I don't understand MIDI that much, but there are 187 voices (excluding XG voices) and 18 drum kits in PSR-E343. The thing is I wonder whether I could access all the voices and drum kits by using sequencer software like Rosegarden? I mean I want to make music with the sound is completely from my keyboard. I want to make a drum pattern with Dance Kit from my keyboard too.

I'm really is a newbie. As I mentioned before, I don't know much about MIDI.

Looks like it can't. Thanks.

Update

Hm..., looks like it can.

Not sure, but it may be related to XGlite and GM.

I need to do more research.

Yes, you need to do some research. But, really, it's easy. (Start here: http://www.midi.org.)

"MIDI" is a standardized way for musical instruments to talk to one another. It was invented in the 80's when the electronics that we then had available couldn't do much, but it was cleverly and thoughtfully designed. For instance, opto-isolators were specified, so that stray currents in a studio wouldn't fry equipment, and microphone patch-cables were used because every studio had that kind of cable running through the walls. The messages, too, were very simple: they were single bytes, and the leftmost-bit always marked the start of a new message. It was therefore easy to implement.

"GM = General MIDI" is simply an agreed-upon standard set of musical instrument "patches" that everyone could agree-on, and it was a reasonably diverse set of sounds. Therefore, any piece of electronic music that requested "instrument #14" would hope to get some kind of xylophone sound, and so on. No promises were ever made as to what sort of xylophone-sound it might be, nor that you might not in fact get something else. (Remember, "samplers" would not come along until much later, because for many years that kind of memory-capacity couldn't be had, and disks were "floppy, small and slow." Okay, okay, that's what you've got, so that's what you use.)

Similar standards were then cooked-up for, say, drum sequences. There are many different drums and other noise-makers in a "kit," and there is once again an agreed-upon mapping of "note numbers" to "sounds," so that a MIDI-file has at least some reasonable chance of actually sounding as the composer intended.

Naturally, there are many more options available today. Stages are usually filled with CAT-5 cables and routers today; even Bluetooth. But MIDI is still a standard that is still widely used. (Sometimes, carrying MIDI data on network transports.)

There are plenty of sequencer and so-called "Digital Audio Workstation (DAW)" programs available for making music with your computer, such as Apple's GarageBand program, which comes with every Mac these days, or its big-brother (and my personal "axe"), Logic Pro. But there are many, many more. There are very active open-source projects which produce top-quality software of every description. (Including, for example, "MuseScore," which is a free music-scoring program that does everything I could ever have wanted such a program to do. Rosegarden is certainly another top-flight contender.

You have a very powerful and well-built "music box" on your hands. Learn to use it, and use it well. (Plan on spending many delightful years in this pursuit ...) We musicians have never, in thousands of years, ever had such music-making capability as we do now. Nor have we ever had such options for commercial sales of our work. "Welcome to the obsession."

So I have a MIDI controller and a synthesizer on a simgle device.

But I still don't know how to access all the 550 voices it has.

I still can't access a certain voice of my keyboard via sequencer software.

I don't have a private room and a my own desktop PC so it is just not convenient for learning.

I found a good article page though. hhttp://www.rosegardenmusic.com/doc/en/studio-bank-editor.html

You will need to find a manual on it.   Devices like this one generally are intended to be used through some kind of a computer, but a MIDI-capable keyboard can generate the MIDI outputs that will allow you to play it.

You can always find a way to use "what you have" to make music. Years ago, it involved four-track cassette tape-recorders and electronic noisemakers with lots of knobs on them. It's all the same ... music is there, and you're gonna find a way to make it, without waking-up the neighbors.

As a side note, you can also use a softsynth like fluidsynth and thousands of free soundfonts available on the web. fluidsynth is basically the software version of your synth, and soundfonts are collections of "voices"

Horray. It is actually easy when you have manual. Finally I am using Rosegarden and using that LSB and MSB value to get the sound.

I just need a decent MIDI sequencer for Windows for now. Which could do the same thing like in Rosegarden with banks.

Have you seen LMMS? It's available for all platforms.

Congratulations on your progress! I'm a Mac user when it comes to music, so I can't help you specifically, but I certainly can say that you will very-soon see your way clear to a solution that works great for you. (Despite your operating-system.)

Seriously ... you have "a schwee-e-e-e-et lil' music box" on your hands ... and you ought to get many years of musical enjoyment out of it. Not only as a "noise-maker," but also as a performance instrument.

One thing that you should be "smoking over" at this point is that, very often, MIDI-music-geeks think of "synthesizers" and "keyboards" as two separate things, even if they are in the same box. The keyboard is being used as an input device, to generate a human-performance as a MIDI stream so that it can be captured by the computer. The synthesizer/sampler hardware is used as an output device, at an entirely different point in time. It's ignoring(!) the keyboard entirely, instead responding to a MIDI data-stream that the computer is sending to it.

The PSR-E343 might be what's called a "consumer-oriented" box, but, being Yamaha, it does produce great sounds. (One of my "mainstays" is a Casio box that I bought for 50¢ with two missing keys on its impossibly-tiny keyboard. When driven by MIDI, it produces great music.) You'll be doing a lot of that sort of thing, very soon ... and having a fantastic time. "Welcome to the Obsession."
