Notes:

(1) 8 ICs are used per 'bank'; 15 sections are sensors (2 diatonic octaves); 1 section is mixer-amplifier;

(2) Current drain ~ 70 mA for 2 'banks'; (3) C values: 10 mfd (lowest f ~ 50 Hz minimum; 0.1 mfd (highest f ~ 1200 Hz maximum) selected; All adjustmetns are very delicate with considerable interaction (except output volume).
