A significant correction has been made to the schematic after successfully operating a second board. The manual sweep circuit is now designed to return to ground instead of Vref. Additionally, the feedback limiting resistor has been increased from 100K to 270K. This section of the circuit may require further experimentation since the capacitor in series with that resistor influences the bass level in the feedback signal, which subsequently affects the onset point.

The schematic revision introduces critical changes aimed at enhancing the circuit's performance. The alteration of the manual sweep circuit's return path from Vref to ground is essential for ensuring proper signal integrity and stability during operation. This modification is expected to improve the overall functionality of the circuit by minimizing noise and enhancing the response time.

The adjustment of the feedback limiting resistor from 100K to 270K serves to fine-tune the feedback loop's gain characteristics. A higher resistance value results in a reduced feedback signal, which can help prevent distortion and improve linearity in the circuit's output. This change is particularly relevant in applications where signal fidelity is paramount.

Furthermore, the inclusion of a capacitor in series with the feedback resistor plays a crucial role in shaping the frequency response of the circuit. The value of this capacitor directly influences the cutoff frequency, thereby determining the amount of bass present in the feedback signal. By experimenting with different capacitor values, users can optimize the circuit's performance to achieve the desired tonal characteristics, particularly in audio applications where bass response is critical.

Overall, these modifications not only enhance the circuit's operational capabilities but also provide opportunities for further experimentation, allowing for tailored adjustments to meet specific application requirements. The careful consideration of component values and configurations will lead to improved performance and adaptability of the circuit in various electronic systems.I have made a major correction to the schematic as a result of getting a second board going. The manual sweep circuit should return to ground not vref. I also increased the feedback limiting resistor from 100K to 270K. This area of the circuit might bear some experimentation as the cap in series with that resistor determines the amount of bass in the feedback signal which affects the onset point. 🔗 External reference
