Twenty-two free Windows programs that I've written as a hobby over the past 11 years:

USAPhotoMaps 2.77 downloads USGS aerial photo and topo map data from Microsoft's free TerraServer website,
saves it on your hard drive, and creates maps with GPS accuracy. You can:

  • Scroll and zoom
  • See latitude/longitude
  • See USGS Landmarks
  • See TIGER/Line streets
  • See elevation and contour lines
  • Add waypoints, routes, and text
  • Go to any address, populated place, USGS landmark, or lat/lon in the U.S.A.
  • Transfer waypoints, tracks, and routes to and from most GPS receivers
  • Receive/Transmit/Show Ham Radio APRS locations, messages, etc.
  • See your GPS location
  • And much more...

    PianoRollComposer 2.39 is a MIDI sequencer for composing and playing MIDI music.

  • It uses the standard treble and bass clef staffs. Notes are displayed in the piano roll format, so it shows music with absolute accuracy.
  • Notes are entered directly on the staffs, and you can edit each note to give it the exact characteristics you want.
  • You can use all 128 MIDI instruments and 61 [extended] MIDI percussion instruments. Windows will play them all.
  • Up to 15 different instruments can show and play at the same time (think orchestra).
  • If you have a MIDI keyboard, you can play and record any instrument with it, and you can add to existing music with it.
  • The music created with PianoRollComposer can be played by any MIDI player, and can be shown in standard music notation.
  • PianoRollComposer can play and display any MIDI music.
  • And now it can Record To, Play, and Merge WAVE files (think vocals).
  • PianoRollComposer has enough bells and whistles to write any kind of music. Even ringtones.

    SimplePiano 1.16 is an aid for anyone learning to play piano and read music.
    It uses Maestro fonts (that are installed with the program) to show the notes played on the treble and bass clef staffs.
    The notes played are also highlighted on a 60-key on-screen piano keyboard.
    You can play it using the keyboard, the mouse, or a MIDI keyboard (I recommend the M-Audio Keystation 61es).
    The Circle of Fifths can be displayed, and when a key in it is selected, that key's signature is shown on the staffs.
    Any of the eight most-used chords can be selected and played by playing the chord's root key. Chord inversions can also be selected.
    A random note reading exercise is included.
