Blamsoft has introduced F-16 Filter – a flexible multi-mode filter for iPad.

F-16 Filter offers sixteen modes, frequency and resonance controls, saturation for analog-style soft clipping, and wet/dry mix.

The 4 pole lowpass mode is designed to provide the frequency response of the Moog ladder filter. The other modes provide the choices available in the Oberheim Matrix 12 and Xpander synthesizers.

F-16 Filter is an Audio Unit Extension that works inside host apps. Just open up your favorite host that supports Audio Units and add it as an effect.

In addition to controlling the filter through the knobs and sliders, you can use the frequency response display to control cutoff frequency and resonance simultaneously.

The sixteen filter modes available are:

1, 2, 3, and 4 Pole Lowpass
1, 2, 3, and 4, Pole Highpass
2 and 4 Pole Bandpass
2 Pole Notch
3 Pole Phase
2 Pole Highpass + 1 Pole Lowpass
3 Pole Highpass + 1 Pole Lowpass
2 Pole Notch + 1 Pole Lowpass
3 Pole Phase + 1 Pole Lowpass

F-16 is available in the App Store for US $2.99.
