On Windows the driver latency is configurable, so that you can optimize for performance. The Apogee Groove Control Panel is accessible from: All Programs-Apogee-Apogee Groove Driver
Under Buffer Settings here are 2 separate drop downs:
- USB Streaming Mode latency
- ASIO buffer size if you're using ASIO.
The two settings are related, and the control panel will warn you if you try to select an ASIO buffer size that too small for your USB latency setting. The minimum usable buffer setting will vary based on available processing power and other drivers installed. This is something the user may have to experiment with to find the lowest setting that works for them, similar to selecting the buffer size within a DAW.
