[sdiy] harmonic generator

[mark verbos]

Now you lost me. What is a windowing function? You mean to make the 
attack/delay "curve"? I imagine the combination of amplitude and weak 
lopass filtering is also very responsile for the "Bichla sound". FM of 
course as well, since resonant filtering is the flagship sound on most 
other syths.

My new obsession is the Buchla 248. With a bigger one, you could have a 
synth with no other control modules. This one doing ALL the sequencing, 
enveloping (AD,AR,ADSR or multistage), LFOing and combinations of these. 
It is the greatest use of space and front panel controls I can think of. 
This thing can even do things you wouldn't think of like switching 
between 2 external (or internal for that matter) sources. IMHO someone 
should explore marketing a digital modular, with analog patching. The 
part that always sucks about digital is the menus. If you make it look 
like an analog modular, but behind use digital cicuits, crazy new things 
could happen. What do you say Grant? Wiard 400 series? ha. would they be 
green panels? make that digital frequency shifter you talked about. 
While you are at it, replace some of those hundreds of chips in a Buchla 
MARF with a PIC or Microprocessor or PLA or whatever and make it a new 
product. just some thoughts. keep on rocking and rolling.
