NAMM 2017: The Eurorack Tape Echo

Danish manufacturer T-Rex Effects introduced their dual tape echo eurorack module which had started its life as a stompbox a while ago. No doubt that they made the sound warm and the CV ins smooth enough too.

Those who were waiting for their tape echo which won’t cost a fortune and can be integrated easily into their eurorack modular synths shall be delighted: The T-Rex Effects Replicator has a lovely sound, and the pedal had been already praised by a lot of users.  The CV ins are also slewn, so no harsh or “weird” modulation signal will eventually kill the motors or the tapes.  Talking of sound processing: its 8dB boost can send your already thick eurorack waveforms on a waveshaping holiday. The chorus and built-in filter produces smooth and subtle effects strictly based on the raw components’ and signals capabilities! It is worth attenuating the input signal though for softer and more minute effects. At ~8,7Vpp most oscillators and digital audio outs will be fine, though louder and more dynamic effects of some drum modules and tube modules might get distorted earlier. …We have just scratched the surface!
If you maintain it (demagnetisation can be done with ease, plus the tape heads which are also accessible need cleaning time after time), this module will never let you down.
Size and consumption should be considered: it is a little bit bigger than half of a typical eurorack row (44 HP), but in the age of big cases, it has become essential to provide your modules with enough power (4ms ROW POWER 40 or a ROW POWER 30 power supply modules will do he job).

Modular Minutes: Kasleder Effects Acid Fuzz In Context

This episode of Modular Minutes was shot in Banyek‘s home studio to put the Kasleder Effects – Acid Fuzz module into context! The Hungary-based eurorack module sounds sweet everywhere, adding delicate and conveniently controllable textures: in a word _more life_ to your audio signals.

Screen Shot 2016-03-30 at 13.52.28 (2)Modular Minutes is a new series from Analogue Zone’s Budapest showroom – the series aims at the finest and latest modular goodies with patching comprehensively described both in comments and the description tab.

The Kasleder Effects – Acid Fuzz adds those sought-after flavors to your tones that are not just simply “vintage” thanks to the ultra rare 70’s germanium transistors, but also bring up controlled levels of organic colors, that just keep on breathing new life to every audio signal input you have. Every setting is different and decent: results are immediately pleasing and convincing. Thanks to the CV inputs and the depth and ease of controls, the module can find its place in any rack with the not the least amount of dilemmas left behind!

"Eurorack fuzz is a brand new concept" - Kasléder Albert-interview

Having a new start is pleasureable and challenging at the same time. In the age of digital eurorack modules with a plethora of functionality involved, it is most demanding to reconsider a few options that not only had not been available earlier in a voltage controlled eurorack format, but also address the ones that will indeed enhance the sounds of a 21st century modular synthesizers. In this piece we were in conversation with new eurorack maker and well-established stompbox manufacturer Albert Kasléder, of Kasleder Effects.
“I feel home in a guitar-based world.””
Kasleder Effects, having a lot to offer already in the stompbox market with their hand-made fuzz, distortion and other processing effect pedals is about to bring a lot to eurorack which will work out as a novel concept, and also as a great new playground to the maker himself.
“Having met András (from Analogue Zone) again on a friend’s wedding, we started a long contemplation on my first then future eurorack module. In 2015, the eurorack fuzz concept had been relatively new and not realised yet, the chance was lurking around, and there was no question where we wanted to start. Having made similar circuits in the last 10 years or so, we started out from a fuzz effect that I had made earlier.Making the Acid Fuzz modules was half a year spent with serious design and testing work. It was a good chance to have myself tried out in this aspect, but the users will tell whether I succeeded or not.”rt.
Kasleder GE Acid Fuzz Modul elejeTesting was a tough and fun time either. Albert had to focus on “only” two things: implementing votlage control to all parameters while not losing even a bit of the sound. Adding voltage control to anything is a non-standard process and can be realised in many ways. The results are pleasing and for the first time ever, the user can have a decent and ever-interesting palette of fuzz/amplification/limiting which can be even more integrated to any kind of synthesizer system. Check the manual for patch tips and detailed description of the parameters.
What is fuzz though by the way, and why would I need voltage control over it? It is simply speaking an amplification that does not end up in distortion but offers a more sparkling, “toasty” amplification and limiting on the input signal. Imagine adding soft to very harsh grains to your waveforms without even distorting them. Imagine it under common voltage control. Imagine CV signal processing with it, and I’m sure your mind will start working. You have to apply the right parts though to have a sound you dare call fuzz. In the Acid Fuzz, the NOS (new-old-stock) ultra-rare germanium transistors do offer that. 
DSC_0340The module was tested and developed in live situations: one decent result was how the original stompbox reacted to feedback, so a completely new circuit was desinged for that as well. Having the ability to soften the bright fuzzy textures of the input signal in this way is also a novel concept. It is just about tuning your sound the way you want it to be. Not to mention the looks. The panel graphics has great looking out of this world alien cartoon-narrative which is refreshing and inspiring to look at – made exclusively by Eszter Budavári. The good quality panel-mounted pots also offer enough space for live tweaking and convenient setting in the studio.
The maker just won’t stop here though:
“I do have a lot of concepts on my mind, but since I am only getting to know a lot of circuits, I’m sure I will even have more ideas on the go as I’m looking at more and more eurorack modules. One thing I will always keep as a primary method is, that I will always use the best quality parts assembled by hand, providing a no-compromise solution even to customers with the most specific needs!”
