    I'm not actually sure.
    My intention is to monitor each of the 8 multiplexer pins. Maybe I do need a separate Bounce object per pin.

    UPDATE:

    Almost a month ago I added 5v Zener Diodes in parallel with the Piezo sensors and it seems to have fixed my issue. Teensy has not lost connection with Pure Data since.

  6. Bounce & Bounce2 Objects with Multiplexer 74HCT4051 / 4051

    I have a MIDI project using switches, potentiometers and piezo-electrics paired with Teensy-LC. Things are going well.
    I am using 74HCT4051 multiplexers to read these components, and I have had...

    You can read more about the 4051 mux here on arduino's site.
    Also, PJRC has a blurb about using the 4051 on the same MIDI page where your thread is linked.

    The mux allows you to sum 8...

    adrian,

    Thanks and don't mention it!

    The schmitt triggers would probably be perfect for my set up.
    But I think I have a greater need to utilize my 4051 mux's, which will limit the piezo...

    Wow, that's a game changer.
    I have 4 4051's. Using the 4051's could reduce the whole system down to 1 Teensy. I'm not sure why I originally gave up on the 4051.
    Probably limited knowledge of...

    I am definitely going to give these a shot. After using the current set up a bit, I think it'd be wiser to construct a 3rd Teensy unit, specifically for the drummer. I'll test the op-amps out and...

    We get compared to a lot of metal bands. The purpose of this whole MIDI system is to cue audio samples of different machinery I've recorded.



    I think FSR might work OK for this project too, but...

    Thanks! It was valuable research to this project. I have had a hard time finding o-scope data for piezo-electrics. Especially piezo's used in DIY MIDI drum projects, hopefully others can find it...

    Xenomar, thanks for your reply.

    Last night I stayed late at work to use the scope. I took several readings with different circuits.
    See the attached pdf.

  14. Connectivity Issue: Teensy 2.0 MIDI Drum Triggers (Piezo) - Pure Data - MobMuPlat

    Hello PJRC Community,

    I have been spending the past few months building a .WAV sample play-back system for my band / tinkering interests.
    The .WAV files are played using Pure Data....
