yes, after years and years of development, for your creative pleasure...

a shitty synth that sounds remarkably like a casiotone home keyboard.

totally terrible synth patch, but the 'pianokeys' subpatch might come in useful.

I love the waveform generator, and yeah it sounds like a casio PT20, one or two up from the VL afair. Makes a nice bass synth with a bit of chorus. I think you'd call that PWM (pulse width modulation), or just call it square wave synthesis, (and there's a method working out the spectrum using Walsh instead of Fourier equations I beleive). The way I remember my VL-tone you had to program it by typing a 20 digit number into the calculator or some hack like that and you could only tell the difference between the trumpet and the piano because everything everything else sounded the same.
ahh happy memories. Have you got a midi file of "da da da" by Trio?

>> Have you got a midi file of "da da da" by Trio?

no, please post one if you have it.

i have a casio pt280, and this patch recreates the piano and trumpet sounds uncannily.

but i really want to nail the vibraphone as well. i think it might need a bit of additional fm or something.

if i refer to the same subpatch from two different othe rsubpatches, does pd then open the first patch two times? or does it know that it is already open?

If it's an abstraction yes, but not for subpatches afaik, for those each new instance takes up more space and is a separate bit of code.

by the look of geraeuschtest's post, it looks like they are confusing subpatches with abstractions...

but anyway, in both situations pd would have to load the code twice. otherwise it would be impossible to have different data flowing through different abstractions. wouldn't it?

I wish I knew more about the internals of Pd to say for sure, but in theory no, code can be reenterant, meaning the same code can be reused in more than one place "simultaneously" (the stack gets saved of course to remember state).
Actually, I have no idea if Pd does this, but I had a feeling if it does then it only can for
abstractions. Frank would probably know, so let's ask on the list.

thanks, i try to understand what you say. actually right now the difference between subpatch and abstraction is not very clear to me but i will find out...
the thing is there was a subpatch with f.e a delay line and a dac~ in it. as it was loaded twice the volume went up and it got kind of out of control...
