Code for testing overflows with sending/receiving sysex messages in FL Studio.

1. Create a virtual MIDI port by using a tool such as loopMIDI

2. git clone the project

3. Install the Poetry build system to install project dependencies.

4. Install dependencies by running poetry install

5. Install the FL Studio script by running poetry run python install_script.py

6. Launch FL Studio and assign a port.

7. Launch the sender script by running poetry run python send.py

8. In another terminal, launch the receiver script by running poetry run python receive.py.

Enter the name of your virtual MIDI port (including the number from the displayed port names) to connect to the port.

Follow the prompts to send messages from the send script.

Whenever a message is sent on the port, it will be reported in both the script output and the receiver script.

To send a message from FL Studio, call send_msg(data_length).

• Messages with a length <= 1024 bytes work correctly.

• Messages with a length > 1024 bytes are split into two messages by FL Studio, and are not displayed by the receive script (possibly a similar bug in the rtmidi library? Will investigate).

• Messages with a length that is too large cause FL Studio to either freeze or immediately crash. A length of 1500 did this for me, but I couldn't find a specific value where it starts happening.
