Paper-Bits Paper Bits is a small, modular synthesiser system voltage controlled, created by Wolfgang Spahn. The start was at the Art Science BLR and the Indian Sonic Research Organization with support of Goethe-Institut Max Mueller Bhavan in 2016. Its further elaboration was done with help of Angelo Thomaz, Ioana Vreme Moser and many many more. Its simple design, accessible interface as well low price, offer a powerful sound tool dedicated to learning, experimenting, and playing.

PB101 Sync VCO The Sync VCO is actually a pair of oscillators, a normal voltage controled oscillator and an other oscillator that syncronice the first one. It comes with a triangle and a square wave output. In changing the capacitores one can change the range for the oscillators. The value should be between 10 and 50nF.

PB105 Saw Sync There is a new version of this oscillator. Please use the PB101 Sync VCO instead. That is an other version of the PB101 Sync VCO with a switch for shaping the waves. In square wave mode one can change to a super short duty cycle and in triagle mode one can switch the wave form from triangle to ramp. The board itself has some smal mistakes compared to the

PB109 VCO II This is the main voltage controlled oscillator due to its really beautiful shaped sine wave - it is stable and with the same peak to peak over all frequencies. One can switch between square, triangle and sine wave. In the square/triangle mode one can change with a potentiometer from triangle to sawtooth wave or change the duty cycle of the square wave. In sine wave mode one can shape the sine wave to an interesting

PB201 Step Sequencer There is a new version of the sequencer use the PB206 Sequence (Total) Recall instead That is the 8 step sequencer for the Paper Bits. One can change steps, speed and the value of the CV output. To change to output for each step one select a value with the poti and in pressing the button for the step it will be asigned to it. The speed can be voltage controlled, too.

PB202 MIDI to CV That MIDI and MIDI over USB board give four 0 to 5V output signals, CV1, CH2, CV3 and CV4. CV1 and CV2 are filtered. The CCNumber are 1, 2, 3 and 4 on chanel 1. That can be easily modified in the code. The board also outputs a trigger signal on an clock impulse. The poti is used as a clock divider.

PB204 Sync Sequencer There is a new version of the sequencer use the PB206 Sequence (Total) Recall instead That is the latest 8 step sequencer for the Paper Bits. One can change steps, speed and the value of two independent CV output. Because it has an external trigger input one can easily synchronize them. It's evan possible to build an 16, 24 or 32 step sequencer out of two, three or more of them.

PB206 Sequence (Total) Recall That is again the latest 8 step sequencer for the Paper Bits. This version of the sequencer can store the sequences in the chip's EEPROM and one could call them again after rebooting the device. One can also change steps, speed and the value of two independent CV output. As it has an external trigger input one can easily synchronize it with an other sequencer.

PB701 Electric Intonarumori The core of that noise board is the digital delay chip PT2399. It has some OpAmps build in to filter the sound and do the echo. In this application everything that helps to get rid of the noise of the chip itself was avoided, that leads into a self sustainable noise source.
