The Yamaha AN1x Synthesizer mailing list

The AN1x is very versatile as you know. It can generate a lot of
aliasing for example. To get analog sounds you should avoid that with
the Edge control of the VCOs. I have tested it with the excellent free
vst plug-in Frea(k)oscope from smartelectronix.

To get all aliasing components up to 15kHz below -70dB relative to the
fundamental I found these upper limits for the Edge value:

<Fundamental> Hz : <Edge value>
125  Hz : 105
250  Hz : 95
500  Hz : 85
1000 Hz : 75
2000 Hz : 65
4000 Hz : 55

As a rule, Edge values below 80 will remove a lot of aliasing.
