6beat6 is a 6-osc experimental VSTi synthesiser. Each osc can generate a sine, triangle or square wave and the osc outputs are combined in a rather 'interesting' way...
6beat6 uses a simple mathmatic process to combine six oscillators. Each osc inputs to a pair of min/max logic filters. These filters will only output the single highest and lowest input waveform values.
The following illustrations only use 3 waveforms for the sake of simplicity:

The minimum and maximum values are then added together to create a single complex waveform:

At this point it all gets rather complicated. Each osc has an influence on the others... Suffice to say, frequency modulation and ring modulation are deeply involved. Somehow. 'Interesting' parameters include series and parallel routing options and the enigmatic N.Q. mode (a stylophonic approach to portamento/glide).
Includes Dan Worrall's rather excellent Tarrabia Filter module - based on the algorithm by Patrice Tarrabia - which is available here.
