[sdiy] Frontier Design Tango successfully modified for DC output

[Adam Schabtach]

Recently I modified a Frontier Design Tango (older 20-bit version) ADAT
audio interface for DC output, allowing it to be used with software such as
MOTU's Volta and Expert Sleepers' Silent Way to control analog synthesizers.
It's able to control my VCOs over nearly a nine-octave range so its
performance is much better than the MIDI-CV converter I built awhile ago.
(Somewhat ironically I submitted the artwork for having the PC board
fabricated for that project the day before Volta was announced.) I've posted
step-by-step instructions, with photos, on my website here:
