reading the LTC 1799 it talks about a Voltage Controlled mode::
Figure 4 shows the LTC1799 configured as a VCO. A voltage source is connected in series with an external 10k resistor.
The output frequency, fOSC, will vary with VCONTROL, that is the voltage source connected between V+ and the SET pin. Again, this circuit decouples the relationship between the input current and the voltage between V+
and SET; the frequency accuracy will be degraded. The oscillator frequency, however, will monotonically increase
with decreasing VCONTROL
https://cds.linear.com/docs/en/datasheet/1799fc.pdfThat seems like an interesting potential function for a vibrato add in for the LTC1799 clock
What confuses me is that it draws in the circuit diagram (Figure 4 in the .pdf) the clock source as a + - device, like an LED or capacitor, but i'm only used to thinking of CV like a input pin on a 555 oscillator.
Could i make a 555 oscillate between 0-1.13V to create an LFO vibrato?? hmm.
