When opening the Wavetable Synth Machine you will land on page 1 of tab 1. Use the first 2 tabs to configure the wavetable oscillator and the sub oscillator + noise generator.
Use Tab 3 to configure the Filter section and Tab 4 to configure the Amp section.

The wavetablefilter oscillator tab (Tab 1)section has 3 pages containing different controls. When a Tab header displays small bar icons, click its corresponding button underneath to jump between its pages.

On any Tab in the Wavetable Synth Machine, the encoder is used to select wavetables in the current folder. Click the encoder to load other wavetable folders.
When turning the encoder (or the Position knob), a dedicated display will pop-up, showing the name of the wavetable, the position you're in, the number of waves in the wavetable and a wave display. This screen will stick for a couple of seconds, but you can lock it it if you press button 4, labeled "Lock". Use knobs 2 and 3 will adjust the X and Y axis of the wave display to your liking. Knob 1 will alter the wavetable position.

Wavetable Oscillator tab

There are <exact number?> factory wavetables, licensed with Galbanum (https://www.galbanum.com/)
These wavetables are 16-bits, 2048 samples per wave.

You can also load custom wavetables using the SD card.
The oscillator will read 32-bits wavetables but play them in 16-bits. It will function with 2048, 1024, 512, 265 and 128 samples wavetables.
User wavetable have to be put in folders, anywhere on the SD card. You can't mix different sample formats within a folder, and the folder name has to end with "_XXX", with XXX being the sample format of the waves in the folder. For example "MyCustomWavetables_1024" if the wavetables are in the 1024 samples-per-wave format.

The wavetable oscillator tab has 3 pages.


Page 1:

Filter 1 Frequency	Filter 1 Resonance	(Filter Morph) -or- (Filter Gain)	Filter 1 Type
Controls the filter's cutoff frequency	Controls the filter's resonance amount	Morph between the filter types, from Low-Pass to Notch to High-pass. This parameter is only available when the filter type is set to SVF for State Variable Filter. -or- Set the EQ gain when the filter type is set to Bell Eq	Select a filter type and slope. Read the chart below for details on every filter available. This parameter cannot be modulated.

Page 2 is the same as page 1, but controls Filter 2. In order to unlock it, you need to have the Routing on page 3 on a setting other than Single.

Page 3 allows for filter routing options:

Routing	Balance between filter 1 and 2	-	-
Select a routing configuration for the filters. Single enables only filter 1. Serial routes the output of Filter 1 to Filter 2. Para will route both filters in parallel Split will split the sound sources into the two filters, depending on the Machine select.	Controls the volume of both filters at the output. Fully clockwise only filter 2 will be heard, and fully counter-clockwise it will be only filter 1.	-	-
