Meet the Bit-100 v2’s Filter
Whilst the Bit 100’s filter may appear mundane to those familiar with synthesis, it can really deliver,
especially when controlled by the Bit 100’s snappy envelopes. It’s a crucial contributor to the distinctive
character of the Bit100, being loosely based SEM 3388 filter chips.
If you are not already familiar with synthesis, I have provided a brief introduction to the subject of filters in
Appendix #2.
This section assumes knowledge of synthesizer filters and focuses on issues pertinent to the Bit 100 v2.
The instrument features a single low pass filter (per voice).

CUT CUT-OFF FREQUENCY (1)
- sets the cut-off frequency of the filter.
RES RESONANCE (2)
- sets the resonance amount.
ENV ENVELOPE AMOUNT (3)
- The Bit 100 v2 features an envelope generator specifically for use with the filter; its parameters
are embeded in the filter section of the parameter map.
Envelopes are discussed in detail later, so we won’t go there now, but parameters (6-9) control
the following envelope attributes:
A - Attack D - Decay S - Sustain R - Release.
The parameter (10), labelled A controls velocity data to attack time.
With this set above zero, a harder strike produces a quicker attack, relative to the overall
attack setting (6).
CAUTION: Turning up the resonance can lead to a profound increase in
sound volume, perhaps unexpectedly. Please consider both your speakers
and your ears and use this feature cautiously.
