Bazille: How to perfectly pitch-track LFOs?

[themagicalkamja]

In the Bazille Tips and Tricks thread on KVR, someone left the following description for how to turn LFOs into chromatic oscillators:

-connect LFO1 triangle or pulse wave into Out1
-set the rate to 0.1s and the dial to 3.04 (or 4.04 for +1oct) to later be in tune with the other oscs.
-select CV1 as mod source for the rate and value it to 2.67
-pick a multiplier and patch the key1 into two inputs (or patch into one input and daisy-chain into the 2nd)
-patch the mult out into CV1 in.

I tried this and it does indeed work perfectly, but with settings like 3.04 and 2.67 and doubling KeyFollow into the multi, this method seems so convoluted and arbitrary! By contrast, most things like this in Bazille are much more principled and sensible. For example, increasing the filter cutoff knob by 12 increases the cutoff by an octave. Makes perfect sense!

In hopes that the method for turning LFOs into chromatic oscillators would be equally straightforward, I (1) set LFO1's centered rate to 0.1 seconds, (2) used the rate knob to tune it to the desired root, then (3) modulated the rate by KeyFollow and set RateMod to 5 (i.e., 100%). But while this got close, it was NOT perfectly chromatic, since hitting keys an octave apart produces notes less than an octave apart.

So with all that background out of the way: Is the quote above truly the best/only way to turn LFOs into extra oscillators, or is there a simpler, more elegant way to do it? I couldn't find my answer in the manual. Any advice appreciated, thanks!

The filter is intended to be a filter. LFOs are not intended to be audio rate oscillators. The fact that you can turn them into audio rate oscillators is a testament to the flexibility in Bazille.

As for the complexity, there is a reason. KeyFollow is based on MIDI note number, which is linear. Note pitch is exponential. The LFO runs at control rate. But CV allows you to inject audio rate into it. You need the multiplexer to do the conversion, and the values mathematically work out to translate MIDI note to frequency.
