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.

Midiflow Scales (Audiobus)
This MIDI effect app allows you to filter or remap incoming notes to fit a specific musical scale. It helps prevent incorrect notes, create harmonies, and simplify playing scales using your keyboard.
- Filter out notes outside a scale
- Remap notes to the closest scale note
- Play scales using only white keys
- Select notes manually
- Choose from predefined scales
- Use multiple instances in Audiobus

This MIDI effect app for Audiobus 3 lets you filter out unwanted notes or remap them to a scale. Thin out tracks from a sequencer to create a reduced variation. Prevent wrong notes when playing on a keyboard. Generate harmonies by using the app in combination with Midiflow Transposer. + Filter out "wrong" notes that are outside of a scale + Remap notes to the closest "right" note + Play a scale using the white keys (or all keys) + Pick notes manually + Select from a list of predefined scales (Min/Maj Blue, Ionian, Dorian, ...) + Use multiple instances of this effect in Audiobus NOTE: This app requires Audiobus 3. Insert it into one or more MIDI effect ports to affect the data going through the respective pipelines. SELECT ALLOWED TONES In music theory, a scale is basically a set of tones relative to a root note. Building chords and melodies from a scale identifies its unique sound. The most popular scale might be the ionian scale in C, which is made up of all white keys on the keyboard. The scale of all black and white keys is called the chromatic scale. Midiflow Scales is a note filter and remapper that is optimized for working with scales. The keyboard-style note selector lets you activate notes that should pass the filter and deactivate those that should not go through. You can also select from the list of pre-defined scales. If you select a different root note (default is C), the app will update the selected keys to maintain the scale. So, if you have selected the ionian scale in C, and then change the root note to G, you'll see the F changing to an F#. MOVE NOTES INTO THE SCALE Midiflow Scales can not only mute "wrong" notes, which are notes outside of the scale, but it can also move those notes inside. The selector at the bottom lets you choose between filtering out those notes or remapping them to the nearest note that is part of the scale. If possible, the algorithm assigns the activated notes to the keys of the ionian scale. What sounds complicated actually makes it very easy for you to play different scales just with the white keys, or transform a stream of notes into a completely different scale. PLAY THE SCALE WITH THE WHITE KEYS While the previous remapping methods ("Nearest" and "Filter out") correct incoming data to match a scale, Midiflow Scales can also reorder the notes on the keyboard, so that you can play the scale without thinking about its half tone/full tone steps and the root note: With the "White keys" option, all notes of the scale will be assigned to successive white keys. For example, if you want to play "Min Blue" in E, you then just have to play C, D, E, F, G, A on the keyboard. The option "Chromatic" does the same but with C, C#, D, D#, etc. CREATE VARIATIONS AND SECOND VOICES This note remapper has many applications and is really fun to use. If you have a melody programmed in a sequencer, you can create a bass line by sending the same track through this app and activate only one tone. Experiment with the remapping options explained above to either get bass notes on every melody note, or only when the melody reaches the root note. Thin out tracks by removing some tones to create variations. Or use this simplified version of the track in parallel for a second, layered sound. This is also very useful when playing live with multiple sounds. Audiobus allows you to chain MIDI effects, and doing so with Midiflow Transposer and Midiflow Scales lets you create second voices: First transpose the notes by 4 half-tones and then force them to the ionian scale, for example.
