I’ve always found Sonar was much better for working with lots of Virtual Instruments and VST effects. I have orchestral projects in my old Sonar with hundreds of tracks. I just can’t do that in Cubase… would need to use other computers & Vienna Ensemble or similar. The ASIO load was always much lower when I used to use Sonar. On v9.5 of Cubase and I can still get more out of a legacy version of Sonar with VSTs/VSTis
