chulaivet1966 nailed it!

First off, a hardy and sincere Welcome!

I'm not a great book-learner so I offer similar advice. Just jump in with both feet and know that you are among the most wonderful, knowledgeable, musicians on the planet who hang their egos at the door.

First step: acquaint yourself with the GUI (Graphical User Interface) to learn the buttons and controls and what each one does.

Step 2: Enter some favo(u)rite (Canadian spelling) chords.

Step 3: Hit PLAY (or Space-bar) to start/stop.

Step 4: Experiment with different Styles from the Style Picker dialogue menu.

Wahoo! You're a composer!

If you hit a wall, shout out and someone will throw out a lifeline.

We've all been in your shoes at square #1 and won't flame you. That's something that sets these forums miles apart from others I frequent.

Again, welcome!

"Have fun!" - Dr. Peter Gannon
