Fabric 70 has released Explorer, a free 4-oscillator synth plugin that looks to give you plenty of sound-shaping options.
Oscillators 1 to 3 can each access sine, triangle, sawtooth and square waveforms, while oscillator 4 is reserved for noise. There’s also a waveshaper, a filter section with multiple types, extensive modulation facilities (including three LFOs) and three envelopes.
You don’t get any effects, but Explorer looks like it could take you to some interesting sonic places. It’s available for PC and Mac in VST/AU formats.
Find out more and do the download thing on the Fabric 70 (opens in new tab) website (page is in Japanese).
