SPIRITUS SANCTUS 2 (2013) for realtime Android Csound Arthur B. Hunkins - arthunkins.com - abhunkin@uncg.edu In the beginning God created the heaven and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters. And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. Gen 1:1-2, 2:7 SPIRITUS SANCTUS 2 is a Csound file (.csd) designed to be performed by the Android Csound app. This app is known as CsoundApp[-xxx].apk (Csound5) or Csound6.apk, and requires Android OS 2.3 or higher. The app is downloadable from http://sourceforge.net/projects/csound/files/csound5/Android/ or its neighboring csound6[.xx] directories (as Csound6.apk). Spiritus Sanctus 2 is a meditative sonic environment - a slightly simplified version of the composer's SPIRITUS SANCTUS 2 for Csound5/6 (2013). (The latter work can also be found at http://www.arthunkins.com, accompanied by an explanatory .htm file. Both are similar to the composer's original SPIRITUS SANCTUS, including its Android version; also see website.) There are two ways of preparing for performance, depending on whether or not a computer is available. (Preparation is simpler if you have a computer.) With a computer: 1) Either download and install one of the Csound.apk's mentioned above to your Android device, or download it to your computer, copy it via thumb drive or USB cable to your device (Download folder) and install it. 2) Download SpiritusSanctus2Android.zip to your computer (if you haven't already) and unzip it, then copy SpiritusSanctus2Android.csd via thumb drive or USB cable to a folder (perhaps the Music folder or a new Csound folder) on your device. Without a computer: 1) Download and install your selected Csound.apk to your Android device. 2) Unless already installed, download and install the AndroZip File Manager app from play.google.com . (Note: the WinZip app does not extract zip archives!) 3) Directly download SpiritusSanctus2Android.zip to your device and use AndroZip to extract the archive to a folder of your choice (perhaps the Music folder or a new Csound folder). After installing the app and copying SpiritusSanctus2Android.csd to your device, run CSD Player (Csound 6) and Browse to (Open) this .csd and select it. SLIDERS: Slider 1 controls the combined volume of tone 1 and tone 2. (Tones 1 and 2 are identical, but slightly detuned - causing beats.) Slider 2 is the primary timbre control for tone 1. Slider 3 is the secondary timbre control for tone 1. Note: secondary timbre control only works when primary control is raised (it is fully active only at maximum primary setting). Slider 4 is the primary timbre control for tone 2. Slider 5 is the secondary timbre control for tone 2 (see note above for slider 3). BUTTONS: Buttons 1 - 5 select the base harmonic for combined tones 1 and 2. The available base harmonics are harmonics 4 through 8. Default = harmonic 4 (button 1). TRACKPAD: Both trackpad parameters (x and y) control beat frequency. The x axis determines basic beat speed; the y axis the amount of random movement added to the basic speed. When the finger is lifted, values selected by tapping or dragging are "held" until a new value is chosen. Both parameters are influenced by the particular base frequency selected (buttons 1 - 5). GENERAL ADVICE Note that only one control can be operated at a time. Prior to START, leave all controls at zero or default. After START, make different initial button, trackpad and slider 2-5 selections if desired. Slider 1 should only be moved after any other selections have been activated. In case of audio glitches, reduce the value of sr (Sample Rate) in any text editor (it is toward the top of SpiritusSanctus2Android.csd, which is a simple text file). Set sr progressively to 32000, 22050, 11025 or 8000 until glitching disappears. When left to run unabated, performance will expire in one hour.
