This is a demo of a vintage Maplin 5600s analog synthesizer.
In the early 70’s, the Australian magazine Electronics Today International published Tervor Marshall’s designs for two partly digital, mostly analog, Electronic Music Synthesisers. the ETI 3600 and ETI 4600.
Both were made available as kits of components. Barry Wilkinson at ETI was responsible for the final packaging and kitting coordination. Maplin Electronics Ltd.(in the UK) subsequently picked up the designs, which they marketed as as the Maplin models 3800 and 5600s Electronic Music Synthesizers.
This sequence is based on his two transient trapezoid envelopes. It’s a very nice matrix synthesizer with many parameters …much more than an EMS VCS3. His Matrix has 30 x 30 contact points (900 in total) for complex I/O and control voltages. It has a built in spring reverb and an amazing cv controlled phaser. The “kick” come out from a RSF Kobol driven by the Maplin 5600 trigger.
