4Fade - Quad VCA Mixer for Eurorack Synthesizer

video upload by NoisyFruitsLab

via NoisyFruitsLab

"4Fade is a quad, stereo, linear VCA mixer around 2164 ICs with pre listening stereo headphone path and expanding features.

It delivers clean sound and clickless mutes around quick and high quality vactrols. Still vactrols deliver a slight fade out when muting.

Each channel has a gain stage with boost for low level signals and the level can be controlled

over common eurorack voltage for further dynamics like sidechaining, or DAW automation (MIDI / USB to CV needed! )

The 45mm channel faders got a LED for indicating the level.

The cue path is pre listening, but before the gain stage. A result of keeping the circuit as clean and small as possible without adding another series of VCAs.

So keep in mind, pre listening with gain down only!

The audio inputs are normalized from L to R for use with mono equipment as well.

The sum of all channels leads into a master volume pot and gets indicated over a 10 digit VU meter display after all.

On the backside are connections for the dual send expander and the 5MX stereo mixer to get additional channels.

Together they form a 9 channel mixer with a flexible send path."

606ish HiHat for Eurorack Synthesizer

"A modern approach to a classic and legendary sound element.

It´s designed around Schmitt triggers in common Roland tuning scale.

It offers CV in for decay and tune, an aggressive tone control and a pitch for tuning the Schmitt triggers.

"Kick V2 is a major update to the famous 808 Kick that has been available previously.

It still delivers the classic 808 sound and way more than that.

Now with 2 CV ins for accent and pitch and it can be formed to a various of kick sounds including a charming diode distortion at the end.

SPROOM - Multi Effect Engine for Eurorack Synthesizer

video upload by NoisyFruitsLab

"Sproom, half space half room.

It´s based on the FV-1 DSP IC by Spin Semiconductor which got popular with some famous guitar pedal effects and is covering all types of quality reverbs, delays, chorus, flangers, tremolos, or combinations of them.

It´s stereo and operates with 6 MIPS at Fs=48KHz, or in other words excellent audio quality with a clean dry / wet path to adjust the amount of effecting.

It offers 3 banks with each having 8 different algorithms. In total 24 effects.

The input is normalized to R. Means with just plugging a mono source into the left input, the output becomes stereo.

Each algorithm can be controlled with one of the 3 potentiometers, or by conrol voltage.

Capable of -5 / +5V with the dedicated pot at around center position, or 0-10V with the pot fully closed. In other words, the pot acts as offset.

LED indication for clipping and CV ins.

The internal effects are tied to the IC and fixed. Bank 2 & 3 or EXT1 & EXT2 can be exchanged with EEPROMS on the backside.

FM4 - FM Radio for Eurorack Synthesizer

video upload by NoisyFruitsLab

"FM4 is a classic radio FM transreceiver like many of us know from ancient times.

It delivers all what we love and hate around radio circuituary from the 80s with charming bandwidth, sound characteristic, noise, athmospheric limitations and interactions.

The name FM4 is a tribute to my favorite radio station around the alps that caused a massive impact to my musical education.

It wouldn´t be a eurorack sound source without CV inputs. There´s CV control with attenuation for tuning and level control while the main pots act as offset control.

Makes it a fantastic random chopping source for all kind of artifacts you will find in the FM universe and of course you can listen to radio stations in a classical manner.

As antenna you can use a typical eurorack wire with around 45mm.

The graphics around the antenna got some fancy LED indication that shows the final output stage.

LED color options are available at checkout.

Note: The unit is calibrated to 102.1, the only one radio station that matters :p. In case of athmospheric temperature & humidity changes more precise calibration can be done with a trim capacitor on the backside."
