Autocomp attempts to generate simple bass/drum/keys accompaniment parts from chord sheets, suitable for practising with. It takes as input a text file containing chord changes, plus time signature and bpm information, and outputs a csound .sco file containing a simple arrangement of those changes. A sample .orc file containing a bass instrument, a selection of keyboard instruments and
a small sample-based drumkit is provided.
Drum count is software to count drum hits in real time. It's a useful practice tool for drummers, and is easy to use.
Gneutronica is a MIDI drum machine software for linux with a gnome based user interface to allow easy creation and play back of drum tracks to external MIDI devices
Hydrogen is an advanced drum machine for GNU/Linux. It's main goal is to bring professional yet simple and intuitive pattern-based drum programming. Features include: Graphical user interface based on QT 3, Sample based audio engine, Oss Audio driver
JTrigger is a sample player/drum machine intended for use with hardware trigger pads, but it works fine with any sort of external MIDI sequencer as well. It supports up to 2048 samples, has velocity sensitivity, and can load anything supported by libsndfile. It attempts to keep resource usage low.
The LDRUM is an open-source drum machine that offers ten channels, realtime control, a simple pattern sequencer and a graphical user-interface. It currently runs under Linux only, it is developed in C++ and uses JACK, ALSA, Qt and LADSPA (it's a JAQL app;).
