Adding Loops for MIDI Samplers

Audio files in the WAVE and AIFF formats can contain specialized loop information for MIDI Samplers and software samplers. Acoustica supports this standard and you can add loops and define the base note and fine tuning of the recorded sample.

To add a sample loop, click in the Clip Editor window and create a region where you would like to create a sample loop. Next, choose Add Sampler Loop... from the Edit menu or press the letter "o" key. The Add Sampler Loop dialog box appears:

You can specify either an infinite loop that is repeated until the MIDI note is released or a specific loop count. Acoustica also allows you to crossfade the ending and the beginning of the loop to avoid clicks at the loop edge. You can set the length of the cross fade regions relative to the loop length in percent and choose between constant amplitude and constant power cross fades. Constant amplitude is recommended for tonal sounds whereas constant power usually works better with noisy sounds. The cross fading is performed when you click the Apply buttons and you can undo the last cross fade by clicking the arrow back button.

The information in Global MIDI Sample Settings is not stored for each loop, but are global settings for the complete recording. You can edit these settings when adding loop because loop information and note with fine tuning information is usually required when creating loops for MIDI samplers. However, you can also change these parameters in the Tempo and Key tab of the recording properties under File > Edit Properties....
