that looks promising! thanks, i'll give it a go as soon as i'm home. looks like a good use for a passive decay envelope, which is really easy to build, and small enough to build it straight into the slew limiter module.

thanks for the post,

While the key is held, the output of the AD is low, so the rate of the slewlimiter is low as well. On retriggering CV is added to the slew rate, et presto.
