If you do something like Synthwave or another vintage genre you HAVE to use this synth! It's free, sounds wonderuful vintage and you can load original Yamaha DX7 Patches.
Dexed can read DX7 patches, sounds quite like a DX7, is way easier to program than a DX7 and is completely free of charge. I'd happily pay 10€, if only they could make the GUI a bit better...
DEXED simulates the mighty Yamaha DX7 FM synthesizers of my youth. I still have one. Basically this thing is 98% a real DX7 sound but what you lose in sound quality DEXED makes up for with ease of programmability. While maintining the vintage Yamaha look in their GUI, Digital Suburban have incorporated the best virtual-knob and graphical controls from various popular DX7 midi-patch-creation freeware. This is much easier to program than your DX7, can load up actual DX7 saved patches and is just a joy to screw around with. I still use my DX7 when I want to grunge up an FM sound through a guitar amp or something, but if I want crisp, DI Yamaha sounds I go for DEXED.
no, it's not as powerful as FM8, but my god, as far as softsynths go, this one is 1) FREE and 2) really light on CPU (a few percent at tops on my quad core amd) and sounds amazing. plus there are tons of patches because it's a DX7 in a VST package, and DX7 patches are everywhere on the internet for free. you gotta get this VST. plus if you own a Volca FM (planning on getting this), you can prototype and send your patches here.
