TX7 Web Resources

I dig this little synth and its funky wedge shape. I have used it with heavy filter effects for creating some truly bitchen sounds. the down side is that it is not rack mountable but I found a slot under my effects rack that it tucks into nicely in the studio. Although it was originally intended for use with a Yamaha DX7 Keyboard as an expander module it works great as a stand alone synthesizer in conjunction with a sysex editor/librarian and a personal computer you can produce a wide range of sounds. Even with a simple midi librarian you can now down load literally thousands of pre-made patches off of the internet even though this little guy will only handle 32 at a time. The big difference between the two Yanaha machines besides the fact that the DX7 has a Keyboard is that the TX7 has analog filters with their rich warm sound and the DX7 sounds sterile and anemic with its feeble digital audio filters.

If like me you have an older slower computer system (My computer is a Pentium 2 at 300 MGZ) then outboard hardware may be your only option. Software synthesizers are great and have allot of bonus features like filters that can be controlled in real time that the original hardware machines did not have but all this stuff taxes your Computer's memory and run time or may not operate on your system at all. Check the system requirements before you buy and remember you can do a lot more with the vintage gear nowadays than the designers had ever dreamed of by interfacing with your computer and the right midi tools, and a good midi sequencer. If like me, you are working with this type of hybrid system you can find some great deals on used software and hardware online as the new versions are released the older synthesizers, and applications drop in value drastically.

I will explain the process for those unfamiliar with these old machines. First thing to remember is that in the early 1980s there was not a world wide web and personal computers were not a thing like we have today. My first computer was a Comador Vic 20 with about 5 K of memory and no midi ports. (Midi is an acronym for Musical Instrument Digital Interface.) To get midi you had to buy the Comador 64 that came out some time later. My Vic 20 had a cassette interface for saving programs on to an audio cassette tape, no floppy or hard disk. This meant you spent hours of programing to get the machine to do something interesting and then when you tried to save the program to tape it wouldn't work half the time and you lost your program!

Both of my main midi synthesizers the Yamaha TX7 and Sequential Circuits Prophet-5 have a similar cassette interface. I have had very good luck with the Prophet saving Sysex (System Exclusive data) to cassette tape. In fact I have to because it will only send one patch or (sound) at a time over the midi cable as SysEx, there is no implementation for a bulk dump from the Prophet. The Yamaha TX7 is another story completely, all thought it has a DIN connector on the back of the unit for connection to a standard cassette tape machine I have never used it. Sending SysEx over the Midi cables is far faster and more certain. Plus you can save thousands of patch setups on your computer and instantly transfer them to your synth at will all be it 32 patches at a time with the TX7 synth. There is even a way to do this with computer midi sequencers like Cakewalk so that your particular patch settings or voices are stored with the midi music file and transferred when you play the file. The other advantage to transferring SysEx over the midi cables is that you can use a MIDI Librarian/Editor application to store, index, search files and edit Banks of patches by moving patches from one bank to another or with some of the more powerful editors you can even create new sounds from the program on your computer and load these to your synth.

I have provided a few links below to several sources of SysEx files for the TX7 these will work on the DX7 keyboard as well. The files are compressed in ZIP format, so you will need to unzip them with Winzip after you down load them. Once unzipped you will find Banks of 32 patches each (Yamaha calls them algorithm's). You will need a program like Midilib to load these from the computer to the synthesizer. If you have Cakewalk click on VIEW from the top tool bar and scroll down to Sysx and click on that. You will be able to open a sysex file and send it but first make a copy of your synths bank of patches and save these on your computer. Loading files over writes the RAM memory and there is no reset button or factory patches stored in ROM to be recalled. Cakewalk has a DRM for the DX7 just scroll though the memory to find it. If you have a different sequencer program poke around in the tool bar you probably have a similar Sysex function. MidiLib is a little more robust than my Cakewalk Pro Audio 8 utility in that it reads the patch names and displays these along with the patch number just like you see in the little LCD screen on the TX7. Also it is much easier to shuffle the patches between banks with midilib.

If you load new patches into your TX7, the existing patches will be over written, so make sure you have backed-up your patches first! Read and understand before pressing any buttons on the TX7.

MIDILIB can be down loaded for free from this page below in the Midi Tools section. MIDILIB is a Yamaha DX7 librarian (a library of sound patches, rather than books), that includes the function for transmitting and receiving system exclusive data to an external device. You will have to switch 'memory protect' on your synthesizer to 'OFF', so it will accept the system exclusive stream of data. To do this on the Yamaha TX7 press shift on the synth, then press Load Port, the LCD screen will display Protect ON, now press NO -1 key, and the display should read Protect OFF, now you are ready to receive sysex data from your computer. After the the process is completed turn the TX7 off and then back on to reset the operating mode.


Owner Manuals Yamaha Owners Manual library
Search for TX7 or look in Category - Clavinovas Digital piano. You will find the original manual and performance notes here in pdf file format.
I had a tuff time finding a manual for my Akai ME 30P midi patchbay so I have placed a copy of the pdf file here just in case you need it. A midi patchbay allows you to hook up all your midi in and out cables to one patchbay and then change the routing by a selector switch or as is the case with mine changing the program number. The Akai ME 30p stores 15 different midi routing programs so just push a button instead of pulling out midi cables and plugging into different machines. With one setting I can play the controller keyboard and record the midi data to my computer while listening to the synths. With another program I can play the synths directly with the computer turned off. If you have more than one synthesizer and or midi controlled effects gear you need a midi patchbay to make your life easier.

I should mention here that this old 1980s way of routing midi data and organizing synthesizers only works on 16 channels of midi, 1 through 16. The newer USB 2.0 midi interfaces and software can make a second bank of midi available or a total of 32 channels or even more like 64 or 128 channels. USB is great for modern synth gear and sequencing software but does not apply to vintage gear.

In 2009 I added a second midi patchbay made by another manufacture to my system, the number of synthesizers has grown in my studio. So I now have a midi patchbay in a cabinet routing the gear in my midi rig to and from the Akai ME 30P. The Akai ME 30P also routes the sequencer computer and the synthesizers on the other side of the studio. I should probably mention that the Akai ME 30P does not have a midi merge feature and this can be a major problem in creating a midi rig or outfitting your studio. Akai did make another similar model called the ME 30Pe which had this merge feature. The basic idea of Merge is that the midi patchbay will mix or merge the midi signals coming from your sequencer and a controller keyboard. In my project studio The Tiki Room, I have a Studio Logic SL-161 midi keyboard plugged in to a keyfax Phat-Boy midi controller plugged into channel 2 of the second midi patchbay, and the computer sequencer is plugged into the 1st channel of the second midi patchbay. These two channels, 1 and 2 are merged and then routed to the midi outputs that feed my synthesizers located on the North wall of the studio. Also the Phat-Boy does its own midi merge between itself and the midi keyboard plugged into it.

A cool collection of tidd bits on old synths with current market value and reviews.

MIDI Tools:

Instrument Definition
I have written a Cakewalk Instrument Definition for the SCI Prophet 5 synthesizer. I believe this file will also work with Cakewalk's SONAR sequencing software. You will find a link to the file in the Prophet 5 Resources page on this site. The file allows your midi sequencer software to send and receive patches via sysex data.

Get Midilib MidiLib is a simple Midi librarian editor for Windows that is configured for the Yamaha TX7-DX7 as well as 3 other synths; Kawai K1, Roland D110, and Ensoniq Mirage. This a beta version 0.1 from 1996 so it will work on your old PC in fact it will run from a floppy disc its so small. I have used midilib myself for quite some time now with great success. Just down load and unzip and you're ready to go. Instructions are in the readme files. 12-7-2003 UPDATE: I heard from the author of midilib Jim Orshaw. He informed me that this is the last version he released. Thanks Jim!
Get DX Manager DX Manager
DX Manager by Jon Morgan.
DX Manager is a general-purpose editor and librarian for the Yamaha DX7 and compatible synthesizers. This includes the original DX7 Mk1, the TX7 tone generator and any other compatible 6 operator DX/TX series synth. DX Manager will run under any Windows operating system from Windows 95 SR2 on. To use DX Manager with your DX7 you will need a hardware MIDI interface such as a Creative Labs Soundblaster soundcard. The download includes over 1MB (10,000+) public domain voices (Patches), all sorted and with no duplicates. Please note: Testing of DX Manager has been limited to the MkI and MkII DX7s and the TX7. Download v1.1 Freeware as of May 2004.
Mark of the Unicorn UNISYN
Fortunately I was able to purchase a used copy of Unisyn 1.5 on ebay used. From what I gather it was the only stable version of this software made for Windows machines at the time. MOTU's Unisyn has a powerful graphic voice/patch editor and comes equipped with plenty of profiles installed for tons of synthesizers. making it possible to organize all, or most of the older midi equipment in your studio. Unfortunately MOTU does not provide updated profiles for new synthesizers or much support at all. I rarely use my copy of the software these days. The main reason is that Unisyn saves it's files in Unisyn's dialect of sysex and since I started with Midilib my files are all in Midilib's dialect of sysex. Plus it aint easy to make good sounding mods even with the powerful editor of Unisyn on your funky TX7 sound banks. But when I can't find the sound I want anywhere else it is nice to be able change the TX7 sound with Unisyn even if it takes some work and head scratching. Bottom line if I were in the market for a new midi editor / librarian today I would look at Midiquest from SoundQuest with all those profiles pre installed it is a great midi tool box if you work with many different modern synthesizers and SoundQuest provides updates and can open standard sysex files.
Hubis loop back HUBI´S LOOPBACK
Lets your Midi software talk to each other. Hubis does not work under WIn2K/XP. Please us MIDIYoke. MIDIYoke can be obtained as part of the MIDIOX package.
Midiox reads your midi data in and out from the computer. It can read your synths data too. This is a Freeware utilities sysex editor / librarian for Windows 9X machines.
FM7 Softsyth FM7 SoftSynth
FM7 is a software version of the DX7/TX7 plus allot more. If you have a 1GHZ machine or better this may be the way to go. I've not tried it but it looks like a pretty cool application form Native Instruments for MAC, PC, or VST plugin.
