MIDI Environment Variable

The MIDI environment variable specifies the MIDI file format used and where the MIDI data is sent to. The MIDI data can be sent to FM chips or audio hardware MIDI port. Generally, there are three MIDI file formats available in the market, General MIDI, Extended MIDI and Basic MIDI. You can type “SET” at the DOS prompt and see the following line for the setting of the BLASTER environment variable:

MIDI=SYNTH:<1/2> MAP:<G/E/B>

Where:

 

 

SYNTH:

1

Specifies internal synthesizer (default)

 

2

Specifies audio hardware MIDI port

MAP: G Specifies General MIDI file format

ESpecifies Extended MIDI file format (default) B Specifies Basic MIDI file format

Maximum Recording Rates for the Audio Hardware

The sampling rate used for recording is largely influenced by your computer’s main processor. To obtain 16-bit digital audio using Windows, the following maximum recording rates are suggested.

SYSTEM

RECORDING RATE

386 and above

Stereo - 44KHz

 

Mono - 44KHz

 

 

386 SX and below

Stereo - 22KHz

 

Mono - 44KHz

 

 

To obtain optimal performance, try configuring the audio hardware to use a high DMA (Direct Memory Access) channel under Windows. Refer to your audio hardware Getting Started Manual for more information on setting up the sound card to use a high DMA channel.
