Mellow FM

Mellow FM


We usually associate Frequency Modulation with bright, metallic, even harsh tones. Actually, when used sparingly, FM is able to convey very warm sounds.
I created the raw samples with Serum and Dexed, then I applied some processing (tape emulation, pitch wobbling, tremolo etc) for further instability.
Here you’ll find 54 instruments and 26 multis, divided in three categories: arpeggios – featuring the excellent stock arpeggiator script – (ARP), keyboards/pianos (KEY), pads/strings (PAD).
Use the modulation wheel for further modulation and tone shaping.
Special thanks to David Hilowitz for his great tutorials, especially the ones on custom graphics and smart round robin.

Beautiful. Absolutely love the “PAD Ambient FM – Ensemble MW” patch in particular. Could sit and play it for hours. Thank you for making this wonderful instrument.

Picked this up with a couple of other Pianobook packs and I am super impressed. Very musical patches – a joy to play & tweak.

I love this so much – ‘Mellow FM’ is another masterpiece from Francesco. I can’t believe the degree of variety this family of instruments, patches, effects (whatever you choose to call them) offers a composer and sound-designer. I’ve been experimenting a lot with ambient, minimalist and synthwave pieces lately and this is perfect for a touch of Sylvian/Czukay or, as Mike Vasas succinctly says in his review, Eno. I’ve already made a demo using ‘Mellow FM’ but, having used up my quota of pianobook demos for the week, was unable to submit it here. I’m already looking forward to using this in an album-length project I’m planning, in conjunction with Francesco’s ‘WLP – Whole Lotta Pads’. As far as I can tell, ‘Mellow FM’s possibilities are practically endless and you can easily create an entire composition using it alone. Thank you once more, Francesco; you’re a pianobook star.
