StringBand Manager Software

A program for computing instrumental string configurations. Researched and written by Joseph Jourdain, this software is used to analyze, plan or reconstruct a stringband using any combination of string material.


The length, tension, diameter or wrap diameter of any monofilament or wrapped string with or without bedding in any combination of Nylon, Fibre, Gut, Copper, Brass, Bronze, Steel, Silver, Gold or user defined material.


Using monofilament, design & configure a theoretical curve & stringband up to 99 strings, chromatic or diatonic scale.


(New features are printed in bold)

- Choose Imperial or Metric Units for your calculations

- Automatic conversion from Imperial Units to Metric & vice versa

- Save, Reload, Edit, Graph, Print data file

- Global, and local editing, no data retyping for kept variables

- Graph all string variables including the Harp Curve

- New file selector, duplicate file, edit file header

- Fast data entry method, scroll data up or down

- Tools menu available while a file is open

- Fibre core and Bedding Table in Imperial or Metric Units

- Automatic frequency entry for notes

- Keep track of accumulated tension during calculations

- Compute complete string statistic including impedance

- 26 pages of documentation on disk, also available on screen

- Stringing tutorial for beginners, more Sample data files

- Menu driven program, no computer experience necessary

StringBand Manager - Harp curve graph


System required: IBM PC XT or higher with graphic capability. MSDOS, 720 K disk or higher (5.25 or 3.5). Run under MSDOS, Windows 3.1/ 95/98/XP 32 bit version.

Also runs in a "Virtual Machine" such as VM Virtualbox from Oracle, see below.  


First copy the directory COPYSBM4 on your main hard drive from the CD. This will be your working directory. All the files you need to run the program are there and this is where your working file will be saved. SBM runs only in Windows XP or 7 in 32 bit version. Does not work in 64 bit version. A spare older laptop is good for that. To do this:

- Open Windows 
- Select File Explorer
- Go to your CD/DVD drive and select COPYSBM4 directory, then paste it to your hard drive

 To run SBM in Windows:

- Open File Explorer
- Go to the directory where you copied the SBM files
- Select SBM4.EXE 
- Press Enter twice
- There you are. SBM4 should be loaded now.

You can also make a shortcut icon for that program if you wish to load it directly from the Desktop using standard Windows methods.


It is possible to run SBM in Windows 10 only if you use a Virtual Machine program such as provided by Oracle "VM VisualBox". Free download from Oracle with good tutorial. 

It is a computer simulator program that creates a computer inside your computer (you can have as many as you want in one computer if your have enough processors and memory) and you choose the hardware you want (8 bit, 16 bit, 32 bit, or 64 bit) and the operation software, Lunix, Apple, all versions of Windows. It is pretty good and this is what I use for my older data modeling software.

It is not too hard to do but it requires some learning about using and setting up a VisualBox from Oracle. Here is a screen shot of my machine. Main computer is Windows 10, VirtualBox running XP 32 bit, XP running MS DOS 8 bit program SBM.
