- *NOTE: The B° or B halfdiminished may be obtained more simply by
- transposing ten semitones then sharpening the root.

-
- The purpose of this chart is to assist the user in choosing the most
- appropriate transposition within their favourite MIDI sequencing package
- for a given sequence of pre-generated MIDI style data. Each generated set
- of style data uses notes bound to the key of C MAJOR and are in fact based
- around the CMAJOR 7 chord. For compositional purposes then it is possible
- to copy and transpose these styles and reproduce them in any acceptable
- combination in order to obtain an instrumental backing sequence.
-
- Initially the style data should be edited to extract the drum data from
- MIDI channel 10 and where applicable the percussion data from MIDI channel
- 11 before transposing . The remaining four style tracks on MIDI channels
- 12-15 may then transposed within your MIDI package and then merged back
- with the drum and percussion data during production of the composition.
- After cutting, copying, transposing, merging and pasting the MIDI style
- data within your MIDI package it soon becomes a simple matter to build up a
- more complete structure of several bars of styles into a full-blown
- composition. Please note depending on how your MIDI hardware is configured
- you may need to set up a patch to correspond to the correct MIDI channels
- and in some cases more than one set of drum/percussion on seperate MIDI
- channels may be unacceptable in which case it should be a simple matter to
- set the percussion to the same channel as the the drums within your MIDI
- sequencing package.
-
- Within the i3 transposition chart S.T. denotes a semitone, a flat is
- represented by the symbol b, a sharp by the symbol # and enharmonic tones
- are enclosed within parentheses. The chart indicates the necessary
- alterations required for a given style in order to achieve the desired
- transposition. Since each style is based around CMAJ7 then to obtain for
- example the fourth degree (i.e F MAJ7) of the harmonized chord scale we can
- see from the chart requires a transposition of 5 semitones with no
- alterations. In order to transpose a style to the fifth degree (i.e. G7)
- would require a transposition of 7 semitones and all 7ths would be required
- to be lowered a semitone (indicated by the b7 in the chart). Similarly for
- the second degree (i.e. Dmin7) a transposition of 2 semitones on the style
- would be accompanied by a flattening of all the 3rds and 7ths indicated by
- b3,b7 in the chart.
