Jupiter 8 - cross modulation effect

I'm wondering how u guys are using the cross modulation effect.
Since there is a pitch change I find it a bit unusable for playing.
Any tips? tricks? advices?

If your JP8 is unusable for playing.. Sell it to me! Ill find a use for it ;)

I found it pretty useless on my Jupiter 6. Good for some synth effects and such with osc sync, but I would have much rather had filter FM personally.

It's mostly usable when OSC2 is used as an LFO.

if used slightly to bring warble n animation to vco1, i re-tune the instrument to accomodate new pitch. made a few awesome metallic pads i use this way.

also its great when used in low freq mode as second lfo, esp if u use PWM waveform and set the PWM source to very slow LFO. or i use it full-out via env, for clangorous, organic? metal fx. here's an example of these two apps, with random apreggio. besides crossmod i'm tweaking reso, filter, env and vco sync as well:

If I remember correctly I used some heavy cross mod on this vid.
Synths are not supposed to play only "melodies" or "chords" or "tempered" music. Open your minds and ears!!!!

time for my first ever post....

I don't know what it's like on the JP8, but I use cross mod extensively on my Jupiter 6. If you use it just slightly it's great for adding a bit of almost de-tuned dirt to sounds, especially basses. I don't know if you can do this on the JP8, but syncing the oscillators as well as using cross mod greats some really fat dirty sounds especially if you set VCO1 1 or 2 octaves higher than VCO2. Nice for some dirty bass again, set VCO 2 to triangle or square and set the mix more towards VCO2.

You can also just create some whacko nearly in tune/out of tune leads with cross mod. Check out my track 'Deepdive'

5min 40s - the 'whoop whoop' pitch env sound doing the lead melody is the JP6 with a cross-mod patch....

When using cross mod and sync together, it's possible to get the pitch tracking to invert itself on a Jupiter-8. Sick s**t. I got all kinds of verklempt kitty noises that way.

I just got my JP-6 back from the shop after about (yikes) a year and a half -- and just did what Stafftunes suggested re. basses and cross-mod. He's absolutely right -- in fact, I think it's what people mean when they say that while the straight up Jupiter 6 bass isn't super fat, you can make it pretty heavy by strategically adding in harmonic grit like cross mod. Nice suggestion.

Ditto on the cross mod + sync idea.

If using cross mod by itself, I like using very small amounts just to add subtle complexity to the patch.

I use cross mod on the MPC5000 VA all the time.

This video has an example of the cross mod doing the typical bell thing. It's about 9 minutes in on the video.


This video has an example at the beginning where I'm doing more of a osc sync thing with it. The audio is a bit overdriven on this one though.

Cross mod is just Exponential FM as opposed to linear FM (DX7). Play with it more especially in conjunction with sync. Try different waveforms on the two oscillators. Try removing key tracking from the modulating oscillator, (Prophet 5 poly mode style). Play with it, it has a lots of sonic possibilities.

My Jupiter 8 cross mod and pwm are reversed. When I moved the pwm slider I get the cross mod effect and vice versa. Strange. I've had it a couple years and had no issues. I don't if a previous owner was messing around with the guts and mixed them up. It doesn't bother me, I just thought it was a weird issue to have.
