Jointly developped by Line 6 and Freescale Semiconductor, the ToneCore DSP developer kit is a solution for DSP (digital-signal-processor) software developers who create custom sounds for guitarists. The kit enables third-party audio DSP developers with little or no electronic design experience to quickly program audio-effect modules for Line 6 ToneCore guitar pedals. The kit contains a special Line 6 Developer ToneCore Dock, which - in addition to containing the Freescale Symphony audio DSP, audio circuitry and ToneCore Module docking slot - can be connected directly to a PC. The ToneCore Programmable Module is customisable and stores DSP code in the Flash memory of the on-board Freescale microcontroller. DSP-code development is performed on the PC; then, a programming tool is used to Flash the MCU with the new DSP code through the Developer ToneCore Dock.
