Hello all,
 
This is a two part question. Forgive me in advance. I recorded a soft synth track. However, I only get sound when I start at the beginning of the midi track. When I start the (now time) in the middle of the midi track all I get is silence. Can someone explain? Is there a way to fix that?
 
Second question:
Since I only get sound from playing the midi track from the beginning and no where else,  I thought I could bounce the midi to an audio track and overcome it that way. However, how do you do that? Is there an easy way to do so?
 
Ive tried freezing the track because Ive read its like doing the same thing as bouncing to audio, but when I Freeze the track and press play, all I get is crackle and no sound.
 
Thank you all again for your help!

Are you starting playback in the middle of a long, held Midi note? If so, Sonar won't pick this up.
If you're starting playback slightly before the beginning of a note then they should all play.
 
Things to check for the notes that aren't playing:

• Midi channel (they should all be the same as the notes that play correctly)
• Velocity (lower velocities might not get heard)
• Range (is it outside of the note range for the synth you're using)
• Can you see Midi activity on the meter when it's attempting to play the silent notes?
• Do you have any automation that is lowering the track fader to -INF during play

Which soft synth are you using, just for sake of curiosity
How did you insert it? Is it a simple instrument tracks or split Midi/Audio
Can you hear the notes sounding out if you click on them individually in the Piano Roll View?
 
What's your system specs (yeah I'm incurring the wrath of at least one member here, but the answer you provide could be vital). Please list everything you can think of - CPU, RAM, HDD's, Interface, Driver version etc.

for a temporary "bounce" simply select and click the synth track and choose FREEZE SYNTH from the options. It bounces right to the track and a simple click unfreezes it. Of course Bounce to track is always an option that creates a new bounced track.

I'm gonna have to agree with Bristol_Jonesey on this one. How long is this MIDI track that you recorded?  It's possible that SONAR is just not catching the "Note On" message in that MIDI tack. This may explain why it plays from the beginning and not when you start in the middle of the recorded data.

The crackling part of this query is off-putting.  Does this repeat the same process when you right-click on the FREEZE button, select "Freeze Options", and uncheck "Fast Bounce".  Same crackling sound? 
 

Thank you all for your responses.
Bristol, I think you are right. I was using cakewalk sound center and did in fact hold out a long note. I did not know that cakewalk wouldnt allow you to hear these long notes started half way through a track. hmm. This creates a problem because the long held out note is the meat and potatoes of my song, which means that when I record vocals I will in fact have to start at different places withing the song to record vocals.
Would it be easier to just bounce to an audio clip?
If so, What is the easiest way to do so?
Or just freeze the track?
Like I said before, when I freeze a track it converts it to audio, but when I hit playback it crackles, pops and I hear no sound.
 
I did insert sound center as a simple instrument track.
 
In response to DAN. I have not yet right clicked on freeze and unchecked fast bounce. What is the difference? I will try it out shortly and give you my feedback.

Matthew, a couple of things.
 
Firstly, convert your Simple instrument to a split Midi/Audio track.
 
Do this by right clicking in the track header and choose "Split Instrument Track":
 

 
This will give you much better control of your midi activity, and SIT's have been known to casue 1 or 2 problems in the past.
 
Now, on the Midi track, click the "Freeze Synth" icon.
 

This will render your Midi to Audio
 
Now play it back and if all is well you can proceed with overdubbing your vocals. if not, please report back so we can investigate further

Bristol, Thank you for the help. Unfortunately your method did not work. I did everything you stated and I still get the crackling and no playback. This one stumps me. Any advice?
 
 

And all other audio is playing back normally in the project, only the frozen one crackles?
Some more info on details might be useful. What audio interface are you using? What driver mode? What buffer size/latency setting?
 

Something to note: regarding the NOTE ON/NOTE OFF in midi.
 
If you edit a part and for example a note in the passage is slightly off time from being played live and the player hesitated a bit when playing that note..... and there is a note that preceded it that was the same musical pitch.....
 
Now you decide to fix that hesitated note and of course the easiest thing to do is to go in and simply move that note forward in time the necessary distance to put it where it should have been.... easy enough to do in the midi edit mode.
 
Now you play it back and it's not there. It's on the screen but doesn't play.
 
This is another case of the on/off midi signal playing havoc in the time line. The note that preceded the edited note is the issue. When you moved the "late note" up, it's on time was placed before the first note's off time..... so the original ON1/OFF1 ...ON2/OFF2 of the original midi became ON1..ON2  Off1...OFF2 and the second note effectively was shut off.
 
Make sense?   This used to really throw me off until I figured out what was causing it.... so now, I know to edit the duration of the first note to shorten it sufficiently so that it shuts off before the edited note's starting "on" point occurs.

i ran into a similar problem with midi and instrument tracks due to the fact that my computer is not the fastest in the world,so after freezing my synth's,i go to track menu then bounce to tracks and send all the tracks i need to audio tracks,put them in a track folder and play the audio tracks when you want to lay down other parts of your song,no more cracks and pops that way and it always played no matter where in the time line..
