Frequently asked questions.

How do I specify a chord change at the third beat?
In the song window, precede the chord with two comma's. One for each beat delay. In the sequencer window, precede the chord with the beatnumber e.g. 3:Dm. Or drag the beatnumber (listed in brown beneath the barnumber) to the desired value before you specify the chord.

Why do I get an empty MIDI file after recording in the voices window?
After pressing the record button you must start the accompaniment by playing a chord. Any melody that you play before the accompaniment starts is not recorded.

Why does the sequencer stops playing and recording after bar 12 while there are chords defined until bar 32?
In the sequencer window playing or recording will stop after the last part in the sequence is played once. This last part is supposed to be the ending. If you don't have an ending part in your sequence then add a marker with the stop option selected after the last bar that should be played.

Why is there a delay between the time I press a melody key and the time I actually hear the sound?
This problem may occur when you are using a software synthesizer like the Roland VSC. This problem is called latency. Some (on board) soundcards also make use of software synthesis. A Soundblaster soundcard (any type) will give acceptable sound quality without latency. Yamaha provides XG soundcards that will give excellent results but are much more expensive. 

Why do I hear a delay when I switch variations?
This problem should not occur with the include styles and most Yamaha factory styles. It may occur with a lot of converted styles. These styles often contain bank and patch changes and controller settings at the start of each variation. Some (older) synths need a lot of time to process this changes. You can use the style window to remove these redundant events.

Why do I get the message "Unable to open file" whenever I try to open a style file?
This problem occurs in the Chinese version of Windows 98 and in the Korean version of Windows ME. There haven't been reports of this problem occurring in Windows XP in any language. A message from a user regarding this: I am using Windows 2000. When I evaluated the software, I have my locale set to English and it WORKED. But right before I register to the software, I changed my locale to Traditional Chinese which failed the program while opening the file. So, after setting the locale and language back to English, it works.
