Aurora AR-57 synthesizer

The Aurora AR-57 has been around in various forms over the last few years. Firstly, the pre-production models were called the AR1, which had 2-pole low and high pass filters, and OTA oscillators. There was briefly an AR51, but the only difference was a panel layout. The up to date version AR-57 has the same features, but now uses a 4-pole low/high pass filter, transistor based oscillators, military spec. components, plus Germanium transistors for the mixing circuitry.
