that doesn't make much sense...

the maximum lossless compression ratio is upper bounded by the entropy of the signals (according to the Shannon theorem). A sound designer has no influence on the ratio. Lossless compression does NOT influence the quality of the decoded audio.

Lossy algorithms such as MPEG-1 layer 3 can use any bit rate set by the user. The lower the bit rate, the higher the loss, and the lower the quality. That's why variable bit-rate exists: the bit rate is set to have a fixed quality rather than a fixed bit rate (thus constantly adapted).

If a sound designer can control the quality of a set of samples, this means that the compression algorithm has a parameterizable quality, and by definition is hence lossy (otherwise the quality would simply always be perfect).

In the motifator forum there are also comments of users that can clearly hear lossy coding artifacts in some samples.
