Liquid4PRE has 99 program and channel slots each, which allow you to save your preferred settings and pre-amp combinations. A program memory stores the entire settings in the device (all four channels, just like all system settings) to be used individually and at different workstations.
A channel memory stores the respective settings of each channel, which can also be transferred to other channels. Both program and channel memory can also be stored and loaded via the Liquid4 Control software. This allows you to occupy more than 99 memory spaces on your computer and use these settings on multiple devices.
