Carla ~ Cross-platform Plugin Host


Carla is a fully-featured modular audio plugin host, with support for many audio drivers and plugin formats. It has some nice features like transport control, automation of parameters via MIDI CC and remote control over OSC.

Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2, VST3 and AU plugin formats, plus SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA, DirectSound or CoreAudio.

There are 4 types of engine processing:

  • Single-client: (JACK driver only)
    Same as Multi-client, except that all JACK ports belong to a single master client.
    This is needed when a setup doesn’t support multi-client JACK apps, such as LADISH.
  • Multi-client: (JACK driver only)
    Every single plugin is exposed as a new JACK client. Audio and MIDI ports are registered as needed.
  • Rack:
    Plugins are processed in order, from top to bottom.
    Plugins with non-stereo audio channels are not supported, but a forced-stereo option is available for Mono ones.
  • Patchbay:
    Modular patchbay mode, just like in JACK Multi-client and many other modular applications.
    Every plugin gets its own canvas group and ports allowing you to interconnect plugin audio and MIDI.

Triple Cheese ~ Cross-platform Synth


Triple Cheese: Luscious and cheesy, winner of the 2006 KVR Developer Challenge, is a truly unique freeware synthesizer. No traditional oscillators or wavetables, no FM or phase distortion and no analogue modelled filters here. A touch unusual and a little cheesy, Triple Cheese is quite capable of some surprising sounds.

Triple Cheese avoids classic synthesis techniques—no subtractive, frequency modulation (FM) or additive synthesis. Rather, it employs various types of comb filter, often in series, to generate and modify sound. Think of the comb filters as very short chromatically tuned delays. Three modules are arranged in series and either generate their own sound, or process the output of the previous module.

The features for each module can result in sounds that might seem a little “cheesy” or retro (think early 1980s digital synths). But when pushed, you will find Triple Cheese creates some surprisingly lush sounds.

  • 8 different modes per comb filter module (11 modes total)
  • Polyphonic (up to 16 voices), duophonic, monophonic (retriggered) or legato mode
  • VCA with amplitude modulation, pan
  • Skinnable User Interface
  • 170 factory presets

Seq24 ~ Minimal MIDI Sequencer


Seq24 is a minimal loop based midi sequencer. It was created to provide a very simple interface for editing and playing midi ‘loops’. After searching for a software based sequencer that would provide the functionality needed for a live performance, such as the Akai MPC line, the Kawai Q80 sequencer, or the popular Alesis MMT-8, I found nothing similar in the software realm. I set out to create a very minimal sequencer that excludes the bloated features of the large software sequencers, and includes a small subset of features that I have found usable in performing.

foo_osd ~ Foobar2000 On Screen Display


This component provides configurable screen overlays which may be opened with hotkeys, or appear on specific events. Each overlay is configured separately, and has its own set of events.

hydrogenaud.io/index.php/topic,43044.0

foobar_osd (On-Screen Display) is a foobar2000 component that shows track information as a floating overlay on your desktop during playback events.

Instead of opening the player window to see what’s playing, foobar_osd displays relevant information directly on your screen.

Typical uses include:

  • Seeing track information when the player is minimized
  • Monitoring playback on multi-monitor setups
  • Getting quick visual feedback without interrupting workflow
  • Displaying detailed metadata beyond basic notifications

Unlike standard operating system notifications, foobar_osd is fully customizable using foobar2000’s powerful title formatting system.


Core Features

When triggered, foobar_osd can display:

  • Artist and title
  • Album name
  • Track position and duration
  • Album artwork
  • Custom metadata fields
  • Technical playback information

The display appears briefly and then fades away automatically.


Event-Based Display

You control when the OSD appears. Common trigger events include:

  • Track change
  • Play or pause
  • Stop playback
  • Manual trigger via hotkey

Careful selection of events is important to avoid excessive on-screen interruptions.


Fully Customizable Text Formatting

One of the strongest features of foobar_osd is that it supports full foobar2000 title formatting.

This means you can display virtually any tag or metadata field stored in your files.

Example format:

[%artist% - ]%title%
%album%
$if(%album_avg_bpm%,Album BPM: %album_avg_bpm%)

Conditional formatting allows the display to remain clean by only showing information when available.


Installation and Access

After installing the component:

  1. Restart foobar2000.
  2. Open:
Preferences → Tools → On-Screen Display

All configuration options are available in this section.


Appearance and Layout Options

foobar_osd allows extensive visual customization:

  • Background transparency
  • Font selection
  • Fade animations and display duration
  • Monitor Selection
  • Shadow effects
  • Screen position
  • Text size and color

Using foobar_osd Effectively

Many users install foobar_osd but never use its full potential. The following strategies significantly improve usability.

Display Meaningful Metadata

If your library uses structured tagging, include useful fields.

Example:

[%artist% - ]%title%
%album%
$if(%album_avg_bpm%,Album Tempo: %album_avg_bpm% BPM)
$if(%genre%,Genre: %genre%)

This transforms the overlay into a quick contextual information panel.

Create Minimal or Informational Layouts

Depending on your workflow, consider:

  • Minimal layout — artist and title only
  • Informational layout — album, metadata, technical details
  • Radio/stream layout — include station information or bitrate

Use a Manual Hotkey

Setting a hotkey to manually trigger the OSD is extremely useful.

Advantages include:

  • Quick track info lookup without switching windows
  • Clean desktop experience without persistent UI elements

Use Conditional Formatting

Conditional statements prevent empty lines or clutter:

$if(%album_avg_bpm%,Album BPM: %album_avg_bpm%)

Only displays when the tag exists.

Time Functions:

Elapsed / Percent / Duration / Remaining

$puts(Elapsed,$if(%isplaying%,$pad_right(%_time_elapsed%,5,0),00:00))
$puts(Duration,$pad_right(%length%,5,0))
$puts(P,$muldiv(%_time_elapsed_seconds%,100,%_time_total_seconds%))
$puts(Percent,$if(%isplaying%,$if($greater($get(P),99),99,$pad_right($get(P),2,0)),00)'%')
$puts(Remaining,$if(%isplaying%,$pad_right(%playback_time_remaining%,5,0),$get(Duration)))
$get(Elapsed)  |  $get(Percent)  |  $get(Duration)  |  $get(Remaining)

Lazy Kenneth ~ Bass Mixing VST


Lazy Kenneth will help those who don’t know how to use, or are too lazy to use sidechain to handle heavy basslines that collide with the bass drum in 4/4 music. That is music where you put a bass drum on all fours, techno, house, trance, minimal, tribal and so on. Put Lazy Kenneth on the bassline track and it will automatically duck the signal when the bass drum hits. You could place a LK on all tracks except the bass drum for some real heavy pumping effect.
