Thanks for reporting this. I believe this is a visual bug; the minimum delay time for Head Space will always be 200ms. The tap switch allows you to tap in values that are smaller than 200ms and the parameter will display these smaller values, but the minimum delay time will still be 200ms (you can hear the delay time doesn’t actually change, the parameter just displays smaller values based off your tap value.)

I’ll log this as something to be fixed.

Glad you are finding some useful interesting and useful sounds with Head Space. There’s a lot of space to wrap your head around with this one!
