Sonar Artist - Lame encoder/mp3 encoder

> 1. I don't have this so could this be the reason the audio has no sound.
 
No, the encoder is only used to convert WAV format to MP3 format. Although I did not fully follow your previous posts, there were plenty of good advise given. First, your MIDI should be able to produce sound by (following those advise) playing it back in Sonar Artist. If not, you won't be able to make a working WAV file. And up to making the WAV file, the LAME encoder is not part of it.

> 2. If So, does this come with the COST of Sonar artist or do I need to purchase it?
 
The actual LAME encoder is free, and for myself, I use Audacity (free) with LAME encoder. I simply export WAV out from Sonar, and use Audacity to covert the WAV to MP3. There is an option to purchase an MP3 encoder from Cakewalk (not sure if it's LAME or not) which makes WAV to MP3 more direct.
