scalebank2
To be able to use this module, first load the "scaleGenerator" to create a table on your SDcard. This module then automatically loads this table from your SDcard. I found that in big projects, this scaling-array took too many memory. This way the array isn't stored as part of the code, leaving more memory for adding modules.
