Transistor Ladder Filter
The transistor ladder type filters, which were used in modular synthesizers, a famous masterpiece of the past, are configured in series as low-pass and high-pass filters.
There are two sets of these in this one unit.
Each filter can be turned on/off independently.
When all of them are OFF (BYPASS), the signal passes through the internal wiring only, so the original sound is not affected.
CV Input
The cutoff frequency of each filter can be controlled by the CV signal input to the "CV INPUT" terminal.
Resonance cannot be controlled by CV signals.
Attenuation Slope
The filter slope can be selected from -6dB/oct. and -24dB/oct.
By focusing on these two things, you will be able to quickly bring your ideas to life.
The tonal changes that are unique to this transistor ladder type are easy to understand and easy to use.
