Adding Columns (Machines) to the Sequence Editor
Note: A single sequence column is created for each new generator that is added to a song. The following steps need not be applied for these, but are required to add sequence columns for effects, or additional columns for existing generators.

To add a sequence column, simply Right-click and Select the machine from the "Add Track" pop-up window. Alternately, this may be done by pressing CTRL+Enter, and selecting the machine with the up and down arrow keys. The machine's new sequence will now appear as the furthermost right vertical column.
