The multi-band delay machine FDELAY is an exciting tool for sound design and loop manipulation in realtime. In contrast to the delay machines you're used to FDELAY splits the frequency spectrum of the input signal into 27 bands and applies a separate delay unit to each band. The delay times can be synchronized to the host tempo generating nearly infinite rhythmical and sonic variations of the input signal.
