oLv Demos

Info about oLv Demos

Projects with (OSC) utilize the oLvosc (and some oLvoscT) modules

ardourV1

OSC controller for Ardour DAW (OSC)

  • Sends OSC data on port 3819 (Ardour standard port)

  • Receives OSC data on port 8000

  • Set Reply port on Ardour:

    • Preferences->control surfaces->Open Sound Control->Show Protocol Settings
      • Control Protocol Settings Dialog -> Reply Manual Port: 8000
      • Also in 'Default Strip Types' Dialog check:
        • Audio Tracks
        • MIDI Tracks
        • Control Masters
      • In 'Default Feedback' Dialog check:
        • Strip Buttons
        • Master Sections
        • Play Head Position as Bar and Beat

  • Uses the oLvoscT threaded server

The 'Query' button should be pressed after starting (assuming Ardour is running). It will load the current tracks, and set Ardour to send it's data.

demoV1

Demo of many GUI elements including:

  • activate and deactivate elements (play with it)
  • switch between fullscreen and NOT
  • Size image, and use that to reset the viewPort
  • Various knobs, sliders, textboxes, droplists

hello1

Simple demo

hello2

Another simple demo

hellomin

A very minimal demo, maybe the most basic.

mkGui

mkGui is an on-the-fly, alterable GUI for pd2jack

  • When a new FX patch is loaded, it instructs oLvgui to build a custom GUI for it
  • Requires pd2jack (a headless version of Pure Data , built on libpd)
  • Needs it's own documention, which hasn't been done yet...
  • ...but the video demo shows how it works

mkGui, in many ways, was the reason oLvgui was made. It's a way to create interactive interfaces on mobile devices for audio effects.

oscCaster

Sends OSC test data to address, port (OSC)

  • Defaults set, but can be changed
  • Click on 'Send OSC Msgs' to open the port, begin send
  • Deselecting this closes the port
  • Select the frequency of the messages

oscMonV1

Monitors OSC messages on address, port (OSC)

  • Defaults set, but can be changed
  • Click on 'OSC Server' to open the port, begin capture
  • Deselecting closes the port

Uses 'oLvoscT', the threaded OSC server (LÖVE only) which is much more reliable for receiving OSC data packets.

panelXY

An OSC control surface that demonstrates a panel XY (2D control) element. Also showcases flipping the UI vertically.

  • Sends OSC data to Carla plugin host

themesV1

Themes is a color picker, and a theme color editor

  • Different preset themes can be selected in the Preset droplist
  • Move Presets to the color 'Quad' pallette
  • The palette can be set as the current theme
  • The buttons 'Print Color' and 'Print Palette Tbl' will output RGB tables that oLvgui can use
  • That color info is copied to the clipboard

tinaV1

tina is a tiny concertina-like instrument (OSC)

Like a concertina, tina is a two-handed performance instrument.

tina sends OSC data to a Pure Data script, which converts it to MIDI data -> which is routed to the softsynth of your choice.

tina has it's own documention...

  • tina is the most definitive demonstration of the panel element, and it's interactive capabilities
  • As noted, it uses Pure Data to convert the OSC data to a MIDI stream (and lessen the OSC network load)
