Subject: SOST Flanger panel discussion

From: Scott Juskiw <scott@...>

I don't have the PCBs yet but I'm already working out some of the
details for this module. Bill and Will already have a panel proposed
for this (search for "flanger" on this page):

which I like, but there are some options to consider.

1. You don't need a rotary switch for LFO MODE. You can use one of
those 3 position centre-off switches. This frees up pot space for a 1V/
Oct tweak pot (this is shown as an option in the schematics). JH has
mentioned (on an electro-music forum) that the 1V/Oct tracking is not
so good, so having a front panel pot may be a good idea.
2. Can add a jack for LFO OUT (will likely need to add a buffer as
well). This would be post-LFO MODE switch, so the output will be
either ramp, slewed square, or S&H depending on LFO MODE setting.
3. There is a BPOL (bounce polarity) switch on the schematic. Hmmm,
first one who builds one of these will have to let us know if it's
worth implementing or not.

I'm still trying to figure out how best to hook up the LED. Should it
indicate the LFO (i.e. post-LFO MODE switch) or the total delay time?
This doesn't change the panel layout. I'll need to try out different
things after I get the boards in.
