alternatively have your fixed length gate fun (on the amp too) with env shapes 8-thru-11, the attack phase there (effectively) defines the gate hold !!
This is just one of the many reasons why i think Elektron have given us the best box of tricks money can buy - it is just so flexible and controllable, in outside the box ways !
