Thanks for updating the thread title.

Gave this a quick demo today. It sounds quite good indeed. If I may ask the question that all Juno emulation makers get asked: any chance of a standalone Juno Chorus FX? That may be a good permanent freebie after this goes commercial.

Support the beta with €5 or more and you'll receive a free license for the final paid release of EightySix when it ships — no upgrade fee.

Bought.

I'm looking forward to having the Voice and Drift faders working. Those will be nice added features to make it better than the real thing. Would you be willing to add polyphonic unison?

There is one.

Agreed! This actually already exists, I just need to update the DSP with the fixes we came up with in this thread (the phase cancellation issue) and put it out there. Probably during the coming week. Cheers!

Just a quick word on the popular alternatives: they are all great sounding chorus plugins, but they're not accurate to the JUNO's chorus topology. They mostly use simple symmetric linear delay lines with no BBD modeling. Eightysix actually models channel asymmetry, the BBD chain, level-dependent BW, BBD clock-rate tracking, etc. What I haven't modeled yet is the Chorus I+II double mode, but that's on the list. The standalone plugin will basically give you control over the the chorus parameters, but so far will not let you do the I+II (which tbh sounds horrible on the real hardware) — I never gave it a lot of thought, but it might have some sound design value to some, so yeah — it is on the list.

Before I forget: what I also haven't modeled yet is the hiss. The BBD chips are notoriously noisy — turning on the chorus on a real JUNO is basically like walking down along the shore. If someone wants this, it can be done, just let me know

If you add the hiss, please have an option to turn it off.

Yeah, hiss is an accuracy I'm happy to live without.

I'm curious about the tuning sliders. What will those eventually be doing? The voice slider reports as OSC2_detune in the DAW.

Soo...we need an emulation of a chorus (of which there are sooooooooooooooo ooooo o o o o many), BBD chain and clockrating etc...but no hiss.....got it 🫩

[Funkybot's Evil Twin]

If the noise is a natural byproduct of the circuit and BBD then I would say add it with a level control. A little bit of noise can be very pleasant and warm with the Juno's. But if you're just going to add white/pink noise into the signal chain, then no point.

And yes, I'm also aware of all the other emulations of the chorus, but as the developer here points out, I think they all leave a little something to be desired. Except maybe the Softube, but there isn't a standalone version of that without loading something else.

I think people record their real Junos and Jx's with the chorus off, and use plugin emulation choruses to avoid the noise.

...then run them through VHS plugins to introduce noise, no doubt!

[Morphoice]

No worries — the noise will be switchable if added at all. We could also do an "age" knob that makes the BBD issues less pronounced and kills the hiss. I've replaced the chips in JUNOs with newer ones many times to soothe the problem. It's usually fine on album recordings, although if you try to sample chorused sounds in Kontakt for later use (the JUNO-6 has no patch memory) it stacks up pretty badly. Those we did indeed with the chorus off, but never found a similar-sounding chorus plugin to replace it with.

As for the rest of the parameters in the lower row, I want to add a few useful things the real JUNO doesn't have, like initial bending, velocity control over VCA and VCF, and yes, maybe unison with a detune function. But it will take some time to get finished. There could also be polyphonic aftertouch in the end. We have it in Unstable, so it should be fairly easy to port, although it was a pain to get working. There are a couple of bugs in the framework we had to work around.

I always thought it would be cool if someone said, "I started with an exacting Juno emulation, but added a second oscillator with fine tuning and an Osc1/Osc2 blend, a second full ADSR envelope, and an extra LFO with more destinations". Create sort of a Super Juno. Something that's a Juno at the core with features more closely akin to a Jupiter-8 except maybe without the sync and crossmod.

But I digress.

That would be Image-Line's Kepler Exo. It's everything you said plus sync and crossmod, 4 LP filters, filter FM, adjustable sub osc phase, and some effects. Unfortunately it's only available within FL Studio.
