Access Force Controller

The 'access-force controller can be created using the following Lisp syntax:

The 'access-force controller takes two arguments:

• dimension: number of dimensions of the controller (in this case, please use 1).
• access_reference: an access on an object.

The dimension for this controller should be set to 1.

The access referenced must have connection associated with it.

This is a controller which outputs the interaction force of a connection at an access. It could be used, for example, to acquire the force exerted by one connection and apply it to another object using a 'force controller, as in the following example, which takes the pluck from Modalys example 1 and uses the interaction force from the string to excite the plate from Modalys example 2 (instead of a strike connection):

This results in a very different sound from using an 'access-speed or 'access-position controller.

The image at the top of this page shows force, position and speed controllers obtained from the plucked access on the string and a position controller from the plucking access on the plectrum as given in the Modalys plucked string example.

This was formerly called (make-controller 'connection-force ... ) and operated on a connection, instead of an access. A handful of very ancient Modalys scripts may need to be updated to use the new syntax.
