How to Repair a Poly-61
"Welcome to my documentation of the odyssey repairing some Poly-61s, as i recently bought 3 of them with the intention to get at least 2 of them working perfectly. If you want to repair a Poly-61, i have to warn you - it is quite a lot of work to get it perfectly working again, if it has the full repertoire of usual problems of this synthesizer. First of all, if you don't want to do a full restoration, you should know a bit about the inner workings of the Poly-61. This is where i want to start. So let's have a look at the anatomy of the Korg Poly-61."
Update: unfortunately the link above is gone. I found the following from Really Nice Audio:

"By changing the switches and cleaning the keyboard contacts you can bring a synth back to its former glory."
Continuous Signal Processing: The Fourier Series
via AH regarding the following question:
"Does anyone know the formula for calculating the resulting harmonics the formula for calculating the resulting harmonics of a pulse wave when the pulse width is varied? In other words, a square wave (or pulse wave with 50% duty cycle) has only the odd-numbered harmonics present; how do you determine the harmonics present when the duty cycle is 25%, or any other value?"
Dave Manley followed up with a link to this site.
"This brings us to the last member of the Fourier transform family: the Fourier series. The time domain signal used in the Fourier series is periodic and continuous. Figure 13-10 shows several examples of continuous waveforms that repeat themselves from negative to positive infinity."
Update: also see this Synth Secrets article on Sound on Sound.
