Well, since we are on the subject.. :)
Since we have already covered using the multiple audio outs and discussed that there is not much doubt that it is far easier to make the drum track directly on Maschine.. however notice that you can automate scene changes via program change controls from Sonar... use the pull down box in Maschine in the scene area next to project name to enable remote midi scene control and select PC messageds
So, simply setup a one bar blank pattern> scene 1 and insert PC=0 at 1:01:000... this will cover the Sonar count in.
then make patterns at will, and pop them into scenes and insert program change notes ( i use the even list) on Maschines midi track.. (with PC # one less than scene number) then you can play your track end>end.. if you wish to play freestyle, simply mute the midi track.
@bigboi.. that one bar is Sonar's lead in.. either remove the lead in in Sonar or automate Maschine to remove it..
