>>> Voyetra V-series Midi interface drivers >>> for VP-11, V-22, V-22m, V-24s, & V-24sm >>> for DOS, Windows 3.1x & Windows 95 Please keep in mind that our internal interfaces use jumpers for Interrupt (IRQ) and Address (I/O Port Address). These are not "Plug and Play" nor software configurable, but the drivers need to be matched to the jumper settings on the card. ******** For Windows 95: ********** VP-11 has no Win95 driver (the Win 3.1 driver may work in Win 95; you may need to remove your printer driver initially) V-22 drivers may have problems with the Win95, so use the Win 3.1 driver (it should work well) V-24s drivers should work well, but in case of trouble in Win 95, you can install the Win 3.1 drivers instead. >>> Browse to the A:\Win95 directory when using Control Panel / Add New Hardware (no auto. detection) / Sound video and game controllers / Have disk Browse to the \Win95 directory on this 'disk image'. The default settings for the interface are used, and you cannot change them until you have installed the driver. At that point, go to Control Panel / System / Device manager / Sound video and game controllers / Voyetra V-24s / Properties / Resources > and Change Settings for the Resource you need to change. Note: the V-22 / V-24s list IRQ 2 on the Jumper Settings, which equates to IRQ 9 on our driver. (IRQ 2=IRQ 9) ******** For Windows 3.1x: ********* This disk image is designed for straight-out Windows 3.1 use, as long as you go to the \Win31 directory. Control Panel / Drivers / Add New or Unlisted Drivers - browse to this \Win31 directory. ******** For DOS: ****************** The DOS drivers for VP-11, V-22, & V-24s are in the \Dos directory. The DOS drivers are meant for Voyetra's "Sequencer Plus", and the few DOS programs that supported Voyetra's "VAPI" driver system. For testing, the Miditest diagnostic program is a wonderful DOS test that can assure that the interface is functioning properly. The DOS drivers have various options, which can be summoned with the " /?" switch at the end... ...such as vapi24s /? (by the way, the undocumented " /enh" switch may allow the interface to operate out of a Windows DOS box if it was loaded before Windows' bootup) ********************************************************************* 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 3.1x (& 95) 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. NOTE: These MIDI Interfaces were designed for DOS and Windows 3.1. They may not install or perform as expected in later Operating Systems.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
