SampleWiz was awarded Music Making App of the Year for 2011 by the Music Industries Association! Capture your sonic universe! Listen… Record… Create… Jordan says: In creating this instrument I wanted to create something that would appeal to the sonic explorer in all of us. Creating a sampler for iOS devices has allowed us to push the boundaries of traditional sampling instruments. From playing a selection of my signature sounds on the SampleWiz keyboard (JR lead anyone?) to getting up close and personal with sounds by playing directly on the waveform screen, our mission was to blow your mind, put a smile on your face, and expand your creativity. In creating SampleWiz, we have created partnerships with leading sound developers in addition to my personally selected onboard presets. "Inspiring! Just when you thought nothing could be new in the world of sampling, along comes SampleWiz to fire up the neurons of our creativity in new ways. I love the the new realtime interactive noises I can get by 'touching the sound'...the crazy and unique stuff you can do with it is really expressive and fresh!" - Eric Persing, Founder of Spectrasonics "SampleWiz gets you playing instantly, and if you like to sample, there's no quicker or more fun way to go from recording to playing your own samples. Amazing controls, easy to understand yet deep enough to let you create musical voices! And it comes with a library of great sounds from Jordan Rudess. SampleWiz is a wiz if ever there was!" - David Mash, VP of Technology and Education, Berklee College of Music We have poured our hearts and minds into this and driven our families, bandmates, and friends insane by sampling everything that moves. I hope you enjoy this very expressive and wild music app creation! *Choose from three different sampling modes: classic, granular, and modern. *Classic - the traditional method of sampling where the sound will speed up and slow down as you go higher or lower than the recorded pitch. *Granular - Wizdom Music's own take on a granular synthesis engine. Adjust grain size and speed while the entire range of notes maintain the same speed. *Modern - explore new sampling possibilities using Dirac technology to allow formants and time to be adjusted automatically over a device-selected range. *Up to 10 seconds per sample. *Jordan Rudess presets from his private collection. *Resample anything that you play on the playing surface to create all new samples derived from your existing presets! *Three playing surface modes allow you to play on the keyboard, wave-edit screen, and the ADSR window. *Wizdom Music's Advanced Pitch Rounding for initial attack as well as after a slide. *Every note you play is an independent event allowing powerful, expressive control of pitch and amplitude. *Finger vibrato effect allows you to use vibrato even when pitch lock is activated! *Unique visuals for each sampling mode. A glow tracks your fingers and respond to the amount of amplitude of every note you play. *Choose from many different scales and customize your own. *Play your samples forward or reverse! *Looping options include standard looping as well as back-and-forth looping. *Allows trimming of samples. *Unique visualization of the amplitude envelope on the ADSR page. *FX include delay with a choice of tap-tempo, BPM, and seconds control over the rate. *Have two keyboards on the screen, each with its own range and scale! *Unique hold mode where every held note can be in a different synthesis mode! *Share your presets with friends by mailing them as SampleWiz files or standard audio files. *Play directly on the waveform and hear the audio that is right under your finger. Slide each finger separately in any direction to change pitch and position in the sample. *MAPI AudioCopy/AudioPaste allows sharing of audio with top audio apps. *Load your own audio files with iTunes file sharing. *Onboard help screens explain every parameter.
