One single cycle sine only competition could be seriously cool.
You could use the no sample, DC offset and tuned ring mod alongside because technically still only one’s single cycle sine sample.
Also could tune the sine to harmonics like zer0fly’s example here :https://forum.renoise.com/t/tuning-samples-to-harmonics/49162
Was a bit of a joke. In theory all waveforms are made of sines.
