I noticed that if I inserted a step mod into a program with the Sync mode set to “Tempo+Beat” that the audio-processing load in Cubase increased with the bar number.
For example, if my transport is playing at bar 9, my audio-processing load meter is normal looking. If I jump to bar 800, it increases a good bit. If I jump to bar 1700 it is almost maxed out.
I tested this locally with a HALion 6 in Cubase 9.5 and I tested this with a HALion 6 loaded in a VE Pro 6 instance on another machine. In VE Pro 6, you can see the CPU usage increasing with the bar number count.
After a series of tests, I narrowed it down to the step mod sync mode set to “Tempo-Beat”
I just tried to make a patch from an initialized patch. At first the step mod did not show the behaviour. The midi module step mod did but after I brought that in the original step mod also showed the behviour. It doesn’t totally seem consistant but here is a simple patch that on my system if I locate Cubase to bar 2000 the ASIO cpu meter shows about 85% hit. Step FIlter Test.zip (8.43 KB)
