Here are effects chain files for some of the multi-band processing setups described in this month's Reaper workshop. Before you load them into a track, though, first click the track's I/O button to check that it has the necessary six track channels. If not, then change this using the drop-down menu. Once this is done, click the track's 'FX' button to take you to the effects window and hit Shift+Insert to insert the downloaded effects chain file.
MultibandReaComp.RfxChain
This is a multi-band dynamics setup using three instances of Reaper's built-in ReaComp compressor. The compressors are set as you might use them for moderate detail enhancement of a stereo submix or other mixed signal. The compressors are all set with 6dB soft knees and 1.2:1 ratios, but the compression speed and detector peak-sensitivity both increase for the upper bands. Adjust the input level and/or the ReaComp thresholds to control the depth of the gain reduction.
MultibandNonlinear.RfxChain
Here I've used three instances of Reaper's built-in Jesusonic Nonlinear plug-in to generate independent saturation over three frequency bands. Adjust the input level and Nonlinear Saturation controls to taste.
MultibandGClip.RfxChain
This is another multi-band saturation setup, this time using GVST's freeware GClip VST plug-in (available from www.gvst.co.uk). I use GClip a lot because it allows a good deal of control over the severity of its clipping curve; here I've set it to the softest setting, for more of a saturation sound, but I'll often use it for straight digital-style clipping too. Again, this setup's sound will vary depending on the input level.
MultibandRubytube.RfxChain
Silverspike's Rubytube (available from www.silverspike.com) is one of my favourite little valve simulators and, in this effects chain, I've used three instances of it to create a multi-band 'warmth' processor. To adjust the impact of the added valve harmonics, vary the overall input level or the Rubytube Shape controls. Bear in mind, though, that the latter also adjusts the overall level of the processed audio, so you'll need to compensate for this with the Output control in each instance.
