Sunvox... It slices... It dices... (a brief guide to a sample slicing technique in SunVox)
Been playing around with the new interpolator in SunVox, and it works great for sample slicing. So great, I had to share.
-Use "Open In" in AudioShare to import a sample to Sunvox. This will automatically import the sample to SunVox in a Sampler module, ready to connect to the output.
-Use the main menu (upper left) to match the project tempo to the sample tempo.
-In the pattern editor enter C5 (default sample pitch) on every fourth line (or 2nd, or 8th, or whatever). Also enter "07" in the effect column (EE) for each note, which is the "sample offset by percentage" effect.
-In the pattern menu (upper right) choose "select all" to highlight the pattern, then also "enable level drawing" to give you a visual representation as well as the option to quickly adjust by hand, and then finally choose "Interpolate" to open the interpolator.
Navigating the interpolator:
-The top row lets you select the type of curve, ping pong on/off, and step. The step is handy if you only want the curve to apply to every 2nd line, 3rd line, etc.
-On the next row choose the far right option "XXYY" so that values will be entered (for future reference, you can interpolate notes "NN" too, for random melodies, volume level "VV", etc.).
-The next row has 2 sliders for randomizing. When all the way to the left no randomization occurs.
-The interpolate button in the bottom row applies the settings to the highlighted selection of the pattern.
-Another way to adjust values is to use the "apply envelope" button, do this by adjusting the "envelope start" and "envelope end" sliders in the fourth row, and it will apply those values.
-When you tap the interpolate button it will enter values ranging from the top of the highlighted section to the bottom. It's purpose is so that you don't have to enter values by hand. For this example, randomization is required, because there are no values entered as of yet.
-After entering randomization values on the third row and tapping the "interpolate" button you should see values entered in the pattern, visually represented by yellow bars. The bars indicate at what point the sample will begin playback for each line. All the way to the left indicates the beginning, middle (numeric value of 4000) means sample will play back at the 50% point, and far right means you won't hear anything because the sample starts at the end.
-To hand draw in specific values, tap the lock in the upper right. This can be sensitive. Make a mistake? Use the "undo" in the main menu (upper left). Pressing play to hear your changes will automatically lock the pattern for you.
-Drawing in values to the far right (no sample playback) is a quick and easy way to enter note rests.
Getting rid of clicks:
-At this point you've probably run into the problem of hearing clicks, which can be alleviated by adjusting the sample volume envelope. Highlight the sampler module, then tap "edit" in the module properties. From there tap on "envelope" and then "volume". Best way to set up the envelope is a simple attack and decay with three points. Set the initial point at zero, the 2nd point at full volume, and the third point also at zero. Then highlight the 2nd point and choose "sustain" from the menu, so that the sample will sustain at full volume.
Export and variety:
-Exporting patterns is pretty easy, just choose "export" from the main menu (upper left) to save it to a wav file, then choose that same menu option to copy the file to the pasteboard.
-For variety you can use a combination of interpolation and drawing in values by hand as noted above. Whatever section is highlighted will be interpolated, and tapping the unlock button lets you draw values by hand.
-SunVox itself offers quite a bit of options for variety, like effects and modulation. Manual for more details: http://www.warmplace.ru/wiki/sunvox:manual_en
