"Audio + Video by G-Storm Electro c. 2022

Introducing Influx, an audio sub-mixer for eurorack.
A streamlined design taking 16HP.
Six channels having LED mutes, level, and pan.
A stereo input pair having level control.
Stereo mix output.

In this video I'm putting the Influx mixer though it's paces.
I put together an elegant live performance patch using all 3 of my cases.
Be sure to listen on headphones or quality monitors to hear all the sub-bass frequencies.

"Manage the Influx of audio signals in your Eurorack modular system. Influx is a streamlined 8-Channel audio sub-mixer. Suitable for your mixing needs within smaller to medium sized systems. Or chain two Influx units together for larger systems.

6 Mono Input channels each having: Bourns 20mm throw audio level faders w/ 3x gain possible, blue LED latching audio mute button, pan pot, and a scribble strip!

One Stereo Input pair of Left/Right inputs on channels 7/8 - Audio level rotary pot w/ 3x gain possible, Channel 7/(mono) is normalized to both L/R if nothing is plugged into Channel 8/R jack.

For larger systems you can chain two units together for a total of 14-Channels. Simply patch the output pair of one Influx to the 7/8 input of another. A 10-to-16 pin ribbon cable is included. Each module is 142 solder points all crafted by hand in limited quantities, and tested for quality assurance.

Specs:

16HP (80.5mm) Module width
22mm Module depth
21 mA on +12V
9 mA on -12V
5V not used
Influx pairs well with:

Pittsburgh Modular Outs
Befaco Output module v3
GSE DC571 Lo-Fi Dual Compressor
…another Influx mixer for 14-channels"

Some Darkscape Eurorack patches featuring the SH5-VCF.
Exploring some near-oscillation resonance sounds.
And frequency modulation of the VCF which this diode filter is so good at.
This time around using Big Sky Reverb and Timefactor Delay.
If you want to hear the naked filter alone the first two demos I made were bone dry no effects :D

I used different colored patch cables, so maybe you can glean what is going on.
If there are questions about that go ahead and pepper me in the comments.

SH5-VCF is all-analog eurorack adaptation of the Roland SH-5 Synthesizer Filter and Mixer.

As per usual, listening w/ headphones or quality monitors is the best audio experience.
Watch your levels, this is a filter demo w/ some resonance ahead.
Be sure to check out SH5-VCF Demo 02 to see how I made the patches in this video!

"Time to get a little more serious.

SH5-VCF is an all analog Eurorack adaptation of the Roland SH-5 mixer and Dual Filter. There are no filters-on-a-chip here. The SH5-VCF uses all discrete components and quality op-amps to work its special mojo. Like on the original, the Low Pass circuit is comprised of open-collector matched transistor pairs arranged in a diode ladder configuration. The lack of temperature compensation was also respected, so while the resonance can self-oscillate the v/oct keyboard tracking is about 3 octaves at best. This same configuration used in the Roland SH-1000 and the earlier System 100 (not 100m).

The Dual Filters: VCF + BPF
| VCF | The VCF (Voltage Controlled Filter) comprises one HP (High Pass) and one LP (Low Pass) circuit in series. VCF Select switch can choose 1) HP, 2) LP, or 3) BP (Band-Pass) configuration. Due to the unique design, the HP resonance is actually derived by overdriving the LP circuit.
| BPF | The dedicated BPF (Band Pass Filter) has its own discrete circuit distinct and apart from the VCF. The original BPF circuit has been respected, but greatly expanded upon using a proprietary voltage controlled feedback path to enable frequency control via external signals. This feature wasn’t available on the original design. The original did not have a buffered output jack for the BPF neither, as the SH5-VCF does. The BPF Level attenuator will affect the main output only.

The MIXER
There are four audio signal inputs, each with its own fader pot and filter routing switch. Each routing switch can send each audio line to either VCF, BPF, or both VCF + BPF.

The 3 CV MODULATIONS – Choose Wisely
Incoming CV signals can be used to modulate any filter frequency cutoff. Signals can be up to +/- 10Vpp DC polar or AC bi-polar at the inputs.
| CV1 | has inverting and non-inverting behavior where zero is at 12:00.
| CV2 | has non-inverting behavior for both filters, and inverting available to VCF only
| KB | is a non-inverting V/OCT Keyboard Tracking control available to both the VCF and BPF, typically a Keyboard Voltage – but can be any kind of polar or bi-polar signal.

A Eurorack power connection ribbon cable is included. To get the most out of the filter experience follow your filter with a VCA. The filters require startup voltages on the low end to avoid audible thump, so there will be sub-frequency audio seepage. A post-filter VCA (sold separately) is recommended to gate the filter. Be sure to check out the G-Storm Electro 2xVCA when available.
