Aurora FM - New Win(32/64) VSTi FM synthesizer - Introductory pricing

[mladi]

You do need a new license FILE per install, but those are free and never-ending. I will give you licenses to run on a couple of different computers simultaneously. At the very least I will keep sending you license files for the rest of our lives, but it's much more likely that I'll remove the licensing completely at some point much sooner than that.

In short, if you pay for this synth, it's yours and you have nothing to worry about. I'm only stopping theft, NOT hindering paying customers in any way.

Yet more new goodies!

I was synthesizing sound effects and getting annoyed by the limitations of the fixed 0° start phase for the LFO's, so I decided to ameliorate the situation. That forced a shuffling of the mod source controls, which in turn opened up room to add something to the S&H, and that aligned perfectly with my idea to add some input source combinations to the S&H. (Improved modulation... Excellent! )

• New: Selectable start phase for LFO1/2 -- each of the 4 quadrants (0°, 90°, 180°, 270°)
• New: Additional source inputs for the S&H -- LFO1+2, LFO1+Env, LFO1+Rand, LFO2+Env, LFO2+Rand, Env+Rand
• Changed: Changed the operator sync phase control to make it consistent with the iconography for the new LFO start phase control, and the waveform selector to make it more consistent with those.

Enjoy!

Reading about this synth make me want to have will test the demo today after work if all goes well that's another sale always had a soft spot for the sound of FM synths.

Wonderful synth, payment sent.
Silly low price there, thank you is much appreciated.

New version!

• Improved: Patch randomization got a whole lot better! There's now a 2-axis control for performing a randomize operation, and where you click on the control determines:
  • x-axis: the number of parameters that are randomized
  • y-axis: the depth of the randomization, usually the range of deviation from the current parameter value, but also with lower depths favouring probabilities of more musically useful values and higher depths increasing the probability of crazier values.
  Left-click on the control to randomize, or Right-click to perform a reset + randomize -- super handy for quick randomization!
• Improved: Also improved the performance of GUI updates after randomizing or changing patches
• Changed: Swapped the locations of operators 5 and 6 for algorithms 14 and 15
• Fixed: Some issues with parameter locking

To further elaborate beyond just the update headlines, the actual scoop is that the randomization is seriously improved and a hell of a lot more fun and satisfying. I'm constraining the values a lot more meticulously than before and have really tried to make sure that the randomizer produces pleasing results more often than not. I think it's a huge improvement in quality, as well as giving you more control with the 2-axis button design.

I hope you all dig it!

It seems that the second waveform (dx11) is not really accurate , it does look like the waveforms depicted in the dx11 manual but it's not the actual waveform

They appear to look different, but they sound the same, they are made from the same harmonics just in different phasing.
And yeah the manuals aren't accurate that's for sure.

The waveform is a cubed sine , there is a thread at the reaktor forum and it seems that the wafeforms depicted in the yamaha manual are not really correct .
I guess it ‘s these waveforms that are used as reference by the aurora developer Ryfi
I don’t agree they sound the same , the Cubed Sine has a much softer tone compared to aurora’s ( see screenshot )
A square and triangle have the same harmonics but they don’t sound the same because of diff phases ( for the triangle that is )
Sure , in the yamaha these waves are made from 1/4 of sine in a look up table ...

[RyFi]

Holy shit, you're right! And I'm an idiot! At some point I got it in my head that that waveform was a translated sine, and that made perfect sense given the sine in ROM of the Yamaha FM's, so I ran with it and never questioned it. "Pfft, I know how to get that shape shown in the manual from a sine wave", thought I. But lo, I was operating on totally bogus information that I never questioned since it perfectly fit in with my understanding of things.

And to add even more absurdity, I had contemplated adding a sine^2 (bipolarized, of course) and sine^3 waveform to Aurora FM since they have nice spectra but decided against it since I was already adding 7 new ones and surely that was going to be plenty useful enough, I figured. Guh!

Welp, needless to say, I'll be adding the correct waveforms in an update, but keeping my incorrect ones in there too so I don't break patch compatibility for you fine folks. But this isn't going to happen for a while yet, because I have some BIG NEW features that I'm still working on .

Thanks for bringing this to my attention!

[RyFi]

The waveform is a cubed sine

Plot twist: Nope! I've determined that it's a bipolar sine^2 (ie. the values of sine^2 but with the sign of sine, (without the absolute value'ing / rectification that comes with multiplying a negative by a negative and getting a positive)) (is there a proper mathematical term for this? I'm not mathy enough to know).

In Sine^3 the first two harmonics are high and the rest are totally reduced, unlike sine^2 with its steadily decreasing harmonics' amplitudes.

How was I able to determine this for myself? Why, with my dusty old noisy-outputted TX81Z, of course. Yes, I just incriminated myself -- I own a TX81Z and never bothered to test if my waveforms were correct. Like I already acknowledged, I'm an idiot!

[gentleclockdivider]

All good , anyway I build a clone in reakor using the cubed for waveform 2 sine and it sounds pretty close .
here's the reaktor thread

Hi. Does that mean I can load a Dexed patch-file too into aurora?

Dexed features supposedly do not surpass the DX7, and it exports DX7-compatible sysex banks, so they also import into Aurora, but the tone is a bit different. Dexed patches seem to sound better in Dexed, from my few test patches. Not sure why that would be; ‘twas just a quick test.

Hey Ryan, I have a couple of questions. Would it be possible to add a button that collapses the effects section in order to make the GUI less busy? I doubt I will use the effects very often, as I'm inclined to process the synth first through DAC emulations and then through external FX. Also, I am interested whether you're planning on adding the ability to read external custom tuning files such scl apart from the built-in alternative tunings.

I haven't bought the synth yet, but I'm bound to pull the trigger sooner or later, as it's too cheap, sounds too good and I'm too much of an FM addict to not buy it. I likewise dig the old-school look of it. Anyway, the best of luck with your project. The more FM synths, the merrier.
