some general troubleshooting tips:
Check Settings in Serato Sample:
Make sure that there isn't a specific setting within Serato Sample that governs sustain behavior. Check the user manual or settings/preferences within Serato Sample to see if there are any options related to sustain pedal functionality.
MIDI Mapping:
Ensure that your sustain pedal is properly mapped to the sustain function in Serato Sample. Check the MIDI mapping settings in the software and make sure the sustain pedal is assigned to the correct parameter.
Compatibility:
Verify that your MIDI controller and sustain pedal are fully compatible with Serato Sample. Check the Serato Sample documentation or support resources to see if there are any known compatibility issues with your specific hardware. I'd faced this when I was working with the
mbwhatsking.com, but now solved this.
Trial with Other Samples:
Test the sustain pedal with different one-shot samples in Serato Sample. This can help determine if the issue is specific to the sample you're using or if it's a more general problem.
