Odd u-he plugins bug in Renoise: knob values incrementing after mouse button release

Greetings fellow u-heans.

I have encountered an odd bug in the behaviour of a few u-he plugins in Renoise on Mac. I've recently switched from Logic to Renoise, and I've noticed that in Zebra 2, ZRev, Zebrify, Zebralette and Tyrell, there is the following interfacing bug: when you grab a knob and drag it to change the value, the value will shift up by between 0.01 and 0.5 a value as soon as you release the mouse button. Interestingly enough, this bug doesn't seem to affect ZebraCM and Triple Cheese.

Needless to say, this makes it somewhat difficult to accurately set values with the mouse, as you have to drag to a value under what you are after to compensate for the increment that happens when you let go of the mouse button. A bit tedious! The problem also affects shift+drag settings, although not as reliably (i.e. for some reason, sometimes it's OK).

Has anyone noticed this? Does anyone have any idea what is causing this? I never noticed this problem in Logic, and I haven't seen behaviour like this in any of the other plugins I use in Renoise.

Hoping you might be able to help.

I used to have that problem (I can't remember which versions), but the latest betas seem fine in all resolutions.

I *think* I've been getting this ever since upgrading to OS X Lion, and can confirm the odd jumpy behavior with the latest betas in Lion.

Oh wow, I've been getting this behavior in Logic from the beginning but I've always figured it's because I'm using Apple's weird buttonless trackpad rather than a proper mouse

Can't confirm that the latest betas fix the bug like Howard said unfortunately because I'm on ZebraHZ and haven't bothered to contact support

Thanks for the replies. Good to know that I'm not the only one experiencing this!

Perhaps a fix might be coming in future versions?

@xh3rv: Hey, nice of you to mention that! I'll PM you so we don't bore everyone with Osaka talk.

Please try the current public betas... if it isn't fixed for you, we certainly need to know as soon as possible :)

OK, I've just installed public beta 2.5.4, and I can report that this version also exhibits the same problem. It almost seems timed based: the problem is intermittent, as if there is like 4 seconds of normal knob behaviour, then a few seconds of this irregular incrementing value problem. I tried to determine a pattern to the behaviour, but there didn't seem to be one, so I guess it isn't time related! :)

I booted up Logic Express and found that the problem is present there too, so it isn't a Renoise thing. Perhaps it is something to do with Lion?

Ok, caught that one. In Lion we get odd mouse positions when dragging, but always integer positions for mouse up. That's very, very crazy.

So now we'll disregard mouse up positions and only use mouse dragging information.

Expect workaround soon 8-)

Oh fantastic! I'm glad you could find the problem. Looking forward to the fix.

Thanks!
