I built an analog synth from 1979!
David Hilowitz Music・8 minutes read
The text discusses the assembly process of a rare synthesizer kit from 1979, highlighting challenges in assembling the main circuit board without instructions or labeled wires. By experimenting with wire combinations, specific functions such as keyboard, volume control, and vibrato are identified, with the synthesizer eventually producing unique sounds with features like a volume slider acting as a filter.
Insights
- The 1979 synthesizer kit, despite its rarity, presents a challenge due to missing parts and lack of instructions, requiring trial and error in wiring connections on the circuit board for sound production.
- The synthesizer's unique construction involves a keyboard made of fixed resistors for pitch variation, with tuning to a 440 Hertz key, and innovative features like using a volume slider as a filter, enhancing the dry sounds produced by the device.
