Can u give us longer samples with min detune and full detune? Is min detune 0 or not?

asymetrical detune - exactly what i did with my osc, tho i used an algo for the asymetrical values..

thanks for the samples!

But how much is 1Detune when fully detuned?

I do not know, that were the only supersaw samples I have, and if there is someone with the real jp, then we can ask him to sample it with the required settings. From the posted samples it seems that the max detune is around +-80 cents.

I have long raw audio samples of a real JP. (Each sample has the "C" notes of the keyboard - so there is 5 notes in each sample. )

The list below refers to the position of the knob on the JP, as different levels of detuning are applied.

1. None
2. Quarter
3. Half
4. Three Quarters
5. Full

I will not be uploading these samples for mass downloading. I will however provide them to anyone wanting to analyze them (shoot me off a PM). Its in a RAR file, and 10Meg in size.

Seems like the tuning of the detuned saws is not even exponential.

Full detune:

1st pair: f*(1 +/- 0.02)
2nd pair: f*(1 +/- 0.06)
3rd pair: f*(1 +/- 0.11)

That also rules out the chorus thing.

If you guys are really having trouble finding JP-8000/8080 samples of the real Supersaw, I could get you some later tonight. I'll be at work for the next 10 hours or so, though, so I can't help but believe you will probably have what you need by that point.

Nonetheless, this conversation is rather interesting, and I would love to help out.

If it was a chorus you'd see the extra harmonics circling the main one, not statically detuned either side.

not if you use 2 triangle LFOs with opposite phase!

I have a JP-8000 sitting right here. Unfortunately my recording interface doesn't work with Windows7, so I'll need to install and boot to XP, I won't be able to do this until tomorrow. If you need any samples/recordings for any of my hardware I'm willing to help out where I can. PM me with specifications and I'll see what I can do. (if you don't PM me I might not get the message

)

Or maybe a radioactive one?

Ah yeah, I didnt think of that.

What kind of samples would make it easiest for you guys to do what you need? 24/96?
24/44.1?

Do you need multiple pitches, or just a middle C at varied settings of Supersaw?

Oh, and how long should each sample be? Is 1/4-1/2 second of each setting enough, or is there slow phase drift that will require longer samples?

Here you go. 24/44.1 glory. There are about as many supersaw samples in here as you could ask for. All middle C, roughly 3/4-second long. Basically, I just moved the mix fader up between each note until it reach the top, and then increased the detune fader a bit and did it again.

Naturally, the very first note has the controls at 0%/0%, and the last note has them at 100%/100%.

Hope these help.

(Oh, and these come from an initialized patch, so no filter/OSC 2/chorus or any other junk.)

Roland Supersaw - any idea how the original was done?
