Portland

Percussion synthesizer

The Portland percussion synthesizer has been designed as a drum machine companion to the FSS Brunswick. Like the Brunswick, Portland has been designed with affordability and flexibility in mind, allowing for a wide range of drum synthesis options from relatively sparse electronics. Portland is presented as a “sandbox” for percussion and drum synthesis, giving several different analogue sound generation and shaping elements in a patchable unit. The synthesis elements are normalled together on the patchbay, allowing for minimal patching to arrive at a kit of drum sounds, however this normalling can also be overridden for more complex drum sound synthesis. There are 32 Patch points in total, see further down the page for the full list.

Drum synth circuit elements:

Bass Drum semi-linear resonator
2x Twin-T resonators
“Ring” generator, formed from 6 XOR’d oscillators
Noise generator
Dynamic hi-hat shaping circuit
2x decay envelope generators
2x discrete audio VCAs
Four channel audio mixer with Baxandall tone circuit
