The Reason Malstrom Synthesizer
(From The Reason Manual)
There are a number of different synthesis methods for generating sound. There is e.g. Subtractive Synthesis (which is used in Reason's other synth - the Subtractor), FM Synthesis and Physical Modelling Synthesis to mention but a few.
To give you a clear understanding of the inner workings of the Malström, it might be in order with a brief explanation of what is calledl Graintable Synthesis.
What we refer to as Graintable Synthesis is actually a combination of two synthesis methods; Granular Synthesis and Wavetable Synthesis.
In granular synthesis, sound is generated by a number of short, contiguous segments (grains) of sound, each typically between 5 to 100 milliseconds long. The sound is varied by changing the properties of each grain and/or the order in which they are spliced together. Grains can be produced either by a mathematical formula or by a sampled sound. This is a very dynamic synthesis method with a lot of variation possibilities, although somewhat hard to master and control.
Wavetable synthesis on the other hand, is basically the playback of a sampled waveform. An oscillator in a wavetable synth plays back a single period of a waveform, and some wavetable synths also allow the possibility of sweeping through a set of periodic waveforms. This is a very straightforward synthesis method that is easily controlled, but somewhat limited in variation possibilities.
The Malström combines these two into a synthesis method that provides a very flexible way of synthesizing sounds with incredible flux and mutability.
It works like this:
