Binary Counter

Binary Counter is a simple gate sequencer that uses binary numbers to turn gates on & off.

Starting from zero, every time a gate is received on din, the value of the counter is incremented by k, and CV1-6 are set on/off according to the binary representation of the counter.

I/O Mapping

I/O Usage
din Input gate signal
ain CV input to control k
b1 Change between discrete or continuous modes
b2 Reset n to zero
k1 Control for k
k2 Attenuator for ain
cv1 Least significant bit output
cv2 2s-bit output
cv3 4s-bit output
cv4 8s-bit output
cv5 16s-bit output
cv6 Most significant bit output

In discrete mode (default) all outputs go low when din goes low.

In continuous mode the outputs stay on across consecutive values.

k = 1

Configuration

This program has the following configuration options:

  • USE_GRAY_ENCODING: if true, instead of traditional binary encoding, the pattern is encoded using gray encoding. This means that consecutive gate patterns will always differ by exactly 1 bit.
Decimal value Traditional binary Gray encoding
0 000000 000000
1 000001 000001
2 000010 000011
3 000011 000010
4 000100 000110
5 000101 000111
6 000110 000101
7 000111 000100
... ... ...

To enable Gray encoding, create/edit /config/BinaryCounter.json to contain the following:

{
    "USE_GRAY_ENCODING": true
}
