cv input

[jw hagenbeek]

hi is it possible to bypass the 5V and use the cv output from my
sequencer to control the auduino???

i hope so, than i will use my baby10 to control the synth!

By control the auduino do you meen give input to it?
if yes it is no problem, I dont know what voltegs the CV giving out from your baby10 but on the digital ports 3-5v gives high input, if it is a analog port you desides what level is high!
if the voltages is over 5v you just need 2 resistors to break down to 5 volt.

Hope this helps

I have been working on a safe way to add external control voltages to it with a reference voltage safety. So it will never go above the reference feeded by the arduino itself and also will never go below zero.
I am designing an eurorack interface for it now and will keep you informed.

sounds good! how about basic diy vactrols, LDR+led?

No direct input with safety schottky's is better to control

Wow, great! It's alive! Big thumbs up for this!

Do you need help with designing the front plate? I know a few designers who are fully qualified for the job and most likely would do the design if they get one free faceplate in the mail? I could ask if you say you want/need help.

Not trying to featurecreep or anything, but just a few ideas came in mind ;) :

Looking at the backside gutshot, it would fit in a few HP less, yes? Also, a few indicator leds could be nice?

Would it be possible to add a function for selecting between modes, like chromatic, minor, major, egyptian?

Could there be additional waveforms, is there enough memory available to add functions like this? Do you think people would appreciate these features? Is there a possibility that the device could easily turn into a multi-purpose module that could be reprogrammed by users, like the Snazzy FX ArdCore?

Thanks!!!

I will draft some frontpanels first ;)
I understand there is a lot more possible with the arduino and I respect the work of snazzy fx, in that way i am not willing to recreate something like the ardCore. After testing some hours I realized the A4 and A3 inputs give most influence on the sound (my previous auduino in my modular also only used these inputs for the same reason).
And I am going to invert the inputs as 0V is high pitch and 5V is low pitch, that is a little weird in combination with cv inputs.
My final goal is to make a simple and cheap DIY kit which can be assembled within half an hour. Most probably I will give workshops with it. That means it has to be straight forward (... and the ArdCore is not that straight forward) and fun to make. Code writing is not that fun for most people and I don't believe a lot people will do this as it is functional directly after you made it.
Your idea about the waveforms and mode is a good thing I think as the basic principe of the module stays the same.

I don’t know if you are aware of this, but I started and run a local synth club here in Finland, we are 743 members in our facebook group right now and also arrange workshops now and then. Our synthclub is active in 3 cities, with people arranging meets/gigs/beer-nights quite actively, at least on a monthly basis + We also arrange the annual synth meet in our country. 

Ten of us gather together every wednesday to do DIY soldering here in Turku, Finland and other cities are trying to work some similar activities right now. I think this Auduino/Euro project you are making here, as a kit / workshop would be a great project. Just let me know and I will make sure the word gets around here, and I’ll try to set up an workshop / group order!

My friend Olegtron, will have an art installation in a few weeks and the Auduino is part of the installation. I will try to capture this on video and post it to all of you to see.

Here’s some rough prototyping, interfacing the 4060 with the audiuino. http://youtu.be/NLduXv3_nLY
