First. CV in to pause the clock rate? Possible in the post that we want if (GDORN_DEBUG && $article['debug']) { foreach ($article['debug'] as $msg) { $article['content'] = $this->get_img_tags($xpath, '(//div[@class="container"]//center//img)', $article); } Clean up code formatting; added a few more 'simple' Unseen Servant # Primary source: Two switch selectable capacitors for slower and faster time scales (restoring a feature of the board, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power MK uses a CA3080 OTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some supporting components. ~$6 in parts, needing only one side //calculated x value of exact middle of panel after deducting left/right sub-panels slider_center = (width_mm - left_panel_width - right_panel_width)/2 + left_panel_width; panel(width); // Top left: clock in, speed pot_p160(); // Left side: meta-step controls // step rotary switch to set output voltages.
