Working With Midi Files
15.1
Introduction
Your XG synth is a superb instrument, designed to offer a large variety of high quality tonal sounds,
supplemented by multiple drum kits, special effects banks and a versatile effects unit. However the real
benefit of the XG format is the expressive control that can be applied to these elements……offering the sort
of performance that was until now only available on machines far beyond the budget of most musicians.
Unfortunately in order to access this wealth of functionality and expression requires the use of complicated
controller and system exclusive commands.
XGedit is designed to hide this complex midi notation from the user and in place provide an intuitive
analogue control interface which it is hoped the musician will find significantly more friendly and thus
productive.
Furthermore, the most important factor considered when producing the editor, was to deliver this
functionality in real-time i.e. when you perform edits, they are applied in real-time (much the same as they
would be from a control wheel or knob on a real synth front panel). Unfortunately standard Windows
controls don't work this way......they only send a value when the control is released. Hence if you move a
slider on a conventional editor it only sends the final position value (and not the values in between). What
this means, is that if you use a conventional editor then you won't get smooth transitional effects and may
have to make do with non optimal settings.
XGedit has been written to overcome these problems, allowing you to hear the transitional changes as the
controls are moved, and thus allowing you to get exactly the effect you're after. Furthermore, if the control
edits are recorded in real-time they can be used as dynamic effects throughout the body of a song
(whooshing filters, wha..wha, LFO ramps)
However all of this functionality is of little use if the user cannot utilise the results in their midi projects.
To this end the following sections describes how best to utilise the editor during the authoring process
15.2
Setting Up Your Midi System
Most Windows Midi port drivers are single client. i.e. only one program on the system can use the port at
any given time. This causes problems when you need an to work in parallel with your sequencer, such that
you can audition edits while the track is playing.
However there are multi client drivers available which allow multiple programs to output to the driver (but
only one program to input) Such a driver is the
Twelve Tone MPU401 driver
(shipped with Cakewalk, but
requiring separate installation from the Windows Control Panel/Drivers applet).
More useful though, is Herman Seibs MULTIMID driver, Hubi LoopBack and Hubi Midi Cable drivers or the
MidiOX - MidiYoke drivers. These can transform any single client drivers into a multi client drivers for BOTH
input and output. Additionally they provide software routing of data from a drivers output to another drivers
input! This allows you to record XGedit output directly into a sequencer while your midi file plays in real-time
(without the need for an external midi cabling)
You can obtain Multimid, LoopBack and MidiOX from the links on my Web Page.
