Synthrotek Analog VCO 1V/O Tracking Calibration Instructions - DIY MODULAR SYNTH!

There are two trimmers for calibrating 1V/octave pitch tracking. V/OCT & HF The process can be broken down into a a few steps per each trimmer for simplicity. V/OCT Trim 1. On the front of the panel (using coarse and fine controls), tune to a fundamental frequency that can be easily verified several octaves up (e.g. 20Hz, 50Hz or 100 Hz) 2. Apply 1V to V/oct input 3. Adjust trimmer to 2x the initial frequency. 4. Apply 0V to V/oct input 5. Readjust tuning on the front of the panel to match initial frequency. 6. Repeat steps 1-5 until 1V is 2x the original frequency. 7. Repeat steps 1-6 until the first 6-8 octaves are calibrated, or you’re satisfied with the range that is calibrated. HF Trim This should only affect tracking at high frequencies where there can be a slight drop in current within the exponential generator inside of the 3340 IC. 1. Calibrate the V/oct trimmer first 2. On the front of the panel (using coarse and fine controls), tune to a very high frequency (e.g. 2kHz, 4kHz, 8kHz) 3. Apply 1V to V/oct input 4. adjust trimmer to fine tune the high frequency tracking 5. Apply 0V to V/oct input 6. Retune the fundamental you started with on the front panel controls. 7. Repeat 3-6 until that octave is calibrated 8. Repeat 3-7 for each successive Voltage/octave, and/or until satisfied.
