Looking for a Standalone MIDI Note Hold App

[YoddYarmonics]

I like to route things around different software and I've been pretty successful achieving what I wanted until i realised I need a NOTE ON (hold) software (win10) to help me with using some of the vst hosts I use without the need to press any real or virtual Midi keys.

Does anybody here know such a program?

Cheers

If on a PC load up loopmidi https://www.tobias-erichsen.de/software/loopmidi.html

Then bring up any standalone of vsti host and have it send to one of the virtual midi ports
Open your other vst host and have it read from the same virtual midi port.
Then start a midi sequence on the first one.

Why are you so dead set against hardware? If I want really long sustain I use a sustain pedal. Would that not work for you?
