- The SWS / S&M extension - a collection of features that seamlessly integrate into REAPER, the Digital Audio Workstation (DAW) software by Cockos, Inc. It is a collaborative and open source project. A bunch of actions: Filter REAPER's action list with "SWS"! The Snapshots window allows you to save selected track parameters for recall later. The Resources window is a versatile tool, but its main job is to let you fill your own "slots" of projects, track templates, FX chains, media files, etc. Just fill some slots and filter the action list with "Resources"! Groove tool is for quantizing audio and MIDI: learn a groove from an item and apply it to other items! Cycle Actions - Make special/advanced actions that perform sub-actions successively, or offer conditional statements, or etc. Marker actions allow you to place any action as a marker, and have that action ran when the play cursor crosses over that marker. Tempo manipulation and warp grid allows you to do extensive tempo manipulation and tempo mapping. If that's not enough, you can also freely warp grid using nothing but mouse. Anaylze and normalize loudness using the tools fully compliant with EBU R128 Loudness Recommendation. Power up your mouse usage with contextual toolbars. Show different toolbar at mouse cursor for each part of the interface. ReaConsole is a keyboard command interface for common track tasks. Notes window allows you to write custom notes for projects, tracks, etc but also for marker and regions. They can follow playback too (subtitles, lyrics, etc). Region playlist (non-linear play), Live Configs (for live performers: use REAPER like an FX pedal), additional zoom features, project management, color management, automatic colors/icons, LFO generator, cue buss generator, easily previewing and playing takes at mouse cursor, custom mouse cursors, etc.

Mids: Can only use own plugins, makes it fast.
Cons: UI could do with some polishing.
- send volume control
- when renaming, keep item name border even when mouse not over, pressing enter finishes renaming
- when copying an item, ctrl-v to paste it in the original track
- when drawing a sequencer item, click drag release for length
- when adding a sequencer sound item, highlight the beat it will be added at
- ctrl mousewheel up and down for horizontal zoom in and out
- note length?
- click track/metronome
- double click on stop = panic

Zrythm is free software licensed under the GPLv3+ and its source code is available on GitLab.
- Non - powerful enough to form a complete studio, fast and light enough to run on low-end hardware like the eeePC or Raspberry Pi, and so responsive and reliable that it can be used live, the Non DAW Studio is a modular system composed of four main parts: Non Timeline, a non-destructive, non-linear audio recorder and arranger. Non Mixer, a live mixer with effects plugin hosting and advanced Ambisonics spatialization control. Non Sequencer, a live, pattern based MIDI sequencer, and finally, the Non Session Manager to tie together these applications and more into cohesive song-level units.
Non-intuitive - e.g. one has to manually type in other Non application commands to link them to a track session.
Menus close when you click on them, argh.
On start, must create an actual project (Project/New) to add tracks.
No GUI item to import audio files, must be dragged into track list.
Doesn't auto switch tracks to stereo mode when stereo wav is imported.
No master track, must be created and routed manually.
Channel strips needs to be manually (and externally) routed with other Non apps.....
- https://github.com/topisani/OTTO - An OP-1 inspired all-in-one synth/sequencer/sampler/recorder/more solution. The OTTO is a complete hardware and software solution, with synths, a sampler, effects, sequencers, and studio modules. It is heavily inspired by the OP-1, but takes some things in a different direction. The goal is to create an all-in-one portable device, that allows anyone to play around with electronic music. It shall be open and accessible, while maintaining the very constrained interfaces, necessary to really be creative.
The software is modular, with modules in six groups: Synths, drums, effects, modulation, sequencing, and studio. Each module has up to 4 settings, that can be controlled using 4 rotary encoders. Like the OP-1, the colours of the 4 rotaries corresponds to the colour of the option on screen that will be changed. Each module slot will be accessible from a single hardware button press. The software will be set up to run on a Raspberry Pi, with a small AMOLED screen, 4 rotary encoders, and around 20 buttons. This can then be built into any kind of enclosure, with or without a midi keyboard and other bells and whistles.

Modular synth tracker
- Beast - a music composition and modular synthesis application released as free software under the GNU LGPL, that runs under Unix. It supports a wide range of standards in the field, such as MIDI, WAV/AIFF/MP3/OggVorbis/etc audio files and LADSPA modules. It allows for multitrack editing, unlimited undo/redo support, real-time synthesis support, 32bit audio rendering, full duplex support, multiprocessor support, conditional MMX/SSE utilisation for plugins, precise timing down to sample granularity, on demand and partial loading of wave files, on the fly decoding, stereo mixing, FFT scopes, MIDI automation and full scriptability in scheme.
Does any other software have channel strip sequencing, piano roll, tracker, modular processing and mixer? Interface still needs work.
Requires the https://github.com/tim-janik/rapicorn GUI library to build.
Need to figure out how to get LDFLAGS='-llibpng12.a' (older libpng) to work properly.
- Radium - a music editor with a new type of interface - Tracker-like but with waveforms instead of hex codes). Compared to the normal sequencer interface editing is quicker and more musical data fits on the screen. However, despite its unusual appearance, it's a design goal for Radium to be straightforward to use, and easy to learn. It should not be harder to learn Radium than any tracker or most midi sequencers.

- Buzztrax - a free software project to create a clone of the Buzz music composer. The driving motivation is to preserve the playability of the compositions made with Buzz. 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 arrangment of virtual audio plugins that are linked together to create different effects. Each of these machines can be controlled realtime or via patterns in the sequencer.

Dead, forked to Neil Sequencer
- Neil is an open source application for making music on Linux. It is a kind of music software known as a tracker. It is similar to the famous buzz for Windows. Neil was forked off Aldrin project because it was not being developed smoothly enough and, since Aldrin was the only Linux application I could actually make music on, I wanted to secure it from being made unusable (for me at least, so no offense to original developers - you did a great job).
- https://bitbucket.org/bucket_brigade/neil/overview - mercurial (hg). last updated 2013.
- Buzz - the first ever "easy to use" free modular software based synthesizer. What this means is that the entire system is based on objects, which may be routed in a modular fashion, giving you the freedom to be as creative as you want. For example, if you wish to run 3 Physical Modelling synths and a Drum Machine through 2 seperate Stereo Delays, into a Mixer, through a Compressor and Parameteric EQ, and finally out to your speakers - no problem. Lay down your synths, connect the wires and you're done.
