[Answered] How to record audio of an VST ?

Place a note past the end of the song on the MIDI or instrument track
Enable "Echo On" on the MIDI or instrument track
Select the track(s) associated with the synth
Bounce the track(s) with "Fast Bounce" disabled, "Audible Bounce" and "Live Input" enabled
Play synth while the track(s) are being bounced.
 
Or use a VST recorder like HGS WAV Recorder and import the recorded wave
Or use a loopback through the audio interface

You can probably also do it with a virtual loopback in software using something like Virtual Audio Cable, but I have not tried that myself.
 
The only cogent argument I have heard for the lack of a flexible routing box in Sonar is that the current setup prevents inadvertent feedback loops. It seems to me that software could be written that would warn or avoid that without giving up on more useful routing options altogether.

 
 
SOLUTION
 
Hi, I played around with some ideas from this forum and I found some different solution. The third one is too complicate to use it daily, but it let You record a bunch of tracks simultaniously without any re-encoding or D/A-A/D conversion in 48/24.
 
Solution 1:
Use an integrated loopback device, if Your audiodevice supports this. In my case my Focusrite Saffire Pro 40 supports only one with 2 Channels, but other devices (ESI ESP.. maybe?) supports up to 8 and more channels for direct loop-back recording.
 
Solution 2:
Via hardwire: I route 4 stereo-outs from NI Maschine to the 8 ins of my adat-interface (Behringer ADA800), which are connected directly via wire to the 8 ins of the interface. Not the best solution (noise, latency), but easy to handle. Maybe it´s also possible to connect the adat-out with the adat-in via optical cable .. ? I don´t know.
 
Solution 3 (best but complicated):
I installed Virtual Audio Cable (VCA) Software Version 4.13 (!)
I created 9 virtual channels (set to 48kHz to 48kHz) in VCA
I installed ASIO4ALL and activate the 9 corresponding virtual devices as the main asio-device in Sonar X3
I added Maschine 2 (or any other plugin) as a VST in Sonar and set the groups/sounds to different External Outs 1-8 (or more if You need)
I use 8 Stereo-tracks with input Machine EXT-1, EXT-2,... EXT-8 and output the VCA outputs 1.1, 2.1, 3.1, ... to 8.1 in Sonar. This tracks has obviously no record-button.
I added 8 additional (!!) audiotracks using each of the 8 VCA channels 1.1, 2.1, 3.1, ... to 8.1 as input of the tracks.
I open 9 instances of the Audio Reaper and route channel 1 to 9, 2 to 9, 3 to 9, .... 8 to 9
I route channel 9 to the real hardware audiodevice (in my case the Saffire Pro 40) with the last (9th) instance of Audio Reaper). You need to do this because You need to listen to the sum of all tracks on Your real audiodevice! Don´t forget: Sonar is still working with ASIO using only VIRTUAL devices.
Now I arm the 8 additional tracks for recording, start record, perform on Machine and all 8 tracks (or up to 16) are recorded directly as waves into the 8 stereotracks. And this in realtime. There´s no gap in this recording on my system. If You have some, simply select all final tracks and drag them to zero-position.
 
I know that this last solution is complicated, but it works. For sure I wish Sonar would directly support such virtual channels or the opinion to records vst´s directly...
Hope this helps
