What is the values for pure saw and square waveforms?

Hey

What is the values for non crossfaded/morphed osc waveforms?

also - where can I set the resolution more precise for parameter values?


Thanks

a dialed in pure saw/square/etc. is not exactly the same from machine to machine (correct anyone?)- my OSC2 is a hair counterclockwise from the dial indicators, OSC3 is pretty spot on, OSC1 is similar to OSC2- I use my ear, but muscle memory works when mid-song tweaking…

I use my ear too to distinguish waveforms.

The Voyager being first and foremost an analog instrument, the values at which you will obtain a perfectly non-crossfaded waveform will vary from unit to unit somewhat.

As for the resolution, internally the Voyager knobs have 14 bits accuracy (16384 possible values), but only displays 8 bits on its display (256 values). The only way to set more precise value for a parameter is to physically move the knob very slowly, or send MSB and LSB values directly via MIDI. Otherwise, via the “up” and “down” arrows on the panel you can only set 256 values (each equivalent to 64 knob steps).

An oscilloscope is very useful to visualize quickly a waveform and get a precise sawtooth, or square out of a variable waveform oscillator design. Although by ear is also relatively easy too.

Using your ear is the fastest method.
Its very easy to get your ear used to how pure sawtooth or pure pulse should sound. Because the crossfaded waveforms clearly differ soundwise from the pure waveforms, you’ll find the pure waveforms very fast, if you know how they should sound.

Quickest way to find them is to use VCO3 in low frequency mode and assign it as a modulation source to filter cutoff at max resonance. As you sweep the waveform knob you will hear the waveshape you want.
