M! has all the features of the successful scaling slide rule, used the world over by organ builders, experts, and amateurs. In addition, M! offers straight-forward intuitive usage and all the advantages of modern computer programs.

• Easiest diagramming of scalings
• graphically (with mouse or pad).
• calculated (broken scales, addition constants, etc.).
• Comfortable analysis of existing scalings
• numerical input of scalings.
• import of scalings form other programs.
• Clear management of scales
• freely arranged stop list.
• multiple masking of scale curves on the graph.
• simple placement of commentary on the graph.
• Multiple readout possibilities
• graphs of scales in various combinations.
• spreadsheets of all measurements (deviance from mean, diameter, width of mouth, theoretical length, end compensation and much more) for values between C1 and c61 (also selectively, e.g. C-F#).
• export of spreadsheet as CSV
• export of diameter scales as 2D DXF
• copy and paste of spreadsheets (or parts thereof) in text programs.
• printing of scales (graphics and spreadsheet)
• Use as a documentation medium
• M! is available for the most important platforms (Windows and iOS coming soon).
• All documents created with M! can be opened by any of these platforms. The data files are byte compatible.
