Large Delay Changes

When implementing large delay-length changes (by many samples), a useful implementation is to cross-fade from the initial delay line configuration to the new configuration.

• Computation doubled during cross-fade
• Cross-fade should be long enough to sound smooth
• Not a true ``morph'' from one delay length to another, since we do not pass through the intermediate delay lengths.
• A single delay line can be shared such that the cross-fade occurs from one read-pointer (plus associated filtering) to another.
