"Late 1960’s or early 1970’s Shin-Ei (Univox) 4 In The Floor Percussion Combo analog drum synthesizer pedal unit.
Works and is in good cosmetic condition (see photos). The four food pedals trigger kick, tom, clave and snare sounds. Rotary trim pots inside the unit (mounted off of circuit board) adjust the envelope of each sound, from very short duration to a nice decay to full-on self-oscillation. Four volume sliders (one knob is missing) control each sound’s level. A rotary “repeat’ control on the side adjusts the speed at which the snare sound repeats for ‘fills’. Runs on two 9-volt batteries or 9 volt power supplies (not included). One of the battery clips is a little flaky and may need additional attention if the unit is to be moved around a lot for gigging. A printout of the schematic is attached to the bottom plate. The screws attaching the bottom plate are not original to the unit but do the job, and one of the rubber bumpers on the bottom is also a replacement.
The sounds are classic analog drum machine, and the ability to adjust the envelopes for each of the voices allows for a lot of sound-tweaking possibilities. All four spring-loaded foot triggers work great. There’s a couple youtube videos demoing this unit that provide examples of the sounds this unit can make. I’ve noticed that if the batteries aren’t fully charged the snare sound is the first to drop down to a click, and in fact on the bottom of the unit it is printed “Replace both batteries if the snare effect become bad or the sustain of other effects become insufficient”. If you make sure to unplug the audio cable when not playing it the batteries won’t get drained (and there’s no power indicator light), but I’d recommend using a pair of plug-in 9 volt battery eliminator units as they will provide consistent power even if you leave an audio cable attached for days at a time."
"This is a demo of the Noise Engineering Basimilus Iteritas Alter. I go through all knobs and functions and show you two patch ideas.
The Basimilus Iteritas Alter is an improved version of the discontinued Basimilus Iteritas. The 10HP six-oscillator additive synthesizer comes with adjustable waveform, harmonic spread, attack, and decay summed and fed into an infinifolder. They call it a parameterized digital drum synthesizer.
"This is a demo of the Noise Engineering Loquelic Iteritas digital eurorack VCO. I go through all knobs, explain the algorithms, and show you two patch ideas.
The Loquelic Iteritas is one of the earlier VCOs from Noise Engineering. It has three modes that are based on interpretations of three classic synthesis algorithms (VOSIM, summation synthesis, and phase modulation) involving dual pitch control.
"Come and join me on a journey to explore Chaos by Clank.
Chaos is a six-channel random generator that can easily be used as a sequencer, modulation generator, clock source, cv pattern generator, voltage recorder, and many other things.
"This is a Xaoc Devices Zadar 1973 quadruple envelope generator tutorial. I go through all knobs and functions and show two patch ideas.
Zadar is a four-channel envelope, modulation, and transient generator. It creates envelopes from hundreds of shapes using vectors that can be stretched, flipped, warped, distorted, delayed, shuffled, repeated, and amplitude modulated in real-time."
"This is a demo of the Mannequins by Whimsical Raps Mangrove formant oscillator. I go through all knobs and show you three patch ideas.
Mangrove is an analog formant oscillator that contains a triangle-core with a dedicated square wave output and a shaped impulse-train generator output through an internal VCA and waveshaper.
Many of the brands in the world of Eurorack modular are small businesses that produce in small numbers. To me, it is deliberating that not everything is immediately available all the time and every once in a while there are modules that are on backorder, out of stock, or out of production. With its unconventional and inspiring design, the Mangrove formant oscillator is highly regarded even years after its release. I think it is well worth the hype."
"In this video, we are taking a closer look at the ALM Busy Circuits MCO compact digital Eurorack oscillator. I go through all knobs and waveforms and show you three patch ideas.
The MCO features 10 morphing waveforms with a resolution of 16Bit/48kHz (AKM audio codec). It has a morphing wavetable out, additional variable pulse segments out (think Alpha Juno style saw wave PWM), and a sub-square wave out. It is said to have an early 90s slightly crunchy digital type sound (like Ensoniq or Kawaii Kx synths)."
