Re: Was the Roland D50 the first VA Modelling Synth?

So it is decided by if you have a generic DSP or not ? Since the D50s processor wasn't sold to other campanies (nevermind that it does the exact same thing as a Freescale 56k) it's not a VA ? Never heard that definition before. Actually, it doesn't (56k). You incline that most of D-50 signal proces...

Re: Was the Roland D50 the first VA Modelling Synth?

So how does a D50 work exactly ? What algorithms does it use ? It doesn't matter what algorithms it uses, if it uses any algorithms it's different to analogue circuitry. Well yeah,that is obvious but what bearing does that have on this discussion ? It is easier to tell what's going on under the hoo...

Re: Was the Roland D50 the first VA Modelling Synth?

His statement that other synths had throwback architecture is true, and demonstrated amply by at least two huge synths which came out around that time which were also digital: the Korg M1 (you might recognize that name, being as that it was among the top sellers of all time, and was in no way emula...

Because analog circuit design is quite different from digital circuit design.

Re: Was the Roland D50 the first VA Modelling Synth?

It isn't surprising that the majority of digital synths at that time had similar features to analog synths. You don't just change everything when a new technology comes around. You adapt it to what is already there. You mean like the Yamaha DX7 ? Or the Fairlight or Synclavier ? Were there any othe...

Re: Was the Roland D50 the first VA Modelling Synth?

The comparison with a CZ is valid in that both synths have a UI that is an LPF. Casio calls it a DCW, Roland calls it a TVF. BUT under the hood it is most certainly not an LPF (or a DCW). It's a TVF. Unless we can get someone from the D-50 team to explain it, we have no idea what a TVF is. There ar...

Re: Was the Roland D50 the first VA Modelling Synth?

A "Virtual" instrument, as knolan pointed out, means created by mathematical model, or, if you like, a program running inside a dedicated processor (be it DSP or MCU controlling PGA). To start with,that is two completely different and unrelated things. And as has been pointed out by several (includ...

Re: Was the Roland D50 the first VA Modelling Synth?

Because no one was interested in modeling analog waveforms for the purposes of marketing analog-sounding synths in 1987, that's why. And yet they did. When? You mean the paper you cited in a previous post? That was presented in 1996, wasn't it? No i was talking about the D50. It had oscillators wit...

Also, look up the ads for the D-50... that would put this whole silly concept to bed immediately. I tried but couldn't find any. Here in Sweden it w...

Re: Was the Roland D50 the first VA Modelling Synth?

"Analog modeling" was a term to indicate that there was some sort of actual mathematical imitation of analog sound happening on an electronic level. Again, does not remotely apply to the D-50. Why not ? If you look at the classic papers "Alias-Free Digital Synthesis of Classic Analog Waveforms" and...

Re: Was the Roland D50 the first VA Modelling Synth?

...It all comes down to how strict you are with the terms. With genuine respect for the points you make and to the other informative posts, I don't agree. There is absolutely no ambiguity here. The word 'Virtual' in Virtual Analogue literally means that the analogue circuitry is actually modelled i...

ZeeOne wrote: The poster(s) on that other board giving the D50 credit as being the first VA are kind of thinking of it that way because it was easier to program than its rival the Yamaha DX7
Or maybe they think that way because it has a fully featured subtractive "analog style" synth engine under the hood?
