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.

gmorgan ~ Cross-platform Rhythm Station


gmorgan is a rhythm station, a modern organ with full editable accompaniment for play in real time emulating the capabilities of commercial rhythm stations “Korg”,”Roland”, “Solton” … also has a small pattern based sequencer like “Band in a Box”. Uses the capabilities of ALSA sequencer to produce MIDI accompaniment.

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.

Yoshimi ~ Linux Software Synthesizer


Yoshimi is a software audio synthesizer, originally forked from ZynAddSubFX. Follow the links in the header for help with downloading and running it. You can also check out the manuals for detailed help, and listen to examples of music created with Yoshimi. Once you have it all set up, here are just some of the features you will find:

  • Three separate engines, each with distinctive characteristics, can be used together or individually
  • Sixteen engine kits for the ultimate in multi-layering of engines, or for synthesized drum kits
  • Vector Control, manage up to four independent sounds on any channel with faders or an X/Y midi joystick
  • Solo step through up to 16 sounds seamlessly while playing in real time (including vector sounds)
  • Microtonal Tuning, Scala-compatible scales and keymaps
  • Extensive Midi-Learn, capture almost all internal controls and many switches with ordinary 7-bit values, or NRPNs, or even 7-bit NRPNs, then edit the responses
  • Command Line Access, headless operation and high accessibility, for those with sight- or motor control issues
  • Rich variations of tone and timbre, Yoshimi provides the means to ensure no two notes are ever identical – just like in the real world

hypercyclic ~ LFO-driven, MIDI-mangling Arpeggiator


What is hypercyclic?

  • an LFO-driven MIDI arpeggiator, gate effect and step sequencer
  • for mangling sustained MIDI input chords
  • the output of which can then drive other MIDI instruments
  • acts either as a VST or Audio Unit plugin for your DAW, or as a standalone application
  • the original hypercyclic won 2nd place in the KVRAudio.com Developer Challenge ‘07
  • the sweet spot for hypercyclic is the narrow border between chaos and regularity. Or, in other words, how to induce a certain pleasant randomness and syncopation, yet forcing everything to align again on the bar or beat boundaries

How do you use it?

  • the main use for hypercyclic is to generate midi that can be recorded and/or sent to other plugins. However it also features a simple built-in synth for testing purposes
  • you can use two tempo-synced LFOs to modulate various parameters for creating interesting rhythmic effects and chord variations
  • a unique feature is the possibility to modulate the sequencer step size itself, which is useful for creating glitchy stuttering effects
  • another thing you can use is a groove function for playing slightly off the beat. The groove parameters can also be modulated over time by the LFOs, adding to the rhythmic variation
