Set Synth to Scatter

A Roland System-1 sound bank designed for unearthly audio contortions that only the little green machine can provide. Let loose your arp and get ready for slice & dice!

Scattered sonics are combined with classic melodic arpeggios and effects. Whilst the System-1 has been superseded by its big brother, the System-8. The System-8 dropped the scatter function to probably appear a more “serious” synthesizer. I find the scatter to be more interesting than at first glance because it affects synth parameters, as opposed to DSP scatter effects on the TR-8 and TB-3. I took advantage of this feature and added randomisation to many of the sounds in the sound bank.

There is something for everyone here, with some beautiful bells and softer sounds, to some more random and aggressive patches.

I created these sounds with the Roland Cloud plugin version and have tested them with my hardware System-1. As I don’t have access to a System-1m rack version, I would presume there would be some differences due to the fact the System-1m doesn’t have an arpeggiator or the scatter function.
