Song Production: The Basics

This paragraph deals extensively with all aspects of CS2x song production and makes no attempt to filter out

any “specialist knowledge”. This doesn’t mean though that it is necessary to fully explore each aspect in

order to create songs with the CS2x.

Our earlier chapter “Song Production – An Easy Start” made that obvious. Everything you need to know for

a quick start into multi-timbral applications with the CS2x can be found there in compressed form.

However, should you wish to take a more informative but less comfortable route through the following, often

complex material, we recommend plenty of patience. Please take the time to work through each of the suc-

cessive subjects and try out as many of the accompanying examples as possible. Your song productions are

bound to benefit from it.

What is “XG”?

If you are planning to use the CS2x to play back or record sequencer songs, you should already have heard

something about “XG” and be familiar with its most important properties.

The XG Standard is a format developed by YAMAHA and is used to control tone generators. Although XG is

based on General MIDI (GM), it represents many qualitative and quantitative improvements over this stan-

dard. XG supports greater musical expression: the total number of sounds available in GM is drastically

increased in XG. Furthermore, individual sound settings and real-time control of a multitude of parameters

are now possible. Finally, compatibility between different XG models is guaranteed despite differences in

tone processing.

The XG voices are organized into banks which, with the exception of the GM compatible Bank 0, are not fully

allocated. This may at first seem confusing. A quick look at the supplied XG-Voice List however clears things

up: Bank 1 and all following Banks (with the exception of the SFX-Bank) are variations of the foundation

sound. The different sound characteristics can be found from each bank’s column label (e.g. Stereo, Single,

Slow, Fast Decay etc.). This should greatly simplify the search for a particular sound. Please also refer to

table “XG Voices” in the section “Decisions, decisions…”.

Another property of XG is that the Parts’ (i.e. the MIDI channels’) sound and effect settings are integrated as

Controller and System Exclusive data in each sequencer track, rather than stored in the keyboard itself. This

has both advantages and disadvantages.

One advantage is that songs recorded in the XG standard are always played back correctly, regardless of

which XG model the song is being played back on. Total compatibility between a whole product range is

guaranteed by the standardization of all sound settings down to the smallest detail. Time consuming sound

bank transferrals and the accompanying risk of data loss are thereby avoided.

EXAMPLE:

You have recorded the foundations of a song on your CS2x and now wish to pass on this embryonic composition to

another musician, so that he can develop your ideas or add further tracks. Without a common standard your partner

would have to spend a lot of time in preparation – he would have to assign MIDI channels, find correct sounds and trans-

pose octaves correctly, or even modify the drum map. Not so with XG: your partner can use your files with a MU-50

sound module, the QS-300 synthesizer, the DB50XG sound card or any other XG model without modification. He will

hear the song exactly as you recorded it. This greatly aids and encourages co-operation between musicians.
