  4. Wrestling with routing midi and audio simultaneously to one plugin

  • Wrestling with routing midi and audio simultaneously to one plugin

    I'm sure I must be missing the obvious, but I cannot get both midi and audio to hit a given plugin. In this case, the synth produces both its own audio and can process external audio. I can get the routing working in both Cubase and Cantabile with the plugin hosted locally.  VEP gives me the option to run as an instrument, denying audio input, or as FX, denying midi.
    What have I missed?

    TIA

    the instrument channel is not built to input audio at all.

    you have to instantiate whatever it is as an effect.

    the effect instance does not deny MIDI per se, but it is not made to enter note-ons particularly

    I have definitely controlled an effect via MIDI CC in the piano roll, same channel is a limitation unless you use channel = All, having dedicated one port to it. should work, unlike the above I have not done

    Thanks for your response @civilization 3.
    I understand that parameter control via CCs is catered for in FX channels but, as you point out, note events are not.
    Whether this is because such a requirement wasn't anticipated, or whether it's a technical limitation, I don't know.
    In my particular scenario, an instrument like Cherry Audio's Voltage Modular which also processes incoming audio, can stress a CPU at low latency when it's loaded with modules. If there were a way to comprehensively handle both midi and audio at a VEP channel, it would be useful.

    Cheers!

    Particular DAWs also have the limitation; eg., REAPER does not, it does not make the distinction effect to instrument channel. I don't use it but this is a selling point for fans of it.

    In Cubase an effect may be approached to effect this by a kind of back door using VST3 sidechain input if the plugin has that. I saw someone trying it in Studio One to no avail with a granular effect which can use note-ons but the version of it was not VST3, for instance, it's identical to Cubase's handling.

    Hi,
    Cubase doesn't necessarily require VST3 to achieve this. A plug in inserted, say, into a Group channel processes the audio, of course, while a Cubase midi track has the ability to address that Group channel, with the full compliment of midi data. Very easy.

    I stand corrected! thank you, I never saw that before
