Neural DSP's latest Quad Cortex update adds new amps, effects and more

If you own Neural DSP's Quad Cortex not only do you have the benchmark multi-effects and amp modelling processor right now, but you are also getting more goodness with every generous update. And the new CorOS 1.4.0 is no exception.

Nine new guitar amp models, three overdrive pedals, 10 new effects and the highly-anticipated Minivoicer algorithm are the headline additions here. Hang on, what's a Minivoicer? 

It allows players to add two pitch-shifted voices on top of one’s signal. 'The voicing library provides control over the root note, modes, and chords for harmonising as well as arpeggiating,' states Neural DSP. 'Activate MIDI to harmonise one’s DI signal to the MIDI-instructed pitch allowing users to harmonise to chord changes.'
