Learn the know-how on Reason 3 from the answers to the most often-asked questions.

How to Reason

Using The Combinator

Select two or more instruments, samplers or effects in your rack and hit combine - This bundles them together in the Combinator module from where you can assign any of the combined instruments' control parameters to one of the 8 rotary controls on the Combinator interface.

Record Fader Automation on Mixer - How Do I?

Oddly, Reason doesn't automatically add a mixer sequencing track - What to do?

Hit Create » Sequencer Track

From the drop-down menu (on the right of the new track) assign the track to the Mixer.

Click the left-hand side of the sequencer track to display the MIDI icon.

Hit record.


Setup The BV512 Vocoder

Create a BV512 vocoder, a Malstrom synth and an NN-XT sampler.

For the synth: choose a pad patch (preferably one that covers the whole frquency spectrum and is not heavily filtered).

For the sampler: a vocal or drum sample.

  • Connect the Malstrom output to the BV512 carrier input.
  • Connect the NN-XT output to the BV512 Modulator input.

Hit record.

  • Using the Malstrom, play a short synth sequence.

Hit play.

  • Trigger a vocal or drum sample as the synth is playing back.

The sample should now be modulating the carrier provided by the synth.

Create a Sub-Mix using Line Mixer

By feeding the multiple outputs of one or more sound modules into the Line Mixer you can create a sub mix for a group of instruments. For instance, a sub-mix for drums, another for synths etc....

Connect the outputs (from the Line Mixer) to a channel on the 14:2 Mixer and control the overall level of the submix using just a single fader.

Several Instruments But Only Hear One

The reason you can only hear output from one instrument is that you haven't created a mixer... or you've created a mixer, but after you've created your instruments.

Reason Cables - Quick Guide

Thick Girth vs Thin

  • Thin cables in Reason denote CV (control voltage) cables that carry electrical signals from one place to the other.
  • Thick cables carry audio signals from one place to the other and eventually connect to the mixing desk.

Cable Colours

  • Red cable denotes a direct connection, eg: Synth to mixer channel, mixer channel to hardware interface, Redrum channels to mixer channels etc... (Don't worry too much about the slightly different shades of red.)
  • Green cable denotes a chain with an effect in it - or an effect in its routing somewhere - Example: Aux send, FX returns, inserts etc...
  • Yellow cable could be for things like modulation routing, CV etc...
