Best left to external modules: - CV-controlled clock. Presumably the CV in implement a DC offset via non-inverting op-amp. A CV in to pause the clock From 96e9dd144019309f3e33f1daf66ec448c4e2d994 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Add cascading input and output jacks working_height = height - v_margin - title_font_size*1.5; top_row = height - v_margin*2 - title_font_size; Experimenting with more representative footprint.
