Upsampling x2 ,possible bug

Recommended Posts

Hi people.
I've discovered a new bug.
It is no big,but it's a problem to me.
I have some automation envelope in a track with a delay (H-delay from waves ) ,with normal play all works like charm,but when i turn on x2, the automation do not response to envelope.
I've made some test with another projects and i can reproduce continuosly.
 I think is a bug.
Only when x2 (oversampling) is turned on.

PD: the plugin ( H-delay) ,dont have activated upsampling in render and dont have activated upsampling in play either

No,only automate the send to this plugin.the H-delay  is inserted in a buss and i automate the send envelope to this buss.

When x2 is active the send envelope dont work 

When x2 is off all works great.

Some plugins simply do not work well with up-sampling.

In particular, most 32 bit bridged plugins end up playing twice the pitch... I suspect a similar thing is happening with H-Delay.

Just as an aside, there is no good reason to oversample a delay.

It depends,

if the delay adds harmonics and they are not correctly designed, they cause aliasing, so it would make sense to activate upsampling.

However, as I have mentioned, the delay in question does not have upsampling activated either in render or in play, other plugins are those that have it activated. But the envelope sent to the bus where the delay is located did not work if x2 is activated.
