If you told me HEAT was hardware dependent I would have believed you
But this little button? Every other native DAW (I know it's a tried phrase) has this feature. In a typical Pro Tools workflow (e.g. record to tracks instead off bounce) it's even more important because it helps compensate for the lack of offline bounce. Current problems with Input monitoring (latency etc.) could also be cured with this function.
The lack of it makes Pro Tools look really unprofessional. I hope Avid is aware of that. BTW I got the CPTK2. Take a look at my signature and please vote. Thanks.
