Hi　(I'm sorry not good at English.)
Does anyone fix this MFX issue?
This issue happen from sonar X1 to X3e.
 
method to get issue.
1. Input note 2bars.
    ex:4/4 1st bar"C C C C" 2nd bar"G G G G" with quarter note.
2.Add any MFX to the track.
3.Loop play　only 1st bar.
4.You can listen with 1st bar & 2nd bar mixed.
 
Thanks
 
 
 

Yes it's still an issue that an MFX anywhere in the project will cause all or part of the measure after the loop end to be played back along with the notes in the first measure on each iteration of the loop. This is a soft synth buffering issue that doesn't affect MIDI driving hardware synths.

I see. I hope cw will fixes it, because "transpose" is useful.
Thank you!
 

If all you are doing is trying to transpose, couldn't you use the KEY+ parameter in the Track Inspector for the given midi track?  (There is a little slider for adjusting it, but it is a GIANT pain in the patoot to use it, but the + and - keys of your number pad will increase or decrease the transposition one step at a time, so +12 would be up one octave, etc)
 
I do this all the time - I actually don't ever apply midi effects.  Anything I do is either like above for transpose, or I simply apply audio FX to the audio track that is connected to the output from its corresponding soft synth.

Good point that there's an easy workaround for Transpose. I use MFX most often to block CC123  (All Notes Off) from my controller that breaks sustain functionality with some soft synths that don't handle it properly. Unfortunately there's no workaround for this within SONAR other than to go ahead and use an MFX (TenCrazy's Sustain Fix works better for this than Cakewalk's Event Filter) and remove it when I'm done recording.

Hi Bob.
 
I have never used KEY+ parameter.
but It will be very useful with your tips!
Thank you!

I try to use it!
Thank you!
 
Everyone very familiar and kind!
I am very thankful.
 

Quick question, does this happen with all MFX plugins with Sonar? We are sure this is a Sonar bug?
Thanks...

Hi CakeAlexS.
 
YES, all MFX have this issue.
 

Thanks... Reported under CWBRN-25707.
