Mutually Crafted Happiness: How MCH2022 Happened 16 Comments IвЂ™ve often likened the concept of how a (basic) CPU works to that of a very fast player piano each clock cycle stepping a counter which updates the вЂњaddressвЂќ for the memory, and other clocks in sync with the base clock setting or reseting status lines to transfer data in and out of memory, into registers, or telling the ALU what to do with a register or two (or the contents of memory) вЂ“ with the memory being the really long вЂњpiano rollвЂќ of вЂњnotesвЂќ (each вЂњnoteвЂќ being an operand and some data вЂ“ again, basic design here вЂ“ thereвЂ™s a ton of ways to represent and build a CPU of course). It also seems like the system had the capability to вЂњloopвЂќ (return to beginning of roll and continue to play).ДЄll in all вЂ“ player pianos are fascinating machines of a bygone era. The article covers everything about this system, which was really a digital control system done in pneumatics the author even remarks that it incorporated something akin to a mechanical DAC (!). The purpose of such a piano was to come as close as possible to allow the piano to reproduce the вЂњnuancesвЂќ of the pianist who recorded the roll. The author doesnвЂ™t say what kind of microcomputer he was using, but one could speculate that it was likely some S100 bus 8-bit beast of the era.ДЄ following article (p 122) details the anatomy of a certain kind of player piano, known as a вЂњreproducerвЂќ.

A custom 8-wire serial interface was constructed to minimize the cabling needed to control it.

In the September 1977 issue of Byte magazine, thereвЂ™s an article (p 112) detailing the authorвЂ™s experience with interfacing a player piano with a microcomputer he utilized electromagnetic valves of some arrangement, controlled using peripheral driver ICs (SN75452).

Posted in Musical Hacks Tagged 16:4.5, arduino, lcd, midi, piano, player piano, solenoid Post navigation There are also plans to have this piano output MIDI with a key scanner underneath all the keys. The piano has so far been shown at an interactive art exhibit in Oakland, and hopefully itвЂ™ll make it to one of the Maker Faires next year. The ten different styles of visualization were whipped up in Processing. He found a display with a ratio of 16:4.5 вЂ“ yes, half as tall as 16:9 вЂ“ and turned the front of the piano into a giant display. ThereвЂ™s an astonishing amount of electronic and mechanical work invested in this build, and the finished product shows that.ДЄs if turning an ancient player piano into something that can understand and play MIDI music wasnвЂ™t enough, decided to add a few visuals to the mix. These valves are controlled via a shift register, and the shift registers controlled by an ATMega. The lead pipes were torn out and replaced with 88 separate solenoid valves. Replicating this system for a MIDI device would be impossible, but there are a few companies that make electronic adapters for player pianos.

A series of pipes leading to each key translate these small holes into notes.

Player pianos work via a vacuum, where air is sucked through a few pin points in a piano roll with a bellows. found an old piano in Craigslist for a few hundred dollars, and once it made its way into the workshop the teardown began. This led to one of the best builds weвЂ™ve ever seen: a player piano connected to a computer.

He wondered if anyone had ever tried to convert a player piano into a full MIDI instrument, with a computer tickling the ivories with a few commands. Was always fascinated with pianos, and when he came across a few player piano rolls in an antique shop, a small kernel of a project idea was formed.
