Software & Hardware Links
Here are some programs that are useful/fun in combination with Soundplant:
  • Audacity (free x-platform audio editor)
  • Audiomulch (great x-platform realtime effects processor)
  • Bome’s Midi Translator (x-platform, can convert MIDI input to keyboard key hits so you can use a MIDI device with Soundplant)
  • GlovePIE (free Windows only programmable input emulator, can convert input from many devices including MIDI, Wiimote, and joysticks to keyboard key hits so you can use these devices with Soundplant)
  • JoyToKey (Windows only program for converting input from joysticks and other game controllers into keyboard hits so you can use them with Soundplant)
  • FAAST (free Windows only software for Microsoft Kinect, can convert body motion input to keyboard key hits and works well with Soundplant)
  • Virtual Audio Cable (adds a virtual sound device to Windows which you can use to directly route output from one program into another, can be used to internally record or process Soundplant's output)
  • Jack OS X (free, adds a virtual sound device to Mac which you can use to directly route output from one program into another, can be used to internally record or process Soundplant's output)
  • Soundflower (another free Mac utility for routing audio output via a virtual sound device, can be used to internally record or process Soundplant's output)
  • Webcam Zone Trigger (motion detection software that can be set to send keystrokes when motion is detected in different zones of a video feed, can be used to allow real-world actions to trigger sounds with Soundplant)
  • Air Display (allows your tablet or phone to be used as a second monitor for any desktop/laptop with full interactivity, use Soundplant on an iPad, iPhone, or Android device!)
  • MAME (awesome arcade video game emulator, good practice for using the computer keyboard for high intensity input)
  • OSCulator (Mac only, can convert MIDI input as well as input from game controllers and other devices into keyboard key hits)

And some hardware with interesting possibilities for use with Soundplant:
  • Das Keyboard (awesome high-end keyboard which works great with Soundplant, both noticeably increasing triggering speed for high-intensity Soundplant applications like drum pad use as well as enabling "n-key rollover", which means that the keyboard's circuitry allows an unlimited amount of keys to be depressed simultaneously)
  • Fentek Industries Keyboard Control Foot Pedals
  • P.I. Engineering X-keys (custom programmable keypads)
  • The I-PAC (hardware for converting joystick input to key input)
  • Kinesis (interesting key input devices)
  • MaKey MaKey (easy to use invention kit circuit board that can make virtually any object send keyboard key input)

Soundplant 40+ uses the FluidSynth software synthesizer, by way of Antoine Schmitt's FluidXtra. Both projects are open source with full source repositories available at their respective links.

Soundplant is for digital samples, but there are other programs which turn the computer keyboard into a midi keyboard for use with midi software rather than as a direct digital sample triggerer. If this is what you are looking for, try either of these:

Soundplant was developed in Lingo with Adobe Director and uses C++ extensions (Xtras) by Valentin Schmidt, Gary Smith, Antoine Schmitt, and Marmalade.
