Vintage oscillators, function generators, filters, and other test equipment, repurposed as a giant synthesizer and integrated with my other studio gear, all patchable.  Most from the mid 60s, some older, some newer, with plenty of vacuum tubes. All of these produce amazing sounds with great character (some with a little funkiness).
