Sound Parameters – Effects

5. Feed the microQ´s audio input with your external signal and trigger one or more notes.
You should hear the vocoder effect. We recommend using speech or drum loops as
external audio material.
6. Try different settings of the vocoder parameter and tune to taste.
First we recommend the use of the vocoder preset patches at the end of bank C in the microQ´s
factory soundset.
Bands 002…025
Sets the number of filter bands. A setting of 25 bands results in a very fine frequency resolution, so
that the original signal is almost completely preserved by the synthesis filters. For a classic sounding
Vocoder effect, you should set the number of bands to values between 13 and 22 bands.
Analysis Signal External/Aux/Inst.1 FX/Inst.2 FX/Inst.3 FX/Inst.4 FX/Main in/Sub1 in/Sub2 in
Determines the source of the signal that is analyzed. This signal is also known as Speech signal. The
synthesis signal always comes from the current sound. This is not a real limitation because the voice
architecture isn't affected at all by the Vocoder. You still have all three oscillators and two filters.
• External means that the source is the audio signal that comes from the External In jack .
• Aux means that the source is the audio signal that comes from the internal Aux bus. Please
refer to the chapter "Multimode" on page 40.
• Inst.1 FX…Inst.4 FX means that the source is the audio signal that comes from the internal FX
bus. Please refer to the chapter "Multimode" on page 40.
• Main in means that the source is the summed audio signal that is routed to the microQ´s
Main Out jack .
• Sub1 In means that the source is the summed audio signal that is routed to the microQ´s Sub
Out 1 jack .
You achieve the best results with external signals when you set Input Gain in the Global Edit
to 1 or 2 for line level signals.
A. Lo Frq and A. Hi Frq 10.9Hz…16.7kHz
Set the frequency of the lowest and highest analysis bands respectively. You should set A. Lo Frq to
around 220Hz and A. Hi Frq to 14kHz for voice analysis (the default values) or to around 100Hz and
16kHz for drum loops or other signals with a lot of bass and treble.
All other analysis bands are spread equally between these two bands.
If you find that the Vocoder isn’t tracking quite right, then you might want to narrow the
frequency range of the analysis bands.
If you want to extract one instrument from a complex sum, you should set Bands to 2 and
change A. Lo Frq and A. Hi Frq until you find the signal’s main frequency range. So you can,
for example, process a full sounding String Pad to be emphasized on the Snare Drum or Hihat
figure of a drum loop.
