Intellijel Quadrax

Post by Neo » Fri Mar 29, 2019 4:15 pm

Quadrax... nice. What we know so far:

Image

4 channel AD, ASR, LFO envelope generator

4 x CV inputs! Obv 1 per channel, funtastic! No need to DIY a 2hp Quadra expander

CV's can be mapped to:
1 - rise and fall?
2 - ?
3 - rise
4 - fall
(I was wrong about this... see Update below)

4 modes:
1 - rise/fall
2 - rise/sustain/fall
3 - cycle
4 - ? (Update: it's an awesome bipolar morphable LFO :sb: )

linear/exp knobettes

14 hp

Unknowns:

Do the rise/fall knobs work as attenuators for CV inputs when CV inputs are mapped to rise/fall?

Does it remember switch states through power cycles?

What is the 2nd CV destination?

What is the 4th mode?

How much will it cost?

When can I get one?

(disclaimer... I have no inside info and any of this could be wrong)

Updates:
kisielk wrote:A few details: the 4th mode is a bipolar LFO. The rise knob becomes rate, the the middle shape knob selects between several LFO shapes, and the fall knob is a morph that is unique to each shape.

The 4 CVs are actually freely assignable to any combination of parameters (rise, fall, shape, and level) for any of the 4 envelopes. The assignment is done via entering a “mod matrix” mode with the buttons.

The left column is not not CV assignments but sync modes. Every envelope can sync to the previous one either on trigger, end of rise, or end of cycle.

The offsets do not change into attenuators :)

The module is still a proto so some of these details may change as we move into beta testing (and front panel will definitely change). Should be released in a few months from now.

If channel above to the LFO channel is set to something other than LFO and you create a trigger dependency then the previous channel can be used to reset the LFO.

State of the Quadrax will be saved on power cycle.

Jumping the gun here I'd say.

Although I'm sure you're on the right track, we'll find out all the info in the coming days. Hopefully sooner than later ;)

I sure hope not! This is a huge mistake in terms of design if you ask me. Because then you need to ADD an offset to the incoming signal. It's easy to find an attenuator - they're very common modules. It's harder to find an offset. It's even harder yet to find a module that will AMPLIFY. Modules signals should be hot from the start and knobs should never change from offsets into attenuators. Biiiig pet peave of mine.

A few details: the 4th mode is a bipolar LFO. The rise knob becomes rate, the the middle shape knob selects between several LFO shapes, and the fall knob is a morph that is unique to each shape.

The 4 CVs are actually freely assignable to any combination of parameters (rise, fall, shape, and level) for any of the 4 envelopes. The assignment is done via entering a “mod matrix” mode with the buttons.

The left column is not not CV assignments but sync modes. Every envelope can sync to the previous one either on trigger, end of rise, or end of cycle.

Thanks kisielk, looking forward to hearing more.

Too funny, I was wondering early this morning if and when a 'Quadra 2' would arrive.

I love my quadra, and this looks like a smart evolution of it.

I'm pretty sure I would miss EOC outputs from the expander though. I guess I'll need both :)

That is the beautiful thing about linking channels--you can set the second to act as an EOC output.

Thanks kisielk, very exciting news. I've included your update in the original post for clarity. Looking forward to this beastie.
My one remaining unknown (other than price) is the power cycle save state. That would be a big plus for me.

Also of note is that in LFO mode the TRIG jack has detection so if you have a clock source then the LFO rate becomes a division of the tempo and the rate control becomes a +/- CLK div. i.e. bpm synced LFOs.

If channel above to the LFO channel is set to something other than LFO and you create a trigger dependency then the previous channel can be used to reset the LFO.

This is quickly becoming a powerhouse module!

I'm very excited for the compact feature rich configuration.

Will env shapes/snappiness be similar to the quadra? Already have 2 as they are by far my favorite envelopes. Could see dumping my contour for one of these

Looks like a great update! Four flexible envelopes with separate controls in such a small space, lovely.
New track! Drum synthesis heavy, melodic piece where Instruō harmonàig is doing the chords. 🐡

Very nice, love my Quadra+Expander but this looks like a thoughtful improvement on the quad AD concept.

Don't know if I missed this, but will it have both AD and AR modes? I had been considering getting a quadra that had been up on my local market, but now I want this!!!! :yay:

My Quadra is an absolute workhorse in my system, use it in every patch. This looks like a fantastic evolution. Hype! :banana:

Yes exactly. You can set the linked channel to have zero attack and it will so basically this. There was a lot of debate during the design stage about this but we decided that the internal cross-patching and linking covers a lot of the use cases and it was more important to keep the module size down.

I will also say that personally I’ve had a ton of fun with this module, Quadra has always been one of my favorites and this one retains the same spirit and immediacy while providing even more possibilities.

That makes sense, as does the Cv matrix. I almost never have CV going into every possible input on my Quadra expander, end even there, the normalized connection between the attack and decay CV gets utilized a lot.

I plan to keep my Quadra and expander. But this will be replacing my Stages. Haven’t really locked into using that as much as I wanted to. This seems much more immediate. Can’t wait.

Shame it doesn't have EOR and EOC trig generators.

The linking sounds cool, but I find the end of stage triggers to be invaluable when creating more complicated events.

Even more reason to add this to what you've already got ;)

module looks really nicely thought out. i think the idea behind using the linking for the eoc output is a clever way to keep the hp down while maintaining other important features. I take it the entire thing is digital now, as opposed to Quadra. Really hope it maintains the same feel for envelope timing and sound, like others here Quadra has been my favorite envelopes thus far

any way this behavior can be optional? i tend to prefer the reset type of syncing for finding odd timings within, although synced is definitely useful as well as an option.

omg I was about to pull a trigger on a Quad VCA + a Quadra. Would you guys be able to give any release info/dates by now? I'll definitely get the Quadrax. :party:
