as long as this DOC file accompanies the program
So, Bunky, you got a new synthesizer, but it's a module and has no
keys to plunk on to listen to the patches/voices. Boy, have we got
a deal for you! At a very moderate price (free!) we can help you
out. Read on.....
Click on PTCHPLAY.PRG with your MONO monitor connected, and watch
the fireworks..
An alert box will appear to let you know that the program is indeed
MONO mode only. If you have your mono monitor connected, click on
OK...
At the top, you will find a title, a copyright notice, and a plug
for our BBS (now you know why it's free!).
Center screen is the built-in single-note sequencer. There is a
Start button, and an octave offset selector box. If you wish to
stop play at any time, click and hold the right mouse button. The
octave offset selector allows you to move the sequence up two
octaves, and down four. Some instruments/patches just don't sound
good at middle C and this allows you to listen at the full range of
the keyboard.
Next, is the quit button and another set of selector boxes. If you
click on quit, it's desktop time, as there was no reason to verify
the choice. (Nothing is saved or loaded, so why hassle you for
nothing?)
Patch select allows you to send MIDI program changes simply by
clicking on the arrows. Each click sends the change to the
synthesizer, so it can be fun watching the window change as you
hold the button down. Patches less than 0 or greater than 127
cannot be selected, as MIDI won't allow it anyway.
Channel select allows you to select the MIDI channel you want to
test upon. 1 to 16 are the limits (for obvious reasons!).
Volume select is for the volume, 0 being none at all, and 127 being
the loudest. Be careful with this if you are using headphones!
If you have noticed that the mouse pointer is a hand, the bottom of
the screen will explain why. The keyboard is fully active, but not
velocity sensitive (awwwww..). Glissando is possible, hold down the
mouse button and slide up or down the keys. To see what the sustain
curve sounds like, click on a key and hold.
Have fun, if you are fast, you may even be able to play a simple
tune. If you have problems, or wish to donate to the cause, contact

P.S. We have quite a library of MIDI sequences on disk, write for a
catalog.
