The AT-327 Multimode Filter prototype demo

One of the clearest points where the archive shifts from bench work to presentable output: manufacturing complete, tuning done, and a first set of public demos strong enough to exceed expectations.

Manufacturing had wrapped, the modules had been tuned, and the first batch of demos suggested the range of sounds was even better than expected.

It also includes a small but revealing line about needing better photographs. That tension between circuit progress and presentation is all over the journal, and it is part of what makes the posts feel real.
