Tracks with Sector

11 March 2014 Leave a comment

Sector (iOS Kymatica) creates interesting tracks by dividing a loop into sectors and providing the ability to jump to any other sector given a probability of that jump.

The examples given tend to use the full probability future where any sector jumps to any other. A more directed approach also provides interesting tracks. The aim of the directed approach is to combine repetition with variation. A track with too much variation can seem jumbled while too little variation will be bland.

For example; with a loop in Sector with 16 sections. 1 – 8 form part A and 9 -16 form part B. Sector 8 has a 50% chance to jump to sector  9 and 50% chance to jump back to sector 1. Sector 16 has a 50% chance to jump to sector  1 and 50% chance to jump back to sector 9. This with break the sequence from A B to AABABBAAABA depending on how the probabilities fall. Changing the probabilities leads to further directions. The jumps within the sections provide additional variation so the sequence is more like A A’ B A” B” A”’ B”’ A””.

From there 3 and 4 section can be used with variations to the probabilities. A sequence could be A c B c A where c is a transition sector. A section A ends there is a probability to go to section c which will go to section B . Likewise at the end of section B there is a probability to section c which then go to section . Alternatively there could be sections A B C where there a different probabilities to jump into those sectors. In all these examples the sections A will sound different from B but similar to each other which provides the continuity.

The ability to change the play back wave forms and their probability of occurrence provides addition variation which is important  for the transition sections.

With 4 possible sector mappings, 4 sequence mappings and the ability to set four sectors as triggers you can play Sector by setting up alternative mappings and sequences and moving between them.
