MIDI is a term which usually refers to a hardware MIDI interface connected to a MIDI keyboard or musical synthesiser. This involves the expense of both the interface and the keyboard.
The ESP MIDI Synthesiser is a General MIDI Synthesiser that provides, in software, the capability to play MIDI based music on any Acorn RiscOS machine.
It can be used with the accompanying player to playback MIDI files which are widely available. In addition, it will playback from any RiscOS music program that supports MIDI. It also provides MIDI playback from the PC Card for both DOS and Windows applications.

The Synthesiser comes with a full General MIDI set of instruments which provides 128 melodic and 50 percussion instruments. This covers a wide range of orchestral sounds as well as sound effects. Additional instruments are available from ESP as well as an Instrument editor to allow you to create new instruments from a variety of different sources.

In order to support the wide range of Acorn machines the Synthesiser can provide different levels of quality and different numbers of notes at one time (polyphony). The higher the quality the lower the note polyphony. This means that you can configure your Synthesiser to suit your requirements of performance versus quality. An application is provided that enables you to select the instruments that are loaded. You can also set the maximum amount of memory for the Synthesiser to use to store instruments, after which time instruments are loaded from disc as and when they are needed.
