If I understand correctly, you want a style that will hold down a single note over many measures; the essential definition of pedal point bass.
Is that correct?
Yes, or a real track that does similar. I don't want a solid "tone" as in tone-generator, but a something that holds the note. I'm trying to generate a track to add to a mix that will take the place of (or be the equivalent of) an organist holding the pedal down.
Sorry I didn't see this earlier.
