Has anyone tried patching it with noise or some fat high harmonic content chords to the input and with no feedback and mixed the output it with the original signal (50/50) and the sweep the frequency? Good jet flanger? Is it good without the original signal mixed in?

Considering a purchase but this would swing it..

considering selling mine. I have a few other physical modeling modules that work better than this. using as a filter, the only time i got anything exciting is when i plugged the 2hp pluck into this and evenloped the resonance.

The Exploring the 2hp range video by modular monthly gives a demo of using as a filter. I havent gotten anything exciting as them though.

Kick drums sound great through the Comb.

How can you coax brass sounds out of this?

I've had some good results when patching a square/saw wave into the 2hp comb filter and then patching that into the fm input of an oscillator and then modulating the parameters in the 2hp comb filter.

So two oscillators plus comb?

Does anyone know if the output from the Comb is just the wet sigal or if it is internally mixed with the original dry signal?

Remorseless modular beat; a bit discordant but melodic too. 🦊🦂

It’s a filter, so the terms do not apply, but if you insist it's always fully wet.

A phasing effect can be produced with an all-pass filter mixed with the original signal. A flanging effect (AKA comb filter) can be produced by mixing a delayed signal with the original. Alternatively Both can use feedback to produce aspects of the effect without the need for the original signal. It’s all about implementation. Hence my question, since the comb effect can be achieved with or without the original signal.

Can anyone who has the module confirm if it exhibits comb filtering with the feedback at zero? If this is the case then it is being mixed with the original signal.
I’m interested in this because if the original signal is absent then it should be possible to mix two comb filters together and produce thru-zero flanging...which would be awesome!

I ended up writing to the 2HP company and they have confirmed that the original signal is always included in the output.

Anybody have examples of this being used for "normal" flanger duties, i.e. LFO to frequency CV?

The frequency control (whether CV or knob) has audibly sized steps, so if you put smooth CV into it you will hear the steps. I don't think that would work well.

Yeah, that sounds useless for the purpose. Too bad.

I considered both the 2HP Comb and also the RS-120.

Then I found an old Digitech RDS1900 rack delay. On the Flange setting it does a delay from 1.5ms to 14ms which can make a nice comb filter when fed-back with the dry signal. It has speed/width LFO knobs for the delay time, and also a VCO Control (CV 0..5v) input on the rear! I have yet to experiment with this but it should be good for Karplus-Strong and comb. On the RDS the time values are continuous not stepped. The LFO does drift slightly after some minutes on my unit.

On the 2HP Freeze there’s a slight lag when setting the size control / CV input, but it’s not a deal breaker. I guess a small microcontroller is doing all the work - audio and sampling control inputs. I imagine the 2HP Comb is a similar design to the Freeze?
