"Hidden groups" would be user enter-able "variables" that would go upon the limit of 1-8, and would be called on by special blocks, such as timers, AND gates, NOT gates, etc. With this, a user could set up a scenario such as "Activate 12 after 3 seconds of activation of 3" or "activate 23 when 1 and 2 are activated". Applying this to controls such as pitch, could allow many complex creations to be made.
