With the audio stack latency at somewhere around 10 ms for optimized drivers, you’ve got about 10-20 ms lag between you pressing a key and hearing the sound – assuming there’s no additional DSPs and buffers along the way.Īdding 10 ms doesn’t sound much, but when you’re playing the virtual instrument, the PC keyboard makes you play slower than the MIDI keyboard because you’re instinctively waiting for the notes to come out. The latency for the PC keyboard is ideally about 8 ms, whereas a standard hardware MIDI keyboard goes down to about 0.3 ms per byte, and a MIDI USB interface can be set to a refresh time of 1 ms at the fastest.

It’s common for music software to provide a virtual keyboard that maps to the letters on the PC USB keyboard. The brain locks on to the stronger stimulus. Posted in Peripherals Hacks Tagged arduino, carriage return, clicky keyboard, keyboard, manual, python, solenoid, typewriter Post navigation

Weird hex, but OK.Ĭan’t get enough typewriter action? We understand check out this typewriter-cum-USB keyboard, the tweeting typewriter, or this manual typewriter that pulls some strings. The last solenoid rings a bell when it’s time to return the carriage, which is done with a combination wrench as a handle.

Version two, shown in the video below, ups the simulation with a motor that moves the solenoid rack one step with each keypress, to simulate the moving carriage of a typewriter. Whatever the cause, the effect is a realistic variability in the sounds, just like a real typewriter. Each one sounds different somehow, perhaps due to its position on the board, or maybe due to differences in mounting methods. The coils are connected to an Arduino through a relay board a Python program running on his PC reads every keypress and tells the Arduino which solenoid to fire. The first version had the core functionality, with a line of six solenoids mounted to a strip of wood. Unwilling to miss out on the feel of real typing, whipped up this solenoid-powered typewriter simulator. Oh, and the bell - who doesn’t love the bell? The sounds that a typewriter makes, from the deep clunk of hitting the spacebar to the staccato of keys striking paper to the ratchety kerchunk of returning the carriage, are a delight compared to the sterile, soulless clicks of even the noisiest computer keyboard. No matter how clicky your keyboard is, nothing compares to the sensory experience of using a typewriter.
