http://www.digifreq.com/digifreq/ There may be times when you want to convert one type of MIDI
controller into another. For example, you may want to convert some
prerecorded MIDI modulation (#1) messages to MIDI volume (#7)
messages for a little sound level experimentation.
Most sequencers provide this functionality, but it is often
difficult to find. Two such sequencers are Cakewalk's Sonar and
Steinberg's Cubase. Taking from the earlier example, here's how to
achieve the transformation in either application:
Cakewalk's Sonar:
1) Select your MIDI data.
2) Choose Edit > Interpolate.
3) Click the None button.
4) Activate the Control option.
5) Enter the same value for the Number Min and Number Max
parameters. This is the number of the existing (or source) MIDI
controller. In the case of our example, this would be 1.
6) Click OK.
7) In the next dialog box, enter the same value for the Number Min
and Number Max parameters again. This time enter the number of the
destination MIDI controller. In the case of our example, this would
be 7.
8) Click OK.
Steinberg's Cubase:
1) Select your MIDI data.
2) Choose Functions > Logical Editor.
3) Click the Init button.
4) Under the Filter section, choose Equal and Control Change in the
two Event Type drop-down lists, respectively.
5) Under the Filter section, set the Value 1 drop-down list to
Equal.
6) Under the Filter section, enter the value for the existing (or
source) MIDI controller for the Value 1 parameter. In the case of
our example, this would be 1.
7) Under the Processing section, leave the first Event Type drop-
down list set to Keep.
8) Under the Processing section, set the Value 1 drop-down list to
Fix.
9) Under the Processing section, enter the value of the destination
MIDI controller. In the case of your example, this would be 7.
10) Under the Functions section, set the first drop-down list to
Transform and click the Do It button.
Using either sequencing application, the MIDI controllers in your
data are automatically converted. By experimenting with Sonar's
Interpolation and Cubase's Logical Edit, you'll be amazed at the
number of ways you can manipulate your MIDI data.
