Looking for a standalone MIDI Envelope/LFO tool (Windows)


I’m going to be operating some live visuals on a gig next week. I’m using the OP-1 as midi controller, however I want to make a few ultra fast sweeps and wiggles on the control parameter that would be to fast to do by turning the knobs.

So I thought I’d give it a shot to ask you folks if you know about any cool tools that I can hook up inbetween and trigger envelopes or LFOs to send a MIDI signal to Resolume (VJ Tool).

Preferable something that is cheap or free and doesn’t use up too much CPU power.
