Sample Alchemy play modes in Logic Pro for iPad
There are five play modes, each providing a different way to play back the sample. You can tap the Classic, Loop, Scrub, Bow, and Arp buttons to determine the play mode.
Classic button: Select Classic mode to play a sample from beginning to end. Sample playback begins from the handle point and finishes at the end of the sample. This mode is great for playing a sample in a conventional manner. In this mode, the first source parameter (Playback Speed) determines the sample playback speed.
Loop button: Select Loop mode to loop between two points within a sample. In this mode, playback starts from the defined start point, playing to the defined loop end position, then skips to the start point and repeats. These positions are set on the sample using the source handle and source handle end point. You can also place the handle after the loop end point to play the sample in reverse, and move the entire audio section between these markers by dragging the bar between the loop start and end points. In this mode, the first source parameter (Loop Speed) determines the sample playback speed. Set the playback speed of each loop on each source independently to create more dynamic sounds. This mode is ideal for manipulating musical phrases and looped, rhythmic material. For instance, it lets you play particular sections of a waveform and repeat them as the basis for a new rhythmic sound.
Scrub button: Select Scrub mode to play the sample at the touch point and in unison with up to four sources. Play the sample at the position you touch on the waveform, or scrub through the waveform as you touch and move source handles. Up to four sources can be heard simultaneously, depending on how many have been turned on. Scrub mode is great for selecting precise points of the sample and playing all sources in unison for VA synthesizer–style sounds or scrubbing through a sample waveform like a tape machine. In this mode, the first source parameter (Scrub Jitter) determines how much random movement is applied to the handle position for playback. This can be useful for creating a unison-like effect.
Bow button: Select Bow mode to play the sample at each handle position with the bow action mechanism used to play stringed instruments. The up-and-down motion of a bow is replicated to play the sample sources. The up motion plays the sample normally, and the down bow plays the sample in reverse. Up to four sources can be heard simultaneously, depending on how many have been turned on. Bow mode is great for selecting precise points of the sample and playing them back and forth in unison. In this mode, the first source parameter (Bow rate) determines the speed of the bow action. The speed of the bow action can also be synced to the tempo of your project using the Sync button.
Arp button: Select Arp mode to generate repeating patterns of notes that trigger different sections of the sample to create intricate sequences based on the notes played in real time or from a MIDI region. In this mode, the first source parameter (Arp Speed) determines the rate of the arpeggiator. The rate of the arpeggiation is automatically synced to the tempo of your project.
