as the AHDSR envelope in primary doesn't have an option for digital retrigger. It is important for me that the envelope restarts every time it is triggered.

    This is working fine in my example, except I'm getting annoying clicks occasionally when the envelope is retriggered. Does anyone have any suggestions for how I can avoid this.

    Thanks

    the annoying clicks are caused by restarting the envelope.
    i'm not sure if there's an easy solution other than using the 'analog' style envelopes. there are probably anti-aliasing algorithms you could apply but i'm not sure exactly how it would work. i doubt it would be easy.

    Thanks salamanderanagram. Yes, I think looking into anti-aliasing algorithms is a bit beyond me. However that got me thinking a bit and realised that putting a LP filter after the envelope would give me a balance of both (with some control). I've managed to find a good compromise, where the envelope doesn't necessarily retrigger all the way from 0, but close enough for it to sound right to my ears. It seems to have eliminated all those terrible clicks.

    By the way, thanks for all your tutorials. They've been such a huge help to learning Reaktor.
