Audio pops and crackling indicate that the computer isn't meeting the performance requirements that the plugin or program requires. The majority of performance adjustments will need to be made in the host program (such as a Digital Audio Workstation) but here are additional adjustments that you can make in the ARIA Player and CFX Player plugins as well:
Raising the Buffer Size
- Choose Preferences... from the Tools menu
- Select a larger Buffer Size value (Repeat as necessary until desired performance. A higher number will tend to remedy choppy playback, but may cause more latency when working with a MIDI keyboard.)
- Press OK
Choosing a different Audio Driver API
- Choose Preferences... from the Tools menu
- Select a different Audio Driver API (the best option will vary based on your hardware)
- Press OK
Increasing Max Engine RAM Allocation and Inst. Disk Pre-Caching
- Select the Advanced tab in the CFX Player
- Choose a larger value for either of these settings until desired performance is achieved.
Lowering Polyphony (for CFX Concert Grand and CFX Lite Player only)
- Select the Advanced tab in the CFX Player
- Choose a lower value in the Polyphony setting (The Polyphony setting determines the maximum number of simultaneous samples that can be sounding. A higher Polyphony setting is more RAM and CPU intensive.)
