Have a listen to some of these sample snippets recorded from Motas-6 (with external reverb/effects on occasion). Some of the more unusual sounds were created using the 'randomise' patch feature.
'u strings 1' - a nice string example
'j strings 1'
'techno bass on w'
'techno bass' - using arpeggiator
'nin' - industrial noise
'twinkle toe'
'puk' - odd...
'road rage'
'elec'
'complex sync' - multi oscillator sync
'n strings'
'git' - pulse-width modulation.
'd* default'
'birds' - random sample and hold
'30303' using the arpeggiator, single VCO
'303032' listen for the sub-square added at the end
'motas5 acidify' (sorry, bad quality recording here)
