OK - there's no need for emailing song attachments!
THERE IS A WAY OF INPUTTING THESE INTERMEDIATE VALUES WITHOUT LOGIC CONTROL!
Many thanks to "jbmix" on the Sonikmatter site for discovering the following amazing tip:
"I just discovered that it IS possible, after all, to get 0.1dB increments using the mouse. For instance, I just wrote automation data in 0.1dB increments for the volume parameter by putting the automation mode in Latch, putting Logic in play, and adjusting with the mouse not on the fader, but on the yellow numerical readout under the Volume parameter label. It works. In fact the resolution is even better than 0.1dB.. by moving the mouse very slowly, I was able to get 10 nodes between 0.0 and +0.1. Interesting thing though is that when inspecting those nodes in the Automation Event window, between 0.0 and +0.1 all 10 nodes have the very same value = 90."
The trick now is to find a practical way of manipulating this data - I'm working on that now. It all appears in the Automation Folder as jb describes.
