So basically subtractive plus fm. I'm sure there are some. But I wonder why it's not just common. Anyone know of some?
I mean an LFO that can go at least 20 times higher than the carrier wave. Seems like a very slight change that could really open up potential.

1. Most nowadays FM synths already work like a subtractive one...(with filters etc...)

2. There are already some offering this like i.e. PhasePlant every oscillator can modulate every parameter inside at audiorate...

Anything that’s modular should fit that description

Yes. Massive X can do that for example. Like, you can use an LFO as an additional oscillator. You can do very wild PM stuff with this synth.

Thanks.

The “L” in lfo stands for “low”.
If you take an lfo into audio rates it’s no longer a low frequency oscillator. It is just a standard oscillator.

It’s a bit like asking why there are no 6 foot dwarfs.

...and fm synths are really phase modulation synths. I know what lfo stands for.

Standard synth oscillators are tuned to incoming MIDI pitch, while LFOs are not.

...or maybe there are some internet haters that prevent low frequency oscillators from being fast, there are surely not rational or technical limitations.

One issue I see is LFO tuning - if you have one little knob controlling range from 0.001 Hz to 20 kHz, it's difficult to dial any particular value.

The other may be some fetish for "analog emulation" - if original synth had low frequency range, the new one has this limit as well.

Depends on the synth. Some of mine don’t even have midi and with some you can disable the keyboard/midi control of oscillators.

There actually are technical limitations and rational decisions but it has nothing to do with weather you hate the internet or not.

And yet you ask for one that is high frequency.

Yes,Yamaha DX,etc use phase modulation but there’s still alot of actual fm out there.

Some oscillators (lfo’s and audiorate) have a range switch to make dialling in precise values a bit easier and some have numerical values you can enter.

^ He’s a human adopted by Dwarves. Just like an audiorate lfo is really just an oscillator adopted by the modulation bus.

You did have me thinking “wtf, how’s that even possible” for a minute.

Why not a subtractive synth with LFOs that go to much higher rates?
