Music synthesizer
The music synthesizer mode offers three operational modes: playing a note, playing one of four pre-stored tunes, or recording a tune for later playback.
In the music synthesizer mode, the circuit is designed to facilitate three distinct functionalities, enhancing user interaction...
8-Way MIDI Drum Pads
Do you have rhythm? Would you like to transfer that rhythm to your computer or hardware sequencer? One of the easiest methods to achieve this is by using MIDI drum pads that can be struck with drumsticks, allowing data to...
Low energy consumption audio signal generator
On occasions when it is necessary to determine if an amplifier is functioning, the most effective tool is an acoustic signal source with a frequency around 1 kHz. The specifications can be considered flexible, as rapid tests typically do not...
MIDI Output with Arduino
This page covers only the details of MIDI communication on the Arduino module. For a more general introduction to MIDI on a microprocessor, see the MIDI notes on Tom's physical computing site. MIDI, the Musical Instrument Digital Interface, is a...
Hammond Commodore MIDI Interface
The schematic circuit board features switches that output -2V when activated and 0V when deactivated. Four 4067 multiplexers combine the 64 switch signals into 4 signals that return to the main PIC board.
The circuit design incorporates a series of switches,...

Digital Audio Selector Circuit
This circuit employs switched emitter followers instead of conventional analog switch CMOS chips, resulting in a more effective reduction of crosstalk between channels. It can manage up to 4 Vms with less than -80 dB crosstalk.
The circuit design utilizes switched...
MIDI tester circuit
Sometimes when experimenting with different soundcards and MIDI interfaces it is useful to see if there is some data going in MIDI interface. This can be easily tested with this adapter, which converts the midi signals to visible light pulses....
