Sequencer Programmer In keeping with the vintage theme, this is a proposal for a sequencer/programmer.
The basic structure of this has been tested. A four step sequencer has been prototyped. Push any button, and that relay latches in, and the others all release - basically your one-of-many latching switch bank. This can easilly be constructed using 12 volt relays, 1N4001 (or better) power diodes and 12 volt lamps. All trigger and set inputs are +12 volts and should be of sufficient current to close a relay. Do not expect this to function from the gate outputs of a solid state synthesizer.
A note to readers: this circuitry is intended for the more advanced builder. Because high voltages are used, a shock hazard exists. We do NOT recommend that the novice DIY musician try to construct this synthesizer. Some experience with tube electronics is highly recommended.
