SoundStepper Changelog

What's new in SoundStepper 5.4.1.302

Nov 3, 2017
  • Native ASCOM driver, for Telescope and Focuser, no more need LX200 emulation nor TCP/serial redirectors.
  • Implemented some new commands in the protocol, to support the native ASCOM driver.
  • Added the "Instant focus display", which shows the focuser position changes when SoundStepper is in background.
  • Added a timer to effectively defocus controls on main form and allow user to control telescope with keyboard arrows.

New in SoundStepper 5.2 (Nov 24, 2014)

  • New concept of park position for equatorial mounts, enabling to park at celestial pole without problems to recognize the correct position at startup.
  • More indicators in main window (progress bar, pierside indicator).
  • Many bug fixed.

New in SoundStepper 5.1 (Jul 17, 2013)

  • "Pulse/direction" control option added, compatible with commercial drivers.
  • New startup window, showing the previous state and all available options.
  • Dead threads detection.
  • Extra buffers insertion at high speeds, less catastrophic failures.
  • Compatibility with Stellarium (changed angle formats from "documented dialect" to "real dialect").
  • Many bug fixes.

New in SoundStepper 5.0 (Jul 17, 2013)

  • Ability to control altazimuthal mounts.
  • New keyboard interface, for more easy and precise control.
  • Added altaz "sync" control.
  • Motor threads control algorithms was rewrited.
  • New configuration and test interfaces
  • Added joystick interface

New in SoundStepper 4.0 (Jul 17, 2013)

  • Modified the algorithms to use USB Audio devices, supporting DC operation, ensuring better control of motors and releasing the default computer audio output to normal use.
  • Add control for up to 3 motors (RA, Dec and focuser).
  • Added ability to control any type of equatorial mount, and the "sync", "go-to" and "flip" controls.
  • Configuration screen, contain audio operation parameters, mount type and limits.
  • Monitoring and compensating the audio sampling frequency variations, the systems become immune to this changes.
  • The waveform became configurable to improve motor movement linearity, lowering wooble in low-reduction mounts.
  • The screen texts was moved to .ini files, allowing easy translation to any western language.
  • Done the first to English translation. The code was already modified for variable names and comments in English.
  • Project was made available as "public domain" at Sourceforge.net.
  • Implementation of the LX200 protocol, allowing the use of ASCOM driver to control and guide, retiring the obsolete parallel port.
  • Autosave and autorecover last telescope and motor positions (crash recover).
  • Re-elabored this documentation (migrated from README.TXT file to HTML).

New in SoundStepper 3.1 (Jul 17, 2013)

  • Center and find controls added ("Control Box"), using keyboard arrows.
  • Smooth motors acceleration and improved intuitiveness of the controls.
  • Return interrupts are now permitted. Redone the project documentation.

New in SoundStepper 3.0 (Jul 17, 2013)

  • Multi-threaded version, with a dedicated controller thread and another for the user interface.
  • No longer audio gaps. Identical to version 2.0 user interface.
