“SevenDelay is a stereo delay using 7th order Lagurange interpolated fractional delay. Also 7 times oversampled. Suitable for making sound with actively changing delay time by hand or DAW automation:

– 0.1 ms to 8 s delay time. Parameters are tuned towards short delay.
– All parameters are smoothed.
– Parameter smoothing can be controlled by user.
– Continuous change between normal, inverse, ping-pong and other panning.
– High-pass and all-pass filter for feedback.
– Negative feedback.
– Tempo sync for [1, 1.5, 2, 2.5, …, 7.5, 8]/16 beat.
– An LFO for delay time and all-pass cutoff.”
