Prophet-emulation attempt

Hello! I´ve just started to make a Prophet-emulation (not really an exact emulation but something close to it). What I need to know is:

The Freq-knobs in the Oscillators (what do they do exactly).

I know that the poly-mod uses the filter-env and the second Oscillator for additional modulation-tricks, which I will try to implement, but what do you feel important to do in addition?

I am planning to include an 8-Step-gate instead of the Bank/preset-switches in the original (which are 8). What do you think of that?

Also, should I "skew" the Square-waveform in the way the Moog-synths do it (I know how to do it (using a triangle-oscillator)), or should I stay with the stock square-waveform?

All suggestions are welcome (and I might implement the ones I understand and can make).

I salute you all!

(I will present the full OSM and plugin here on this forum when I´m finished with it, so that you can test it and evaluate it yourself).

Great project! 😮

If you want to make some real analog fatness, then I'd be happy to contribute. 😈 😍

Interesting project but why make something that has been made so many times before ? 😈

What about its little sister?

Lol. Well. I was thinking maybe a smaller project to start with 😉 The Pro One has parts that all look like they could be made fairly simple in SM and then we can concentrate efforts on making it sound really really good instead. The Big Evil Sister looks a lot harder just to get the parts right 😈 But this is Nekros project. Just throwing in a spontanious thought 🙂

I know there are some free prophet-emulations and some (close to) perfect ones, but where is the harm in attempting to make something similar? I just love the Prophet-synth, and thats why I want to try to make something close to it (the word "emulation" might not be appropriate here), and try to keep most of its original features as close as possible.

However, I will include some new or different approaches and/or features to the main architechture of it. I will call it "Baphomet Vsti" and you will find it here on this forum soon...

BTW, I find the Freq-knob to be kind of bewildering. AFAIK it´s a coarse-knob and therefore has to be (?) some kind of "semi-knob". But, AFAIC in the "PRO-53"-manual (try to find a Pro-V manual online anywhere) this knob reaches over 4 octaves!?

What? This is quite confusing somewhat. The knob in question has 0-10 range. How will it then display a range of 4-octaves as the manual says?

Well, perhaps I´m just stupid, but I really would like to know...

One solution I´ve thought about is to make the range of the Freq-knobs for the Oscillators to be (0-10) or to make the range being from 0-12.

I dont know, but it seems more logical to me...

Are you sure about that? I don't know anything about the synth but i guess 4 octaves are covered by the frequency and the octave knob together. So this would make sense: Octave knob 1-3: 3 octaves + Freq knob 0-10: 1 octave. The display of 0-10 seems to be caused by a unique knob display design on the whole device. So i'd take it as a shortcut of %.
