NOWPLAYING duet

Published on Sep 26, 2014 MILQUETOASTE

"2 Clandestign NOW PLAYINGs form a duet in D major.
NOW PLAYING is an arduino-based quad-tone synth using the tone library and a digitally controlled analog bandpass filter to create generative music based on user-defined musical key, musical mode, length, octave range, and ADSR values for each voice. Units use original lofi speakers amps and other electronics where possible from original circuits."

"Arduino-driven VCOs and a filter make noises via random 8 bit values and bitshifting. Arduino, MAX7221 LED drivers, AD5206 hex digital pot, 3 CD4046 PLL VCOs, OPA opamp, CD4016 quad bilateral switch, and LM386 amp in a reclaimed case covered in vaguely labeled knobbery, right where it counts. USB input for programmability."

Clandestign NOW PLAYING demo

"NOW PLAYING consists of 4 digitally-controlled synth voices, each voice running through a digitally-controlled analog filter, realized through 8 custom vactrols. The whole thing is housed in an attractive console case with vintage wrinkle finish and jewel pilot lamp. Data appears via an LCD display, and there's a speaker, output jack, USB port, and power jack for in/out stuff.

NOW PLAYING generates an endless series of tonal polyphonic notes with expressive envelopes and warm lo-fi sound on the internal speaker; cleaner output is available via the output jack.

Sequence of events:

Apply power to NOW PLAYING. USB works, but a wall outlet sounds better. NOW PLAYING is automatically on in USB mode.

If the PLAY switch is on, NOW PLAYING will calculate and play a preloaded routine, forever.

While the 'play' switch is off, NOW PLAYING will be in menu mode, and the parameters of each of the four voices can be scrolled. Pushing the SELECT button allows parameter changing via the SELECT knob while the button is down:

Musical Mode: 33 musical modes: Major, Minor, Adonai, Algerian, Altered, Augmented, Blues, Chromatic, Arabic, Enigmatic, Half Diminished, Bebop, Harmonic Major, Harmonic Minor, Hirajoshi, Hungarian Gypsy, Hungarian Minor, Insen, Iwato, Locrian, Lydian, Hemitonic, Mixolydian, Neapolitan Major, Neapolitan Minor, Octatonic , Persian, Phrygian, Prometheus, Slendro, Tritone, Ukrano-Dorian, Whole Tone.
