The design and building process of io, and documentation of io’s construction.

analog io

By Han-earl Park | Published: June 29, 2009

I’ve assumed that future versions of io would have a single board computer (or multiple SBCs) in place of the clunky and fragile personal computer. There was, however, always an alternative. Take the not-so-humble analog computer, a technology with a fascinating past and a (still promising) future. Given that io’s behavior is driven by an [...]

beta test 11-10-08 & 12-08-08: resultant changes

By Han-earl Park | Published: March 25, 2009

Here’s a list of the significant changes. These address issues that Franziska Schroeder and Bruce Coates brought up during the testings in November and December respectively. Greater variation in output. Including pseudo-Braxtonian ‘separation’ implemented via interp tables. Implementation of a meta-banalyzer that shakes up the system depending on input variation. Greater variation in the VL70m [...]

bug fix: banalyzer+

By Han-earl Park | Published: March 24, 2009

Here’s a fix for a significant bug that I somehow didn’t catch (didn’t hear?) for several years. The side effect of the fix is that io is now significantly more responsive. \ banalyzer+ \ \ a "smarter" banalyzer class designed to works in conjunction with the \ parser classes. \ \ ob.banalyzer+ clears internal storage [...]

beta test 11-10-08: preamble

By Han-earl Park | Published: November 25, 2008

frankenmusic(s) Almost eight years ago, when io-to-be was a bunch of discorporate code fragments, Sara Roberts remarked that the enterprise of constructing a machine improvisers wasn’t so much megalomanic as Frankensteinian. Fifteen days ago, during the break between beta test sessions, Franziska Schroeder asked a pithy question that cut to the core of this enterprise: [...]
