Author TriTone - 3 band EQ, filter, saturator
igorrr

TriTone is a three section EQ plus saturator. Inner knobs control frequency and outer knobs control +- gain. All these sections Hi Shelf, Band Pass and Low Shelf are having + 20 db of gain and 30 db of reduction. Each section can work independently or they can be serially connected by the switches. Middle input in each section accepts CV for its frequency, so all three sections can be individually FMed by the external CVs.
If the inputs are fed with the modular level signals (+- 5V), then there is little room for “plus” EQ gains before saturation starts. In this case the input level should be attenuated first, if saturation is not desired and much “plus” gain is needed. Otherwise saturation drastically enriches the tone and the module works like very flexible overdrive FX.
When the switches are set to upper positions, then all three sections work independently. With the maximum gain reduction (CCW position) of the upper section (Hi Shelf) it becomes a useful kind of Low Pass filter. On the contrary – maximum gain reductions of the lower section (Low Shelf) makes it a High Pass filter. These modes are shown in the video.
Please note the internal routing done by the switches: the output of the uppers section is added to the input of the subsequent lower section. If nothing is connection to this lower sections’ input, then only the upper section’s output is processed. This makes it a 3 band EQ with the switches set to lower position. Having separated inputs opens up more possibilities over ordinary EQs.
Different feedback routings are possible even without any external modules involved. The video has a moment when output of mid section is connected back to its input, which adds more power to this section.

Looks great. I can't help but feel they should all have connectors on the back to allow less cable build up since they are all identical format. This is great and let's talk about that filter asap.

Cool module concept and implementation.

Wow! we're not worthy SlayerBadger!
igorrr
TriTone is currently at Schneiders Laden showroom, so can be checked there.

Lovely design Igor! SlayerBadger! Added it to MG.

TriTones are now available at Schneiders Laden

Whats the frequency ranges for the three bands?
igorrr
Manual sweep gives 20 Hz – 15 kHz range. With CV applied can be made a bit higher.

What is the depth of module and power specs?

Also, do you have a US distributor?
strangegravity
Impressive. I like all of your designs.

Depth is 4,5 cm. Will inform the power specs in a week.
TriTone are just restocked at Schneider’sLaden.

Thanks man, You are the best. I'll be in touch via email.

TriTones can now be bought also from Midi Amsterdam shop, plus checked at their showroom.

nice one!

Is it analogue ?... eek!
igorrr
Fully analogue.
Takes 55 mA from positive supply
and 65 mA from negative supply

If you switch it to 3-band EQ, will it process three different sound sources--say three VCOs--the same way?
igorrr
When the switches are set to upper positions, then all three sections work independently. And you can feed tree oscillators to the available inputs. There will be HiShelf for oscillator 1, Mid for the oscillator 2 and LowShelf for the oscillator 3. Each output will have only one oscillator processed. Or you can route HiHat to HiShelf to bring some high frequencies, Clap to Mid section and Bass Drum to LowShelf section.
When the switches are set to lower positions, then output of upper section is summed with the input of lower section and processed by this lower section. HiShelf for oscillator 1 is mixed with oscillator 2, and then this mix is processed by Mid Section, after that the result is summed with oscillator 3 and processed by LowShelf section. If only one input signal is connected to upper input, then it acts as ordinary 3 Band EQ.

This sounds like a really interesting way of mixing signals. Nice.

Any plans for distributors in the USA for this or the new filter module?
igorrr
I should get the soldered boards soon, so will be able to supply US market this month.

TriTones have just arrived to US:
http://www.analoguehaven.com/happynerding/tritone/
And here is the demo showing TriTone being used as Distortion/Overdrive effect. Mostly all three gains are at maximum, which is around + 20 dB for each section. And frequency of each band is varied for different flavors. 303, electric guitar, drums and syths sounds are shown in the demo.


I think this module can replace a bunch of dedicated pedals, because it allows more tone variations than ordinary “Tone” knob.
