- Manually controls the filter's cutoff frequency.
- Frequency Level
- Allows inversion and attenuation of the cutoff frequency control input.
- Manual control of the filter's resonance.
- Resonance Level
- Allows inversion and attenuation of the resonance control input.
- Signal Input 2 Level
- Allows attenuation of the adjustable input signal.
- Frequency CV Input
- Voltage control of the filter's cutoff frequency.
- 1 V/Oct Frequency CV Input
- Voltage control of the filter's cutoff frequency at a fixed 1V/Octave. Normally used to track the keyboard.
- Resonance CV Input
- Voltage control of the filter's resonance.
- Signal Input
- Signal Input at full amplitude.
- Signal Input 2
- Signal Input which is adjustable with the level control.
- High Pass Output
- Filtered output signal where low frequencies are attenuated.
- Band Pass Output
- Filtered output signal where a frequencies on either side of a narrow band are attenuated.
- Notch Output
- Filtered output signal where a frequencies in a narrow band are attenuated (Band Reject).
- Low Pass Output
- Filtered output signal where high frequencies are attenuated.
The Q107 Filter changes the harmonic content of signals to create new, interesting sounds. This removal of harmonics is the basis of subtractive synthesis. Both the cutoff frequency and the resonance (Q) of the filter can be controlled manually and/or controlled by another signal such as an envelope generator, oscillator, keyboard, etc. Control signals can be attenuated and inverted. Low Pass, Band Pass, Notch (Band Reject), and High Pass responses are provided simultaneously.
12dB/oct Low/Band/High Pass and 6dB/oct Notch modes
Use the Q162 Filter Mixer next to your Q107 Filter to easily create new sounds. Simply select the amount of High Pass, Band Pass, Notch, and Low Pass response used to contribute to the final waveform which is available at 2 connectors.
The Q162 is connected to the Q107 Filter using cables behind the panels. Requires exchanging connectors on the Q107 filter. Soldering not required.
