This video, zibbybone, captures a meeting of the Roland System 100M – a vintage modular from around 1979 – and the new Roland AIRA System-1M Eurorack semi-modular synthesizer. 

Video summary:

This video is mostly about controlling an external LFO via keyboard CV and have it modulate filter, amp and pulse width. The first clip is 100M’s LFO modulating 1M’s filter. 2nd clip showcases the 100M’s VCO through the 1M’s filter.

Both of these clips also feature TR-8 rhythms and sequencing from the Arturia MicroBrute. Last clip demonstrates external LFO from 100M modulating the 1M’s amplifier section.
