R.I.P.

I just saw the datasheet of the 40105. It's essentially 4 16-bit shift-registers, with common clock - and then some more. It should be ideal for this application, shouldn't it?

Check out the solution that Fonik used for this:

Hi!

I want to learn how to designs euro format PCBs suitable for "production". Help me!

I know enough electronics to at least build some digital stuff (uC etc) with analog interfaces. ...

Might be obvious, but do you have a resistor to ground also (after the diode)? If the signal is to pass the diode there has to be a current, and that current has to go somewhere. It won't go into the ...

That's all I need to know. Sounds great! Thanks!
All we need now is that single supply version of the Wasp-filter. Wink

And what is the expected input signal peak-to-peak for this to work well?

/Erik

Haha!

Thanks for the concern and the support, guys! I'm planning a design at the moment that definitely will allow me to build a little, play a lot, build a little, play some more. But I need ...

Ha-ha! Someone has been practicing his swedish, I think! Cool.

Anyway, thanks for all the input, guys. I've come to the conclusion that I won't be including the 4089 in my own Lunetta design. ...

Hi!

Does anyone know how you would go about to use this chip as an ADC, as the datasheet suggests?

/Erik Forsling

Eeeh. Aren't we talking analog comparators then? Or could I somehow make a 4-bit ADC using a 4-bit binary comparator? I don't see how.

But I definitely have to add a couple of analog comparators. ( ...

Aaah. I see. Good thinking.
Ok. I have to add one of those as well.
Still don't see why you would want the comparer, but now I'm sure there's a good reason to add one of those as well! Smile

I've ...

Hi,

I'm wondering about a couple of the suggested blocks. What good are the 4 Bit Adder and Binary Comparator, other than as pieces of combinational logic that might give some unexpected(?) result. ...

Thanks for the input, and thanks for pointing out that thread to me. Good reading.

Good point about HOW to normalize simple gates as well. Should have thought of that.

However, I'm starting to ...

Hi!

I've just started reading about these Lunettas and I feel very inspired by the whole idea. So I'm planning a Lunnetta-in-a-box-sort-of-thing and I'm thinking about the possibility to normalize ...

Yes, they are. Or actually is a sort of analog decay envelope. But there are two main problems with these signals.
1. The level is set by the internal, individual volume per instrument. Level = 0 =& ...

Tried that. LE must be on always. If I toggle that with the strobe signal I get a constant high - until I stroke another pad that is. I would need a way to reset the outputs.

Hi there!

Thanks for the warm welcome. This is great! Really interesting thoughts in your reply.

First of all, I think you're right about the measurements. I wasn't quite sure it would even be p ...

Hi,

I'm new to this forum, and to electro-music in all. Seems like a really nice place.

Now, I'm doing some circuit-bending on a TR505, and among other things I want to add individual gate outpu ...
