The Synthi brought a lot of new sound design possibilities thanks to its modular aspect and its pin modulation matrix.
Please check the below instructions on how to use it.
Don't forget that any source can be patched to any destination, which can lead to feedback loops.
In case you want to experiment with those, the usage of a limiter is recommended.
Due to the technology used in the original Synthi, it wasn't possible to modulate the modulation amounts.
However, the group assign feature resolves this limitation and lets you modulate any modulation amount assigned on the Matrix.
From this panel, you can modulate each groups independently, by assigning them a modulation source and defining a modulation amount.
Ring modulation mixes two waveforms and outputs the sum and difference of the frequencies present in each waveform.
It's pretty similar to Amplitude Modulation with one significant difference:
Ring Modulation lets the sound go through both when the carrier/modulator value is positive and negative.
(With Amplitude modulation, the sound cuts when the modulatior value is inferior to 0.)
Still, the Sample and Hold can sample its values from various sources like oscillators, or control voltages, or even a combinate of multiple sources.
Additionally, it is possible to draw some joystick motions from the advanced panel.
(Note: the advanced panel lets you modulate parameters that are not on the Matrix)
The right panel lets you edit the global parameters, whereas the lower part lets you edit each individual point coordonates and time division.
