Echo Cat

Echo Cat is a tape echo audio plugin. It faithfully recreates the sound and behaviour of the Copicat delay, which was introduced in the 60s and quickly become one of the world most famous tape echos of all time.

Main

In the main section you can see a representation of the orignal Copicat with the record and erase heads, and the three playback heads. You can also see the tape loop that spins continuously. On the top you have the navigation tabs and on the bottom you can see the commonly most used parameters.

Heads

Each head can be controlled in great detail. You can either have it time synced to the tempo of your host or you can set the time freely in milliseconds. With volume, pan and LP/HP filters for each head. On the left you can see that there are three led indicators which show you if there is signal on the selected head.

Tape

Control the sound of the tape loop. Includes mono/stereo hiss, artifacts (or cat-ifacts) containing wow and flutter for recreating the fluctuations on the tape speed, tape age with asperity noise and erasures, and signal loss which is random high frequency compression. The "Loop Gap" parameter mimics the tape loop joint, where the tape is physically looped.

Motor

In the "Motor" section you can find control over HUM (low frequency noise produced by electric current). There was a Copicat model in the 70s that featured Varispeed, with which you could control the speed of the motor at will. With Echo Cat you can also modulate the Varispeed amount using a LFO.

Master

Lower the volume of the wet signal when the dry signal is present using Ducking and don't let the delay signal get in the way of the main signal. Apply filters outside the feedback loop. Control the mid and side volumes separately. Make Echo Cat mono, stereo or fake stereo with a 5ms delay only in the right channel.
