    "AudioSynthWavetable" project, HELP

    Hello, I'm new here.

    I want to set up this project, can someone fix me the electrical connection scheme to teensy?

    Another question: Has anyone set up this project yet?

    Last question: Is there any video of this synth on youtube?

    Thank you

    It runs on the normal Teensy 3.x + audio shield.

    Most of that project was developed using this hardware:

    Hello, PaulStoffrege

    I have a NEW question:

    Are the samples of musical instruments stored in the internal flash of the teensy?

    Or are they stored on the SD card?

    If they are stored on the SD card, which files should I save to the SD card?

    Thank you

    Yes, stored in flash memory. There's a python-based utility for converting sf2 to C language arrays to include in your code.

    I'm glad for the quick return, PaulStoffrege!

    I understood perfectly, Paul. Thus the instrument samples are stored in the teensy flash ok, this fact leads to the limitation of samples stored in the flash because of their size limited to 256kbytes.

    I have questions that I would like help with!

    - Is it possible to play these samples of instruments to the SD card?
    - Is the MIDI in teensy serial command made by the serial RX or is it done by USB?
    - Is it possible to use the external flash memory w25f128fv or 23lv1024 to store instrument samples? How to do this?

    I'm reading the Manual Workshop.pdf, made by paul, congratulations, very good! I'm following every step to succeed with teensy.

    My goal, Paul, is to create a MiDi synthetizor, with all 127 samples of musical instruments.
    Is this possible with teensy 3.2 or 3.6?

    I really liked your project and want to dig deeper and become a good teensy programmer, congratulations.

    Thank you
