Back surdo (L for low, H for high) R/L: accented note (right/left hand suggested) r/l: quieter note * : trill, generally three very fast notes on repique/caixa, two or three for surdos row_2 = working_increment*1 + row_1; row_4 = row_3 + vertical_space/7; row_3 = working_increment*2 + row_1; working_increment = working_height / 7; // Radius of the hole in the slit, with tolerances // th = thickness * 1; h_wall(h=4, l=right_rib_x); // one more vertical to mount a circuit outside the full dev board (in some cases) Arduino + DAC https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on the Env output, its negative will appear on the mid surdos.
