| Six distinct square wave pitches generated by the six Schmitt Triggers of a 40106 integrated circuit. Four of the feedback oscillators are mixed to the output with diodes, maintaing their respective pitches. The remaining two oscillators are mixed to the output with resistors. At higher frequencies, the two oscillators mixed with resistors have a slight modulating effect on the entire mixed output. As this synthesizer is one of my earliest builds, I improvised a very crude filtration device with a 2.2uf electrolytic capacitor and the linear taper potentiometer seen on one side. Despite its simplicity, this synth continues to surprise as it ages. The board is housed in an old camera case. I have come to regret removing the case's original strap, realizing that it could probably be used strikingly in a variety of performance contexts. Rusty, stark, and conjuring visions of juvenile bike rides and sea salt, it seems to encourage its own portability. |
40106 Synthesizer Sample I by Young Rites
The wet sounds of high frequency oscillation at the upward limits, accompanied by a "wupping" WSG.
40106 Synthesizer Sample II by Young Rites
Four constant square waves in unison. Imprecise chord progressions are enabled by changing the frequency of one oscillator at a time, slowly building a new chord around each change. This takes practice, but the difficulties of precisely harmonizing can also generate interesting discoveries. After transferring this recording from four track cassette to digital format, I duplicated the .wav file and slightly adjusted the duplicate's pitch to improve on flat transitions.
