Create a CV-I device and connect it to the Hardware Interface device inputs:ĭone, let’s head over to VCV Rack now! Setup VCV Rack We will first try to modulate a Reason device with a VCV Rack LFO. To be able to easily send and receive CV, they convert CV to audio and back.

But here is where the CV-I/O devices come into use. You can already send and receive audio directly to these inputs and outputs. I will probably only use a maximum of 8 channels of CV, so to reduce CPU usage (I’m not sure there actually is any for silent channels) I usually disable the Input and Output channels 11-66:Īs you can see in Reason’s Hardware Interface device, channels 1-2 are now in use with Balance (green LED by the socket), and Soundflower channels 3-10 are available (yellow LED): Launch Reason and select the Aggregate Device as your audio interface. You can rename the Aggregate Device by clicking the name in the list. In my case it’s the Balance (for the speakers) and Soundflower 64-channels (for sending CV). A new virtual interface will be added to the list:Ĭheck the interfaces you want to use. In the lower left corner, click the + and select “Create Aggregate Device”. Open the Audio Devices window, it should look something like this:Īs you can see, there is a list of the available audio interfaces: my Mac’s built-in, my Balance USB-interface connected to my speakers, and two versions of Soundflower: a 2-channel and a 64-channel interface. To do this, open the app Audio MIDI Setup which is located in your Applications/Utilities folder. Think of it as merging multiple audio interfaces into one. To be able to use it at the same time as your existing audio interface, you need to create what’s called an Aggregate Device. To your Mac, Soundflower is just an audio interface like any other.

A download link for the latest build (today 2.0b2) and install instructions are available on the Soundflower’s GitHub page. Soundflower is a free app that acts like virtual audio cables between audio programs on your Mac. It’s a free, open-source virtual modular synthesizer, and works great to use in combination with Reason. The process is similar for Windows, using other apps.Īs the other program we will use VCV Rack.

This tutorial will show how to do this on a Mac using an app called Soundflower. With the new CV-I/O devices, it is possible to send Reason CV signals as audio to and from your external synthesizer, but also to other programs in your computer. Connecting Reason to VCV Rack with Soundflower
