Uno FM

Uno FM is based on FM synthesis but have a layout similar to old analog models.

Uno FM is no way trying to recreate the classics like DX7 and the likes but to find a little corner of its own with its limited sound capability.

So basically this contains 4 operators: one carrier, three modulators. All 3 modulators share an envelope, and they all modulate the carrier directly. But you can alter the volume and pitch of each modulator. It's not a great design, and it doesn't sound too good either - Yamaha FM sounds quite different.

I would say it's more akin to 2 operators. The Carrier just has one sine wave generator, and the Modulator has 3 sine wave generators. Also, this is 'real' FM, not Yamaha FM which is actually phase modulation. It lacks ratios for pitch. Otherwise I agree! That GUI is ew.

Wow!!...He did it again!!.....It's not a real DX7 but sound alike....It's capabilities are limited, yes, sure, but it's so, so useful....Michael Kastrup made the synth in 2004. I don't mind!!!....Sounds beautiful and dot!!!!
