Bug Description

I'm aware you may be currently busy and this bug might be hard to fix completely (let's hope not), but it's a thing that bothers some people nevertheless. As reported by @iyatemu on Discord server, SSG emulation inBamboo Tracker is off, especially at higher pitches, compared to the real chip:
alias.zip - recording showcasing the problem. 0:00 ~ 0:04 is BT, 0:05 onware is the real YM2608 interface. Difference is apparent.

The way to fix this? I'm not sure at all, maybe via #262? (SSG core was also updated).

Thanks for your report. I suspect the use of improper linear resampling to be the cause of the distortion. I'll change to sinc resampling as mentioned in #321 and check the sound.

This issue would have fixed by using blip-buf since b1a6d2e.
