Excerpt
from “SOS Hardware and Software Connections” Music Row Magazine
In the last issue I covered the hardware needed to complete
your home studio the computer and peripherals. I didn't say anything about how
to connect them. Before we gel into the software aspect of the home studio, I
want to briefly touch on this subject.
When you purchase your computer some software will already be
installed. Most systems these days come with Windows XP Windows. Don't be
alarmed if you've never set up a system before, it's easy. If you look on the
back of the computer you'll see several connectors. Each is different. The
printer can only plug into the printer port and the mouse into the serial or
mouse PS2 port. The video and sound cards have their own connectors as well.
The only connector that's duplicated is the game port. This is a 15 pin female
socket. Most sound cards and super 1/0 cards have game ports. One of these must
be disabled. This can be done through software on some cards or by setting a
jumper on others. If you don't disable one of the ports, things won't work.
Every card in the computer comes with installation instructions. Read Them! It
will only take a few minutes, and you can save yourself hours of time and
aggravation by getting familiar with each card before you install it.
You'll need to know which interrupt and port address to
use. This may sound like gibberish now, but it will make sense after you've
read the instructions. It will be up to you to install the midi card. Choose an
empty slot. Be careful when pushing down on the card. It should slide into the
slot without a lot of pressure. If it doesn't, check to see if a wire has
slipped under the edge connector. This has happened to me on several occasions.
If you put too much pressure on the card you can break a foil trace on the
mother board so press gently. The card should go in easily.
When you get your sequencing software read the instructions
before you do anything else. There may be an addendum on the floppy disk as
well. Look on the disk directory for a Read-me or Text file.
Before I tell you how to install your software, let me
explain in more detail exactly what a sequencing program is and how it records
your compositions.
I'm sure that most of you have recorded on a tape recorder.
To record a song on a tape recorder, you'd take a microphone and play an
instrument into it. The sound is converted into electrical impulses and stored
on magnetic tape. The quality of this tape is very important. Higher quality
tape has less inherent noise.
You've probably seen Dolby or DBX on the better recorders.
These are types of noise reduction processes that lower the level of ''hiss''
that's present on all tapes. This type of recording is an analog process. What
you hear when you play the recording back is the sound your original recording.
Sequencing programs work in an entirely different manner.
First they are digital. This means they don't need any noise reduction. Only a
series of ones and zeros are recorded on the hard drive. Actually, a computer
can only read ones and zeros. That's it. Every program, data sequence, or
whatever, is just a series of ones and zeros to the computer. There’s no need
for noise reduction here because….there’s no noise!
Secondly, the sequencing program doesn't record the music
at all. What a sequencer records is the midi performance data. Every time you
strike a key on the midi keyboard the computer records it. It knows how hard
you struck the key, what note it was, what instrument it was, and if it had any
tremolo or pitch bend attached to it. How long you held the key down is also
recorded.
There is a case where the computer does record the actual sounds.
when you sample a song or instrument you are
converting the musical sounds to a series of ones and zeros and storing them on
the hard drive. Sampling records the sounds not the midi performance.
When you play a sequence back, you can choose which instrument
you want to hear. You may have chosen a piano when you originally recorded your
song. But you can easily change the piano to any of over a hundred other
instruments when you play it back.
