31  Using Arduino / Audio / Re: MIDI Reset on: June 22, 2013, 03:04:43 pm
I'm not sure that's the correct all notes off command.
32  Using Arduino / Audio / Re: MIDI Reset on: June 22, 2013, 02:03:05 pm
If a note on an external device is tuck, you have send something to stop it. Resetting your arduino device won't change that.

What did you have in mind?
34  Using Arduino / Audio / Re: MIDI Reset on: June 22, 2013, 02:52:56 am
some things send all notes off command. other things send every note with a velocity of 0.

There's usually a .7v drop, emitter to collector.
36  Using Arduino / General Electronics / Re: pot wiring on: June 21, 2013, 09:17:17 pm
That can be changed in software easily enough.  I'm thinking that you want the lowest amount of voltage to the wiper when pot is all the way down. Seems most logical that way around, so pin 1 to gnd.
37  Using Arduino / General Electronics / pot wiring on: June 21, 2013, 08:48:33 pm
Is there an accepted standard for pot wiring?

Is it:
pin1 5v
pin2 wiper
pin3 GND

or:
pin1 GND
pin2 wiper
pin3 5v

Any reasons?

Most of us - especially us working in real production- have to use large US distributors like Digikey, and that's what I based my pricing on.

I'd guess a coil and a cap are under $2.
40  Using Arduino / General Electronics / Re: Filtering 5V and 12V in a noisy automotive environment on: April 07, 2013, 11:07:41 pm

Sure, but a DC-DC converter will cost a lot more.
41  Using Arduino / General Electronics / Re: Filtering 5V and 12V in a noisy automotive environment on: April 07, 2013, 08:52:41 pm
An inductor, in series, and a 1200uf 35v cap to GND after that is what I've seen used for 12v filter.

Would be nice to see a full sketch that does some audio effects.

This is interesting. What might you use this for? Are there audio examples?
44  Using Arduino / Audio / Re: Velocity Sensitivity with non-MIDI Keyboard on: March 26, 2013, 01:49:15 am

I'm curious what velocity sensitive keyboard you have that does not have MIDI.
45  Using Arduino / General Electronics / Re: resonator vs crystal on: February 23, 2013, 07:37:14 pm
16th are time divisions, not pitch.

While you say to "just do it", measuring timing accuracy isn't that straightforward.. How would you do it?
