Part 2: Having built our own beat repeater in Logic last month, let’s now see what more we can do with it...
You’ll need to start with the project I explained how to create in last month’s Logic workshop. If you’re an SOS subscriber, you can find the workshop article at
www.soundonsound.com/sos/jan13/articles/logic_0113.htm. If you’re not (or just prefer not to work through the steps), you can download the project from
www.soundonsound.com/sos/jan13/logicmedia.htm. This month, we’ll add keyboard control to the simple Beat Repeat effect. Keyboard-controlled effects allow the user to send different trigger signals much more efficiently than simply using a mouse.
Go to the Environment, create a Transformer object, and label it ‘Beat Repeat Input’.
Cable an outlet of the Transformer object to the inlet of each of the three buttons created in last month’s workshop.

Click on the ‘Bypass’ button, go to the Inspector and set its Input to Note On, Channel to 1 and the -1- menu to C3.
