Advanced Scripting Techniques, Random Playback Scripts
A new tutorial exploring the use of advanced scripting techniques has been created, which uses bit based techniques to generate a random number and jump to a track or story. It checks to see if the track or story has been played before and if so generates a new random number.
The tutorial is theoretical, and doesn’t have a set of files to download yet, but looks at how to track up to 40 tracks/stories. This means that the tracking has to use 40 bit slots, or two and a half registers, leaving the remainder for calculations. This is more than enough, and in fact twice the number of clips could be tracked using this technique.
As it is only theoretical, there may be some flaws in the scripts, but it is offered as a starting point for experimentation and discussion. It uses fairly basic maths for the most part, but makes use of the ‘AND’ operator to compare two GPRMs. Previously, the ‘and’ has been used almost exclusively on this site to mask off different sets of bits.
