MIDI drum pressure to pulse width

Click For Summary
SUMMARY

The discussion focuses on converting pressure sensed by a piezo sensor into pulse width for a MIDI drum project. The user seeks a method to implement a presettable offset level that determines when the output pulse is generated. A suggested solution involves using a simple resistor-capacitor (RC) circuit connected to a comparator to achieve this conversion effectively.

PREREQUISITES
  • Understanding of MIDI protocol and its applications in electronic instruments.
  • Knowledge of piezoelectric sensors and their signal characteristics.
  • Familiarity with basic electronic components, specifically resistors and capacitors.
  • Experience with comparators and their role in signal processing.
NEXT STEPS
  • Research how to design an RC circuit for signal conditioning.
  • Learn about comparator circuits and their applications in pulse width modulation.
  • Explore MIDI signal processing techniques for drum applications.
  • Investigate methods for calibrating piezo sensors to optimize pressure sensitivity.
USEFUL FOR

Electronics hobbyists, MIDI instrument developers, and anyone interested in sensor-based signal processing for musical applications.

Dear All,
I am making a MIDI Drum project.
I want to convert the pressure sensed by piezo into pulse width with presetable setting to shift the offset level above which the output pulse will be generated.
If you have any other idea to convert pressure to pulse width kindly let me know.
Thanks in advance.

How about a simple RC into a comparator?
