Hi, I the DC interface was working well with a walkman. Following the LFOs signal. Then didnt anymore. I have tried it with the solenoid and it doesnt work but it does work with the motor. Please help. I particularly got this to mess with the speed of a tape machine. block breaker

It sounds like you're having some interesting challenges with your DC interface! Since it worked well with the Walkman initially, it might be worth checking the connections and settings again. If the solenoid isn't responding but the motor is, there could be a compatibility issue or a power requirement mismatch with the solenoid. Have you tried using a multimeter to check the voltage and current output when connected to the solenoid? Also, make sure the LFO signal is still stable and within the required range for both devices. Good luck, and I hope you get it sorted out soon!
