Converting Midi data to audio

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!

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.

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.

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?
 
 

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.

Hello all, Sorry for the late response and thank you for all your help.
All tracks are playing but when I freeze ANY track that is when it crackles and pops.
I dont think the crackling has anything to do with on/off midi notes as you explained because all the midi data is actually playing fine.
