Long answer: you could create a sound-font of your particular JV patch and load that in one of the soundfont players.
The Roland JV plugin is proprietary and it’s extremely unlikely that they would port it to LV2 and the MOD platform.
Even if possible it would probably not perform well at all anyway.
ps; you don’t have to ask the admins, other users can also help you with your questions.
thank you for this answer… I know its illegal to capture a plugin, but aside from that, is it possible? So yes it would be but I have to do it myself, as per you answer hehe Thank you so much
If you have Ableton Live Suite, you can load your VST there, use Resampler Pro m4l device for autosampling by recording your VST sound patch audio output per-note/per-velocity and generate a sample pack.
With this samplepack it should be possible to make a soundfount with Polyphone. (beware, it might be a lot of work)
Other DAWs might have something for autosampling also, but I have no knowledge to share on that, except of this feature mentioned to be available at Logic Pro and Mainstage.
P.S. Autosampling means that some kind of automation throws notes one by one to your synth or vst, and captures sound for each note in a separate file. It can also capture different velocity values.
For sure it means that you do not have a full copy of VST, but only a slice of it, one preconfigured patch/preset sounds , but still might worth it if you have one single sound snapshot you really like to migrate into the box.
I am no lawyer, but I see nothing illegal in this, actually.
