ARP 2601 is a Windows 64 Bit VST3i (no Apple Mac).
As the name suggests, the synth specializes in quickly building more complex waveforms using a couple of layers of Phase Modulation (think FM). There is also a nice 12 dB Low Pass Filter and a couple of Envelopes. It is a very simple but effective engine with a slant toward some of the earliest digital synths.
The architecture is deliberately simple. You can use the device to create waveforms for other synth/samplers or modulate any of the controls in real time for a more complex patch using the mod system built into most modern DAWs.
