At idle with just Sigmund it uses 5% CPU/ASIO. Scrubbing the transport cursor doesn't do much but make it fluctuate between 4-7%.

I've tested this with just one instance of Sigmund in the project. It doesn't seem to make a difference.

There don't seem to be any CPU peaks.
- What exactly version of FL Studio 12 do you use?
It occurs in the latest normal version v12.2 build 3 and the public beta version v12.3 build 34.
- Do you run it in 64bit or 32bit mode?
I confirmed the bug in both 64 and 32 bit FL.
- Have you installed Sigmund 64bit or 32bit?
64 bit.
- Does it differ when you try to use some generic ASIO drivers like ASIO4ALL?
The bug also occurs with the bundled FL Studio ASIO. I can also try ASIO4ALL if you want.
To simplify when exactly the bug happens: it's anytime the plugin is "reset".
