By Han-earl Park | Published: July 1, 2009
Source code for io 0.0.1 beta (rev. May 12th 2009) [86kB zip file]. There have been major changes since 03-23-2009 as a result of the beta tests with Bruce Coates and Franziska Schroeder. These changes are unfortunately not documented/commented at the moment, but I’m uploading the source files for the record.

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: [...]

hp->midi early report

By Han-earl Park | Published: November 7, 2008
One area in which I’ve been concerned with the question of optimization vs. elegance is in the hp->midi word (a ‘word’ is Forth parlance for function / procedure / subroutine). This word takes the hp_ values (with a range of -hp_range/2 to hp_range/2), which io’s cognitive innards generate, and translates them into legal MIDI control [...]

software optimization vs. elegance

By Han-earl Park | Published: November 4, 2008
When started writing what became io 0.0.1 beta in ’99, having thrown out a whole bunch of old material, I made an effort to write elegant code. This was partly because of the complexity of this project (which would end up in the region of 25,000 lines of code), but also a reaction to the [...]
