Many thanks to both of you.
Trog, I am sure you a right. So we have to wait for a new release of FS, hoping that this big bug will be fixed.
I have to confess that, remembering the 64bit problem, I can’t feel very optimistic (moreover three emails on the matter to the dspr support without any answer ...

This issue is becoming a nightmare.
I have tried not to use the StrSysex primitive, writing a very simple Ruby code, the same shown at pag. 205 of the FlowStone user guide:

m = Midi.new "F0411000006412180020250023F7"
output m

and I have got the same results: the standalone (exe) version works, the ...

Fingers crossed!
Thanks for your fingers crossed , but I haven't found anything.
All the old archive's files dealing with sysex messages simply use the StrSysex primitive but there is no mention about the fact that they have been compiled as standalone or as VST.
Some files and many posts in the ...

Here's a very simple project I built to control a Teensy-based MIDI controller with a few bytes of system exclusive messaging. (The controller is just a box with a Teensy and some 1/4" sockets for up to three foot-switches and two expression pedals - since it's Teensy-based I'm calling it 'Footsy ...

Hey,
If you check the old Synthmaker archive you'll find a few files dealing with sysex.
I havn't looked at them so I don't know if you'll find what you're after but this could be a good starting point…
The files I've found when searching for "sysex" have the Numbers: 3451, 4015, 4955, 6587, 6594 ...

Yes, it looks like you're right - I discovered this thread on the Reaper forum ; it's quite old, but if you scroll down to the comments by 'Paul Fenton', he describes the same problem with his SynthMaker plugins, and there's a little bit of dicussion about how VST handles SysEx and regular MIDI ...

I have made a test and now I am pretty sure that the problem is in the way in which the VST plugin sends out the sysex messages.
I have used my main VST host, i.e. Cantabile 3 Performer: in Cantabile every midi in and every plugin has a midi in/out monitor.
When I send a sysex message from my Roland ...

Thanks very much, Trog.
I have tested the VST in VSTHost, that is simple, solid and usually manages very well sysex messages.
I’ll try again with some other host before using loopMidi.
I’ll let you know.
Anyway I am very interested whether other FS users have met the same problem or not.
Thanks ...

Dear All,
I am building up a midi VST plugin to control the Roland Integra-7 synth.
Although I have already built up some midi VST plugins, it is my first time with sysex messages and the Integra-7 receives cc messages but, for certain functions, only sysex messages.
I tought to be able to send ...
