I have always been a fan of Cakewalk's pro audio software. I went over the forum and did not find something like what i'm about to propose. If it has been done already, just let me know (just in case i missed it).
What i'm proposing is a topic about new implementations that can be done for Sonar throwed in by users, so the people at Sonar can select whether to do it or not and can make the software even more user friendly and .
A couple of things i can think of are:
*Have the ability to make a radio edit version of the project without destructively doing so and being able to do it from inside the project. Meaning, no new file will be created. It could be some sort of a view but the program has to read only the information visible to the radio edit, leaving out (hiding) regions and sections but not deleting them. For example, you have a song that has the following structure:
Intro verse chorus bridge chorus (just as an example)
For the radio edit you want to leave out the bridge, so you can "hide it" from the reading path of the project and leave it out. But it can be recovered and worked with by choosing the original version from let's say, the tools menu or view menu.
* Being able to add envelopes to multiple clips at the same time
Selecting multiple audio clips and right clicking so the popup menu appears and choosing the desired envelope.
* Being able to edit midi with a view of audio clips at the same time.
* Being able to insert a measure or change a measure in the meter/key and make sonar roll over all data to the right of the insertion to keep it synced.
Note: I've version 8.5 of Sonar, so i don't know if any of these have been implemented in latter versions.
