MIDI expander with old ISA-BUS soundcard
15. February 2009 - 16:30 — adminAn interesting article about utilizing an old ISA soundcard as a MIDI expander.
Glade - AVR audio library
5. February 2009 - 20:33 — adminGlade is a simple, easy-to-use, 8-bit audio library for the Arduino. It allows you to play sound on the pin 11 of the Arduino board using PWM.
Audio spectrum monitor

MIDI for microcontrollers
10. December 2008 - 1:37 — adminMIDI, or Musical Instrument Digital Interface, is a specification for a communications protocol between digital synthesizers and other digital music devices. It was developed to be as simple and general as possible, to give synthesizer manufacturers as much flexibility as possible, yet still have their instruments talk to each other without communication problems. Here is a simple circuit for MIDI output that works well with Wiring or Arduino, the PIC microcontrollers, the BS-2, and the BASIC ATOM Pro24.
ATMega SID emulator
26. November 2008 - 21:40 — adminThis program tries to emulate the sound chip SID of the famous historical C64 Commodore computer (SID = Sound Interface Device). The SID emulator includes all registers of the original SID, only minor functions are not implemented yet.
