The purpose of Rhythm Converter
is to create a CTK-691/WK-3000/WK-3500 accompaniment pattern file
(CKF), which can be loaded and played on the keyboard. Rhythm Converter
does this by combining a Standard Midi File (SMF) containing the musical
data of the accompaniment pattern, with the essential control Parameters
(PRA file) that make the pattern work.
|
|
|
|
|
The Rhythm Converter
process is broadly: |
|
|
|
A .
|
Create the SMF
|
|
B .
|
Open it in Rhythm Converter
|
|
C .
|
Create the 'Parameters' in Rhythm
Converter
|
|
D .
|
Save the final result as a 'CKF'
file
(The finished accompaniment pattern file)
|
|
|
Important Notes
|
:
|
The SMF can
also contain the Parameters for the accompaniment pattern, for example
Tone selection, Volume, Reverb, Chorus, Panning etc. Rhythm Converter
can then extract this data from the SMF to create the Parameters for
the final CKF file. More about this in section 2-1.
|
|
:
|
When you create
your SMF you must follow the guidelines in 2-1 or your final pattern
may not work properly
|
|
:
|
A One Touch Preset
can be created and included in the accompaniment pattern using the
OTP Editor within the Rhythm Converter programe
|
|
|
|
|
|
Create the SMF of the musical
data for your accompaniment pattern in your chosen Sequencer Programe.
The following is the structure required for the SMF.
This must be adhered to or
the final accompaniment pattern will not work properly.
|
|
|
|
|
The SMF must contain
the following pattern 'Elements': |
|
|
|
|
Intro 1 |
|
Intro 2
|
|
Variation 1
|
|
Variation 2
|
|
Fill 1 (from Variation 1 to
Variation 1)
|
|
Fill 2 (from Variation 1 to
Variation 2)
|
|
Fill 3 (from Variation 2 to
Variation 2)
|
|
Fill 4 (from Variation 2 to
Variation 1)
|
|
Ending 1
|
|
Ending 2
|
|
|
Important Notes
|
:
|
These distinct
parts of the Accompaniment Pattern are referred to in Rhythm Converter
as 'Elements'
|
|
:
|
You must set
markers to define the different Elements of the pattern. The markers
must be set at the "Split Points" between the Elements. (The measure
number at the start of each Element). This can be done in one of two ways
as detailed in 2-2 'How To Use Markers'
|
|
:
|
Fill Ins must
be one Bar in length and there must be no empty bars between each Element
in your SMF
|
|
:
|
All of the patterns
Elements must be programed in the key of C. The Intro and Ending can
be based on a chord progression, which should be in the key of C, or
written so that it resolves to the root of C. The Variations and Fills
must be written in the key of C Major.
|
|
|
|
|
In the SMF the following
tracks must be on the specified Midi Channels: |
|
|
|
|
Drums
|
Channel 10
|
|
|
Bass
|
Channel 11
|
|
|
Chord 1
|
Channel 12
|
|
|
Chord 2
|
Channel 13
|
|
|
Chord 3
|
Channel 14
|
|
|
|
Note |
: |
It is not necessary
to fill every part, for example you could just use
Drums, Bass and Chord 1 to create a simple pattern. The important
point is that the parts must be on the above Midi Channels or the pattern
will not work properly.
|
|
|
|
|
The Following Midi Data
can be recorded: |
|
|
|
|
Note On / Off
Modulation
Pitch Bend (Range = 2 Semitones)
|
|
|
|
|
The SMF must contain
the following parameters for each Element at the top of each track: |
|
|
|
|
Programe Change
Bank select (Controller 0)
Volume (Controller 7)
Pan (Controller 10)
Reverb Send (Controller 91)
Chorus send (Controller 93)
|
|
|
Important Notes
|
:
|
If these parameters
are not included in the SMF you can set them in the Rhythm Converter
programe. If they are set in the SMF, Rhythm Converter will extract them
and display them in the 'Element Editor'. See 4-1 'Using the Element Editor'.
|
|
:
|
These are referred
to in Rhythm Converter as 'Parameters'. This is the data stored in the
Parameter file (PRA)
|
|
|
|
|
|
There are 2 ways to mark the
split points between each of the ten Elements within the SMF:
|
|
|
|
A .
|
Insert Markers in the SMF to
define the Split Points
|
|
B .
|
Set the Split Points within
the Rhythm Converter programe
|
|
|
|
A . Setting Markers in your Sequencer
Programe
Depending on the sequencer Programe you use to create your SMF,
insert a text event (Marker) in the SMF at the start point of each element
(one for each of the ten elements) and a final Marker to show the end
point of the data (ie: the top of the measure after Ending 2).
The positions of these Markers are referred to in Rhythm Converter
as "Split Points", literally marking the points where Rhythm Converter
should split the sequencer tracks into the different accompaniment pattern
Elements. As there are Ten pattern Elements, your SMF should have totally
Eleven Markers, including the end Marker.
|
|
|
|
B. Setting the Split Points within
the Rhythm Converter Programe
To set the Split Points in Rhythm Converter simply enter the
start Bar and Bar Length of each pattern Element as in this example:
|
|
|
Important Notes
|
:
|
All Fill-ins
must be one bar in length. Fill-ins exceeding one bar cannot be guaranteed
to operate correctly.
|
|
:
|
There must not
be any empty bars between any of the Elements within the SMF.
