The effect on a standard organ known as a Leslie created by a spinning motor creates a Doppler effect, the effect can be heard in acid rock songs such as the Pink Floyd song "On the Run". does your organ have one of these?

No, there was no Leslie speaker in it. Everything was solid state except the reverb.

on a second note, would you ever be willing to release the schematics/Rom of that midi board? I'm thinking of making a chipophone myself.

I'll think about it. The code might need a little cleaning up first. =)

My father has built pipe organs for 30 years now and has also lectured on solid state electronics at the university for 25 years. I found a free electric organ in my neighborhood and we are seriously considering taking on a project like this. Would you release the schematics/Rom of that midi board?

Thanks for all the videos Linus, your hard work is well enjoyed by everyone.

Again though, I'm going to shamelessly bug you for the code. Please release it ;_;

Linus, so why did you go with 1volt peek-to-peek?
Some monitors provide support for 1V peak-to-peak signals,
but they are not standardized.
So why not 0.7v in your calculations?

Option: Using two 2R's in parallel to make the R's
And a there are less R's than 2R's,
so less waste than putting two R's in series to make 2R

How about nice demo-style-text-scroller in this video? ;-)

Thanks Linus - a really interesting talk.

Your comments about the "famichord" made me wonder: to what extent are chip tunes is influenced by Japanese music? That chord (minor[no 5]m7) is quite reminiscent of the pentatonic minyo scale, and I couldn't help noticing that all the composers on the famichord demo are Japanese.

An interesting experiment if you have a piano synth is to set the number of channels low (mine does 2 and 4, but not 3) and see how this influences your playing style. Its surprising how much you can do with few voices, and how the ear seems to "retain" notes that only sound momentarily.

What exactly make his description pretentious? That he seem to be interested and enjoy many different things from an array of different fields? Or that he's better than you at most of those stuff?:P

I believe the reason for having 12 oscillators was that there was a school of
thought in the 70's (I'm old enough to remember :] ) that it sounded better if the adjacent notes where "free phase" - i.e. not locked in sync with each other. Dividing down the semi-tones from a single oscillator was perceived to produce a "flatter", less complex sound.
Of course, the hard-core elite insisted that meant that you should have a separate oscillator for each key on the keyboard. However, for most purposes one for each note and dividers for the octaves was sufficient and saved a lot of time tuning.
