New Barton Musical Circuits BMC116 VC Burst Generator & BMC109 VC Distortion

video upload by boogdish

"Takes a gate/trigger input and outputs a burst of pulses. The amount and speed of the pulses are controlled with knobs and control voltages. Can be set to a specific number of pulses, a random number or pulses to fill up a specific amount of time.

Compatible with 12V or 15V systems. Can be used with 9mm or 16mm pots, my panel is designed for 16mm pots."


BMC109 VC Distortion Demo

video upload by boogdish

"A VCA circuit in series with a clipping circuit creates voltage controlled distortion. Two independent channels, can be used as a waveshaper or as a VCA that adds harmonics.

Compatible with 12V or 15V systems. The Pots are PCB mounted, but all other parts are mounted off board."

Gijs Gieskes WD80 Solar Powered Touch Synth

video upload by Gijs Gieskes

via gieskes.nl

"A solar powered synth where the solar power is integrated into the interface.

The WD80 refers to WD40, my French neighbour made the joke that it sounds like it needs WD-40, so i decided a good name for it is WD40 (i changed it to WD80 because of personal reasons and because WD40 is copyrighted).

The idea behind this synth is that you power it from the sun, but that the power is not just providing power, but it also acts as part of the interface. When there is less light the voltage goes down and then the frequency is also going down. When you use the synth you can walk around and for instance a tree above you will make a shade with allot of branches, this will give nice modulations in the sound especially when the wind blows a little bit.

It is using resistive touch contacts, so you can turn on the sound on the left side with one finger and the sound of the right side with another finger. There are two switches to turn on the left and right side on permanently, but it will be less loud then when you touch it. it will also be a little low pass filtered it seems when the switches are closed. So then when you touch it the osund will be louder and teh lowpass with be gone while you touch it.

The potmeter starves the power of the IC (HEF40106). The socket is a DIP socket so you can also try other versions of the 40106 series, for instance the CD40106, it might sound different.

The circle is connected to a oscillator that runs by itself, it is not directly connected to the output, but it somehow effects it allot.

The 4 lines are connected to 2 schmitt trigger circuits of the 40106, the center two lines are connected to the outputs of the schmitt triggers.

The output can drive headphones, there is no volume control so if it is to loud for you or the volume is to low you can use other headphones. I am using Sennheiser HD480ii.

For use in concerts you can use a halogen light to power the synth, and because it uses you bodies resistance to transfer the sound you can get hum (50hz or 60hz). To reduce this hum you can use a hum reducer that i am also selling."

NTS-1 mk II - building and jamming

video upload by Tweeeeeak!

"Building my NTS-1 mk II, where I'll be testing my future custom oscillators, firstly the ones ported from mk1.

(Check my custom oscillators for NTS-1: https://github.com/tweeeeeak/nts)

Audio from my first jam using both mk1 and mk2.

Mk1 playing Proba-B OSC with arp filtered by the auto probability sequencer of the Proba-B OSC (Function 8) + 'Corrosion' mod FX + delay and reverb. Audio goes through mk2 but bypassing all fx.

Mk2 playing SQR OSC with a recorded sequence on random order + some mod FX + delay and reverb. Reverb is quite wet on the first part of the video and gets dryer somewhere in the middle."

System1 - Raspberry Pi ML

"I’m really excited with this new setup of a System1 into a Raspberry pi running IMPSY(written by @cpmpercussion ) which predicts musical control data in a call and response manor and returns it back to control 8 channels of the System1. The IMPSY system is trained with data from the System1 as it is played."

"A one of a kind Eurorack sequencer and case ( 3 x 126HP).

This case was painstainkling crafted from aluminium extrusuions and 6mm hoop pine plywood. It has removable aluminium legs at the rear that posistion the case on an ergonomic angle.

Inside the bottom of the case the 'clock' is mounted. The clock consists of a geared stepper motor 5:1 driving an aluminium arm with magnets. These activate reed switched on the four different time tracks on the custom made circuit board, 4/4,5/4,6/4,7/4, over 8 bars. The stepper motor is driven by a stepper motor controller, this is connected to a panel installed in the lower left position of the eurorack. This panel has an input 2.1mm barrel socket for a 12V (1A Min) supply, a enable switch, a pulse switch and a direction switch, there is a 3.5mm socket for the input pulse from the oscillator; (the frequency division of the oscillator can be adjusted by dip switches on the stepper motor controller). The oscilator I used was a Doepfer A-145-1 LFO set to High range.

The time signatures are then available over 14 'channels' to have each step turned on or off by the array of miniture toggle switch on the control panel over the 8 bars. The ouputs of each channel are available on 3.5mm sockets on the output panel mounted center-top on the eurorack rails. This panel also features the following outputs - 1 every 8 Bars, Kick drum 4/4, Off beat, 2,4 and 2,3,4 on 4/4 time. Also direct outputs for each time signature.

The case also comes with a custion beat counter module, this displays the BPM in binary.

A selection of spare parts is provided, including - a stepper motor and gearbox (high precision) reed switches, toggle switches, diodes.

Note - this device best suits those with some electronic skills as this device will likely need servicing at some stage. Also it my require trouble shooting should it become damaged during transportation. It will be well packed and marked fragile. The damage will like be a solder joint becoming faulty it the device is bashed about. The circuits are very simple and easy to trace. The 'clock' board is mounted to the botem panel that can be 'quickly' removed from the bottom of the case via wingnuts."

A Bit More - starting to come together

video upload by Craig Barnes

"This is my 8 voice bi-timbral poly synth based loosely on the Crumar Bit series of polysynths. The 8 DCOs are sent note on/off messages over midi on individual midi channels from the controller board. Common commands for octave shift etc are send on channels 1 & 2 for each half of the synth.Just testing the polyphonic control for Poly 1, 2, solo and unison."

Din Sync RE- 808 TR 808 Replica

The missing Din Sync logo through me off. You can see what one with looks like with the logo here.

According to the listing:

"The special thing about my replica, however, is that I had the housing overmolded. Among other things, the DinSync logo has now been replaced by the Roland logo. Now it really is as if you had a real 808 in your studio. A real eye-catcher!"

Another note from the listing worth capturing:

"It should be mentioned that the “Accent” and “Cowbell” trigger outs on the rear panel are internally reversed. However, this was a mistake in the wiring diagram at the time but it does not affect the function in any way."
