This Bitwig tutorial segment shows how to push a custom-built arpeggiator patch into stereo territory using two distinct techniques inside The Grid. Because every signal in The Grid is natively stereo, the LFO driving the entire patch can be split and manipulated independently per channel.
The first approach uses a phase offset on the right channel. Shifting phase pushes the right channel's entire signal chain slightly behind or ahead of the left, so the same frequencies and pitch relationships play out of sync. Setting the offset to 180 degrees puts the two channels in exact opposite phase.
The second approach uses the Left/Right Gain module from the Mix category to set a different amplification level per channel. Because the LFO waveform is smaller on one side, it passes through fewer pitch values and triggers notes less often, effectively slowing down the arpeggiation rate on that channel. Boosting the gain on the other side increases activity and can push the signal beyond the 0-to-1 pitch scale boundary.
The result is two channels running at genuinely different speeds and densities, not just offset in time. Combining both methods gives fine control over how wide and how varied the stereo field becomes.
