If you set your DAW to 96 kHz, there is not aliasing at all in Sylenth.
I never considered this as a means for quality, I'm not sure it's even possible in my DAW (Ableton). Could you elaborate?

But in my view there is no reason to go beyond 3 or 4 waves per osc, more waves don't really add anything.
Why are they there then?

No, I can't elaborate, all I can say that at 96 kHz I hear no aliasing or other undesirable artifacts at all.

I have no idea why there are up to 8 waves per osc. But when I have a sound and gradually change the number of waves from 1 to 8, I only hear a change in sound character up to 3 or 4 waves, beyond that only the volume seems to increase which can be achieved via the volume sliders as well, without additional CPU load.

Spire 1.1 beta has surprisingly low CPU consumption.

Never really ran into trouble so far anyway though, as my desktop computer has decent processing power.

Damn! forgot some!

Waldorf Attack < 3% (this is amazing considering it a pure drums synth!)
Waldorf PPG v2.2 < 3%

Can you please inform us what cpu usage (average) of Spire and what is your CPU?

Why amazing? 3% sounds like a lot for a drum synth

Helix uses no cpu at all and sounds wonderful.

That's great, so one can run it without a computer as well?

But you need a magnifying glass for it.

Well, compared with Tremor for example. I remember it could reach 20% easily with my laptop when I tried the demo a year ago.

Which drum synth you are comparing to?

How do you measure these things? I have no idea.

None. I was just wondering because unlike with a synth pad one does not play 3 or 4 notes continuously for seconds. A drum synth plays more like a string of short peaks

Tunefish is as low CPU as it gets but still a wonderful niche synth.http://www.tunefish-synth.com 10 kb compressed machine code.

Tunefish - Free VST synth - vstplanet.com:

A synth like diversion it completely depends on the patch, number of keys pressed, quality level (x2 x4 x8) or whatever it's called, the list goes on...

I suggested that some time ago, but people here said it would not be possible to come up with a reliable ranking...

I can't see why not. Using a standard benchmark for single core CPU, then applying it with a baseline VST host like VSTHost and measuring it with a default single voice patch to be reproducible in any synth. It would be a bit time consuming but can give reliable results from trusted sources.

For example, Corona is getting 2.2% CPU for a single note (sawtooth waves, filter open, fast adsr, no modulations) with 3 oscillators on a i7 mobile at 3,4 Ghz using AU Lab 32-bit application. Geekbench gives 3507 points to a single core, so with some equations we could get how much would it be like in other CPUs.

Favourite Synths that uses 10% or less of your cpu
