Your one-stop shop for all things Aaron Giles!

I am a freelance Seattle-area programmer, musician, web developer, and sometimes graphic designer. I have at various times worked for Microsoft, Connectix, LucasArts, and have a long history of creating free software and other stuff.
See my programming page for detailed work history.
I am also an active musician, singing in several local groups and tinkering with the lute. See my music page for more details on what I’m up to musically.

If you’d like to stay up to date with my current projects and activities, there are a few options:

| Project Name | Description | Status |
|---|---|---|
DREAMMA |
A universal emulator for classic LucasArts games, from the original SCUMM adventures, to the various flight sims, to early 3D games, and everything in between. Builds available for Windows, MacOS, and Linux! | Latest stable release is version 3.0.3. Already working on plans for a follow-up! |
ymfm |
A BSD-licensed open source library, written in C++17, with highly accurate emulators for Yamaha’s famous FM-based synthesis chips. Supports OPM (YM2151), OPN (YM2203), OPL (YM3526, YM3812, YMF262), OPLL (YM2413), and OPZ (YM2414), along with many variants. | In active use in MAME, DefleMask, and other projects. Occasional bug fixes still happening. (Postcardware) |
postcardware.net |
A site documenting the 6000+ postcards I received for my shareware program JPEGView back in the mid-1990s. Follow postcardbot on either Mastodon or BlueSky for random postcards 3 times a day. | All postcards scanned, over 5000 tagged; bot posts them 3×/day. Search interface now works! |
rehearsaltracks.net |
A JavaScript and WASM-based site for interactively learning vocal parts in choral music, using my own SoundFont library for realtime playback. | Opportunistically adding new works; more features pending further interest. |
Summer Fling Singers |
A summer choral group that I started in 2016, performing once each year in August (pandemics permitting). We officially became a non-profit in 2019, and I currently serve as board president and artistic director. | Our 2024 season, Lifecycles, is complete! |
Greater Seattle Choral Consortium |
A great organization that helps Seattle-area choral groups connect with each other and with the community. I served on the board of directors for 8 years, 5 as treasurer, and continue to run the website. | Website maintained! |
