Hothouse gen~ programming

[fbotello]

Hi I was wondering if anyone has been able to program the pedal with gen~ ? I see there's pd/plugdata support and am wondering what it might take to get that going. I teach and program mostly in Max so it would be extra rad to be able to do this.

Hey there! Sorry for the delay. I know of several people that have programmed the Hothouse with Max / gen~, however, they haven't shared many details of the process. As for myself, I can barely spell gen~ 😁 I honestly know next to nothing about it.

What I can tell you is that people were able to use the hothouse.json file found in the pd examples directory to get things working. At least one person said they made some minor modifications to the LED definitions, so it ended up looking like this:

{
    "name": "hothouse",
    "som": "seed",
    "audio": {
        "channels": 2
    },
    "components": {
        "fs1": {
            "component": "Switch",
            "pin": 25
        },
        "fs2": {
            "component": "Switch",
            "pin": 26
        },
        "sw1_up": {
            "component": "Switch",
            "pin": 9
        },
        "sw1_down": {
            "component": "Switch",
            "pin": 10
        },
        "sw2_up": {
            "component": "Switch",
            "pin": 7
        },
        "sw2_down": {
            "component": "Switch",
            "pin": 8
        },
        "sw3_up": {
            "component": "Switch",
            "pin": 5
        },
        "sw3_down": {
            "component": "Switch",
            "pin": 6
        },
        "knob1": {
            "component": "AnalogControl",
            "pin": 16
        },
        "knob2": {
            "component": "AnalogControl",
            "pin": 17
        },
        "knob3": {
            "component": "AnalogControl",
            "pin": 18
        },
        "knob4": {
            "component": "AnalogControl",
            "pin": 19
        },
        "knob5": {
            "component": "AnalogControl",
            "pin": 20
        },
        "knob6": {
            "component": "AnalogControl",
            "pin": 21
        },
        "led1": {
          "component": "Led",
          "pin": 22
        },
        "led2": {
          "component": "Led",
          "pin": 23
        }
      },
    "aliases": {

    }
}

Let us know if you get it working. I would love it if someone such as yourself were to write up a wiki page on it!

Cheers.

Hi,

I started to work with gen~ on the Hothouse, and it works splendidly! Yes, one has to use the modified hothouse.json (with the led1/led2 instead of cvouts), but there is a small issue in that the polarity of the leds are reversed. Sending a 1 turns the led off, sending a 0 turns it on. Everything else works as expected. Took me a while to find out, but then it all worked like a charm.

I just got it working in Max 9, as well. The gen~ examples provided by Electro-Smith are pretty limited in function for a guitarist like me. One item for folks to understand is that any Params defined in the gen~ patcher can be mapped via the json above via the alias section. For example, using the Dattoro Reverb, dattoro.maxpat, there is a set of parameters defined in Max:

you can map those to the controls you want to use via Alias in the json file:

In that Max image, you see the bottom left box with the blue "browse" button. That is how you locate the json file. And the bang button to the left will compile and send to the pedal (in bootloader mode).

Like the other Electro-Smith sample maxpats I've looked at, there are "foot switches" for turning stuff off/on (cause it's intended for eurorack system generally).

I put my json file (on Windows) at ...users/username/documents/Max9/packages/oopsy/source folder and all seems to work fine.

A collection of excellent sounding guitar pedals for the daisy seed is here: https://idmnyu.github.io/IDMPEDALS/pedals.html. Pretty much everything a guitarist does, plus a few things like comb filters and such.

These are made in 2021/22 as part of a class Luke Dubois taught at NYU. They were made for the Daisy Petal, but they're easy to port as the Petal also had 6 knobs. It took me just a few minutes each to test them out on the Hothouse. Remember, though, the LED's polarities are switched.

P.S. Luke is fine posting them here, if you repost credit Luke Dubois NYU Integrated Digital Media Program (IDM).

BTW, the LED Polarities are NOT inverted on the HotHouse. However, the Oopsy coded config defaults are inverted (for reasons I don't know).

The way to fix this is to add "invert": "false" for each led in the json:
"led1": {
"component": "Led",
"pin": 22,
"invert": "false"
},
"led2": {
"component": "Led",
"pin": 23,
"invert": "false"
}

Ah, thanks. If that's the case, there's not much to do to convert Luke's patches. The Petal had 6 knobs anyway. Right now the main difference is that one needs to rename the param objects, or even put Luke's names as aliases into the JSON. I could write a roadmap for anybody converting a pedal. Hans
