[sdiy] Continuously variable waveshaping (was Behringer Neutron)

[Ian Fritz]

Another common example is in the Saw - Tri converter.  I use a 741 there to get rid of almost all of the spike that you get.  Filtering doesn’t work there — it mostly just smears the spike out, making it sound worse.

There are plenty of examples in the stompbox world where people prefer the rubbish old slow op-amps over more modern “hi fi” options because the limited slew rate reduces the “edginess” of the high frequencies. Effectively, you’re adding a bit of roll-off.
