MIDILights 1.1

I just uploaded a new version of MIDILights for your perusal. It’s now got support for using MIDI controllers to affect luminosity, hue and whatnot.

I also included a separate composition called MIDINotes, which is the macro patch I use to determine the note played, since QC makes that really hard. It doesn’t give the actual MIDI note, just 1-12 (C-B), or 0 if off. The “velocity” resembles actual velocity, but it’s not correct if you’re playing multiple notes at once, so beware!
I also removed the standalone executable – with QC’s crappy MIDI implementation (you have to choose the MIDI input inside the composition, rather than it taking a default and running with it), it probably didn’t work for anyone but me, or maybe someone else who ran MIDIkeys before starting it up. I may take a stab at doing some kind of CoreMIDI-based implementation, but it won’t be any time soon.

download it here.

Announcing – MIDILights

I’ve finally finished a Quartz Composer composition that I’m comfortable sharing with the world. It’s a rendition of the clavier à lumières, a kind of light organ from 1915. As MIDI notes come in, it renders the QC view in the appropriate color for the note. So if you’ve been wanting to do a version of Scriabin‘s Prometheus: Poem of Fire, this will come in handy…
It’s nothing too fancy, other than the painstaking process I had to use to get something approximating a MIDI note number from QC. I may post about that later. Check it out and download it here, free.

Update: Download link was b0rken. I’ve fixed it, and as a bonus, added a standalone .app version for those who haven’t installed the OS X Developer Tools. Many thanks to SteamSHIFT for pointing out the brokenness.
