QMidiArp ~ MIDI Arpeggiator & Phrase Generator

Posted by tom2tec on

QMidiArp is a MIDI arpeggiator, phrase generator and controller LFO for ALSA and JACK. It can run multiple synchronized arpeggiators, LFOs and step sequencers. The modules are also available as LV2 plugins with Qt user interface. QMidiArp has been growing since June 2009 on top of Matthias Nagorni’s original arp idea.

Features:

  • Programmable arpeggio patterns, LFO waveforms and sequences
  • Modular setup of arpeggiators, MIDI LFOs and step sequencers
  • MIDI-controllable (MIDI-Learn)
  • Synchronization with MIDI Clock or JACK Transport possible
  • Optional triggering by keyboard or continuous play mode for all modules
  • Patterns can be stored and switched by MIDI control while running
  • JACK MIDI or ALSA MIDI backends
  • Modules available as LV2 Plugins

JJazzLab ~ Generate Backing Tracks

Posted by tom2tec on

JJazzLab is a Midi-based application dedicated to backing tracks generation. You type in chord symbols, select a rhythm (style), then the application generates a complete backing track with drums, bass, guitar, piano, strings, etc.

The objective is to generate intelligent and interesting backing tracks, i.e tracks which are:

  • realistic
  • non-boring (with variations)
  • easily customizable, even for complex songs

Buzztrax ~ All In One Music Composer

Posted by tom2tec on

Buzztrax aims to be a music studio that allows one to compose songs using only a computer with a soundcard. If you’ve used tracker programs like FastTracker, Impulse Tracker, or the original AMIGA SoundTracker, that will give you an idea of how one can sequence music in Buzztrax.

The Buzztrax editor uses a similar concept, where a song consists of a sequence with tracks and in each track one uses patterns with events (musical notes and control changes). In contrast to other Tracker programs, tracks are not simply sample players: a user can make a song using an arrangement of virtual audio plugins that are linked together to create different effects. Each of these machines can be controlled real-time or via patterns in the sequencer.

CheeseTracker ~ Sampler & Sequencer

Posted by tom2tec on

CheeseTracker is a software sampler and step-based sequencer. It allows a musician to turn single-note samples into instruments capable of covering three or four octaves (by playing the samples at different speeds, resulting in different pitches). In addition, it is possible to take a collection of samples that are recorded at different octaves, and combine them into a single “instrument,” allowing for even more octaves without sampling artifacts.

Using the Pattern Editor, it is possible to compose songs with these instruments that the computer plays automatically. The Pattern Editor allows the user to arrange samples in several independant channels, so that many samples can play simultaneously. These songs, and the samples which comprise their instruments, can be saved together in one-file archives called modules.

CheeseTracker imposes no limits on the length of the samples used. As a result, it can be used as a mixer as well as a sampler/sequencer. Effects such as reverb can be applied to each sample individually, eliminating the need for expensive pedals.
