Who wins on what

Ranked by what users actually praise

Overall Impression

It excels as an atmospheric pad, not a lead instrument. Commenters repeatedly stress that the Mel9 is built for slow chords, pads, and swells rather than fast melodic runs or dense chords. Sticking to diads, triads, root-and-third voicings, and mid-tempo arpeggios brings out its best character, while attempting Bach-like runs or thrash riffs at speed leads to disappointment. Several longtime owners describe finding new sounds for years by working within these constraints.

A compressor and reverb chain is almost mandatory. Many users found the pedal's volume jumps, drone-note cutoffs, and pick-attack noise frustrating until they added a compressor before the Mel9 and reverb or a volume pedal after it. This combination is credited with smoothing dynamics, taming sudden swells, and letting the orchestral and choir voices sound fuller and more natural, especially in acoustic singer-songwriter and looper-based setups.

Voice quality varies a lot by setting and range. Orchestra, strings, cello, and choir settings receive the most praise, especially in their proper frequency ranges, while brass, sax, clarinet and low choir are called weaker or range-sensitive. Several note flute and clarinet sound best played higher on the neck, and playing outside an instrument's natural register causes unnatural, unconvincing tracking regardless of setting.
