Chipwave[See also: My (big) project on Chiptune synthesis. Please email me for the accompanying Cycling '74 MaxMSP chiptune synthesiser patches]Here is a pure data patch that will allow you to generate "chiptune" sounds relatively easily using pd. 
Download here: chipwave.pd you will also need adsr.pd It is based on a system of CONTROL TABLES. One control table is responsible for selecting a waveform for each of the 4 channels of sound by reading a value from a table every 25 miliseconds. The pitch of the waveform can be altered by reading values from a table too. This method is like a mini-sequencer, one that gets triggered every time a MIDI note is played. This behaviour is almost identical to the idea of "instruments" in "tracker" software. A very complex sequence of sound texture changes can be programmed very easily, to create sounds similar to Nintendo Gameboy, NES, Commodore C64 and Atari. Using these mini sequences, or instruments, you can create waveforms that look like this, and sound like this. [mp3 example here]

*** Please note that the default patch is set up for lower amplitude on channel 1 compared to other channels. *** |
