Stages

toneburst · 2018-08-03T10:57:18.186Z

Had a bit of a play with Stages as an envelope generator and clocked LFO the other day.

Stages is generating pitch and amplitude (Decay) envelopes for the kick, triggered by Grids.

Sound source for the kick is Ripples, initially with white noise from Kinks, then I turn the resonance up until the filter begins to self-oscillate. Cutoff frequency modulated by Stages Decay envelope.

Veils is the VCA for the kick.

I had fun messing with the decay shapes for the pitch and VCA envelopes on Stages.

Stages also provides another Decay envelope, triggered at the same time as the kick, which envelopes the same Kinks white noise source, which is then passed through Shelves, modulated by Stages clocked LFO, with another Veils channel as VCA.

Plaits on hat/snare noise, triggered by the 2nd Grids channel and modulated by another clocked LFO from Stages.

Braids through Clouds on nasty drone, with a couple of Clouds parameters modulated by clocked Stages LFOs.

Dervish on reverb, and Streams squashing everything.

As usual, minimal musical content, and way too long.

You can mix STEP and HOLD stages to create steps that are either clocked or that lasts for an adjustable duration.

Just ordered a Stages to add to my “Mutable” rack; which now consists of: Elements, Clouds, Marbles, Kinks, Stages plus a Malekko Heavy Industries AD/LFO and a Doepfer ‘Source of Uncertainty’. Apart from integrating it into my ‘rhythm section’ (2 x Grids, Qu-bit Rhythm, 3 x TRL Stepper Acid, 2u Div, Doepfer multiples and clock divider/sequencer) it also works well as a standalone unit for creating sound by itself with little or no input from me.

Planning to do a long performance with it once the Stages arrives, where my only input will be to press Start . . . (and Stop at some point)

I apologize if this might be a bit of an annoying question, but how difficult would it be for someone (such as myself) with little to no coding experience be to adjust the firmware such that the ranges of the LFO’s are shifted more towards the very slow? I love very slow cycles but with the default firmware I have to use a negative offset to achieve this so it would be nice to just have slower cycles built into the module to free up my utilities.

  out[i].phase = ramp[i];
}
ShapeLFO(parameters_[0].secondary, out, size);
active_segment_ = out[size - 1].segment;
}


void SegmentGenerator::ProcessFreeRunningLFO(
  const GateFlags* gate_flags, SegmentGenerator::Output* out, size_t size) {
float f = 96.0f * (parameters_[0].primary - 0.5f);
CONSTRAIN(f, -128.0f, 127.0f);
const float frequency = SemitonesToRatio(f) * 2.0439497f / kSampleRate;


active_segment_ = 0;
for (size_t i = 0; i < size; ++i) {
  phase_ += frequency;
  if (phase_ >= 1.0f) {
    phase_ -= 1.0f;
  }
  out[i].phase = phase_;
}
ShapeLFO(parameters_[0].secondary, out, size);

Something like this:

const float frequency = SemitonesToRatio(f) * 2.0439497f / kSampleRate * 0.125f;

PSA Olivier is the best and it was really fun learning how to edit firmware for the first time today.

Here is a firmware wav file implementing the above change for slower LFO’s!

As with all firmware, be wary of actually playing the file lest your ears be destroyed.

Cool easter egg - made me laugh

Markthom · 2018-11-12T23:19:32.327Z

It’s awesome, and I thought Easter Eggs were not happening - I need another Stages now!

forestcaver · 2018-11-12T23:27:16.290Z

One stages just gets lonely - it needs company

bloc · 2018-11-13T08:01:59.674Z

So what is the easter egg?

forestcaver · 2018-11-13T09:19:53.483Z

I’m new here so not sure what the ethics on revealing easter eggs is, but with two stages you now have a complete voice (only one needed for the easter egg and it’s awesome).

If wiser heads give the nod I’ll drop some hints… or just say it!

buzzard · 2018-11-13T19:22:38.058Z

I thought the rule was once you figure it out share the knowledge…but maybe I just remember the world as I want instead of how it might be

forestcaver · 2018-11-13T19:25:51.583Z

Ah, ok - ever wondered why the chaining cable is so long for just one module ? It only needs to jumper to the next module - right beside it - right?

On its own, stages gets hungry - like ouroboros…

Harmonic oscillator awaits…

Robrecht · 2018-11-13T19:30:19.544Z

I was intrigued by that Ouroboros reference in the code and yet never made that, eh, connection. Oh wow!

Markthom · 2018-11-13T20:07:11.818Z

I’ve got a video of the Easter Egg just uploading Currently at 39% …

forestcaver · 2018-11-13T20:07:14.131Z

It’s rather cool… worth the price of the module, if it did nothing else… it’s a really nice ui for it as well…

buzzard · 2018-11-13T20:07:40.890Z

I was just searching YT to try and find something.

forestcaver · 2018-11-13T20:07:57.654Z

Fast work Mark ! Did you get home early ?

Markthom · 2018-11-13T20:08:12.395Z

It’s VERY cool - lots of potential and I will need to buy another Stages as a result!

forestcaver · 2018-11-13T20:08:37.212Z

With two of them you have a complete voice…
