Humming noise Using Sound on Your PC Solving Problems with Sound If the power grounding of your audio components is inadequate, a humming noise may be generated. This may happen if your PC is connected to a hi-fi system. Plug all devices into adjacent power outlets (outlets within 5 cm / 2 inches of each other), or use line filters. The PC hangs while recording Uncompressed digital audio can eventually fill your hard disk. For example, one minute of stereo sound recorded at a resolution of 44 kHz will occupy about 10.5 MB. Before recording, check that there is enough free space on your hard disk. Data compression can reduce the space required. The Windows Sound System ADPCM mode reduces the space required by a factor of at least 2. More advanced algorithms reduce these requirements by a factor of up to 10. The A-law and µ-law hardware compression used by the sound board enables the sampling of sound at a resolution of 16-bits, but it generates the same quantity of data as an 8-bit sample. When recording sound with the Sound Recorder, for example, you can select the compression mode to use. While using a MIDI Many different symptoms, depending on how your MIDI keyboard instrument instrument, there is behaves, can arise from your sequencer program accepting notes from your an echo, or the keyboard and feeding them straight back to the keyboard synthesizer. The result is keyboard notes sound that your keyboard synthesizer tries to play the same note twice, with unpredictable results. There are two possible solutions: "heavy", or you can play only half the notes • Either disable the MIDI Thru capability of your sequencer program (refer to the program's documentation); • Or turn "Local Control Off" at your keyboard instrument. Refer to your keyboard's documentation on how to do this. Alternatively, simply turning on your keyboard before starting your sequencer program may correct the problem. The MIDI keyboard makes no sound If you have been playing your keyboard through a sequencer program on your computer, it is possible that the sequencer has turned "Local Control Off" on your keyboard. This avoids duplication of notes. Refer to your keyboard's documentation for instruction on how to turn Local Control On. English 15
