Mod-ui python function.py

• Mod-ui python function.py contains information about obtains pedalboard data
• Example mod-ui pedalboard structure.json is an output example of Mod-ui python function.py. It contains
  • connections: List of connections
  • plugins: Plugins instances informations

An option for creatint the json is creating a simple plugins-manager script.
Obtain data from plugins from the library plugins manager will avoid work on writing the json structure, which requires the minimum and maximum parameters and the order of the parameters.

plugins_json_path = 'plugins_data.json'

import lilvlib
import json

with open(plugins_json_path) as file:
    json.dumps(lilvlib.get_plugin_info_helper(''), file)

from pluginsmanager.model.lv2.lv2_effect_builder import Lv2EffectBuilder
from pluginsmanager.model.pedalboard import Pedalboard

pedalboard = Pedalboard('Name')

builder = Lv2EffectBuilder(plugins_json_path)
effect = builder.build('<effect uri>')
pedalboard.append(effect)
reverb.params['<param symbol string>'].value = param_value

# Generate json
print(pedalboard.json)

Note: Lv2EffectBuilder requires plugins_data generated by lilvlib
