What version of Finale and what computer Operating System and version do you use?

How does the playback lag? Is the tempo uneven? Does it stop and start? Does it stop and not start? The more you tell us, the better we can understand.

via Google Translate:

¿Qué versión de Finale y qué sistema operativo y versión de computadora usas? ¿Cómo se retrasa la reproducción? ¿El tempo es desigual? ¿Se detiene y arranca? ¿Se detiene y no arranca? Cuanto más nos digas, mejor podremos entender.

Trabajo con Finale 27, mi sistema operativo es un  MacOS  MacBook Pro (Retina, 15-inch, Late 2013) la reproducción se va trabando pero avanza igual, de manera que no es claro lo que suena, así es ,el tiempo es desigual. no se detiene y arranca sino que, es escuchar algo entrecortado y no respetando la escritura.

I work with Finale 27, my operating system is a MacOS MacBook Pro (Retina, 15-inch, Late 2013) the playback gets stuck but it progresses the same, so it is not clear what it sounds like, that's right, the time is uneven. it does not stop and start, but rather, it is listening to something choppy and not respecting the writing.

--------------------------------------------

If tempo is uneven, one thing to try would be to Select All and use Edit > Clear Selected Items to clear MIDI Tempo Changes.

The other thing to try is to give yourself a larger buffer size via MIDI/Audio > Device Setup > Audio Setup.

Hola, no me funcionan las dos opciones que me das
