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 […]

beta test 11-10-08 with Franziska Schroeder

By Han-earl Park | Published: November 5, 2008

The first beta test (which, in some respects, is more of an alpha test) is scheduled to start on Monday, November 10th 2008. Saxophonist, improviser, theorist and veteran of technological arts, Franziska Schroeder will be working with io++ (or components that will make up that machine), and we’ll see more clearly what work needs to […]

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 […]

rack wiring: 8-pin mini DIN angst

By Han-earl Park | Published: October 22, 2008

Almost completed the wiring of the rack (except the patch panel foot switch connectors which I am leaving for the moment). No problem with the XLR connectors, quarter inch phones, MIDI cables, barrel connectors… then I hit a major snag with the 8-pin mini DIN panel socket for the Mac serial connector. Too small, too […]
