I will try to explain what I do need, and would be great if it will be possible:
I have downloaded some free VST plugins that generates chords and arpeggios [and some makes harmony progressions] but uses only internal MIDI sounds [that my midi keyboard [attached to a laptop] does not have].
Question is: is there any way I can connect standard VST instrument and link it with that VST instrument [it is not VST effect, it is VST instrument] so it can play chords / arps by using my VST I want?
Internal midi means - VST instrument can play with sounds that are built into MIDI keyboard [but not VST instrument itself]. So yes, I suppose - output is plain MIDI signal?
on windows you need a ‘midi loop-back driver’ like LoopBe1, Hubi’s or a “virtual midi-cable”.
for sending the midi back to an input. or you could try to use it inside a vst like bidule or
energyxt and connect it there with a vst instrument.
