Danny,

From what Peter Gannon has said in the past, the "fast" processing of Realtracks is a background process. When you generate a song, BIAB will being rendering the Realtracks and when a sufficient number of bars have been rendered, the song will start playing. While the song is playing, the remaining bars of Realtracks continue to be generated. I suspect that you are expecting too much from a 1.6 GHz processor with less than a megabyte of RAM. It might work if you have only a single Realtrack in the mix, but, if you have four Realtracks the background processing would be a huge drain on your resources.

Regards,
Noel
