are you missing a screw??!!

 

Sometimes it happens so .. When i started working on the box i noticed the screws on the original panel as they were non standard ,so in order to save them i put them back on the front panel once i got the panel out .Somehow in a month or so , while working on the electronics that panel got lost somewhere in the basement ,and when it was time to start populating the panel i made i just couldn't find the screws Now there are 4 ugly holes that i need to mask somehow ,it ruins the picture a bit but i can live with it . 

The enclosure as factory made provides 2 rectangular holes just exact fit in the back to add 6 banana jacks ,i made those four individual sampler outputs plus a mix output that is the selection made with the white push buttons from the bottom of the panel , and finally ground .The DIN socket connects to external PSU.

 

 What i learned from my previous groovebox proves to be right , i installed a switch from the main clock to the 208 Music Easel Random Section ...cause when it stops clocking the Uncorrelated Random remains at that random last step . 

Other feature i find useful is having one of the excite inputs of the Neural Pulsers at the bottom of the panel where it's easy to tap with your fingers cause one can trigger a neuron in such way (sometimes...) ,along with the potentiometers at the bottom of the panel for easy access it's performance friendly ,while most of the patching is done in the middle of the panel ..

The little box in the background is a fifth voice ,another Hagiwo Sampler with additional XR2206 LFO ,and Synthrotek Dirt Filter .

Another GrooveBox is finished. This time with 4× Hagiwo Sampler Drums, CGS Gate Sequencer, Yusynth Pulse Delay, and Buchla 208 Random. Instead of a regular kick and bongo, there are samplers — that’s the main difference from the previous machine. Together they now hold 240 sounds, each 600 milliseconds long at 48kHz.

The enclosure was something I found lying in the mud at the junkyard. It looks like an old fiscal cash register, or maybe some other device. Sometimes you can find boxes from medical equipment there too. Cleaning off the factory-baked paint wasn’t easy, and this machine changed its face several times before I finally completed it.

As always, some things could have been done better.

One more panel design ...

 

This elaborate single panel synthesizer contains the following modules :

Buchla 258 (Single VCO)

Ian Fritz 6 Phase VCO 

Ian Fritz /R.C. Bass Waveshaper (Electronotes)

Serge Triple Waveshaper 

Paparail VC Aux / Panner /VCA

Yu Synth Dual RIng MOD

Wiard Wogglebug 

Serge DUSG + USG

Serge Smooth / Hagiwo Bazier Curve x 2

Serge Extended Resonance VCF

Serge '73 VCF (Both with summed outputs)

Osamu Hoshuyama Dome Filter

Buchla 106 (Half) + Electronotes VCA

Serge Noise

                                                                  

Mixer

 I rehoused the Mixer i built for myself as the first build had no printed panels ,the cheap switches i used for muting the channels started failing ,and there were too many wires using converters for each banana - jack i use , so i made it all standard 4mm banana sockets except a few ,i had to minimize so in that sense here i am missing two limiter/saturators and one optical compressor and a joystick panner and they will need to be in a separate box , instead i included here a small 4 channel filter bank based on schematic i found at electr-music . This is just basic mixer and actually a Buchla 106 ,with additional 4 mixers from Serge Schematics used as aux channels , there is also 3 SIAM Equalizers .

a little mess..

 

SInthai Solo

 

This little monophonic FM synth is based on Hagiwo's FM Oscillator ,it's just Arduino with the help of AI and therefore not Duophonic at least , but i decided to keep it , it's got 7 waveforms ,envelope ,pitch bend with 2 semitones ,range and depth controls , there are dedicated cv inputs for all these functions , now there was room on the panel to add a simple envelope generator as there is pulse out on keypress at D1 , but guess i'll just do that part separate ,the Joystick is just voltage source to modulate inputs . It's all done on stripboard .The keyboard is cut out from larger Casio CT660.

Homemade Groovebox

 This is a Home made Groove Box i built . It features Experimental Hardware Neurons from Wiard as the trigger sequencer ,voices include 2 x Hagiwo Samplers ,1 x Hip Bass Drum from Craig Anderton and two NLC Bong0's stripped to only two inputs and an output . There is also 194 Buchla Bandpass Filter and 106 Buchla Mixer ,99dsp Effects from Aliexpress ,a Colorupter Optical  Compressor ,and 208 Uncorelated Random from Buchla paired with CD4052 Pattern generator to sequence thru the sample select or sample banks . 

DIY

 Playing around with a homemade Serge 

Homemade Serge

Simple pattern on my big serge-a-like modular ,few years ago ,before i sold it to pieces ,here using 2 x VCS ,a VC ADSR ,SSG and 73 VCF by Serge

 

it's complicated

this project is done.

Radio

 few modules that were left over from my big modular synth ..in a old radio box enclosure ,still few more to add here 

.

so  i can't afford it
