Hello all, I am currently constructing a DIY 61 key electromechanical keyboard based off the Fender Rhodes. During my testing phase, I have wound a pickup myself with which I am going to base the 60 other pickups off of. Currently testing the one pickup, I simply run this into my Roland/Edirol UA-25 USB interface to send the audio into Cubase.
So now you know my setup, my question is as follows regarding electronics theory. If I have 61 pickups wired in series, will the microphone input of the USB interface provide sufficient power for all 61 pickups, or will I need to introduce an additional power source into the circuit in order to make them work appropriately?
Thank you
Ps. Below I have attatched an image of the construction I am emulating.

Power? They are totally passive pickups, just like pickups in a guitar. They use no power.
Strictly speaker I do not believe they are in series. Look at your photo, in that you have them wired three at a time in parallel, then those groups are in series. her is a link to a brief description:
Steve's Corner - Pickup Maintenance & Replacement
Then feed the resulting signal to a preamp, et voila, "piano".
if you google "Rhodes pickup wiring" or "Rhodes pickup adjustment", you should find all manner of tutorials on the subject. Setting the pickups is easily done by ear - not sure else how we might do it than by ear. In/out for loudness, and up/down for overtones.
I have a whole Rhodes service manual, but it is too large to post on the forum here. it may also be online easy to find, I didn't look, but if you want it, PM me your email address.

Thank you Enzo for your thorough explanation and for pointing me in the right direction. This is very helpful information.
