So I realize this is probably one of those things where you'll either be like meh, or ooh cool, but here's another thing I've been working on, mainly for my own personal use and a group of friends than anything, but I figured wtf, someone else here might enjoy this. This is #FastPlay, a little media player that I've been working on. It's not and will never be a full replacement for Foobar2000, and thus lacks things such as a converter and a media library, but has enough features I think for it to still be useful. It supports being able to be set as the default for formats, for example. I'll paste a bit from the readme here which explains what's unique about FastPlay: At the core of Fastplay are what we will call virtual sliders. Right now, there are two of these virtual sliders.
The first one adjusts things like your volume and any effects you choose to enable/add. You choose what this slider adjusts by using left and right brackets, and then adjust the value itself with up or down arrows.
The second slider allows you to do things such as seek and move between tracks. You adjust what this slider does by using comma and period, and you adjust the slider with left and right arrows.
You can choose what shows up in these sliders by heading to the options dialog, control comma.

@Bri Hi. Re: Fastplay. I am wondering if it is possible to implement a keystroke to set the effect currently in focus back to the default value, e.g. 100%? Also, there are numerous references to enablement of M4B throughout the settings dialog in the latest version, under most of the tabs. Thanks.
@sjtaylor Backspace.
@Bri Thank you!
