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.

Currently, there are 19 modules online that can be put together in different ways and patched. However the system is growing and changing as we are currently working on it.


Here you find the “stl” files for the Paper Bit Frames:


All flters and oscillator use the OpAmp LM358. But for a better sound and a better peap to peak range one can use the rail to rail OpAmp MCP6002-I/P or the TLC 2272. And instead of the LM324 the MCP6004-I/P or the TLC2264.

How to Patch

Paper Bits have two power lines for +5V and the ground and three connectors for the signal, two general busses and one gate bus. Every module several in and outputs. With jumper one can select them to connect the module to the bus or send the signal through without effecting the module or the signal.
All in and output can also be connected via patch cables at the in and output instead of the jumpers.
