TIMING INDEX / SECTIONS BELOW Here's the new Filter 8 from Joranalogue. It's a VCA based filter topology similar to but not exactly an OTA design. It features a unique resonance circuit and (according to Joranalogue) is "the cutting edge in analogue VCF design". Now I can't talk specifics about the circuit but feature wise it certainly packs in a massive punch. 8 filter outputs including 1, 2, 3 and 4 pole low pass filters, a 1 pole high pass, unique band boost and notch, phase shifted output and 4 pole band pass. There's gain compensation to even out each output under self oscillation, we can freeze and hold the core of the module to effectively silence and halt the output or freeze (like a sample/track and hold) when it's producing it's own CV signals. The outputs turn to 8 phase shifted sine waves that tracks great as a multi phase oscillator or LFO and patching feedback means we can create a range of saw like waves with various exp. lin. and log. curves. We can drive the filter with the second input, or again with feedback, exponential and linear FM means we can get gorgeous rich formant throaty vocal tones under audio rate modulation or musical harmonious FM tones when using it as an oscillator. There's even more so I'll let the video do the talking. Enjoy and leave a comment to chat below.

TIMING INDEX / SECTIONS

00:00 hello, introduction and patch previews of what's to come

01:17 Feature walkthrough, going through bits of the manual, all the ins outs and controls.

03:26 Filter sweeps, 1, 2, 3 and 4 pole low pass, high pass, band boost and notch, phase shifted out and the band pass. Various resonances and output comparisons.

06:35 Using dual inputs to drive the filter

7:11 Dual inputs driving the filters. Sweeping through the responses.

08:40 Animating the filter. Using envelopes, sequences and gate patterns to modulate 1v/oct, exponential FM and resonance depth.

10:42 Filter rich layered and animated detuned sounds. This also looks at building up dynamic patterns and filter modulation.

13:41 Audio rate modulation of cut off and audio rate modulation of 'hold' for a sample and hold like "freeze". Similar to sync and downsampling FX.

16:28 Driving the filter with feedback. Creating clipping, saturation and non linear responses. At point digitallike phase modulation / phase distortion overtones appear.

20:09 Phase shifter! Using the phase shifted output like a phase shifter effect. There's also audio rate resonance depth modulation in this patch.

21:56 A short acid break. Patching up some 3 pole 18dB per octave low pass patches for a little bit of an acidic filter pattern.

22:48 Filter Pings. Using the ping input to excite the filter core. Create melodic lines, deep bass, percussion and linear FM tones.

25:42 8 phase oscillator. Using the oscillating filter as a sine oscillator. Glassy and harmonious FM tones under modulation.

27:20 Patching feedback over the oscillating sine to create new wave shapes. You can make a near perfect saw wave as well as other exponential and logarithmic ramp shapes as well as some odd comb like shapes.

28:19 8 phase voltage controlled LFO. Using multiple phases to create cascading modulation across a wider patch. As above with audio we look at feedback to make new LFO shapes too.

30:22 Slew limiting. As the filter works at sub audio rates we can use it slew a signal. Here we add glide by slewing a pitch sequence. We also add resonance for a way to inject wobble and vibrato into the pattern.

32:39 FM oscillator tones a little musical break. We look at gated the hold on and off while this operates as an oscillator. This creates little clicky rhythms and breaks in the sequences we're using.

33:52 Resonating envelopes using envelopes to excite the near oscillating core of the filter to create wobbles within the envelopes shape. We can also superimpose audio rate tones or LFOs into the envelopes too.
