FAQ
How to play melody with Left Keyboard after starting auto-accompaniment?
After starting auto-accompaniment, by default, the
function layout of Left Keyboard will change to "Control + Auto-Chord"
automatically. Then you can use Left Keyboard to change auto-chord, change
voice and change effect. If you want to play melody with Left Keyboard, you
must change the function layout of Left Keyboard to "Melody + Melody" (or
other), but then you can not change auto-chord.
If you would prefer to play melody with Left Keyboard, you can modify options.
Sound delay! (Sound can be heard in a moment after pressing a key.)
Sometimes, it is called Latency. It is independent of HappyEO. Generally, it relate to the MIDI output
device.
 | If use a soft Wavetable (such as winGroove or Roland VSC-88 or YAMAHA
S-YXG) as MIDI output device, the sound delay is much in evidence usually. (but YAMAHA
S-YXG can get little delay by setup it's options) |
| Many MIDI output device based on-board sound card such as Microsoft GS
Wavetable SW Synch, exist sound delay problem, too. |
| Few types of computer keyboard can increase the delay. |
| Some voice, such as some strings, sound delay is it's property. |
If you want to treat HappyEO as a real instrument, a (external) sound card
is recommended.

or sharp note)?
There are several ways to do this:

play #D on right keyboard, you can press SPACE at first (do not release),
then press the key
of D (that is 2 on right keyboard), now sound #D and you can release SPACE.
|
| Use F12 to quick define temporary semi-tone. |

to playback, and reserve 3 channels to play.

own "Karaoke-play MIDI song"?

song and playback, mute (or adjust volume of) the melody channels (tracks) ,
then click "Modify" button, select "Delete muted channels" (or "Change
initial volume of channels to current value"), then click "OK" button.

be used as "virtual piano" in Cakewalk?
Yes, but only available in HappyEO Pro, because only
HappyEO Pro has the ability of MIDI-input. But to be used as "virtual
