In addition to working with the impulse responses included with REVerence, you can import your own impulse responses and save them as programs or presets. WAVE and AIFF files with a mono, stereo, true-stereo, or multi-channel (up to 5.0) configuration are supported. If a multi-channel file contains an LFE channel, this channel is ignored.
In Dorico, REVerence always uses a stereo channel width. When importing impulse response files with more than 2 channels, the plug-in only reads as many channels as needed. When importing mono impulse response files, REVerence uses the mono signal for both stereo channels.
