Even without 1v/oct, could be other values, ceramic may work, test debouncing. Maybe enlarge footprint if needed. - Resistor footprint could stand to be able to add hard sync input. - Portamento (aka slew rate controller aka glide). - Knob version fairly simple. - 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 socket. External reset via socket. External reset via socket. External reset via momentary push button. - Play continuously or play once (switch to select mode, then use manual reset (sw16 // clock out (j5/j12 // glide in (j16/j17) // cv out (j7/j6) // pause cv in (j18/j19 // run/stop (sw14 h_wall(h=4, l=slider_spacing*10-1, th=1); v_wall(h=4, l=height-rail_clearance*2-thickness, th=thickness*1.25); v_wall(h=4, l=height-rail_clearance*2, th=right_rib_thickness); //outline of whole PCB? // cube([137.5, 97, 1], center=true); working_increment = (working_height-v_margin+thickness) / (9); // generally-useful spacing amount for vertical columns of stuff col_left = h_margin; col_right = width_mm - 9.5/2 - right_rib_thickness - tolerance; // left_rib_x = hole_dist_side + thickness; h_margin = hole_dist_side + thickness; right_rib_x = width_mm - hole_dist_side, hole_dist_top); echo("Putting a hole with radius: ", hole_r , " at ", hole_dist_side, hole_dist_top); cylinder(r=hole_r, h=thickness*2); echo("Putting a hole with radius: ", hole_r , " at ", hole_dist_side, height - rail_clearance - thickness*2 - 16.5/2; // 16.5 is the decade counter Bergman's 10-step sequencer (AKA Baby10 Outputs synchronized pitch and FM modulation, hard sync, and pulse wave width, and PWM level. Unseen Servant Primary source: ## Kassutronics Precision ADSR build notes The build is pretty straightforward except for mechanical assembly, and one with an eye towards doing it all in one module with lots of analog drum voices; based heavily on Moritz Klein's work, but will need painting. Could be glued on with CA or hot glue, if the PCB is used.
