Well, guys, this is what online forums are all about. We've got there in the end. We may not strictly have increased the sum of human knowledge, but at least a bit of it is more exposed to general view than it was.

I've checked out three options:
1. Martin's suggestion (switch off touch sensitivity via Pref/Channels/Options... -> Boost THRU Velocity by "127") works absolutely. It means the sound is a bit loud as you record, but adjustable (melody or soloist) on playback, and there is no touch sensitivity at all.

2. I noticed that in the same box is another option - a check box for 'Controllers Thru', which is on by default. I did a recording with this box unchecked, and no Thru Velocity Boost.

3. I've also checked out opt>preferences>RecFilter, and unchecked all boxes except 'Notes' (and no change from default in the Pref/Channels/Options settings. )

Both 2 and 3 gave a very hard touch, but not absolutely touch-insensitive. If you hit a note extra hard there was a slight gain, and if you touched more lightly, there was a significant drop in volume, but the touch was hard enough that you didn't get unwanted micro-variations e.g. when making an awkward leap in the fingering. So either of those settings are actually very useful, because in effect they give you 2 or 3 voices off one setting.

But Martin's (1) does absolutely and exactly what I was looking for.

Many thanks to everyone who contributed
