README file for Voyetra V-Series driver disk:

******** Notes for DOS users ********

1) You can now use the additional MIDI output ports on your 
V-22 or V-24s as a secondary MIDI interface along with any 
other VAPI-supported MIDI interface. For example, you could 
use 2 V-24s cards to get 8 outs, or a V-22 with a Sound 
Blaster to get three outs.  To get this to work with 
Sequencer Plus, you must obtain SP version 4.11 or higher, 
which will have an install explicitly for this. 

2) If you are using the VP-11 on a Tandy 1800 HD, you must 
edit your DRIVER.BAT file to pass the /tn option to 
VAPIVP11.  Load DRIVER.BAT into your editor, and change the 
line that says something like "vapivp11 /lpt:n %1 %2"  to 
"vapivp11 /tn /lpt:n %1 %2".

For any laptop where VAPIVP11 loads but you have trouble 
getting MIDI input, this /tn option may be worth trying.  So 
far, the Tandy 1800 is the only computer we have found that 
requires this.

3) DOSDRIV.EXE.  Run this file if you wish to install the DOS 
drivers (vapi).  This should only be run if your DOS
software didn't come with a driver for your MIDI interface, or
if you are having problems with the driver that came with your
software and want to try a more recent one.

In most cases your DOS software will have come with the correct
driver.  Your interface manual may have more on this subject.

******** Notes for Windows users ********

1) Some of the Setup dialog boxes have been changed 
slightly, so they won't match the illustrations in the 
documentation exactly.  For the V-22 and V-24s, the main 
Setup box has a new field added: "Rx Buffer". The VP-11's 
Custom Config dialog box has a new field: "Persist".  These 
will be explained below.

2) "Rx Buffer" setting for the V-22 and V-24s.  This edit 
control lets you adjust the size of the MIDI Input buffer 
for best performance.  Previously this could only be changed 
by editing the SYSTEM.INI file. If you are having difficulty 
uploading large system exclusive blocks, you may want to try 
increasing this value, up to 30K or so.

3) "Persist" setting for the VP-11.  If you are having 
trouble uploading sysex information in 386 Enhanced mode, 
try increasing this value to 200 or so. 

If you are running on a fast computer in Standard mode, you 
can get slightly better performance by DECREASING the 
Persist setting a smaller number (i.e.: 1).

4) For the V-24s and V-22, you may now use more than one 
interface in your computer.  Here is how to install Windows 
drivers for two V-24s cards:

a) Install one V-24s or V-22 card and get it working 
properly with Windows.  Follow the directions that came with 
the interface. If you already have one working, go to the 
next step.

b) Install the second card in your computer.  It must be set 
to different interrupts and I/O addresses than the first 
one. Refer to the V-24s/V-22 manual for instructions on how 
to do this.  Note: it may be difficult to find two 
interrupts to install two V-24s/V-22 cards such that they 
don't conflict with some other peripheral in your system.  
As far as i/o addresses are concerned, we suggest you first 
try putting the secondary V-24s at $310.  If you have an 
Ethernet card at $310, try $230.

c) Make sure that the first interface is still working 
correctly.  If not, the second one may not be set to a 
different irq or i/o address.  Also at this point you might 
want to make sure that other peripherals in your system are 
still working.  In particular, you might want to test any 
FAX/modems, modems, serial ports and mice that you have.

d) Now install the driver for the second V-24s.  This will 
be similar to the way you installed the driver for the first 
one, with the following important exception: when Windows 
displays the "Install Driver" dialog box, instead of 
entering "A:\" or "B:\", you must enter "A:\multi" or 
"B:\multi".

If you followed the above procedure correctly, you will be 
presented with a list box containing a number of drivers. 
Choose "Voyetra V-22 Midi card #2" or "Voyetra V-24s MIDI 
Card #2" as necessary.

When you are presented with the Setup box, select the 
address and interrupt of the secondary card.

Now everything should be running smoothly.  You will now 
have to configure your MIDI software to access the new MIDI 
Output ports you have just installed. For example, if you 
installed a second V-24s, when you open the MIDI driver 
configuration window in your Windows sequencer, you will now 
be presented with 8 output ports, four inputs and two SMPTE 
readers from your two V-24s cards, plus whatever other 
drivers you may have installed!

At this point, the Media Player and other multimedia 
applications that use the MIDI Mapper won't send data to the 
second V-24s.  This is probably how you will want to leave 
it, since there aren't many uses for multiple ports with the 
MIDI Mapper.  If you feel like experimenting, go ahead!  
Just fire-up the MIDI Mapper applet from the Control Panel.
