Starting today, FedDSP will release a brand new plugin every week, with each plugin being free for the first seven days. Morso is the first in line and can be downloaded for free until March 17th.
It is available in VST3, AU, and AAX formats and works on both Windows and macOS. Oh, and this comes one week after Elegante, the developer’s previous release.
On the surface, Morso is a pretty simple distortion pedal you could place in front of your virtual cab, put on your overhead mics, or use for sound design purposes.
The plugin is based on classic 70’s and 80’s circuitry and is meant to beef up your sounds or send your leads into sputtering bouts of fuzziness.
The plugin offers two selectable distortion algorithms with distinct characteristics: Morso and Morsone.
Morso is the fat and bloated boost, while Morsone has more bite, spit, and aggression. Select your desired mode with the switch in the middle of the pedal.
For gain staging, you have input and output sliders, as well as a distortion amount and level control to make tone shaping more flexible.
There is an advanced panel with additional controls that lets you select between mono, dual mono, and stereo configurations. This is a small, yet cool feature you’d might want to use on pads, reverb sends, or some FX buses.
Channel-specific saturation on stereo material can create interesting spatial movement, a sense of widening and liveliness that could come in handy.
Morso also includes a sample-delay function, allowing you to further experiment with phase and width. Remember to check your mix in mono every once in a while to watch out for obnoxious side effects.
There’s also a polarity switch and a set of filters, as well as a mix control to blend in your dry signal.
The low-pass and high-pass filters cover a range from 20Hz to 20.000kHz and can drastically change the plugin’s action. There’s also an option to put the filter before or after the distortion stage, which is a nice feature.
Morso boasts a limiter to prevent clipping at the output stage with two different modes: “safe” and “aggro“.
Safe is the transparent alternative, while aggro reacts harder and faster to peaks.
One of the biggest selling points with a plugin like this is its CPU effectiveness and zero-latency, which makes it a good candidate for tracking, not just production and mixing after the fact.
After all, trying to shred hard riffs with latency is pretty much begging for a miserable existence unless your view on life is Camus-coded. One must imagine the bedroom producer happy.
And by the way, if you’re more of a distortion connoisseur, I urge you to check out the new Black Diamond Distortion by Aspen Instruments. It can analyze and emulate distortion, making it a game-changer for both your production and your wallet.
