Subject: Re: dirty ole' progger buttons/joystick progger on EX800?

thanks for infos, lol, especially the breakpoint slope
business. (just having trouble visualizing it)
i'll be ∗very∗ careful approaching those button covers..
impossible to find if damaged!!
are these going to be 'tact' switches? (let's have a look...)

btw, as i read in the manual that the joystick on the keyboard
version can be used for parameter editing, what's the option
for us EX800 rack owners? there's plenty of space on that panel
to fit some kind of joystick device. has anybody done this?
would do away with need for rotary encoders etc. was thinking
that a playstation-type xy stick could be neat and unobtrusive,
but not sure the action would be correct, as it is sprung. it
also has a down-click function, which could be used as an additional
write button(?just an idle thought...).

i found, in previous use in a rack, that the main drawback of the
unit was that you tended not to want to go editing patches when you
were 'in the flow' of things, and i'd go to the juno106 i had at the
time for that instead. what i mean is that my main interest in parameter access is in tweaking a voice quickly, within a mix, as
opposed to loads of realtime controllerisms,(although that's nice to
have too).i'm going to try to find those demos Mike did using
realtime controllers, but if (you) have any new ones, using say a
Novation Remote, please link us up! i'm really not sure about sending
NRPNs even now, and have never done it successfully. Last time i
tried was using an atari, and trying to build a mixermap that could
do it. something wasn't done right and i stuck with sysex. (and of
course, that means i'm accustomed to the idea of sending controller data offset from note-on/offs)
