Additional distortion and compressor stages are provided for beefing up signals, and FXpansion's TransMod modulation system lets you animate Etch's circuits over time. Use inter-modulating LFOs, envelopes and more to drive the filter cutoffs, distortion level, compression amount or any other parameters. Etch does amazing things to all kinds of audio material and is great for subtle warming, deep tone sculpting, wild sweeps, special effects and experimental sonics.
