Funcbeat samplerate can be undefined at t=0

[Chasyxx]

Discovered this while working on THE[BOX]'s funcbeat cover. Sometimes funebeat's samplerate value can be undefined at t=0, which threw off the snare on my cover, including compilation and page load.

(edit: changed the link to be a bit more dynamic to samplerate and show that this does happen more than once)

Turns out it also happens on Sarpnt's original player: https://bytebeat.ficial.net/#5X6AAD8K0otKS3KU0grzUsuyczP0yjRCdZUqObizEzTCLa1Lc1LSU3LzEtN0VQoySjKL1dQClYoTyxWgIsrKCloK2TmlWgUJeal5OdqaGqZmWhycabmFKcqQI0u0Q/WMjSyMAACVUNrrloA
