To check TX81z midi implementation chart, and if it does not respond to midi cc messages for parameters of Your interest, then You will have to use system exclusive .

thanks!, knew you'd say that

sadly being a newbie to Max i've been looking for some very basic help to get me started on the syses procedure :-/

I see, so the stuff You'd like to control would need sysex. That should not be a big deal. Did You have a look in the sysex chart ? In max it will be easy to send sysex strings via midiout object. A very handy way to detect sysex string for parameters is to use some editor which allready has all the stuff ready, and insert Max as midi through in between, and then capture the midi stream. I'll be glad to help You to get further.

yep located sysex chart in manual. am familiar with midi in Max

if u have a spare moment that would be fabulous

:-)

Sure, just post whatever questions or patches which need assistance. I am on tour and so can't log in very frequently, but as soon I get time I tend to do so... There are many capable people here on the forums which can help You as well.

thank u!

just need a very basic outline of how to send a sysex message to the TX18Z to change the attack values of Operator 1, from that i can work out the rest for the other parameters.

:)

I don't have the TX manual, so I can't give You the string. Usually You start with Sysex Start (F0), Manufacturer ID ,Device ID, parameter ID, Value end whatever is needed and end with Sysex End (F7). In Max easiest way is to create a message containing decimal numbers for example 240 instead of f0 and so on and insert $1 for parameter value. Connect that to iter, followed by midiout, and of course a slider or whatever to change parameters... I am sorry to be somewhat short, I just have to leave in a short time. Maybe You could provide download link for TX manual. or upload a page of it here. I 'll be back tomorrow.

Cheers

okay, thats helpful am slowly understanding in good time a copy of the manual attached to this message chat when u have more time, very much appreciated!!!

envelopes and gain should be controllable by CCs very easily.

Had a look into Yamaha manual. I can understand that it is a bit confusing, on some places one gets binary, on the other hex, than decimal. But it is not that complicated, once You get their logic Here is a patch with 2 parameters that You wanted for OP1, and few words of explanation.

A bit unrelated, but have you looked into the stereoping controller? It's a LOT of fun to control the TX81Z with it, and also it will accept midi CC for each parameter (it takes care of the sysex thing).

In my opinion a must buy for tx owners.

thank u so much thats very helpful!

okay, I've tried setting this up without much joy Max has been set to the correct MIDI channel it must be something to do with the sysex settings on the TX81Z?

the other issue I've come across is the program change message in 'Performance Mode'

currently got a pgmout object successfully changing 'Single Mode' presets but not able to do the same in 'Performance Mode' :- /

hi source audio,

sorry to bother u again! i've not had much joy setting up the patch the tx81z unit is set to midi ch 1 the Max midi out object is set to the usb connected to the tx81z (as per screenshot) nothing happening yet on the tx81z when checking the relevant parameters

look forward to your reply when u have a moment

:-)

Are You sure that USB midi interface You use supports sysex ? Most of the cheap so called midi cables don't Could that be the problem ?

hi mate,

yeah i thought about that, could be the issue with old kit vs usb midi

:-/

any recommendations as to how to solve the problem?

thanks!

As first I would check that interface. Simply plug midi cable in it's in/out, send some sysex to it and check in Max if anything gets back. If not, than You need a working interface

I've been using one of these: Miditech MidiLink Mini interface MIDI/USB - apparently not very reliable!

have been recommended the following: Roland UM-One USB to MIDI Interface

at the moment i'm running a cable directly into the tx81z

sysex might also be turned off / filtered in the midi manager of the OS.

Search no longer, that midi interface is not capable of sysex data communication. Same Chip has been used in numerous midi cable interfaces, they even can't send and receive polyphonic notes reliably.

didnt i recently posted that little input helper for hex strings to the forums... i cant find it back.

yeah that cable is rubbish, howabout the 'Roland UM-One MKII'?

I've setup the TX81Z in midi manager on my Mac OS 10.11, there's a blank box for System Exclusive ID would that assist?

i could splash out on 'MOTU MIDI interface micro lite' to solve the problem?

just done a bit of online research

yeah the 'Roland UM-One MKII' looks okay

:-)

Motu USB interfaces will work, fastlane having 2 In/out ports works fine, and is small enough if You need a portable solution. One can get one second hand for 20 -30 $

thanks mate! ;-)

The easiest way to control a TX81Z with Max is to hack into the Kat.Opfour max for live emulation, pretty sure it has full sysex control tucked away in the patch, plus the interface is already built for you. I did it that way for a while, but now I just use Kat.Opfour, which sounds almost identical to the hardware...

https://www.ableton.com/en/packs/classic-synths/

how much does ableton cost with that synth pack then?

abletons not mate

Pack is free. Maybe you can extract a patch from it without Live, not sure.

think u still need to install max for live into albeton so thats double costly?

if you don't have Live, you could use this. just open the amxd in Max http://maxforlive.com/library/device/2202/tx81z-editor

thank u

that looks promising and something to get stuck into

will no doubt give me ideas

;-)

@ Source Audio

would one these be sufficient: Focusrite Saffire Pro 40 Firewire/Thunderbolt Audio Interface

currently on sale, has plenty of functionality for IN/OUT plus MIDI connection and Thunderbolt!

let me know, cheers!

I would say that it will certainly be ok, that problem with sysex is happening only on cheap midi cable interfaces which have shity chinese chip and not enough buffer on it to do sysex or any other serious data transfer.

thank u, that's helpful :-)

right then, am getting to grips with this slowly, a quick query...

@source audio

in reference to the following on page 67 of the tx81z manual: PCED (Performance parameters) ggggg = 00100 (4), hh= 11 (3)

I've attempted to setup a new message box in Max with this:

240 67 16 19 8 $1 247 (19 being the decimal PCED group and 8 being the Vol parameter output for INST1)

however, this message ends up changing the waveform of operator 2 in play single mode..????

hope u can advise if not to much trouble (fingers crossed)

Paul :-)

Hi Paul,

I guess it is due to bin - hex -dec conversion. Here is a simple converter

I don't have TX manual to look into at the moment

thank u!

Could it be that Yamaha manual has mistake in Sysex description ? They state same value for ACED and PCED, which can't be correct. The string You posted 240 67 16 19 8 $1 247 shoud affect operator 3 and not 2

Would You try this one : 240 67 16 26 8 $1 247 That is TX802 PCED that works.

Not sure how PCED works, I use single mode and use VCED and ACED

you can change try changing volume of Operator 1 with VCED message

240 67 16 18 49 $1 247

exactly, i'll try what you mentioned later today, thanks again mate!

> Could it be that Yamaha manual has mistake in Sysex description ? They state same value for ACED and PCED, which can't be correct.

If what I was told (by someone who worked for Yamaha) is correct they made a complete blunder with note-off messages. And because the DX7 was so popular the rest of the world had to follow 'em.

So I'd say YES - they're absolutely capable of making mistakes.

anyone familiar with Sysex messaging for the Nord Rack 2?
