I love going back to old synth plugins just to see what can be done with them. Neon is apparently the oldest VST instrument there is (came with Cubase 3.7 in July 1999), so that's right up my alley. I've given it a go, made a handful of tracks and sounds with it, and here are my thoughts.

The 3 waveforms (tri, saw, sq) ... they could have just made it a plain square.
Being the first.
Woodgrain panel.

Only 5-note polyphony (even though it's supposed to be 16).
Oscillators waveforms are low quality and sound like they have a permanent low-pass filter.
Filter lacks an "Envelope Amount" control.
No individual waveforms for oscillators, or Osc volume mixing control.
Osc2 detune only goes 7 semitones back and forth, so no octave higher/lower possible.
ADSR envelopes are a bit clicky even when turned all the way off
LFO depth (mod wheel) is weak, as well as the pitch bend range is weak.

In summary: It's not good at all. And being old isn't an excuse. Both Model-E (Steinberg) and Pro-Five (Native Instruments) were created before Feb 2000. That's less than a year later. Then Native Instruments came out with FM7 in Feb 2001, which to this day is one of the best FM synth plugins ever made. And Neon could have been better.

It's oscillators are pretty bad. Neon is advertised as having two oscillators, but the only thing you can do is detune Osc2 up or down 7 semitones, not even a full octave... There is no oscillator mixer or individual waveform selection. And that's fine, the real crime here is how horrible the oscillators sound. Look at the output through any analyzer and you'll wonder what happened to the high end. The high frequencies are all filtered out, so instead of rich harmonic square or saw waves, you get these bland waveforms. And they get worse the lower you go. It's almost like they're using a single-cycle .wav file for each oscillator!

The filter is also pretty bad. It's weak and you can barely hear the effect of turning the cutoff down or resonance up. And the filter envelope is hard-coded to react to the "sustain" level as the amount, no "amount" knob to speak of.

Even heavy EQing can hardly save this synth. Give it a shot, and see for yourself. Steinberg still offers it as a free download. It can make borderline acceptable basic sounds thanks to the ADSR envelopes, but even the waveforms of the NES sound better than these do.

Of course the sound doesn't stand-up, it's literally the first VST synth ever.

Respect your elders.

According to Wikipedia, Neon was literally the very first VST synthesizer, not the first software synthesizer but the first one made using the Steinberg VST standard. I don't know how well it compared to the competition in '98 or '99 but the synth is now freeware as part of the Steinberg Classics Pack Vol. 2.

Sound-wise, it's a thick and bland sound, not necessarily bad-- in fact, I'm sure you could imagine places to use it but with such a wide variety of free synths out there, why would you? The timbral variety offered by the Neon is paltry, mostly due to a filter that doesn't filter very much and a hard-to-hear LFO.


  • Historical curiosity.
  • Capable of a count-them-on-one-hand number of appealing sounds.
  • Unbelievably low CPU usage. On my laptop which is from 2008, it used 0.1% of my CPU.


  • Badly implemented skeuomorphic knobs require you to point your mouse in the actual direction you want to turn your knob.
  • Filter and LFO are both difficult to hear.
  • Extremely low timbral variety.

If you're actively looking for an uninspiring synth, you've found one. Otherwise, the value of this VST is extremely limited.

This is one of the earliest VST instruments, if not the earliest of them all. I heard back in 1998 that a friend talked about a synth called Neon that was software, but I didn't believe him. It wasn't until 2001 that I had the chance to test it out on my own when I bought Cubase VST.

Neon is a pretty useful synth for it's era, nowadays almost all analog VST's can produce similar sounds. But the sound in itself is pretty slick and smooth. Good for sturdy synth basses, pads and brass sounds. Not that special as I said but back in the days this was the synth I went to for new fresh sounds. The interface is pretty straight forward, nothing strange here. Featurewise this gives lots to wish for, but for the money what can you really expect? If you can download it from Steinberg then this is worth trying out, but if not... Well there is plenty of other plugins with similar features. I wouldn't lose any sleep over the failed download. So does it beat the plugins with stockpiled SynthEdit components? Yes I have to say because it has a bit phatter sound than most synthedit components can produce.

Some people don't think much of Neon but here's how I see it. It's simple to use encourages people to play around and (maybe) learn something about subtractive synthesis.
Neon lacks in performance features but makes up for it by sounding good and for free sounding good works for me. Capable of good pads, modest leads and pads, not good for Fx and weird, typical analog weirdness.

Pros: good sounding, free, simple but effective editing
Cons: could have been more feature laden, doesn't do many of the fun features associated with subtactive analog (of VA)

It's free with Cubase, maybe even free on Steinberg's site. Worth checking out. Good for meat and potato synth timbres.

"I don't know how well it compared to the competition in '98 or '99""

Compared to e.g. http://www.vintagesynth.com/misc/reality.php it wasn't that great either ;-).

Some great memories of this synth so it has a nostalgia factor... But most of all I seem to remember thinking "DAMNIT, FILTER, OPEN!" because it seemed to be impossible to get the cutoff to go very high at all.

It was mainly used for bass and pads.

the wooden 8-track tape player enclosure makes me moist <3.

In the manual it states "The Neon is polyphonic with up to 16 voices. However, since each added voice consumes CPU power, the maximum polyphony may be limited by the speed of your computer."

However I can only get 5 voices out of it. Is it inaccurately determining modern CPU speeds or did they outright lie all these years? Oh well, it's a piece of crap anyway. The CS40 actually has 8 voices but it's advertised as "polyphonic with up to 6 voices". Nothing but lies.
