Hello Pharny,
(I assume you meant to type 'i7', since an i8 CPU doesn't exist to my knowledge.)
If you're using multi-channel audio, then perhaps your audio device has changed the channels it presents, resulting in some pipes going to the wrong audio device channels.
Please try:
- Reboot the PC. Wait a minute or so to make sure that Windows and all of the devices have had ample time to finish booting fully before launching Hauptwerk.
- Verify that you have the intended audio device and channels selected on the 'General settings | Audio device ...' screen.
- Load the relevant sample set, and see whether you can still reproduce the problem. Assuming so:
- Still with the relevant sample set loaded, see whether you can reproduce the problem with just one of the relevant stops drawn (so as to eliminate any possibility of it being related to the CPU or polyphony being overloaded). Assuming so:
- Try re-loading the organ via 'Organ | Load organ, adjusting ...' and just click OK (without changing any options), so as to ensure that the sample set cache gets regenerated, in case it has become corrupted somehow. Assuming you can still reproduce the problem:
- See whether you can reproduce the problem (with just one of the relevant stops drawn) by simply clicking on the virtual keys, so as to try to eliminate MIDI. If so:
- Exit Hauptwerk, and re-launch it via one of the other 'Hauptwerk (alt config N)' configurations. Use 'File | Revert all settings to factory defaults' within that configuration, OK, then exit, then re-launch that same configuration. Select your audio and MIDI devices when prompted, but don't change any other settings from their defaults. Load the relevant sample set, leaving all settings at their defaults (and don't auto-detect anything yet), then and see whether you can still reproduce the problem with any stops by simply clicking on the keys. If all seems well, auto-detect your MIDI keyboards and see whether you can then reproduce it. Does it exhibit the problem?
