ReWire Tutorial Article ProTools - Step 3: Using multiple ReWire channels
In "Step 2: Routing Audio" we set the complete Reason mix to be routed via ReWire to ProTools. But what if you want to make individual mixer settings for a separate device?
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 ProTools, to separate audio channels.
In this example we want add an RTAS effect to a Subtractor sound and add some compression to an individual Redrum sound. We'll need to activate two ReWire channels in ProTools and route the individual Reason devices to the corresponding inputs on the Reason Hardware Interface:
1. In ProTools, create two mono audio tracks.
2. Open the ProTools mixer, and click on an Insert slot in the Mixer to open the Inserts pop-up.
3. Select Reason from the Instrument sub menu. A ReWire plug-in will be created.
4. Select Reason ReWire channel 3 by selecting it from the output list on the ReWire plug-in.
5. Repeat steps 2-4 to create a ReWire output plug-in but set it to channel 4 this time.
6. In Reason, flip the rack around by pressing [Tab].
7. 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.
8. Locate the Redrum device and the drum sound channel to which you want to add some processing. Connect the individual output of that drum sound channel to input nr 4 on the Hardware Interface.
9. Go back to ProTools and start playback.
Now the sound of the Subtractor device and the individual drum sound appear on separate ReWire channels in the 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 Mix L and Mix R ReWire 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 ProTools!
