### 3/5 — Great but causes latency

*2020-07-08*

I suppose it’s better on the mastering side, but I wanted to use it on a single track and latency was crazy high. Took off true peaking and still was lagging... ahh well... outside of that best limiter. Cubasis 3 user.

### 4/5 — Latency issues,But still a good Limiter...

*2020-06-19, version 2.04*

When using in Cubasis, depending on which preset you use, you will get a latency issue wher the audio will not be in time to the metronome.
Took me ages to work out why this was happening..

I had pro L2 on the master output, and had to disable it, 
But as I said it depends on the settings in pro L2, 

It is a very good limiter....👌

### 5/5 — Bucking Fig Nuts
