High Key Numbers

At very high pitches, the delay-line length used in the string may become too short for the implementation used, especially when using vectorized module signals.^6.5 In this case, good results can be obtained by replacing the filtered-delay-loop string model by a simpler model consisting only of a few parallel, second-order filter sections.
