Layout your song structure/chord sequence in Biab. Selected the SmJzPop style. Generated the tracks and saved. Opened in Realband, selected bars for Sax solo and generated, then same for the Guitar.

I selected about 4 bars of the guitar part and used the audio harmony in Realband to generate a 1 up harmony.

In Realband, I set the "default track category" (they are DX Plug In effects) for each instrument and adjusted to taste via the mixer. I added the Tremelo Plug In to the E Piano and Rhythm Guitar as well. Then I added a PG Reverb in the Aux 1 slot. That gives all of the instruments the same Reverb setting. Adjust knob 1 on each track for amount to be applied to each track.

It took me about 40 minutes to have a WMA file of the song and 3 hours to make the video, lol.
