* Resistors marked RLED determine the brightness of the LEDs. A 1k resistor can be used for low mcd LEDs. If you use a superbright LED, this value should be increased, to as much as 33k, dependent on the individual LED. Trial and error is the only way to correctly determine the value. This can be done with a LED, resistor and a power supply of approximately the same voltage as the positive rail of your synth. (i.e. +12V or +15V)

* 33k resistors marked # on the schematic could be replaced with 100k resistors to bring the input impedances up to more modern standards.
