Neo Trinity

Bastl Instruments

Capabilities 5

CV Sequencer (Chain)cv-sequencer
6 independent channels can each record knob movements and create pitch/gate sequences. Automation sequences of 2–64 steps, with clock-quantized or non-quantized recording and algorithmic fill generators.193
Clock Sourceclock-source
Internal clock generator with 35–420 BPM range, tap tempo, and CLK IN/OUT for external sync. Supports clock division (up to /8) and multiplication (up to x4) with odd-factor substeps.193
Envelope Generatorenvelope-generator
6 independent channels can each be set to ENV mode with 4 shapes (decay, variable, attack, pulse), retrigger control, slew/AR mode, and 1ms–8s range.193
LFOlfo
6 independent channels can each be set to LFO mode with 5 shapes (saw, triangle/sine, ramp, pulse, random), smoothing, sync to clock, and rate range of 260s to 180Hz.193
Quantizerquantizer
CV mode includes a quantizer with 8 scales, 2V or 5V range, and smooth interpolation option. Can process external CV via META IN or IN E/F inputs.193

Jacks 7 — 5 in / 2 out

NameSignalVoltageDescription
Inputs (5)
CLK INclockReceives external clock. Maximum accepted frequency is 50Hz. When connected, module operates in external CLK mode as divider/multiplier.193
IN Ecv193
IN Fcv193
META INcvAssignable CV input affecting some, none, or all channels. Multiple input modes: regular, regular attenuated, inverted, inverted attenuated, VCA, TRIG, and Sample & Hold. Updated at 4kHz.193
RESETtrigger193
Outputs (2)
CLK OUTclock0V to 5V193
Channel Outputs (A-F)cv-5V to 5V6 channel outputs updated at 4kHz. Bipolar mode: -5V to +5V; unipolar mode: 0V to +5V. LEDs indicate voltage polarity and intensity (green=positive, red=negative). Can be calibrated for V/OCT accuracy.193

NameTypeRangeBehavior
Automation Lengthmenu_setting2steps – 64steps193
CV Quantizationmenu_settingToggles quantization ON/OFF and selects from 8 scales. D button toggles quantization, A selects major/minor, B&C combinations select scale type. More lit buttons = more notes in the scale.193

ENV Durationmenu_setting1ms – 8000ms193
ENV Shapemenu_setting193
Input Modemenu_setting193
Internal CLK BPMmenu_setting35BPM – 420BPM193
LFO Ratemenu_setting0.00385Hz – 180HzControls the speed of the LFO from 260 seconds per cycle up to 180Hz. When synced to clock, the RATE knob sets the clock divider.193
LFO Shapemenu_setting193
MODEbuttonCycles through LFO, ENV, and CV modes for the selected channel. In the CLK channel, starts/stops the clock. Also used to cycle through input modes when held with channel buttons.193
RATEknobSets the main variable of the selected channel: LFO speed (or clock divider when synced), envelope duration/shape, or output voltage in CV mode. Can be automated by holding REC and turning the knob. Turning the RATE knob after recording offsets the recorded sequence; center position maintains original automation.193
Unipolar/Bipolarmenu_settingSets each channel output to bipolar (-5V to +5V) or unipolar (0V to +5V). Note: in ENV mode, envelopes are always unipolar and cannot be switched to bipolar.193
