I have a Yamaha PSR-500 I think I gave over $400 for.  It's touch-sensitive,
full-sized 5-octave sampled sounds (limited voice editing), on-board sequencing,
Drawbacks:  crude touch response, no midi-output from sequencer, sounds good
but still a notch off of "pro" equipment (appreciate any technical info in this
regard if anyone knows).

What sold me:  I couldn't resist the piano, which BTW is 28 note polyphonic
ALTHOUGH some voices use up 2 or 3 polyphonies per note, which adds up (!)

There are newer machines in this line now, I think the PSR-530, PSR-600.

Hope this helps.

Hello!  I have a PSR-500 and advise you not to purchase PSR-600.  I say this
because the PSR-500 has an incomplete MIDI implementation.  I am assuming the
PSR-600 has the same MIDI implementation.  In the states, I think the PSR-600
must run at least $450.  For this money, get a used professional keyboard,
with FULL MIDI implementation, including velocity sensative keys (both
down and up directions of key), and pressure (after-touch) sensativity.
The only thing you will gain by staying with the Yamaha PSR line is the
intelligent accompaniment features.  If you do not require this (there are
programs like Band-in-the-Box that does this, but not "as you play"), and are
serious about computer MIDI, go to a professional setup, which does not have
to be expensive, and can be purchased a component at time.  One reommendation
is a Roland U-20 whih sells for about $550 to $600 I think, used.  I do
not think you will regret this kind of purchase.  I know people who have
spent $$$ (like $10,000) in MIDI equipment and still kept their original
Roland U-20!  I am sure their are other good used keyboards in this price
range too.

The Yamaha PSR series good for what it does best: an affordable high end
consumer product purchased for the family.  It is not adequate for anyone
who is serious about computer MIDI music.  At the high end of the PSR line
of products, I do think you can make a better purhase with a different
product.

Hello, friends

My name is Pedro Rozo, I'm Colombian and I am a Systems Engineer (Computers),
my hobby is music, (The keyboards). I have a Yamaha PSR-500 and a
DTK 80386 20 Mhz (PC);

  What can I do to connect them?

  I Know boards like Sound Blaster (16,16 ASP) and other MIDI interfaces, but
    they are very very expensive in my country (> $400), and don't have the MIDI

    conectors (are additional and can't be found).

  I need sequencing as well as other special effects (wave events), is possible
    this operations with PC and PSR-500 ?

  I can get more instruments or sounds (MIDI), working with the PC ? or this
    function is exclusive of the sinthetizers ?

  I 'am thinking have a Yamaha PSR-600, is it a good machine ??

  What problems can have with the PSR-600 ??

  but, and other hand : Can i work MIDI with the serial port (RS-232) of my PC ?

Glad to meet you! You're really going to need to get a MIDI interface of
some kind; you may end up having to build yourself one. They're not
terrifically complex, pretty much a current-loop communications port
running at 31.25 (I think that's right) bps.

>  I need sequencing as well as other special effects (wave events), is possible
>    this operations with PC and PSR-500 ?
If the PSR-500 has a MIDI in port and a MIDI out port, you can do
sequencing with it. By wave events, do you mean the playback of .WAV files?
I think you'll  need a real sound board for that.

The PC essentially lets you have a multi-track event recorder (this is
provided by the sequencer software). The PC itself doesn't contribute
anything to the music in a MIDI setup; it just drives the keyboard, as if
were a printer or a modem.

>  I 'am thinking have a Yamaha PSR-600, is it a good machine ??
It depends. Are you planning on building yourself a professional studio,
getting together a rig for playing live, or just on having a new (or
another) keyboard? I don't know the machine myself, so I can't comment on
whether it is good or whether it has any known problems.

Not directly. You'll need something to convert from the RS-232 to the
current-loop stuff that MIDI uses. I see that you're at a BITNet site, so
I'll mail you the MIDI specification privately - that includes the hardware
requirements, so you might be able to put something together if you're
handy with a soldering iron.

You'll definitely need to find those 5-pin DIN sockets for the MIDI plugs,
or else make  modifications to your keyboard to use a different-style
socket.

I apologize for being unable to reply in Spanish. I hope this will help.

   Hello Joe :-)

  I wonder why didn't You reply to my 'RS-232' mail. I was wondering
if it's possible to use RS-232 in PC as MIDI input/output. I got
response that there is a problem of the speed of data. I have Amiga's
interface which runs on RS-232 that isn't different from a PC.
   I have 386dx/4Mb with Cubase and no MIDI. I surely would be glad
to check out PC for it's MIDI capabilities, if there is a cheap way
of using what I got/making an interface please write some info.
I'm little (total amateur) in electronics that is I know what an
condensor or resistor is... :-)

Hi, Jack. I know that there are boxes that can hook onto the serial port
and provide MIDI - the Kee Electronics one being the one I remember a
little something about. Heaven knows how complex a box it is inside,
though. Here's the small part of the electrical specification from Bob
McQueer's MIDI Primer document (out there on castrovalva.gsfc.nasa.gov):

--------- snip ---------

ELECTRICAL SPECIFICATION

Asynchronous serial interface.  The baud rate is 31.25 Kbaud (+/- 1%).
There are 8 data bits, with 1 start bit and 1 stop bit, for 320
microseconds per serial byte.

MIDI is current loop, 5 mA.  Logic 0 is current ON.  The specification
states that input is to be opto-isolated, and points out that Sharp
PC-900 and HP 6N138 optoisolators are satisfactory devices.  Rise and
fall time for the optoisolator should be less than 2 microseconds.

The specification shows a little circuit diagram for the connections
to a UART.  I am not going to reproduce it here.  There's not much
to it - I think the important thing it shows is +5 volt connection
to pin 4 of the MIDI out with pin 5 going to the UART, through 220
ohm load resistors.  It also shows that you're supposed to connect
to the "in" side of the UART through an optoisolator, and to the
MIDI-THRU on the UART side of the isolator.

>>
        I'm not much of a hardware person, and don't really know what
        I'm talking about in paragraphs like the three above.  I DO
        recognize that this is a "non-standard" specification, which
        won't work over serial ports intended for anything else.  People
        who do know about such things seem to either have giggling
        or gagging fits when they see it, depending on their dispos-
        itions, saying things like "I haven't seen current loop since
        the days of the old teletypes".  I also know the fast 31.25
        Kbaud pushes the edge for clocking commonly available UART's.
<<

-------- snip ----------


That's about as much as I can tell you, being a software and not a hardware
personage, and a Mac one at that.

Dear frieds:

  I have a YAMAHA PSR-600 now, the reasons for the change:

   1. I need store my sequence and my compositions; but i need
      moving the keyboard for play music in diferent locations.

   2. With the PSR-600 the work can store in diskette 3 1/2 compatible with
      the format MS-DOS (for PC'S).

   3. I want to Know an other persons which have keyboards PSR 500/600 for
      compart experience.

   4. Somebody Know the format of Page Memory of this Keyboards ???
      (This formats can to be read in PC'S).

   5. Somebody know where can to meet rithms (Salsa, merengue, balada pop, etc)
      with sequences for this keyboards ???


Thanks.

I have a PSR-500 connected to my Mac Classic II using Beyond and various
shareware.  Works great.

Most pleased by:  nice piano and strings for the price
Dissapointments:  clumsy touch response, no midi output of onboard sequencer

Nice kb for the itinerant non-professional musician.

I would love to know:  How can I get more detailed engineering data?
For instance, does anyone know the data structure for the SYS DUMP? (not
given in the manual.)

Would love to use the onboard sequencer to write a tune, then download that
to the mac, do some editing, then pop back to the PSR-500.  Currently I
compose using the kb and sequencer together, but sometimes, by the time you
get the whole mess working, you're not in the "mood" anymore.  I generally
get around this by just leaving the whole setup running for days at a time;
in fact, I virtually never turn my Mac off; so when I feel like tickling the
plastic (so to speak), and I come up with something nice, it's pretty quick
to save it on the computer;  often I use one of the small shareware sequencers
like MiniTrax or Midi Companion to kick out a quick midifile for later
editing and manipulation.

I can honestly say I have learned a huge amount about music from a string of
inexpensive keyboards; sure everyone would like a Steinway or a Stradivarius,
but that's the beauty of music - all that's really required is
a heart and an ear - and nothing beats a nice one of either.

   I had this model and sold it about year ago. My friend still has it.
>From what I recall whan You hold MIDI and press first button on top
in 'orchestra' the left voice is I think MIDI receive channel and right
MIDI transmit channel. When you press MIDI button and Calliope than
it means external clock on/off. I can check it if You want it for sure.
When you select MIDI and transmit/receive...each key on keyboard from the
left means a channel. First ch1, second ch2...etc.

Hope this helps.
