Or is it hiding on my keyboard somewhere

I need it to calbrate a monitor/sub setup.

From my calcs - there is A at 110 and at 55Hz so somwhere in between, maybe a E0 or F0?

Take a modular patch, insert a ConstFreq and an Osc.

You could create one in soundforge. Menu: Tools\Synthesis\Simple. Then set freq, should do the trick. If you have soundforge that is.

Allternatively arela, use ControlRoom - type 85 into the sine test tones box, voila!

This got me playing with ControlRoom this morning - discovered my little room has huge standing wave at 111 hz . Wondered where it was

I just got the last xlr connectors -

. Only 3 connectors left to solder, then...
I bought xlr male, should be female - no sub jet

Just in the hope I understood what you're looking for.

I'm not sure MIDI note numbers are correct. If not, do advertise me and i''ll 'update' my sheets. If anyone would add MIDI notes sequential numbers, or tell me which is the correspondence I'll be very thankful.
Millisec values represent single wave cycle durations.

Sorry, you should shift the three columns of calculations some row down in the Xls, then copy and past up twice the values of the first row to obtain 55 Hz.
(Similar thing can be done with upper notes).

It should be A0.

Frequency doubles each octave...

=Added=

However, even using semitone cent tuning, the closer value is 85,018 Hz (F - 46 cent or E + 54 cent ).

But table and calculation sheet might be otherwise useful

Thanks Cochise, this is useful.
I generated a 85Hz signal with Audition1.5.

Easy to get confused with this stuff, because a bass generated with Band in the Box is often to low to use without transpose up one octave.

And i always forget witch A is 440

More good news, after some seriouse investigation, i found i had the right XLR connectors. The manual is fooling me for the second time

Connect the signal cables from your source to the female XLR IN connectors on the ...

That is you need a male XLR on your cable - logic?
Yes, in fact, and after failure

me too, and the 3 octave plus octave shift possibility for a total of 6 octaves also doesn't help really

yes, of course
