I’m a great fan of SONAR and use it pretty much exclusively on my own production jobs (Cubase SX3 at Product23) and as of I think version 5 you could use icons in the various trackviews for a nice at a glance check on what tracks were doing.
This is great for FX sends and group tracks and so on. When this feature came out I set off creating a bundle of Icons for my own personal use and I’m making these available for download here.
Here are a few examples of what’s in the pack so you can get a feel for what your getting. In the downloaded RAR file there are a total of 147 .BMP files all pre-formatted for use in SONAR.
