Hello englala1955,
[Topic moved here.]
Yes -- to add to Mark's reply, please first try working through the steps in that section ("
Performance tuning | Other operating system and computer optimizations and diagnostics" which starts on page 308). For example:
- Make sure that all available motherboard BIOS updates are applied.
- Make sure that all available Windows updates are applied.
- Make sure all available firmware and driver updates for hardware devices are applied, and especially so for audio/MIDI interfaces, the graphics card, and the motherboard. Check on their manufacturers' websites if needed.
- Make sure that all Windows power saving options are disabled, and especially the option relating to putting USB devices to sleep.
- Make sure that Windows drive indexing is disabled for all drives.
- Make sure Windows Superfetch/sysmain is disabled.
- Make sure no other unnecessary applications or processes are running in the background.
- Try running LatencyMon (
https://resplendence.com/latencymon ) when Hauptwerk is running, and see if it reports any problems when the glitches occur.
- In Hauptwerk, on the 'General settings | Audio device and channels' screen in Hauptwerk, make sure that the manufacturer-supplied ASIO driver is selected (as opposed to a DirectSound driver, or a third-party driver). Also set the number of buffers to 1 and the buffer size set to at least 512 and the sample rate to 48 kHz (all of which should be 'safe' values).
- Make sure you aren't over-filling the PC's RAM. As a test, see whether the problem occurs with small sample sets, such as St. Anne's.
Best regards, Martin.
