Soundplant

Playlist queuing; recording quality improved to 32-bit; 'fade out all sounds' function;
faster sound file loading, decreased cpu usage & other optimizations; universal support for secondary output channels on multichannel devices; many minor improvements and bug fixes

32-bit floating point internal sound mixing adjustable to up to 96 kHz for highest possible sound output quality, making this the best sounding Soundplant ever
256 sounds can be played simultaneously, with up to 12 channels of playback progress displayed in detailed view mode
sound output device selection
reverb, lowpass, resonance, and lfo realtime effects
direct internal recording of Soundplant's output
completely overhauled sound mixing engine now uses the great and lightweight FluidSynth, a solid and battle-tested open source sound engine enabling many of the above improvements
'hold down' mode allows precise control over key releases
redesigned interface with more room for sound names, an enlarged waveform display, and vector graphics for better window stretching
key labels text size setting
customizable key label text
'buffer size', 'interface refresh rate', and 'key glow animation' settings for performance tuning
'background key input startup state' setting
'foreground window on sound trigger' setting
added an 'only on sound trigger' option to the 'select key on key press' setting
added a 'locate file…' option to the alert that appears when loading a keymap and the sound file can't be found in its original location, and improved automatic searching for sound files when loading keymaps
'reload sound from disk' button
improved master volume control offering up to 200% processed amplification
finer individual key pan and volume control and better, smoother fades
smoother realtime pitch shift
onscreen keyboard layout changed to match the now more common layout with smaller return key and backslash on the row above it
RAM or disk loading option for each key no longer available, this is now handled automatically to take advantage of modern system capabilities with more RAM
fade in and out times can be set to 0 to more easily have a key that only fades in or only fades out
64-bit optimizations have been included for systems which support it, speeding up sound loading especially for compressed sounds
improved support for surround sound files containing greater than 2 channels (Soundplant can now play them, but only as mixed down to 2 channels)
increased the 'recent keymaps' dropdown list size to 25 keymaps

Support for virtually all audio file formats in existence; a 'background key detection' mode that allows Soundplant to continue receiving key input even while minimized or hidden; waveform display; detailed playback progress indicators for all channels; precise fading control; randomization settings; first official Mac release after several years in beta
