Thanks Noel... I definitely appreciate your comments...
Well I definitely would want to do it this way like the Ableton freaks can to be honest... I've thrown you a feature request yesterday I'll keep my fingers crossed

Choice is always good thing...
For Gene's benefit and other's here is a thread summary....
Add a dimension pro softsynth track and assign a sound. Now arm and mute it.
Add an audio track. Under input change it to Dimension Pro -> Primary Output Stereo
On the audio track click Waveform preview on.
Record and everything will work as you say, bouncing, freezing etc....
Now delete the MIDI clip you created on the first track, still see the audio waveform on the second track?
Good - try and play it back or freeze it etc :) - Won't - Cos it's just a meter.
Now the Dimension Pro will generate MIDI on the softsynth track when recording, Maschine will not as it's doing it's sequencing internally within the plugin and there are multiple outs,
so to work around this we need to put in a dummy clip to
con Sonar (?) into to recording.
However if Sonar could record the plug-in effect or synth output it would be a lot neater solution (no bouncing or freezing). Cheers...
