Neo Trinity is a 6-channel compact modulation hub offering great musical complexity achievable with simple gestures. Each of the 6 channels can be an LFO, envelope generator, or a CV knob recorder, while their main parameter can be automated using the REC button.

The ultimate automatable modulation hub

Each channel also includes a recordable trigger generator with an algorithmic fill feature to spark inspiration or create polymetric patterns, keeping your patches constantly evolving. Use the SHIFT button to change modulation shapes and sync selected or all channels to an internal or external clock.

Neo Trinity is designed with performance in mind, featuring channel mutes and the ability to store entire presets as banks.

Easy to control with complex possibilities

While the core mechanics of the module are straightforward, the addition of assignable CV inputs exponentially increases the module’s behavioral complexity. Control some or all channels in different ways with the META IN and use the dedicated E and F inputs on channels. These inputs can control the main parameter positively or inverted, control output amplitude, and act as an external trigger or a trigger for the internal Sample & Hold function. The CV knob recorder mode also functions as a quantizer, and combined with the CV inputs, it becomes a useful voltage processor.

Features

• 6 independent channels, each configurable as LFO, ENV, or CV
• Channel indication
• Unipolar (0–5V) or bipolar (-5V to +5V) mode per channel
• LFO shapes (with smoothing): sawtooth, triangle (sine), ramp, pulse, random (smooth)
• LFO range: 260 seconds to 180 Hz
• LFO sync (RATE knob sets divider)
• ENV shapes: decay, attack, variable, pulse
• ENV range: 1 ms to 8 seconds
• ENV retriggerable or non-retriggerable
• ENV slew limiter mode (or AHR envelope with gates)
• CV mode with quantization (ON/OFF, 8 scales, 2V or 5V range, smoothing)
• All modes feature automatable RATE knob and trigger sequences
• Independent automation length per channel (2–64 steps)
• Clock-quantized or non-quantized trigger recording
• Algorithmic trigger fill generator (6 algorithms with knob parameter)
• Mute per channel
• Memory for 6 banks (all settings and automations)
• Clock Reset input for automation (can be turned OFF per channel)
• CLK channel for setting tempo or dividing/multiplying external clock
• Internal CLK generator range: 35 BPM to 420 BPM
• CLK IN and CLK OUT connectors
• META IN CV input – assignable independently to some or all channels
• Channels E and F have dedicated CV inputs
• All CV inputs have adjustable functions: positive/negative and attenuated RATE modulation, bipolar VCA at channel output, TRIG input (slew input), Sample & Hold (for triggered stepped waveforms)
• Firmware updates via USB-C
• User calibration of outputs and inputs (for quantizer precision)
