So i think depending on the material and how well it is handled internally it may be an unfortunate bi-product of the loop point scheme they’ve adopted
i started a similar thread which didn’t really take off nor resolve my issues with this
i stand by my comment that with years of looping i’ve never found a device be so unusable in this respect - it gives me hope it can be addressed, but it’d take an effort on the users part to demonstrate explain clearly what is wrong - PU machines seem to be of the least used, so there isn’t a good community impetus
hopefully we can keep this or that thread going 'til we get some official insights"
