Spider audio merger and splitter in Reason

Published: 2016-10-12

The audio merger splitter in Reason is a utility device which routes audio devices. Ideal the Audio splitter is used for parallel audio processing, while merging is similar as using a mixer with out having control on the volume.

With having a larger article about the CV Merger & Splitter in Reasoner I can be really short about the Spider Audio Merger & Splitter. Since it works the same way as the CV Merger & Splitter but the audio variant only re-routes Audio signals (the main audio output of a device).

While in a way the Audio merger splitter was handy with using a Combinator patch to connect all the other devices to each other by using the splitter, the Audio merger kind of became obsolete with having a Line Mixer 6:2 in the reason Rack. Still there are some nice techniques that you can apply to use this device. Especially the split function can create these really dynamic sounds while having only one devices that triggers the notes.

The rear of the Audio Splitter

When you would add a Spider Audio Merger and toggle to the rear of the rack (press Tab key), you will notice a whole bunch of holes. These are audio inputs/outputs. The spider audio can divided into 2 different segments:
1. Merge Signals (left pane)
2. Split signals.

As I have already mentioned, the merge signals are kind of obsolete, since there are different devices inside the reason rack which do the exact same function but with more precision and control. However, if you want to bind the audio signals together without tweaking volume knobs, then the spider audio merge section can come in handy. The merge segment has 4 input slots and 1 output slot.

The second part of the Audio merger splitter (which is called split audio) still has its applicable usages. Since in a way you are able to use one dry signal and therefor connect it to multiple effects using the same dry signal. A similar effect would be called Parallel Audio processing (which is different then serial Audio processing).

The way this kind of works in the following schematic:

This scheme shows how a audio merger splitter is used to merger certain signal paths in Reason

Audio splitter

Lets kick this into high gear and start with an example on what you can do with splitting the audio. In this example I am going to use a subtractor. The first subtractor has a splitter inside of it which is connected too 2 different phaser units. Each phaser unit has its own rate making it really dynamic in a way. For the second effect, the bass-line, I added 2 different unisons connected to the splitter, which leads into a real nice stereo effect by panning one signal to the left and the other to the right inside the main Remix Mixer.

In other words, you can send one signal to the splitter, reroute it through 2 different devices and create 2 unique sounds just by using one device.
 

Split and Merge together again

With the second example the signals are being rerouted by using one Scream 4 sound destruction unit and a Unison Detune unit. Where you might think, why use the splitter for this? Well, the answer is simple. One signal is being changed by the scream unit, the other signal by the unison. This is a different effect that just adding a scream unit and a detune unit in a row. I'll just demonstrate this with the next set of files:

So there you have a comparison on what actually happens when rerouting the signals separately and join them together separately.
There is a lot of tweaking that you can do between the process of creating a single instrument, and reroute the signal through all kinds of different effects... Just for the fun of it, here's a real big example of what this can do for you. And PS don't take this example too serious because this is just for fun ;)

Practical usages Audio Merger Splitter 

There are a things that would most likely need a audio merger splitter. I will name a few:

- Parallel Audio Processing requires a Audio Splitter
- Merging Audio signals may require an Audio Merger. However one could also choose to use the Mixer 6:2 or Mixer 14:2 instead
- Combinators will most likely be handy for routing audio signals through effect processing units (such as the Scream 4, the Vocoder etc)
- When you want to reuse the same signal more then once, you will need the splitter segment of the Audio merger Splitter

This concludes this short tutorial about the Spider Audio merger and splitter!

Part of it went wrong while migrating the content from the old platform to the new one. I have already replaced the images. I'll check tomorrow where the audio files went off too.
