Ed!son –Instrument Editor

The voice architecture of the WAMI BOX is based on subtractive synthesis.

Audio signal generation

Before you can hear a sound, it has to be generated. As you already know, the

WAMI BOX's instrument sounds are based on wave files. Playing a wave file is

not an art form - the cheapest sound cards will do the job. Things get interesting

when playing a wave file as an instrument voice, in other words in multiple voices

and at any (musically appropriate) pitch.

To put it briefly: Unlike other sound cards, our WAMI BOX has its own onboard

sample RAM which permits the instant reproduction of all of the samples stored

there at any required pitch. And that at up to 64 voices simultaneously!

Ed!son's audio signal generation parameters can be found in the OSC field.

Signal shaping

While the signal generation section described above is playing our sample in the

desired pitch, the signal can be altered and manipulated - or shaped - over a wide

range. This is performed by reducing specific frequency ranges. The frequency

above which these signal components are filtered out can be adjusted and is

Signal shaping
