Crowdsourced Mindmap: Synthesizers with Comb Filters

Synthesizers_with_Comb_Filters

I love comb filters! Buying a Waldorf Blofeld a few years back caused me to start using them even more because it’s interactive display allowed me to visualize the shape of the filter and correlate that with an audio result. Waldorf Largo and Tone2’s ElectraX also offer this feature.

What is a Comb Filter?

I like the definition on p. 49 of the Waldorf Blofeld Manual:

A Comb filter is basically a very short delay that can be controlled in length and feedback. The delay time is so short that you can’t hear its individual taps but a colorization of the original signal created by peaks or holes in the frequency spectrum. The frequency of the colorization is set by the delay length, which is controlled in the Blofeld through Cutoff, while the amount of colorization is set by the Comb filter feedback, which is controlled in the Blofeld by Resonance.

To further illustrate this, I’ve included a screenshot below which has the same filter type in Waldorf Largo, but with VERY different shapes simply  y changing cutoff and resonance.

Stay tuned for a future article on this with some video.

Crowdsourced Mindmap of Synths with Comb Filters

 A week or so back I was curious how many synths in my rig had comb filters and started to document them in a mindmap. I decided to take things a step further and crowdsource this on Twitter and Facebook and make an even more comprehensive map. The map is constrained to just synthesizers with comb filters that are in production. It also doesn’t contain FX plug-ins or processors that have combs.

What’s New with Tone2 ElectraX Synthesizer 1.2 Update

image

My go to synth ElectraX just got even better with a beefy update that is free for registered users. If you are not familiar with ElectraX checkout this post Modulate This Exclusive: First Look at Tone2's New ElectraX Virtual Synth. Also, checkout this official video overview that was release after my review.

What’s New in 1.2

Rather than simply list the additions, changes, and fixes in a list, I took the time to create a mindmap and group and color code features so you can quickly wrap your mind around this update.

SNAGHTMLacb78cf

Tone2 has a history of creating soundsets that really take advantage of the vast features of their awesome synths such as ElectraX. Their latest soundset is “The Vintage Soundset” which goes fro $49 and I'm sure is no exception.

Vintage is an inspiring collection of 220 patches for ElectraX programmed by a team of professional sound designers.

With its oldschool synth sounds, phat basses, expressive pads, multi-layered sequences and dark atmospheres Vintage is packed with a rich blend of classic sounds, delivering the complete range from analog to digital with a fresh twist.

Vintage is suitable for Electronic, Pop, Techno, House, Soundtrack, Dance, IDM and a wide variety of other music genres.

ElectraX Tips: Importing Sample Data, Creating Vocoder Patches, Creating Your Own Wavetables, and Saving Patches with Sample Data

I’ve started doing some sample-based sound design work in ElectraX. I’ve found a few handy convenience menus and templates that will save you some time.

Quick Import Sample

image

First off, there is a quick import option if you want to use a sample as an oscillator source. Click File then “Quick Import Sample”.

image

Then click the Load button to load the sample.

Quick Import Vocoder

image

Follow the same process as for loading samples and select “Quick Import Vocoder”. This loads your source sample (vocals, drums…) into OSC2 of Synt1 which is auto-configured as the Modulator. Synt2 is auto-configured as the carrier with an Ultrasaw synth method for Osc1 by default.

image

You can change the character of the synth sound by programming Synt2. I want to point out that ElectraX has no routings for processing and external audio source as a modulator in real-time. Nevertheless, being able to trigger modulator samples from keys is a pretty handy way to do vocoding.

Wavetable Creation
You can quickly resynthesize sample data and then use that as a wavetable controlled by PW (pulse width).  Change Osc type to “Wavetable”. Click the “Resynthesis” label to load an audio sample. PW1 now sweeps through the wavetable. In the screen shot below you can see I’m using LFO to modulate through the table. image

Below is an excerpt from the manual the describes how waveforms are imported based on sample length.

Saving Patches with Wave Data
With many sample-based instruments, the waveform data referenced by the synth is stored externally in a folder making it necessary to extra steps to package up the patches and sample files to share with others.

I was excited to find that when a patch uses Sampler, Vocoder, and/or Wavetable synth types that the sample data is automatically stored in the patch (.fxp) when you do a “File->Save Patch”. Woot!

Rapid Patch Programing with Original Harmonic Content
While ElectraX isn’t intended to replace a full-on sampler, these features will allow you to quickly incorporate original harmonic content into your patches. You may find yourself reaching for your sampler less with ElectraX in your rig.
