Thanks! I came up with the little hook on a synth-vibraphone. I doubled the line on guitar and the vibes got buried in the mix. I had ambitions of it being a sax or a rhodes instead, but best laid plans...Xtelesquierx came up with a really nice melody/hook that became a good platform for the rest. That's what I needed but just didn't have the creative juices flowing, I guess.
ASATKat, I did the following:
1) Used metronome to determine tempo as 79 bpm
2) Split backer stereo channels and inverted one channel to cancel original bass line - sometimes this doesn't work, but it did this time - original keyboard and percussion remained
3) Used BIAB to create additional drum track
4) Played new bass line on guitar
5) Pitch shifted bass line down one octave
6) Played solo
7) Mixed out original track for bass/(new) drums section partway in
8) Mixing, eq, reverb, etc.
Fun. Audacity program meets all my recording needs so far.
That's just the chorus offered on the front panel of my Katana, it is sweetly smooth and almost out of the way.
