I have been having varying degrees of success building a simple VCO from the designs in Thomas's book Making Music with the 3080 OTA.

The VCO section is working nicely now on my veroboard design. B ...

Thanks Yves

I have swapped all IC's with a known working VCO one by one and still no luck.
Power to all IC's seems fine.
replaced the J112 transistor.

Not a sound - very frustrating!

Thanks Magman

They look like a very handy supplier. Might just get one as you say just to test

I have managed to breadboard a pretty decent VCO using the 3080 anyway so I'm going to run with th ...

Thanks - unfortunately I am in the UK so dont fancy paying the postage and duty on a few little IC's!

I have plenty of other parts about so I may try to build a VCO from a CA3080 (I have a bunch of ...

I have tried several from the same batch. Maybe I'm just being an idiot and missing something.

It is a shame thought that all the VCO chips in Thomas's book are discontinued - it's a great book an ...

I accidentally put a large voltage through my Yusynth VCO and burnt it out. The 2 resistors on the power input burnt out. I replaced them but it no longer works at all.

Hi
I'm not a newbie to synth building so I may be a little embarrased here.. Smile

I have just got hold of a bunch of 2206 chips after purchasing a copy of Thomas' VCO Chip Cookbook.

Hi Marck

thanks man. Sorry to get too serious there! I thought you might be one of THOSE people Wink

telstarmagikistferrari... you are correct that there is a digital sequencer AKAI MPC2000 used as is listed in the gear.

I hope people here would be interested in my new project.

I've been doing a lot of searching and found good examples of standalone step seq's which output MIDI. And I see many of you use MAX/MSP to send CV/gate from an Arduino.

Hi
Anyone here built or used the MCV876 MIDI-CV inferface by Marc Bareille?

I have just put one together which seems to work okish . Unfortunately the control software is only for PC and I'm on a ...

Fer sure it's too small!

Tried unplugging a few other modules and the new VCO is fine now.

Just ordered 50VA torodial from Farnell.

We live and learn. Wink

Just put DVM across PSU. Measuring almost 500mA across the -15v to +15v rails.
More important, just noticed the transformer is rated for 250mA.... Confused

I guess that's not good!

I have just finished my second VCO and when starting to calibrate things got a bit wierd.
All scope readings were blurred (ie multiple ghosting waves) so almost impossible to set. Thought my scope wa ...

Just wanted to share this. My first set of modules now making a lovely noise!

Excuse the cheapo front panels (A4 paper and clear adheasive tape! Stuck onto aluminium panels drilled by hand no less) ...

I have once again discovered the depths of my ignorance and will tomorrow be building the AC coupled version.... being as that's what I need to do the job...
Embarassed

Nice one Yves
Good and simple circuit ... I'll be off to buy a breadboard tomorrow then!

I did put the VCA together without matching but it sounds pretty bad! Splutter, distortion and cutting o ...

Being newish to this I'm unsure how to match the BC547 transistor pair.

If they are from the same batch are they likely to be matched anyway?

If not how do I match them without any special equip ...

Nice one Yves.

I notice the jumper is missing in the new layout also. Is this intended?

I have just started populating the board for my ADSR module and notice that the JPEG and the PDF are slightly different.

I think R4 and R5 are wrong on the PDF (1k and 22k should be 100k and 1M..?) ...

After a few days of mulling it over I realised that everything could be so much simpler.
So I decided to employ the best best test equipment known to man.

MY EARS!!!

Thanks. I get the concept of having to go in the opposite direction what one might think. That's not the problem.
The difficulty is that once I start tuning the second or third octave etc the octaves ...

I had been annoying Yves on his private email with my questions but have just discovered this place. Great!

Just finished building my first VCO and incredibly it works first time and beautifully. M ...
