TouchAmp -  A Cost-Effective Touchscreen Interface for Winamp

GPL'd Source Code Now Available!

Thanks for all your great emails and suggestions since the 1st release.  I'd be delighted if some skilled developers contributed to this project.  Some popular feature requests have been: USB/Bluetooth/Wifi connectivity for more recent Palm PDAs.

• Controls Winamp with legacy (virtually free) Palm Pilot hardware - no monitor/keyboard/mouse required in listening room
• Does not require using (and losing) a stylus!
• Enables building music servers with unlimited storage space and almost any audio format

Download TouchAmp Beta v0.94 (zipped Palm PRC file, Winamp DLL, Readme and GPL'd source code 4.4MB)

• Edits Winamp playlist song order with a single touch
• Supports browsing the music library's file-system directory tree
• Quickly scrolls through playlist and library screens with single touch strokes or hard-key control
• Directly accesses Winamp media library to provide fast music library searches
• Supports ID3 tags or defaults to filename if ID3 tag not present
• Maps Palm hard keys for convenient control (no need to power-up Palm) of volume, play/pause, next track 
• Maps Palm soft icons for backlight control, search, song properties and extended touch-button menu
• Displays track progress/elapsed time, currently playing song title
• Double-tap on song item in list plays song
• Single touch of play time indicator toggles track progress/elapsed display mode
• Single touch of currently playing song title quickly scrolls playlist to that song

Minimum Requirements

• Palm Pilot or Handspring Visor (OS3.0'ish) incl. serial port cradle 
• Latest version of Winamp 
• Runs optimally when library files include ID3 tags and after Winamp's has scanned music library
