Alesis Andromeda A6

The A6 expression pedal jack is TRS, as is the F2 input.  The voltage being
attenuated through the pot in the F2 comes from the A6 and returns to it via
the same plug.

 

The selector switch on the F2 is for choosing its operational mode, either
using a TRS cable, as you would with the A6 expression jack, or as a volume
pedal inline between the output of something and an amp.  

 

There's no such thing as a mono exp. pedal input, per se.  You'd need to
have a voltage source.  You can use an expression pedal in a modular by, for
instance, taking a voltage source like the Doepfer A176 and running it
through the pedal in volume pedal mode and into a CV in elsewhere on the
modular.

 

FWIW the scaling of the F2 works fine with my CME UF8 MIDI controller
keyboard.  Why Alesis doesn't subscribe the A6 to the same standards that
other expression inputs use is an open question.

Hi Russ,
 
Yeah you can make a cable with the ring floating, or just cut the ring cable
off of a y cable, it serves the same purpose.  I just keep it a y cable and
there it is.
 
I think any pedal will work but it is easier if it just has a jack on it
rather than an integrated cable, although I guess you could cut the plug off
and wire in a mono one with no ring wire connection.  
 
I'm curious about the report that the Alesis F2 has a weird usable range
with the A6, how was it connected?  the exp output is a balanced jack, but
it has some kind of selector switch which might do this in addition to just
inverting the response or something like that.  
 
Anyone with an F2 want to report if the manual states how to use it with a
mono exp. pedal input?
 
the FV-500 is cast aluminum, nice weight to it, big with adjustable pedal
feel and stereo volume pedal control as well.  I quite like it, although I
wouldn't have done it if they hadn't dropped it to $65 from $159.
 
I think any pedal can be used just the right cable needs to be made or
adapted.  The FV-50 looks like it has an integrated cable though.  the
FV-300 looks pretty good in that it has a jack as well.

Eduardo,

Thanks for the input!

Sounds like, in lieu of an insert cable, making up a cable with a TRS 
plug
on one end and a mono plug on the other end, with the tip of the mono 
connected
to the tip of the TRS, and the ground of each connected together 
would do the trick.

My guess as to why just using a mono cable doesn't work is the sleeve 
one the mono
plug shorts the sleeve and ring together when plugged into the 
pedal's jack.

I wonder if the FV-50 will work, as well... it'a a little cheaper 
than the FV-500. Though, I have
to say --- the FV-500 looks a lot more sturdy. Is it metal?

Thanks!

Russ
