Here's a new board-synth design that is going to be used for some upcoming workshop events - build your own drone'n'noise machine. The schematic and design will be shared imminently on the BugBrand Electronics page (once I do up a pdf document for the workshop teaching).
This design features: 3 oscillators - two of which can be sync'd to Osc1 resulting in very rich harmonic drone sounds. Each osc has a switch for hi or lo pitch. The Oscs are all running at audio-rates (rather than the sub-audio clicks of the PostcardWeevil) Mixer and comparator to bring together the Oscs and give a stable output level even when starved. The starve also has two settings - stable and unstable. CMOS overdrive with tone contol and drive setting. 13 touch points! 10 dials! 7 switches (well, 6 if you discount the on/off switch) 1/4" jack output and/or onboard mini-amp.
Results? Power drones and chaoscillations. Touchy-screamy! (Demo sounds coming soon)
Time to build - pretty quick - hopefully people with little or no experience will be able to build these (and learn something about what's going on too) within 4 hours or so. (maybe being optimistic?!)
Workshops are currently booked for Berlin (24th May at PickledFeet) and then in Lisbon at the UM festival sometime mid-to-late June (exact date TBC - via New Interfaces). Get in touch via the main BugBrand site if you'd like to book a workshop for your area...
