Plugins/ResourcesFree and/or open source resources including a curated list of cross-platform plugins
I started this list of free and/or open source resources, including a curated list of cross-platform plugins, for my students as an exploration of options to to make Reaper more comparable to substantially more expensive software packages. I thought other people might find it helpful.
This list is in no way intended to be comprehensive, but curated to focus on mostly free and/or inexpensive resources for professional computer-based music production that are:
- High quality (plugins that work well and as expected, do not crash, reputable companies).
- Cross-platform (MacOS and Windows, at least).
- Resources to be used by my students.
It began as multiple course documents and part of my Why Reaper? discussion—which has as stated one of the goals of adding free, cross-platform functionality to Reaper out of the box to make it more comparable with other more expensive commercial digital audio workstation (DAW) packages. At the same time, to create awareness of options that might make it more accessible for students to work at home (or coffeehouses, libraries, parks, breaks on their night jobs, etc.) with differing OSs, new or old laptops, and differing levels of discretionary income.
Some notes are from my ensembles, programming, composition, and other courses teach or have taught. I have also drawn from an instructional resources document I helped develop with my colleague Dr. Eric Honour in response to the COVID-19 pandemic and the sudden movement to online instruction.
This page continues to be updated regularly, so check back.
Also: please feel free to contact me if any plugins on the list are deprecated, or if there are some (professional quality, cross-platform, free) that you recommend.
DAWs and Production
Reaper is my go-to DAW. It is professional, cross-platform, fully functions in demo mode, and is reasonably priced. To continue using in demo mode you just need to click the “Still Evaluating” button. They are a very generous company: the demo does not expire. We love it. If you do as well, and are financially able, please buy a license after you've used the demo for a while.
- I put together a list of reasons to use Reaper at this link.
- Check out our combination of text and video-based tutorials, Two-Minute (Or So) Tutorials For Reaper DAW
- For more extensive longer form tutorials, if you have more time on your hands, we highly recommend This is REAPER 6
- And download Reaper DAW at http://reaper.fm/
Ableton Live is required for my Tech Performance students and New Technology Ensemble members. There is a free “lite” version that works great and comes bundled with MIDI controllers and other hardware. Focusrite, Novation, Akai, Native Instruments, and many others include a free bundled license for Ableton Live Lite.
- Ask around, a friend who purchased a controller might have an extra license on one of their accounts.
- Academic pricing is available for Standard and Suite, 40 percent off. No educational price for the Intro version.
- I love Ableton Live and use it regularly, check out my M4L plugins under Max/Software and KaiGen.

Notation and Composition
For mind-mapping and organizing compositions:
Lucidchart.com formerly my first choice, however their stripping away of free features on the academic version bothers me. I still like it for integration with Google docs et al.
Milanote.com is very slick! Nice integration across phones, tablets, desktops, web on free version. Good mind mapping features as well: https://milanote.com/product/mind-mapping. The only caveat, limited to 100 cards on free version (which is really quite a few) and pricey subscription to add features.
Freemind is excellent and open source, but looks a bit dated.
Draw.io is nice for integration with Google docs. In addition to mindmapping, good drawing tools as well.
Musescore is cross-platform and free. It works great for standard notation.
Flat.io: For purely online, standard notation. Many students use it for collaboration.
For people interested in more advanced/complex environments that have a higher learning curve, but that are also free:
For adding graphic elements, Inkscape is an open source graphic environment offering "a rich set of features and is widely used for both artistic and technical illustrations such as cartoons, clip art, logos, typography, diagramming and flowcharting." Similar to Adobe Illustrator. It is more clunky than Illustrator, but has a nice price point: free.
