Offset via non-inverting op-amp. A CV in controls the clock Add CV (and knob) controlled glide to schematic Add CV in that pauses the clock oscillilator an external clock. One idea: add a global/master pitch control/modulation function with a hair of margin // margins from edges h_margin = thickness*2; v_margin = hole_dist_top*2; output_column = width_mm - thickness*2; From 88bf85725f2c856b6f99f99568e61e08e1060d3b Mon Sep 17 00:00:00 2001 Subject: [PATCH] Documentation, some cosmetic sh/PCB updates Docs/precadsr.pdf | Bin 0 -> 46787 bytes Datasheets/tl074.pdf | Bin 10174 -> 0 bytes From 06850ab67823ca6e309908fccf0dcf41bca709a5 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Footprint selection, some PCB layout choices From c6741b48f0ef8a6e69ecbca1a47bc4f4b481e2a3 Mon Sep 17 00:00:00 2001 Subject: [PATCH] tracks the ratsnest and compactifies the power subsystem From 9db3fb2a68fdc178fb3f74c68d22940f6cdd2e78 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Current draw 12 mA +12 V, and sustain voltage is taken from \npot pin 1.
