Kickstarter! - Eurorack Infernal Noise Machine in development

Post by flight » Wed Jul 22, 2020 1:24 am

Kickstarter goes live September 24th!
Hey all! We're doing a Kickstarter campaign to fund the productio run and it goes live tomorrow! The first 50 INM-E will have the now-discontinued-by-the-manufacturer large-size joysticks, same as the ones on the Choices module, then the rest will be a smaller version form the same manufacturer. I only have enough stock for the fifty units, then they'll be gone forever. :cry:
If you're one of the first 13 backers to pledge $666.00 for an Infernal Noise Machine, you will also get a RAISE HELL t-shirt and your name in the PCB silkscreen on the back of the module as thanks for helping start this off!

>Kickstarter page here.<

Hey all. Things are far enough along to start a thread about the upcoming eurorack Infernal Noise Machine. I'll get some specs posted soonish but, for those that don't follow @flightofharmony on twitter or our youtube channel, here's a video of me testing out the added LFO. It is all self-patched, no external sources.



<EDIT 9/14/2020> New video!
And here's a video by HEWHOWANTSJEANS showing a song they made with full patch breakdown. Thank you for doing this!


<EDIT 8/24/2020> Now with system summary!
Type
  • Sound source/Oscillator
  • CV & Signal processor
Format
  • Eurorack
Width
  • 48hp/243mm/9.6"
Power
  • 16-pin (2x8) Doepfer standard eurorack shrouded header
  • User-selectable +5V supply
    • System bus
    • Onboard regulated supply
Included
  • (1) Module
  • (1) 9" 16-pin to 10-pin & 16-pin power cable
  • (4) M3x6 mounting screws
  • (4) nylon washers
  • (1) user manual
Functional Features
  • IMP noise core audio source, generated by a nonlinear heterodyning of a pair of oscillators. The IMP has eight frequency regions (Domains) of operation, from semi-random sub-audio impulses to above audio range, used as the primary frequency modulation (FM) source for the VCO. The output is also available to each signal chain as well as an independent output jack.
    Frequency of oscillation is controlled by Coarse and Fine joysticks with multiple Control Voltage (CV) inputs and other controls. The joysticks have breaking Input jacks for controlling external signals, and non-breaking output jacks to allow the signal to be used externally as well as control the IMP.
  • Voltage-Controlled Oscillator (VCO) with Square, Ramp, Saw, Triangle, and Sine, waveforms available to each signal chain along with independent output jacks for each waveform. The VCO has two user-selectable ranges, 1 Volt per Octave (1V/Oct) covering ~4Hz to above 20kHz and Low-Frequency Oscillator (LFO) covering ~400Hz down to ~0.06Hz (~16 seconds per cycle) (more specific range specs will be posted later).
    The VCO can be modulated by the internal IMP noise core or by external modulation sources, and the modulation amount (depth) of either can be controlled by dial and CV.
  • 2 Audio signal chains consisting of a Voltage-Controlled Filter (VCF) (bypassable) and a Voltage-controlled Amplifier (VCA), each with breaking inputs and outputs (I/O). These I/O allow the VCF and VCA to be used independently or can be used as Inserts to the signal chain to allow external effects to be added. The two VCA outputs can also be used to provide stereo imaging and effects.
    The VCF are Voltage-Controlled Bandpass Filters (VCBPF). Filter band width and Gain are varied by the Gain control and the filter's Center Frequency is varied by the fc control and can also be voltage-controlled.
    The VCF In/Out bypass switches remove the filters from the signal chain to pass the raw modulated VCO signal to the VCA.
    The VCA have ±5V "soft-knee" output limiting protection for external modules. Instead of hard clipping, which squares-off the peaks of the signal, the soft-knee performs a gradual limiting of the signal as it approaches ±5V.
  • Summed output of VCA 1 & VCA 2 available at the All Out jack, via the Volume control.
Design Features
  • Lifetime warranty against defects in assembly.
  • Components on one side of PCB for easier serviceability.
  • Modular build to allow simpler repair or replacement of hardware.
  • All trimming potentiometers accessible without disassembly.
  • Pin-to-signal identification on PCB silkscreen to aid servicing.
  • No electrolytic capacitors in signal path or power circuitry.

Sadly, those joysticks are now officially pure Unobtanium. The manufacturer recently discontinued them and I only have enough for the initial run of these. Afterward, the INM and Choices will be using a smaller variant.

That is also in the planning stages. There are a few logistics to figure out, since the original desktop INM had 9 jacks (1/4") but this new version has 34. I might need a bigger box...

So tempting. I already have a desktop INM, but all those additional jacks and the extra domains...(drool).

I'm very pleased about the added jacks - namely all the VCO outputs. You can self-patch this into weird, sweet oblivion.

Update: I figured I'd try a Kickstarter to fund production this time around. I submitted it for review Friday and should hopefully get approval by Wednesday the 23rd, then hopefully launch the campaign Thursday the 24th. I'll post another update here when it goes live.
