DIY Analog Synthesizer Demonstration

This is my DIY Synth. Using schematics from Ray Wilson, Thomas Henry and Marc Bareille, i've bulilt my owm machine featuring:

2 XR VCO
1 24dB Lowpass Filter
1 12dB State variable Filter
2 ADSR
2 VCA
1 LFO whit S&H
1 white noise generator
1 MIDI-CV (mcv876-4CV)
there is also a modular section in the lower-right corner of the upper half, allowing to reach almost every output&input of the single circuits. Patching an input overrides the internal connections to that input.

The XR vcos are great! Those allows continuous variation (called SKEW) from triangle to saw and from sine to "rampoid" (sort of saw with sine-ish decay) waves. I added sync switches, fm switches, lfo to skew, lfo to pitch switches, vco to skew switches.

The 12dB filter has a special feature: beyond the LP, BP, HP output it has an output wich continuosly blends the LP and HP outs according to the LFO signal

the LFO outputs saw, ramp, triangle waves and a S&H stage output. The S&H is clocked by the LFO and feeded with white noise.

Apart from circuit schematics, I made everything: PCBS, enclosure, panels, knobs, labels. The enclosure is made of walnut and can be closed and carried as a suitcase.

once closed it measures (HxWxD) 23x33x14 Cm and weights around 6Kg

took many hours of work and cost me something around 250€

This is awesome, very similar to what I am hoping to build eventually. I just built a soundlab mini from Ray Wilsons site. The only things I might do differently then you is add another LFO and VCO. Also I want one of those pin matrix patch panels like the EMS synths have.

Thanks!

Another lfo would be a really nice add! Search for a GOOD schematic (mine is pretty weak!) with wide sweep range, midi sync, many waveforms.

And a ems- style patch matrix would be awesome, search for the beautiful JH matri FX by Mr. Jürgen Haible for some ideas.

NIce!

I hate U!

:) thanks

[SHUTUPYAFACE]

you got any links of where to get started on this stuff? and any links of those schematics you mentioned? thanks

[GVNZ9]

Yes! You can find many schematic and resources on Ray Wilson's site:

Great sounds! I'm thinking about building something similar myself, any suggestions?

The XR-VCO is cool. I just built my own (videos on my channel) However, I went for a modular approach to allow for some really wild sounds.

@rabidmongoose51 Is that pin matrix thing hard to make? because i want to make one of these but i don't know how...

[Redled72]

Nice Work.

[MerrickHard]

Gorgeous work, from what I can see. Love to see a higher resolution video if you get the chance, otherwise, more videos please!

[neandrewthal]

Impressive work. Great job!

Thanks!

Good video and amazing synthesizer, I've posted it on switchedonsynthesizer.blogspot . com
