A List is defined as one or more points that can be stored in the

synthesizer’s List Point Memory. The synthesizer’s list point memory

can hold 131,071 points (with a range of 0 to 131,070) and can be

broken up into different size lists; although there can be multiple lists

stored in list point memory, only one list can be run at a given time.

Each list is delimited by two parameters that specify its Starting Point

and its Number of Points (length).

We can create a list of points that can be run in various modes. While

running a list, we can control the way in which the list is traversed by

using input triggers, and we can set up the list so that output triggers

are generated after specific events.

To illustrate some examples, we can define a list with ten points. We

can start this list with an input trigger and have an output trigger

produced each time a point in the list has settled. We could further add

an output trigger that is output at the end of the list or at any arbitrary

point in the list, or we could make the list restart to the beginning after

reaching the end of the list or at any arbitrary point in the list.

One or more of the following list modes, which are controlled by the

HPE6432_RunList() function, can be used simultaneously to run list

scenarios with input and output triggers:

• Trigger Input Mode

• Sync Input Mode

• Repeat Mode

• Interrupt Mode
