Automation issue in Logic/Reaper (AU wrapper)

[ypujante]

Somebody reported issue with long automation using plugins built with the VST SDK and the AU wrapper. This seems to affect plugins built with Jamba as well since it uses the AU wrapper that comes with the VST SDK.

Report:
Jerky automation: Imagine to automate a Mix parameter with range [0, 100] where 0 and 100 are real/plain values changing it from 0 to 100 with a linear ramp. When I automate the VST3 version changes are smooth 0, 1, 2, 3....(small jumps) but when I automate the AU wrapped version I see changes like 0, 4, 12, 20...(big jumps, not fluid).
