ehhh. it depends on alot of things, not just EQ.
and all of that depends on the synth you use.
i cant sleep so i fiddled on my virus b and came up with this:
[[ LINK REMOVED ]]
second attempt. my first attempt recorded really blurry and quiet and i didnt understand why - just found out one of the input cables on my virus wasnt plugged in all the way. reuploading now :\ it does have post processing on it however: namely, fruity chorus (although any chorus with a high EQ will do it), fruity delay 2 (set to ping pong delay) and the whole thing is compressed using voxengo crunchessor.
ill post the unprocessed sound later so you can see how much of an effect post processing has - it really changes the treble and mids since the virus oscillators are not very bright. with a little bit more work i think i can get it closer. the filter isnt quite right. i know its wrong actually because im using the 6 pole filter and both filters. i dont think the JP even has a 6 pole filter. i just used it because it sounds nice.
edit: i forgot to mention. theres also an EQ on it. bright. ill bet my last euro that the supersaw oscillator has high shelf EQ on it because it is so bright. actually, thats what i did with my virus patch right at the end of the effects chain. stuck a high shelf around 10 khz and a low shelf around 200 hz. that took the emphasis away from the mid ranges. now that i listen to it, theres a bit too much boom on the low end so i probably have to soften that low shelf a bit.
another thing: for virus users - the pure saw wave oscillator doesnt sound anything like the saw wave or the supersaw oscillators on the JP. especially below C4 on a piano roll. the virus pure saw wave gets really 'buzzy' below C4 for some reason. i also had this problem when emulating a 303 on my virus b (which can be done by the way and i can prove it). but you can compensate for the differences in oscillator properties by mixing between waveforms and EQing the end result.
i had to mix waveforms to get a JP'esque saw wave sound. first oscillator is a mix of saw and square (nearly all square) with a bit of PWM. osc2 is mostly saw with a tiny bit of square and the third oscillator is slaved. they are all mixed in equally. then both oscillator pulse widths are modulated in opposite directions using LFO1 and LFO2.
when you add the slaved oscillator there will be a kind of audible 'hissss' accompanying the sound. thats normal and kind of like the JP supersaw too. in fact, on the virus theres not enough hiss in my opinion. so i added some extra white noise in the oscillator sub menu. rack it up to 127 so you can hear it really clearly, then increase the noise colour so that it sort of 'harmonises' with the note you are playing. then turn it down to about 25 so its barely, barely audible. obviously, analogue boost and punch intensity is maxed. for making most VA or analogue sounds it usually is.
after that its the usual routine: use LFO 3 to modulate tuning of osc1 & 2, detune up until you start to hear a strong 5th (between 45 and 55). then unison x3 and high unison detune. the rest is random detail in the mod matrix to make it sound more alive - i set the first assign source as random with its destination as osc3detune. every time you press a key, it randomly detunes the 3rd oscillator slightly giving it a bit of subtle random movement and makes it a little more analoguey.
if you dont have a virus then i guess you could use any synth that allows you to mix sines, saws and squares with PWM. albino springs to mind straight away although i hate its filter... oh well...
things i need to correct but know about at this stage:
1) saw wave oscillator behaviour below C4. below C4 the virus saw gets really buzzy and bitty and its a dead giveaway.
2) attack transient. i have recursivelely modulated both filter and amp attack in the mod matrix because the JP attack envelopes are non linear. at least from the sound sample i had. i cant tell what it is though so i fluked it and tried to get as close as i could. need to redo this slightly.
3) PWM goes nuts at around 18 seconds and also periodically throughout. ill fix that since its probably not oscillating correctly.
---------------------
with a virus TI you could probably get really really close - almost indistinguishable because the hypersaw oscillator is brighter than the regular virus saw oscillator. and it has the 3 band EQ from the Vc.
