Title: sine and triangle waveform calibration?
Post by: bartleby on July 20, 2013, 11:01:03 am
hi everyone, i'm new here. i picked up a minibrute yesterday. love the overall design, sawtooth animation and metallizer are really great additions to the otherwise classic layout, and the filter, well it certainly is different, etc etc.

but i immideately heard that something seems to be wrong with the (sub osc) sine and (main osc) triangle waveforms: there are some very noticeable, sawtooth-like hamonics there that don't belong in a sine/triangle.

so i hooked it up to my scope to see what's wrong, and sure enough both the sine and triangle show some strange dents (see pictures attached; sorry for blurry snapshots, but i think you can see what i'm talking about).

so my question is: can these two waveforms be calibrated for better sine and triangle shape somehow? or is this a quirk that i'll simply have to live with?

oops, seems like this has already been answered (http://www.arturia.com/evolution/smf/index.php?topic=7940.0).
so, apparently this is normal behavior.
sorry for asking again. i did try search, but apparently not thoroughly enough.

Just a bit of character to the synth.   ;)

If I raise the metallizer just a wee bit there is a teeny tiny sweet spot where most of the harmonics disappear.
At least so it is on my brute.
Try it!
