Piano Mapping and Tuning Workflow Overview
Introduction
This section provides a detailed walkthrough of the process for mapping and tuning a piano using the Littau-Conrad (LC) Spreadsheet in conjunction with the SAT system. The workflow focuses on establishing reference points, entering target tunings, making necessary adjustments, and exporting the finalized tuning for use with the Inventronics Piano Manager software and SAT system.
Establishing Reference Points
The mapping process begins with the use of A4 numbers and mapping notes to set foundational reference points. These A4 numbers, along with the “4th” A4 number, are instrumental in initiating the mapping. By combining these with the newly identified location for A3, effective starting points can be determined for notes that have not yet been mapped. The relationships between the A3/A4 2:1 octave and the A3/A5 4:1 double octave are readily apparent when reviewing the mapping notes.
Entering Targets and Arranging Notes
Targets for each note are entered into the Templates Tab of the LC Spreadsheet. The arrangement of these targets on the notepad is demonstrated, providing clarity on how the mapping notes and A4 numbers guide the placement of each target. This systematic approach ensures all relevant notes are accounted for in the mapping process.
Tuning Adjustments and Corrections
The LC Spreadsheet offers the ability to tweak the midpoints of the 3rd and 4th octaves during the creation of the tuning in the Adjust Tab. Additionally, rounding errors—also referred to as round-off errors—can be identified and corrected within the Edit Rounding feature. These steps help to refine the tuning and enhance overall accuracy.
Exporting the Tuning
Once all targets and adjustments have been finalized, the tuning is transferred to the ‘Export to Piano Manager’ Tab. Here, the tuning is appropriately named, saved, and ultimately exported for use in the Inventronics Piano Manager software. This enables the completed tuning to be sent to the SAT system for piano tuning.
Conclusion
This workflow demonstrates the comprehensive procedure from initial mapping with the SAT system to the completion of a custom piano tuning, using the LC Spreadsheet as a central tool. The demonstration is intended to illustrate the logical flow of the process and provide insight into each step required for effective piano tuning.
