hi all when i put a vst synth like serum or uh-e hive and drop a midi file on them in sonar the volume keeps dropping! so if i adjust the volume in side the synths the volume drops down when it reaches the start off the midi file (ive got it looped). But if i use the volume in the mixer it doesn't but i cant get the synth loud enough, but if i use others like synthmaster it doesn't have this problem its only on some synths and they are most off my good ones too any ideas?

Ok ive seem to fixed it it was the midi files them selves causing the problem as i tried another pack and it did not cause a problem!  

You can delete the volume setting from the midi/file clip using the event editor. Look for CC#07 (volume) or CC#11 (expression).

Thanks Sanderxpander the files did have in bedded info so ill try what you said! cheers
