piz midi plugins (windows/linux/mac)

[sinkmusic]

THank you for all your work, IPH.
I am wondering : i have an old FM expander which doesn't respond to midi CC but only to Sysex : would it be possible to make a VST plugin sending Sysex ?
Like a "midiCC to Sysex" translator ?
I guess it would be also very depending on the host, but I know Reaper can send SYsex

[insertpizhere]

if it uses sysex as a continuous controller, that could be complicated, but i have some ideas. is there some documentation of the sysex for the device you want to control? that would give me somewhere to start... i don't have anything myself that uses sysex.

to get around the host (some hosts including energyXT ignore sysex), i would make the plugin send it directly to a midi port.

you could do it and you'd be up to do it ?


The unit is a Yamaha TX81Z, it is an 80's FM synth.
Programming it is a bit like setting a casio watch to the correct time, but i like that raw sound... I think many people still have theirs, and i think that if we can make a VST controller device for it, it oculd be helpfull for people owning a=other Yamaha FM synths (like DX78, TX802, etc).
I have found a standalone controller but it needs javascript and it is not a plugin, so no interaction with a host and not midi learnable stuff... So a vst plugin would be a nice nice nice addition

Here you can find some editors for it (no vst plugins), mayeb you can grab some useful techie infos :

You can find the manual here :

The sysex infos are at the end ;

Big thanks for agreeing getting a bit into this !

sink is the sysex transmited one way? Or can you use say MIDIox to snag the sysex messages? This would probably make implementing controls in a plugin a 1000 times easier if at all possible..

i downloaded jsynthlib and i'm looking at its output in midiox... it looks like the parameters are usually 7 or 8 bytes of sysex, where only one byte is the actual data. that means a CC could probably be mapped to a parameter directly.

what i need to do is look for some format for a file for the plugin to load that defines the sysex implementation for a device. i'm sure this has been done numerous times before...

another thing to consider is that synthedit 1.1 will have sysex support, and will probably make it trivial to do what i'm planning. but i'm going to try it anyway.

here's a quick proof-of-concept sysex plugin.

http://thepiz.org/xt/midiCCToSysex.zip

by default it uses CC1 to control the LFO speed of the TX81Z. as it is, you need to manual and a binary calculator to be able to set it to something else, but it is possible.

parameters:
Byte1-Byte8 - manually set individual bytes, starting with the manufacturer ID (F0/F7 start & end bytes are added automatically).
LastByte - sets the byte that the CC will be applied to. bytes after this one aren't used.
LowVal/HighVal - limits the possible values for the parameter
CC - which CC to use
Device - midi device to send the sysex to

Urgh
Thank very, very much, Piz. I can't really believe it : i asked that yesterday and something is already here today
But to be honnest i must say i feel quite embarassed : it sounds a bit like chinese to me, i am not really a byte guy
I have took the Tx81Z manual, and i don't really understand how to use it...

The value i wish to be able to use are the "ACED" data (operators attack, decay, the LFO speed, etc).
On PAge 73 of the manual, i see a table where the parameter numbers are labelled from "1" to "74", and i see nothing labelled as "bytes".
In example : according to the manual, the operator 1's rate scaling is ACED parameter number 6.
I have read the previous pages, they are full of figures, and i must say i don't understand anything (oops + urgh again : sorry for my un-knowledge, i really feel dumb !).

If you can provide me some more info, i'd gladly try, but right now i have the Tx81z powered on and the vst pugin loaded , i am tweaking the faders, but of course as i am tweaking it blindly, it does nothing

CHeers !
(and muchos thanxx again)

here's something that should be more user-friendly. all the allowed values are defined and named in a separate text file.

That is crazy! Thanks IPH

[sinkmusic]

Yes, it is both crazy and very kind.
This one is indeed more user friendly, but i still didn't manage to make it work

In fact, i think i understand the upper part, but i don't know what to do with the "data" fader and the 3 faders below...




Btw, if you wish to, as i tend to like GUI in order to make the plugin even more user friendly, i was thinking of a tabbed interface like this :
This one is dead ugly, done in 5 minutes in Paint.net, but If you want, i can make a better one tomorrow (if implementing it doesn't mean too much work for you and if you wish to) ?

for choosing the sysex to send, the only things you can change are the "parameter" and the "basic receive channel". the "data" is controlled by the incoming CC. i suppose i could make this control send the data itself. right now it only sends sysex out when it receives the CC.

i can't do a real test of it here, so it could be that it simply doesn't work... do things like jsynthlib work for you?

anyway, once we verify that it actually works, i'll add a gui. i'll probably use your layout too.

- Beat-synced midi sampler/looper (amazing version)

Hi IPH was just wondering when this version was released??

[insertpizhere]

looks like january 3rd.

[Optomadic]

Wow ok that was a while back I think I must have it then..

BTW I was wondering if you had a chance to take another look at probability. It still needs a certain randomization for either the probability or the steps. I'm not too sure if this is what will give the probability a randomised feel .

Anyway let me know

Thanks again

i'm still not sure what you mean. like a random lfo applied to the step or probability parameters?
