One Synth Challenge #85: Xhip (J.Ruegg wins!)

[7angram]

@ aciddose ...wow, many thanks for your detailed response It will take some time for me to go through your answers with the synth in front of me, and digest it all. I really appreciate you taking the time to type all that up! I am sure this will also be very useful for other OSC-ers...

Download link takes me to page with spinal tap video saying "give me some money". .

Does this mean that xhip makers do not want us to do this?

It's a joke about HTTP error #402 "Payment Required".

In reality that wasn't the error but the error it actually prints was generated, probably 401 (Unauthorized) or 403 (Forbidden). Something about the caching configuration I have isn't right.

Example: http://xhip.net/temp/ (will always generate 403)

Solution: hit refresh.

By the time... Our dear friend Antti gets this reply.... He's already done with his track of this month.

Salutes to my friend...!

I can not stress about making songs. But I like making them.

So I do what I do.. Fast.. I leave making masterpieces to you other guys..

Antti, I am planning to be on on your path...now. I am not sure how much I'll be successful, though.

I don't understand how patch #74 'Simple Kick' works.
Both OSC are set to "-" , I presume this means disabled and also noise is turned off, still there's sound ...

Probably filter resonance. I've created my kick the same way, no oscillators, just filter sweep. Only way to get a sine wave out of this synth.

100%! I am definitely going to dig into the waveshaper and drum mode after reading that.

What does "Const Attack" do? I can't see/hear any effect.

PS: Tip of the day: The get a sinus tone put the oscillator to Triangle and Width to 100 or -100.

FMOD and QMOD: What is the source for the cutoff/Q modulation?

Const attack adjusts the attack time such that regardless of the level they start from (with voice recycling), multiple voices triggered at the same time will always enter the decay stage at exactly the same time

FMOD and QMOD: What is the source for the cutoff/Q modulation?

The input to the filter, that is the output from the mixer.

In a modular synth you'd have a cable going to the filter "input". It would also have a "frequency" input and "feedback/resonance/Q" input.

The Fmod and Qmod are the same as if you'd connected the same cable to the signal input as the frequency/resonance.

An example of this effect occurs naturally in the MS-20 with the KORG35 filter. Any signal input to the filter also modulates the cutoff and resonance slightly. (Similar to 10% Fmod and 50% Qmod).

[Mutant]

Wait so it is Frequency and Resonance Modulation and not Modification ?
Then i have no idea how it works.
I always thought these 2 knobs were just there to fine tune the characteristics of the filter (like its response curve) and resonance...
Like on some virtual synths these 2 parameters would be hidden and instead there would be a dropdown menu to choose for example a "moog filter", or a "cs-80 filter", which would set these hidden parameters to some predefined values...

OK, now i reloaded the page and read the rest of your post and it is clear.

The source signal is created by the filter's "trigger" mode. In this case it is set to input a single impulse or spike when the note-on occurs.

The important thing about it is this doesn't go into the signal input itself. Instead it is used to directly set the phase of the filter. This isn't possible in the same way in an analog synthesizer.

There are two stages in a KHN filter. The first stage is "band" and the second is "low". Stage1 is set to the value of the trigger (1 or 0) and stage2 is set to "something else"... in 7 I'm not sure exactly, it may not be set at all or may be set to 0.

Wordy explanation:
The output at low will be a low-pass filtered version of the impulse.
The band output will have the impulse directly as it was input.
The high output will have the difference between the band and low outputs.
The notch output will combine the high and low outputs.

Important part:

Low = low / high-cut.
Band = direct.
High = semi-direct.

Say you want an oscillation immediately without a "pop" at the beginning. Use the low-pass mode with trigger enabled.

If you want a "pop", use the band-pass mode.

If you want to pass the high-frequency content from the input along with a "half pop", use the high-pass mode.

If you're nuttier than a squirrel use notch.

(I have nothing against squirrels.)

Just tested the F/QMOD knobs with an oscilloscope and now i know everything.
It is best visible on low frequency square wave with its width slowly modulated - for example it is possible to make the filter resonate only at the stage of the width you want.
Very cool.

And now i have a Deja Vu, i think i knew it in the past, but forgot.

[rghvdberg]

Thanks @aciddose for the detailed explanation.
I now understand it's all done with magic and sorcery!
