Kijimi VCA RC Filter Demo

video upload by Sonic Sand Castles

"This is an A/B test of an RC filter PCB I made to filter out unwanted amp envelope artifact/aliasing noise on the Kijimi voice cards due to low-res DAC amp envelope outputs going into the VCA CV inputs, compared against the default AS3360 DIP ICs.

The PCBs I made just put an RC filter in front of the VCA CV inputs of AS3360D (SMT version) ICs.

The RC filter values are:
- 1k ohm resistor
- 0.47uF capacitor

This was just a quick reversible solution I put together, no direct soldering required on the voice cards or main board.

The first section demonstrates the unwanted aliasing using the default DIP ICs compared to the adapter PCB which filters it out.

The second section demonstrates how the adapter board reduces the strength of the envelope (which is a drawback, but I prefer that over the artifact noise)."

Seriously speedy Stylophone playing!

Shin-Ei Univox 4 In The Floor Percussion Combo Companion

Pics of the inside below. You can find a demo of one here.

"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."

A Digital Voice for Drums Bass and Lead: The Noise Engineering Basimilus Iteritas Alter

video upload by pitch patch

"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.

You can get further information and the manual here: https://bit.ly/basimilus

I use 100% raw audio: no preamp, no compression, no effects.

"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.
