Hi,
First time posting here.
Forgive my maths and electronics skills, I'm a sound guy.
Trying to work out if I can get the sparkpunk's oscillators to give me an output frequency range of between 300hz and 25khz.
Looking to be able to get mainly the higher frequencies as I'll be using a piezo for a driver.
Ideally I'd like the start and end points on the pitch adjust pots to be a fifth of an octave apart, this would be secondary and not absolutely necessary.
From what I can understand from all the literature/hookup guide I should be able to achieve what I want by changing the values of C3 and C4. What values should I use?
Onto the filter. Is it a band pass filter? Is the pot an attenuator? On the modifications page it talks about changing the center frequency by changing the values of C11, C12, and C13. Is there any way to adjust this with a pot?
Cheers
