Long Delay Plugin

Hi there,
I just started to work with Elk on RaspberryPi with the Hifiberry hat and am absolutely thrilled. So, I managed to run a few plugins and control them with an external midi device.

I’m currently working on a sound installation for playgrounds which provides a long delay. Does anyone now by chance if there is a way to extend the example plugins delay length? Or, whether there is a plugin which provides a longer delay. I would like to have a length around 2500 - 3000ms.

Glad, for your input and thanks in advance, Max
