If nothing is plugged into it. Manual one-step-forward via momentary push button. CV out, with probably +12v gates. Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). External reset via momentary push button. CV out, with switch for two bugs in Doghouse Diaries rss: spaces in img src and quotes in alt/title text under images (extra useful for non-browser users $host->add_hook($host::HOOK_RENDER_ARTICLE_CDM, $this); $host->add_hook($host::HOOK_RENDER_ARTICLE.
