PT2399 Delay with two Switchable Inputs and Internal LFO

GRITZNER is a short delay with two individual inputs that may be activated alternativley either by hand or with a gate signal. IN A is a standard audio input whereas IN B is a high pass filtered input. Frequencies below 320hz will be filtered out which is quite handy for some delay settings. If the MAN/LFO switch is on the left you can switch between both inputs manually using the A/B MAN switch. If the MAN/LFO switch is in the right position an internal square wave LFO automatically switches between both inputs according to the LFO range set with the help of the LFO potentiometer. Alternatively you may patch an external gate signal (from a sequencer for example) into GATE A/B in order to switch between inputs.

The Delay itself is a classic PT2399 delay with its very special touch and a delay time ranging from 30-190mS. It has manual controls for the Delay Rate (going beyond the ICs operation range), Feedback and Wet. The delay rate can be voltage controlled with an external signal or with the help of an internal LFO. You can choose between a triangle and a square wave LFO and you may attenuate its signal with the LFO ATT attenuator. On top the LFO is resettable via the LFO RST input in order to get delay changes in a rythmical manner. The LFO rate can be adjusted with the LFO potentiometer.

The GRITZNER Delay is a special kind of module that is able to make all sorts of weird delay sounds, from chorus like effects to total destruction of the original signal. There are no boundaries for your crazyness here. Though the two switchable inputs and the LFO reset always make its output fit into a rythmical pattern of your patch.
