Ummm, can you give at least one, preferably 'a lot' of examples of this please?

Perhaps it's using the nomenclature VCO and VCF - like on the AN1x.

The Virus A/B/C had "Advanced Simulated Analog Synthesizer", the Nord had "Virtual Analog". The JP used "OSC" and "FILTER" on the labels; so did the Novation Nova. The MS2000 used "OSCILLATOR" and says "ANALOG MODELING" on the front.

Have I missed some VAs? :)

Are you saying that's evidence of saying they're analogue?

I don't see anything misleading there.... SIMULATED analog, VIRTUAL analog, analog MODELING

plus whether they are digital or analog, they are still oscs and filters
No one cares, no one sympathizes,
so you just stay home and play synthesizers.

hey there people!
I bought my sirius some months ago now and i kept hearing a buzz when i ran it trhough my quad capture and directly to my beats too, i'm going nuts here... i know it can sound amazing but the quality isnt getting there... just buzz and distortion...(bad type) so i was wondering if any of you could help me... cause i love the multi synth options and i think it can sound amazing but its just not doing it so far...
thanks in advance

Either a gain mismatch or a ground loop...
You might also try the JayB's sysx for the Sirius:
JayB wrote:The package includes another MIDI-file containing one SysEx event to modify the Sirius's system settings inluding both FX parts and the overblast parameters. The overblast is nothing but a 2-band shelving EQ and this command will set them to a more HiFi position. Put this to the start of every production arrangement because these settings aren't saved when you turn off the unit. Also don't touch the overblast knob after you sent the SysEx command, otherwise the overblast settings will be reset to default values.

I don't like the drums, but the drums like me!

Got one too finally a few months ago.

The reason I know now it is so "beefy" is simply because of the detune feature/knob between the two elemental tones. On my rompler of choice (RS7000) I can't control amount of a detuned voice, the elements/waveforms are pre-detuned and amount is controlled together, so I have to emulate that using a second track/voice and fine detuning it against the other voice. I'm basically wasting a track to do it, but doable, it is extremely awesome to have a control specific for simply fine detuning between the twoe elements on one voice. I'll also agree that it is kind of limited in voice editing compared to most VAs, but most of the necessities and some kick ass stuff is still there.

As for buzzing and humming, the power jack plug is shittily mounted, I believe if I remember right after redoing mine after previous owner hard wired it, has a specific wire going to the case from it that grounds it, I was even getting a slight shock off the case before I figured that out. Check inside I guess to make sure yours didn't get pulled off, could be causing it.

This whole question should probably be surgically removed and planted in the 'help' section; that being said - having owned one many years ago, I recall having a similar problem and it being tied to the power supply not supplying correct voltages (in my case it was extremely low voltages); if you have a multimeter and the wherewithal to understand what you're looking for, I would start there. You should see very close to 10.5 volts, DC at the connection that attaches to the Sirius.

Otherwise, you could begin with a factory reset, which I'm not confident will solve the problem. It could be more than a single problem causing this. Power off, press and hold the write button, power on. It will ask if you would like to initialise, select yes. Be fully aware this will initialise the synth to factory defaults. If you have patches stored that you've not dumped, fair warning.

If neither one of those easier things solve the problem, you'll want to source a repair center to have it looked at.

Also go here for a manual if you don't have one (and potential support, but I've no idea if anyone is still listening out there): Quasimidi Support Site
