1 PHILOSOPHY AND DESIGN
FUMANA is a dual all-analog fixed filter bank. Each
filter bank is composed of an array of 16 independent
bandpass filters tuned to specific frequencies.
FUMANA is designed around one basic core principle:
modify the spectral content of the incoming audio signal
by filtering it through 16 bandpass filters in parallel and
then vary the amplitude of each resulting band.
Even though this core principle is relatively simple, the
key feature of FUMANA is that it provides a wide set of
controls over the bands’ amplitude: the spectral content
of the incoming sound can be thus modified by the faders,
which are individually CV-controllable; by the envelope
followers which are generated by the analysis of the sound
patched in the Modulation input; by the global paramet-
ric controls such as Tilt and Scan.
Furthermore, a flexible input/output signal routing al-
lows the musician to “split” the 16 filters into two 8-band
spectral processors by grouping the odd and even bands
separately. It will be possible to process two independent
signals, or to blend two signals into one output, or even
to perform two different sonic treatments over the same
signal and route it to two different output sections.
Individual outputs are available for each band, both for
the Main sound (i.e. the filtered one) and for the Mod
sound (i.e. the resulting envelopes).
Since a spectral transfer tool may be used as a “vocoder-
like-effect”, the FUMANA provides an input for an
