the randomness behaviour of the reverse delays in TimeFactor is the same exact aspect that has made this effect a classic from the H3000 on…in the thoudands of records you can hear this effect. It may take a while to get used to but it's definitely worth. As I said we may consider developing a different way this works, probably more similar to a normal delay.
As for the looping, yes it's not a dedicated looping device so you should not expect all the features a looper offers…pretty much like this opposite is true. A looper won't offer all the delays variety a dedicated delay does.
As you have read though, we are open to suggestions and may add/change aspects in the products. That's what a constructive advice will greatly contribute to.
