So this has come up for me lately. When I have tracked part of a song and have some plugins either on a group track or the master bus (this is what I understand top-down to be hence the description in the title, if I'm wrong sorry!) and then want to track some more the added plugins on the group track or stereo bus tend to cause latency on my incoming signal. Now, generally I would just save the settings and remove the plugins (usually seems to be compressors that are the problem) and then track and then bring them back to the mix. But I'm looking for quicker. easier options. I've already changed my buffer size and all that stuff. Is it possible to freeze or disable a group track? What other techniques might be useful? Thanks in advance.
