I read in a discussion that too many MIDI records ( notes ) sent to scene control from a DAW (such as Ableton ) can cause the program to crash. Is this true ?
if in ableton only the codes to the lights are sent through the virtual midi port, the sending speed is about 15-40 bytes! per second, which is actually ridiculously low.
Atention! You must not have a live channel set for playing with this solution, as it supplies the port with a constant stream of values and overwhelms the port.
The transmission speed of the MIDI protocol is standardized at 31,250 bits per second (31.25 kbps). This corresponds to asynchronous serial transmission with precise timing: each byte (8 bits) is framed by a start and stop bit, totaling 10 bits per transmitted byte.
Practical Implications:
The theoretical maximum number of MIDI messages that can be transmitted is approximately 3,125 bytes per second (31,250 bps ÷ 10 bits per byte).
A typical MIDI message (e.g., Note On or Note Off) uses 3 bytes, so the system can handle up to ~1,000 simple messages per second, which is sufficient for most musical applications.
Notes:
The speed is fixed and independent of the physical interface (e.g., 5-pin DIN connectors, USB-MIDI, etc.).
MIDI transmits only control data (e.g., note presses, parameters), not audio signals. The low speed is therefore not a limitation.
