"I don't get what you mean. You can audition both audio and MIDI from CbB browser, and you could in Sonar, too, since ages ago. The only limitation I find is that for MIDI you can only select a VSTi as output, and not a hardware external port."
It's been a while since I used Cakewalk for a music project, and I was imprecise in describing this issue.
I wanted to be able to click on a MIDI file shown in the Browser, and have it automatically play my Korg Kronos (external synth). But in Cakewalk this wasn't possible. I had to put the file on a track and press play in order to send the MIDI data to the Kronos. Much slower when auditioning a whole folder of MIDI files. Not a huge deal or enough to make me ditch Cakewalk, but as I discovered when TSHTF, Cubase hath other charms.
I used Cakewalk for ~20 years and still appreciate its depth and features, but I use Cubase for music now, unless I'm doing a remix of an older project.
