Configure Control Surfaces for SCRATCH


GENERAL

This document discusses the Control Surfaces and how to set up each panel based on what version of SCRATCH you are running. With the release of SCRATCH version 7 (V7), we implemented a more simplified way of setting up the Control Surfaces. Set-up scenarios are straightforward.

Each section will cover a specific panel set and either have a link to an existing V6.1 article or go through the new setup for V7. At the end of each panel section there will be a link to the needed driver if necessary.

Note: For any version leading up to V6.1, set-up will remain the same.

Note: For each panel set-up there is an option called "Overwrite Mappings." Read the description from the link. before proceeding. Here.
