The keyboard style files contain a number of sections:
• A MIDI section, where the MIDI information is divided into parts. Read more here.
• A CASM section, where the Ctab are set. Read more here.
• An OTS section, where the One Touch Settings are defined. This document describes this section. Reference for OTS software programmers.
• A MDB section, where the Music Data Base records are set. Read more here.
Read about style format differences and how to convert between models at Style File Features.

OTS sections can be created and edited with my OTS Editor software.
