Listen to you! All ready to hack into it!!! :)
The first issue is developing the code to add the feature. Not only do I
have to modify things to make the feature work, but I also have to test
everything else again to make sure nothing breaks. I already slipped a bug
out as was documented earlier last month. People are sending units back for
upgrades, but it costs me money, and time, and it costs everyone else money
and time.
The other problem isn't that I "have" to update, but I'll be requested to
update.
Te third problem is that the more I add, the less intuitive it becomes.
Right now the front panel is WYSIWYG with only one exception. (the level for
stage 8 in GATED STEP mode is actually controlled by the TIME8 knob.) If I
add the option you describe, where am I going to put it? Most likely in the
SLOPE switch, since it's not used in this mode anyway. Well, now there would
be this function that isn't at all obvious. Also, since the TRIGGER OUT is
5mS, it would limit the maximum clock rate of the module, because if you
clocked the module up at 1500Hz, the TRIG OUT would always be on.
This wouldn't be useful in GATED STEP mode anyway. You already have an
incoming "clock" for each stage. In the other modes, all the switches are
used, so it couldn't be implemented anyway.
