Please Help! Sonar 4 And Reason.

[AdamRave]

At this point i am using sonar4 and the latest version of reason.

my sound card is an M-audio usb pre.

when i open reason, i have no issues using it what so ever, same with sonar.

but.. when i rewire reason into sonar and try to play my midi controller (through reason) there is serious latency.

i know where to change the latency in reason but not sure where to look for it in sonar.

what i'm trying to do is write synth parts for a song i recorded guitars and vocals (in sonar) but again, there is a lot of latency happening with reason.

hope this doesnt sound too confusing.

hope to get some answers.

Thanks!!
