General information

• 120 Years of Electronic Music  
• Add Realism to Your Synthesized Sequences - article first appeared in the November 1997 issue of Recording magazine  
• Analog Music Zone - circuits, software, FAQs  
• Electronic Music Interfaces  
• Guitar Amplifiers - Guitar amplification is a specialised field, where much commonly understood theory does not apply, and little theory is published. Technically speaking, a guitar amplifier has a specific type of non-linear gain at its signal extremes, and a specialised type of limited frequency response. This article collection has lots of information on guitar amplifiers.  
• Guitar Amplifier Basics - This document tells about the technology of guitar amplifiers.  
• Harmony Central Internet Resource for Musicians - attempt to bring together music related items  
• Hyperreal Music Archive  
• Music & Audio Connection - software, resources, audio-related companies  
• Music Machines at Hyperreal - home of musical electronica  
• The Musician's Ultimate CyberWorld Destination  
• The Music Yellow Pages - index of manufacturers, wholesalers, distributors and nationwide retailers for the music, pro audio, entertainment and lighting industries

Instruments

• A Paradoxical Sound Syntetizer - the main property of paradoxical sounds is that their frequency do not change when you go an octave higher   
• Analog Music Synthesizers - Analog synthesizers have been around for a long time, they seem to be back in vogue these days. Musical sounds can be fun to make using all kinds of technologies, analog, digital and acoustic. Analog synths offer some nice capabilities such as the ability to easily modify many sound parameters while the synth is being played. The one knob per function user interface costs a bit more to make but it is vastly more interesting to use compared to the 4 button/LCD interfaces found on so many modern synthesizers. This page gives some example circuits on analogue syntetizers.

MIDI ( The Musical Instrument Digital Interface )

General

• Making your own MIDI Cables  
• MIDI channels, voices, timbres and Modes  
• MIDI Manufacturers Association - The MMA was formed in 1984 as a "trust" to maintain the MIDI specification as an open standard. The MMA provides forums for discussion of proposals aimed at improving and standardizing the capabilities and marketability of MIDI-related products, and provides a process for adoption and subsequent publication of any enhancements or clarifications resulting from these activities.  
• Musical Instrument Digital Interface (MIDI) - overview  
• Midi Cable (both ends) - This is standard wiring pinouts for Din connectors for MIDI use.  
• Midi Cables Pinouts  
• MIDI Manufacturers Association - source for information on MIDI (Musical Instrument Digital Interface) technology
• Standard MIDI File (SMF) Format  
• The Midi Archive - MIDI and other electronic music stuff, patches, software, songs, documents, links  
• Standard MIDI Files 1.0 - This document outlines the specification for MIDI Files. The purpose of MIDI Files is to provide a way of interchanging time-stamped MIDI data between different programs on the same or different computers.  

MIDI circuits

• Creating Custom MIDI Sensors   
• DIY MIDI Controllers using PIC Microcontrollers and Basic Stamps - By combining a PIC microcontroller or Basic Stamp II with a few passive components it is not difficult to construct your own knob box, trigger box, or other MIDI input device. A knowledge of electronics may be required for interfacing to some sensors. Both the Stamp and PIC provide an economical (under US$100) entry point into the world of alternative MIDI controllers.  
• Low cost analog to MIDI convertor - 8 channel converter  
• Low-Cost MIDI-Knobbox - text in German and English  
• MAnMIDI - Multiple Analog to MIDI - MAnMIDI is a chip for converting multiple voltage sources into midi controller output, for connection to synthesisers or computers with midi inputs. Low power consumption, 6 mA @ 3-6 V, and low component count allow you to build very compact and portable applications with ease. Readymade MAnMIDI chips in 18 pin DIP packaging are available at $30 each.  
• MIDI controlled switches - can drive up to 128 individual relais, solenoids, motors, etc. with a MIDI note-on and note-off messages  
• Midi Passthrough Circuit - circuit with one MIDI input and on or more outputs   
• Music Machines: do-it-yourself  
• ReTurn MIDI Controller system - Programmable DIY MIDI controller with many functions (eg SysEx, NRPN etc) and its own Windows setup editor. Not quite free though, preprogrammed MCU with firmware can only be purchased from author.
