Does an MP2-encoded bank have a locked sample rate? I’ve been trying to use the sample rate optimization feature while using MP2 compression and haven’t gotten the size to budge. I’ve also tried to resampling my source data from 44.1kHz to 22kHz with the same result; no additional space savings. This seems a little odd, unless I’m misunderstanding how the bank compression is working.

I’m using Designer 1.07.11.

When you adjust compression quality you are adjusting bitrate.
Sample rate has nothing to do with bitrate, once you have a quality/bitrate setting selected. Ie 128kbps is still 128kbps regardless of the sample rate.
Lower sample rates just give you the ability to lower the compression quality without much audible difference. (ie it doesnt have to encode 11khz of spectrum if you change from 44khz sound to 22khz sound).
