Go2-X: Analog-Modeled Morph Synth by Rob Papen

The morph oscillator is the centerpiece of Go2-X. You select a First and Second Waveform (Wave-A and Wave-B) and choose how they combine, with morph modes including Mix, Morph, Partial Morph variants, Table Interpolate, Table Split, Table Combine, FM, PM, AM, Ring Mod, WaveShaper and Range. A Spread control creates a stacked two-oscillator sound, and a symmetry control with its own modulation LFO lets the waveform shape change over time.

The main filter is analog-modeled and offers two comb filter types and ring modulation. Cutoff can be modulated by velocity, key tracking, the modulation wheel or the filter envelope. An additional high-pass filter sits behind the main filter, with its own cutoff, resonance and keyboard tracking controls.

The 12-way modulation matrix routes internal sources such as envelopes and LFOs, along with MIDI controllers including pitch bend, aftertouch and other standard MIDI messages, to parameters across the synth. Two free LFOs and two free envelopes provide additional sources, and several sections can sync to tempo.

The XY pad works as both a live control and a programmable modulation source. You can record and edit paths with up to 128 points, quantize them to a grid and loop them in several modes. The arpeggiator offers up to 16 steps with per-step tie, slide, velocity, unison and chord settings, plus a sequencer mode and ratcheting.
