        The H9000 has a C/C++ plugin API used in collaboration with Cycling 74 to make plugins from Gen that run on the H9000. If you would like to utilize this, email support@eventide.com to have your Cycling '74 account registered.

        ===================================================

        This algorithm is my edit of Peter Mculloch's Gen port of a version of the Moog ladder filter originally created at the Zurich University of the Arts by Beat Frei. It is 96kHz-compatible, but you'll have to scale the frequency parameters appropriately.. Here it is in action: https://etide.io/RGeof

        in1 & in2 are summed, then split through a crossover (made by Graham Wakefield) whose frequency is set by the xovr_Hz parameter. The lows are effected by amplitude modulation, and the highs are effected by ladder filter frequency&resonance modulation. You will have to find/create your own audio-rate LFO to run these three modulation inputs.

        • in3 Low amplitude (0 – 1)
        • in4 Ladder frequency (0 – 1)
        • in5 Ladder resonance (0 – 1)

        • out1 lows
        • out2 highs

        • out3, 4, and 5 are the same as the inputs, except these outputs approach 1 as the dry_wet parameter goes from 100 to 0. These signals can be useful for controlling audio-reactive visuals.

          This is very interesting!  I do not have a Cycling 74 account but if this makes me want one! Is this a more user friendly or feature rich approach to WYSIWYG editing than Vsig?   Currently just missing. ‘Containers’ or ‘Macros’ in Vsig for my usage. Otherwise it seems pretty great.

            Great info, Thanks John!  I’d like to look into this as time allows.  I should say, it really would be nice to have container modules in Vsig!   🙂

              Glad to help!

              Vsig 2.0 has Supermodules, but they haven't made it into Vsig3 yet. Page 56: http://www.eventidier.com/pdfs/vsig20.pdf

                Is there an estimate of timeframe for when the supermodule will be available, and whether a user can optionally protect a supermodule?

                I used to do a lot of modelling in simulink and this functionality was invaluable, particularly when models got complex or had repetitive sections.

                  No sir.

                  Max/MSP has this functionality too and I agree that it's super useful.

                    Max/MSP calls those "abstractions" https://docs.cycling74.com/max8/tutorials/basicchapter15 keep in mind that these tutorials, while viewable online, are more useful when viewed in Max/MSP's reference window.

                    With Max/MSP, you can listen to your patch as you build it. If you go to the Max/MSP menubar and click "help > reference > Gen > Topics > Gen" you'll find many useful snippets. The main benefit of Vsig is that you get to use proprietary Eventide modules such as the reverbs, delays, pitchshifters, oscillators, filters, and soon-to-be-functional transient_split. Plus you can download 1000 examples from the H9000.

                    fun facts: vsig has about 258 modules. gen has about 156 objects.

                    I should also mention that this requires Max/MSP, which has a 30-day free trial: https://cycling74.com/downloads
