Hello
The audio must be recorded via your audio-interface. To sequence
the notes, which the DX shall play you need a MIDI-interface for
your computer. I definitely advise against a "USB to MIDI cable",
those usually do not work reliable. Get a proper standalone MIDI /
USB interface.

Hello,
Just bought
an used DX7 and my question is about how to hook it up in logic
pro x to record. Can you use a Midi to usb cable? Or do i just
use the midi conections and the audio out in to my interface?

You can't connect midi to audio they are totally different things (the first is digital communication, the second is analog audio).
A USB Midi interface is your best bet.

Re: Hi All... On a different topic..... assistance needed.....
The problem is your first or second gen ipad. The DX is fine.? The interface is fine.? Your iPad doesn’t have the smarts to deal with BT and MIDI and if it’s 1st gen, as was mine, the opsys can’t be updated far enough. I know this because I went through the same thing a year or two back.? iPad running Korg suite. Was stuck running the midi-to-30pin adapter. It was my wife’s “old iPad” so I put it to good use.? But the gig wasn’t enough to shell out the clams for a newer one. ? L. ?

Re: Hi All... On a different topic..... assistance needed.....
I was a MIDI Solutions dealer for many years, and learned to deal
with this problem all the time.? The good news is that older MIDI
gear is more likely to work than newer gear -- at least, from a
hardware perspective.? The original (1982) MIDI spec shows suggested
In, Out, and Thru circuits, and they all run off 5V.? Over time,
electronics has moved to 3.3V and lower, making it harder to provide
enough voltage to provide "MIDI power" -- which does NOT actually
have a standard!
I would bet that the DX7 provides 5V power; my TX802 does.? If it
does not, then the other culprit is that the shell on the Out jack
must be tied to power ground.? Again, the 1982 spec shows Out and
Thru cables tied to ground, but In cables left floating.? 95-99% of
devices follow this convention, but I've seen a few that don't.?
Fortunately, it's an easy fix:? just solder a wire from Pin 3 (the
middle pin on the DIN jack) to the shell pins, or to PCB ground.

Re: Hi All... On a different topic..... assistance needed.....
I see this guy has posted a video on YouTube about connecting this so you might want to watch that to make sure it is connect correctly. Then I would test getting your DX7 to send notes to a software synth, when you get that working then I would work on transferring patches (sysex). Not all devices that handle MIDI connections can handle sysex transfers so you might want to see if Yamaha say it can do sysex. One suggestion is to use Dexed to transfer sounds to your DX7, it is a software synth that emulates a DX7 so you can audition the presets and it also works as a Librarian so you can transfer patches back and forth. Hope that helps.

Re: Hi All... On a different topic..... assistance needed.....
David,
Unless you've seen instructions that say so, I wouldn't assume IN on the device goes to IN on the synth, in fact I'd assume the opposite, because that's how MIDI devices are normally labelled - IN normally means MIDI IN to this device, and OUT normally means MIDI OUT from this device.
I have an M-Audio Uno, which as built in MIDI leads labelled "To IN" and "To OUT", which still tends to confuse me because I don't always notice the "To" if I haven't used it for a while.

Re: Hi All... On a different topic..... assistance needed.....
A couple of 'startup' questions and general comments --
- Does that iPad recognize that a BT MIDI device is connected??
If so, the MD-BT01 is probably plugged in correctly.? (From your
description, it sounds like this is the case.)
- Set the MIDI channel to CH1.? Do you have a program that can
monitor MIDI traffic?? Can you send/receive notes?? (On a PC, I
use MIDI OX; I'm not sure what/if the equivilent program on an
iPad is.)
- MIDI SysEx doesn't have a channel per se.? Devices send an F0
byte, the Manufacturer ID (either 1 or 3 bytes), and end with an
F7 byte.? In between the Manufacturer ID and the F7 can be a
string of bytes defined by the manufacturer, and may only work
with certain products.? There *may* be other tags such as the
Model ID and Device ID (number) to define compatibility or
direct traffice, but these aren't absolutely required to be a
SysEx message.? Some of the gritty details of SysEx were being
flushed out while DX7 was being released, so it wouldn't
surprise me if it cuts some corners in this respect.
- The biggest potential hurdle is connecting the BT MIDI to
editing software that supports the DX7.? Many older MIDI
editor/librarian programs only work (or work well) with specific
MIDI interfaces.? I doubt that something as comparatively
complex as Bluetooth MIDI was part of the discussion.

those two. And that although they use the same
MPU (HD63B03XP in DX21
and HD6303XP in DX27S),only difference is the
speed of the processors.
Okay, now I have a reason to desolder the rom
from my DX27s and read
that out... Unless someone has the firmware of
the DX27s?
Cheers, Florian

How do you interpret the voice data from the firmware? Maybe I don't need to desolder my ROM after all...
The total size of that bin file is 32768 bytes (0x8000) I checked the file with a hexeditor. The voicedata start at address 0x4da0 Each voice uses 67 bytes ( = the first 67 bytes of the 128 bytes VMEM voice parameter bulkdump format, up to the 10 bytes that contain the voicename. You can find detailed description of VMEM format in the DX100/21/27 etc. manual. Many of the unused or reserved bytes in these 128 bytes are used in the later models, from TX81Z and DX11 to YS200 and V50. ) There are 192 patches. 192 x 67 = 12864 bytes After that, starting at address 0x7fe0, there are 32 bytes ending the file. 67 + 12864 + 32 = Address | Size --------|--------- 0x0000 | 19872 firmware data 0x4da0 | 192 * 67 = 12864 bytes voicedata 0x7fe0 | 32 bytes ========|========+ 0x8000 | 32768 bytes Does that help ?

Re: Hi All... On a different topic..... assistance needed.....
The setup video on the yamaha site doesn't really indicate which plug
goes in which socket - hopefully that is evident from the way the loop
of wire is between them,unless they are marked. I
doubt you should need an app to connect bluetooth - that's in SETTINGS
on the ipad,and Yamaha are referring to something called PIANO DIARY
which I presume is a music app,and to select the comms device within its
settings. To edit the sound parameters on the DX7 would need some sort of SYSx dumping software on the IPad and the instructions Grant just provided.

thanks a lot, that is great. But from a first check, the DX21 firmware and that of the DX100 are completely different. In the DX100 the rom starts with code and ends with the voices, in the DX21 it's the other way round. Also the DX100 uses only 43 bytes per voice, so no simple direct comparison between those two. And that although they use the same MPU (HD63B03XP in DX21 and HD6303XP in DX27S),only difference is the speed of the processors.

Check the usual suspects .... have you enabled Sys Ex on the DX7.
Press FUNCTION 8 button and set SYS INFO AVAIL

Re: Hi All... On a different topic..... assistance needed.....
I do not think the DX7 is too old as MIDI is just a? protocol (although I heard MIDI2 is in the pipeline) . I would check the instructions of the Bluetooth device as nominally in MIDI, IN goes to OUT and vice versa,not IN to IN and OUT to OUT,it depends on the way the cable has been labelled. On the basic DAW set up diagram shown on this page,you can see IN going to OUT and OUT to IN. If you are experiencing no data,possibly the ca bles are in the wrong sockets.
One of the possible drawbacks of the MIDI spec is they did not make it impossible to get the cables back to front.
