ScaleSpace 3D is a prototype MTS-ESP master plugin, which allows the dynamic manipulation of the current scale by using an 3D slider to explore the 'scale space' between eight scales.
Each of the eight scales can be set by loading a either a Scala scale file (.scl), keymapping file (.kbm) file, or both. Click "Open SCL File" or "Open KBM File" to choose the file.
The eight corners of the 3D slider represent each of the eight scales, for example, moving the slider to the top left XY corner and moving the Z slider to the bottom left will set the current scale to Scale 1, and moving it to the bottom right XY corner while moving the Z axis to the top right will set the current scale to Scale 8. Different positions within the cube will set the current scale to a different weighted average of the eight scales.
The current scale can be saved as a .scl and .kbm pair by pressing the EXPORT button. To allow for any scale, the .scl file defines every MIDI note from 0 to 127 as a difference in cents from the reference note frequency. The .scl assumes that the reference note will be MIDI note 60, so the first listed pitch difference is assumed to be for MIDI note 61. The .kbm file sets the reference frequency at MIDI note 60, using the frequency of MIDI note 60 in the current scale. The .kbm file also sets key-for-key mapping. NOTE: Attempting to overwrite either the .scl or .kbm will overwrite both files, as they are saved as a pair.
To use these plugins, you will need Scala scale files (.scl) and / or keymapping files (.kbm). You will also need to install libMTS.
There is a large collection of .scl files at the Scala Scale Archive.
A collection of .scl and .kbm files can be found in the Sevish Tuning Pack.
Builds can be found at Scale-Plugin-Builds.
