We have released a special version of Derailer for 4-channel audio setups, Derailer Quad. This places you at the heart of the resonator system, giving an immersive sound environment. In this post we show you how to set up the plugin in Logic Pro, Ableton Live and Studio One. Derailer Quad provides 4 channels of audio output, and is intended for use with set-ups that use 4 speakers. Each resonator bar has its left and right output assigned to pairs of channels as shown above. The dry driver signal is controlled by separate gains for each channel. As a prerequisite you’ll need an audio interface that provides 4 or more audio channels, and your host DAW will need to be configured to access them. Different hosts have different ways of dealing with multi-output instrument plugins, so we’ll look at the setup for the hosts that we have been using for testing, namely Logic Pro, Live and Studio One. The basic idea is to route the additional outs called Derailer34 to a separate bus in the DAW, which can then be sent to the channel 3/4 outputs. Accessing and routing is slightly different in each case. Logic Pro The easiest host to deal with is Logic Pro. When you go to load Derailer Quad from the Instrument list, you will be presented with two options, Stereo and Multi-Output (2xStereo). Select the Multi-Output option. In the Mixer view you should then see +/- buttons next to the gain fader. Hitting the plus button will load the Derailer34 outs onto a new bus channel. Then simply route that bus to your 3/4 outputs, as shown in this video. Ableton Live The setup in Live is slightly more tricky, requiring a few more selections. First load Derailer Quad onto a MIDI track. Then go to an Audio track and in the first drop-down under ‘Audio From’ select Derailer Quad. Then in the box underneath select Derailer34-Derailer Quad. Then turn on the Monitor and finally use the ‘Audio To’ box and select Ext. Out to your 3/4 outputs. Studio One Studio One is fairly straightforward. Having loaded Derailer Quad, click the small right-bar arrow button at the top of the plugin window. This should pop-up a small window where you can tick Derailer34 to enable the additional outs. Then, click the ‘I’ button to show the track info detail, and then route Channel 3/4 to your 3/4 outputs. We recommend using one of these 3 host DAWs, but other hosts may work equally well.
