BF35

Compact Bass Filter (LPVCF,VCA,Envelope)

BF35 is the ultra compact tone shaping module that includes lowpass VCF and VCA with an unique decay envelope generator.
A simple synth voice can be constructed by just adding a oscillator module.

This VCF and VCA are inspired by MS-10, and it is sensitive to the input level.
The higher the input level, the lower the resonance (vice versa).

This decay envelope generator is also unique, it is sensitive to the gate level and length.
The higher the gate level, the louder and brighter the sound.
And the longer the gate length, the longer the decay time.

control:

• TONE
  • VCF Cutoff Frequency
• DECAY
  • Decay time for VCF(cutoff)&VCA(level)

In addition to TONE and DECAY, you can change the following parameters on the back of the module:

• TONE ENV
  • VCF Envelope Depth
• PEAK
  • Resonance Level
• VCA (ON/OFF)
  • VCA enable/disable switch
• DRIVE
  • Output Overdrive level

input:

• GATE
  • Gate input
• IN
  • Audio signal input

output:

• OUT
  • Audio signal output
