Volko Audio

Volko Audio has digitally recreated the sounds of the API 500* series with the Q American Series of three plug-ins that offer a combination of high quality sound and modern user interface.

QA, QB and QG compliment each other and eliminate phase and artifact problems that arise when linking together different plug-ins. Their interface is intuitive, user friendly and easy on the eyes, letting you work tirelessly for hours.

The plug-ins are optimized to keep your CPU under low stress, while still maintaining top quality sound output.

Price: $139 each / $299 bundle.
