We have brought this up a few times. Because yes, To run the currant version of Sonar you also need an up to date laptop with good specs.
I am currently using a Asus netbook for live playback at gigs. Sonar is too much for it as it is pretty gutless @ 1.6 single core. And it only has 2 Gigs of RAM. And a lot of folks use tablets now. All is fine if we stick to playing Mp3 or Wave files using a basic music player. But I myself would like to have 4 tracks of audio and a midi track to control lights and effects.
Sure there are some free ware sequencers out there that are low load, but it would make more sense to me to be able to use CWP files.
The wish list is:
Limited track count for audio.
Midi with a few soft synth slots.
