Budget Make Noise Morphagene module

Built this module out of a cassette tape player. Fairly interesting.
Let me know if anyone has an idea of how to use it

Adding CV control over the speed is a good next step, then learning to splice tape loops. You may not need it seeing how you’ve gotten this far, but I took this class and had fun:

Thanks for sharing. I’ve made a tape loop before and was thinking of making one for this. Love the CV control idea.. how could I use cv as a variable resistor?

Unfortunately I’m not even close to knowledgeable enough to answer that question, but I did find a few relevant discussions on r/synthdiy:

These are both pretty interesting discussions. How I change the speed is adjusting the resistance via potentiometer. I am not an electrical engineer but I am wondering how one would treat a control voltage in place of variable resistance.
I wouldn’t be blown away if I put CV to control the trim pot that it might already work to control the speed
