Limitation) and it doesn’t have a great Influence on the sound but it’s better than nothing.
In the Mode-Rout section you can easily select between different filter types: (LP=low pass,
HP=high pass, BP=Band Pass). The filter outputs are additive so there is an option to create
other types of filter like LP+HP=Notch, HP+BP and etc ….
3OFF is not a filter type it’s just a SID feature that Mutes the oscillator 3 sound before
It reaches to the filter.
(OSC1-OSC2-OSC3) are Oscillators bypassed switches. For example with selecting OSC1 the
output of the oscillator 1 goes directly to master output without any filtering and this is the
same for OSC2 and OSC3. EX is the bypass switch for external audio signal.
Curve :
applies logarithmic or linear curve over filter frequency value in any range .
Keytrk :
sets the key tracking amount for modulating the filter cutoff . For example, it
makes filter cutoff higher as you play higher notes on the keyboard or lower as you play
lower notes.
Veltrk :
sets the velocity tracking amount for modulating the filter cutoff. For example, it
makes filter cutoff higher as you play notes harder.
About the external signal:
SID chip has an input pin for routing external audio signal to the
filter, this input pin is one of the noise sources of the SID. In HyperSID hardware this pin is
connected to the ground for rejecting the noise but still a little amount of noise is audible on
the output. Sometimes with enabling or disabling the EX switch you can achieve less noise
so it is left there just for noise cancelation.
LFO
LFO is a software based module with many capabilities
that acts like a traditional LFO .
On- Off switch
disables or enables the LFO function.
Top dropdown list
determines LFO wave shapes
including: (Sin, Saw, Tri, Sqr, Noise) .
Speed
determines the LFO frequency (0- 60Hz).
Depth
determines the amount of the LFO amplitude
and In the negative side it inverts LFO output.
Sync
synchronizes LFO frequency with host tempo.
4/4
determines LFO frequency in Sync mode (16/4, 8/4, 4/4, 2/4, 1/4, 1/8, 1/16, 1/32).
Retrig
retriggers the LFO when notes are played.
Bottom dropdown list (Routing)
shows modulation destinations including (fil cut, pw1, pw2,
pw3, pw1+2, pw1+3, pw2+3, pw1+cut, pitch1, pitch2, pitch3, 2).
