1 year ago I really love this feature request. I think you are right, it would suit Juniper quite nicely - providing I can find a way to make it fit nicely with the workflow, that will be the main challenge here, especially if multiple outputs are required as you suggested.
I'll need to do some more reading into this topic to get a greater understanding of what is required, thanks for the links they are helpful.
Or would it be possible to use Gin's additional inputs as outputs
Unfortunately Gins inputs cannot be used as outputs

Feature request & motivation
Would be amazing to have chaos-based modulation as a wave option besides traditional waveforms and random, like a Lorenz or Chua strange attractor (or other - see Vult Caudal's different approach). Chaotic modulation can be more interesting than pure random as there is some kind of pattern going on, within finite boundaries, which makes it a mix of random and deterministic. Love those drunk/super slow modulation sources for drones and I think such thing would feel right at home within the Juniper, extending its palette quite a bit into less ventured territories, making it even more versatile.

Modules implementing such chaos-based modulation
Triple Sloth — Nonlinearcircuits : This module contains 3 Sloth chaos circuits. Each one runs at a different rate; Torpor takes approx. 15-30 seconds to travel around 2 strange attractors, Apathy takes 60-90 seconds and Inertia takes 30-40 minutes.
Ornament & Crime Low-Rents : Low-rents is a port of the Lorenz attractor modulation generator from the easter egg in the Mutable Instruments Streams module, to which Rössler attractors have been added. Two independent function generators are provided (referred to here as Generator 1 and Generator 2), with each generator calculating both the Lorenz and Rössler functions simultaneously, using the same phase accumulator, but with the rate/speed of each generator independently settable. Both the Lorenz and the Rössler functions output three values (x, y & z), and various combinations of these can be mapped to the four output channels. The chaotic strange attractors work best as slow modulation functions.
Orbit 3 – Joranalogue Audio Design : In everyday usage, 'chaos' means 'disorder, randomness'. In mathematics however, chaos has a very specific meaning. Chaos theory deals with systems exhibiting highly irregular behaviour, seemingly random yet completely deterministic. Applying this to the world of modular synths opens up a whole new world of modulation opportunities, introducing a natural irregularity to otherwise purely ‘mechanical’ music, yet with much more control and repeatability than just simple randomness. In chaos theory, the combination of all possible oscillations at a specific set of parameters is known as the ‘attractor’. Orbit 3 incorporates a modified electronic analogue of the classic double-scroll attractor. Since it contains some (bi)stable regions in addition to chaotic ones, this type is known as a ‘strange’ attractor. https://youtu.be/GuCcnCAm3cE
Zlob Modular: Diode Chaos : Diode Chaos is a 3hp analog chaotic low frequency voltage generator. It is a unique module because it has never existed as an electronic music instrument until now. The module is based on a circuit from a paper called “A simple chaotic circuit with a light-emitting diode” written by Volos, Wang, Jafari, and Kapitaniak. Diode Chaos produces 3 phases of interrelated morphing voltages including a chaotic trigger out. The range is 20-30 seconds a cycle up to audio rate, although only the X out and TRIG out go up to audio rate. The frequency is controlled by the RATE knob. Each output exhibits different behavior at different rate settings. X,Y, and Z outs like to stay in the 4vpp range although at different RATE settings the outs can reach 10vpp. The TRIG out chaotically releases 0-10v triggers although sometimes it will spit out smaller voltage peaks.
Mutable Instruments Streams easter egg : The module turns into a generator of chaotic signals (Lorenz system).
Mutable Instruments Stages Qiemem Alt. Firmware : Double-scroll attractor, a smooth chaotic system similar to the Lorenz system (single, looping, non-gated)
Expert Sleepers Disting MK4 and Disting EX M-8 Chaos algorithm : This algorithm generates chaotic CVs and/or gates according to the Lorenz equations. The X & Y inputs set parameters of the equations – X affects 'r' (aka 'ρ'), and Y affects 'b' (aka 'β'). With the CVs at 0V, the parameters are the classic values as studied by Lorenz (28 and 8/3 respectively). The A & B outputs generate the x, y or z values of the Lorenz system, or gates based on these values.
Vult Caudal : Just discovered it. It's a very interesting module to add to the list as a reference, as its chaos signals do not come from the strange attractor paradigm but a more mechanical approach (based on the model of a multi segment pendulum, with other models available in the latest design). Still early stages, Leonardo told me that more documentation was coming.
Neutron Sound Dust of Time : A special addition to the list as this module is many things in one, starting with 2 stereo oscillators, but also comes with serious modulation power onboard, with LFOs and chaos modulation (and 2 CV outputs). What is even more interesting for a Juniper implementation is that Dust of Time lets us choose between several types of attractors (Lorenz, Chen...) : there are 2 chaos generators with separate X and Y outputs. the left encoder selects the type of chaos attractor, and the right controls the rate of movement. https://youtu.be/C-iisNg5O2Q
