<strong>Thinning factor</strong> ranges from 0 to 1000 with larger
|
|
values sending fewer automation changes. Thinning is like lossy
|
|
audio compression, removing data that is less likely to be noticed,
|
|
although the more you remove the more likely the loss will be noticed.
|
|
The advantage to thinning is reduced CPU usage.

<strong>Automation sampling interval</strong> ranges from 1 to

sampled. The shorter the interval the higher the accuracy but also

the higher the CPU requirements.
