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 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.
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
Giada is a free, minimal, hardcore audio tool for DJs, live performers and electronic musicians. How does it work? Just pick up your channel, fill it with samples or MIDI events and start the show by using this tiny piece of software as a loop machine, drum machine, sequencer, live sampler or yet as a plugin/effect host. Giada aims to be a compact and portable virtual device for Linux, Mac and Windows for production use and live sets.
Rosegarden is a music composition and editing environment based around a MIDI sequencer that features a rich understanding of music notation and includes basic support for digital audio. It’s an easy-to-learn, attractive Linux application that is ideal for composers, musicians, music students and small studios or home recording environments.
Frinika is a free, complete music workstation software for Linux, Windows, Mac OSX and other operating systems running Java. It features a sequencer, soft-synths, real-time effects and audio recording.
OpenSebJ is a free real time audio sample mixer that runs on Microsoft Windows. The source code for OpenSebJ is released under the GNU General Public License.
Supports loading of 255 audio samples, in wav format, which can be played in real time.
Sample properties such as volume, pan and frequency can be adjusted individually for each sample. (even during mid-play)
A composition tool is provided and presented in a familiar multi-track sequencer environment. Looping compositions are also supported.
Samples can be linked to keys on a keyboard and triggered in real time when a key press occurs.
Each sample can also have the play cursor position adjusted while the sample is playing, to provide a virtual needle to be moved.
Stream to disk recording, allows all audio played from OpenSebJ to be saved.
Pitch shifter roll, allows an order to be set up, so that each time a sample is played, the next pitch shift in the sequence is undertaken before the sample is played. i.e. set up a sample to key ‘1’, then set up a pitch shift sequence, high, mid, low, higher, etc. (using frequency values which are transposed onto screen ‘ranges’ to allow easier utilization).
Qtractor is an Audio/MIDI multi-track sequencer application written in C++ with the Qt framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio, and the Advanced Linux Sound Architecture (ALSA) for MIDI, are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
