Mel-Lofi

Mel-Lofi is a free virtual instrument (ROMpler) for Windows and macOS.

The instrument features recorded Mellotron samples.

You'll find a total of 23 presets spread across 5 main instrument categories. Even though the sounds were edited, they still have that rough and lo-fi sound.

A nice addition to the instrument are the 4 FX layers that can be added to any sound. The layers include radio noise, vinyl, mechanical belt noise, and rain.

You will find the following controls on the rest of the interface: pan, volume, attack, release, reverb, tuning, LFO modulation, and filter cutoffs.
