ReWire Tutorial Article Logic 8 - Step 4: Using multiple ReWire channels

In Step 2: Routing Audio we set the complete Reason mix to be routed via ReWire to Logic. But what if you want to make individual mixer settings for separate devices?

Flip the Reason rack around by pressing the [Tab] key. Each input jack in the Reason Hardware Interface corresponds to a separate ReWire channel. Each of these jacks can be routed to separate audio channels in Logic.

In this example we want to add an Audio Unit effect to a Subtractor sound and add some compression to an individual Redrum sound. We'll need to activate two ReWire channels in Logic and route the individual Reason devices to the corresponding inputs on the Reason Hardware Interface:

1. In Logic, create as many Auxiliary Channel Strips as you need ReWire inputs.

2. Activate Reason ReWire input 3 for the first track, and input 4 for the second track, using the same method as we did in Step 2: Routing Audio.

3. In Reason, flip the rack around by pressing [Tab].

4. Locate the Subtractor device and disconnect it from the Reason mixer. Instead, connect it to input nr 3 on the Hardware Interface at the top of the rack.

5. Locate the Redrum device and connect the output of the individual Redrum channel to input nr 4 on the Hardware Interface.

6. Go back to Logic and start playback.

Now the sound of the Subtractor device and the individual drum sound appear on separate ReWire channels in the Logic mixer. You can make individual mixer settings for these, add effects or EQ and route them as desired!

In this example we used Reason's mixer to mix most of the devices to the RW:Mix L/R channels and only routed a few devices directly to the hardware interface. This is one way to work; alternatively, you could route all devices to separate ReWire channels. If you choose this option, you don't need to use Reason's mixer at all - all mixing is done in Logic.
