CV Trinity - Wood Panel

Bastl Instruments
A live performance powerhouse, the Bastl CV Trinity provides 6 different tempo-synced voltage-controlled modulation sources with excellent hands on control!

CV Trinity has 6 independent channels with CV outputs, each of which can be set to AUTOMATION, LFO or ADSR. Each channel also has a CV INPUT. The selected output [select OUT] outputs a copy of the channel that is selected for editing and lights the indication LED. Use SELECT buttons for selecting the channel and knobs for adjusting its parameters. Pressing the mode button changes between the modes. Clock OUT can be adjusted by holding select button and turning the top knob. Clk OUT is normalized to Clock IN.

Automation is 32 step voltage memory with adjustable amount of linear interpolation. Hold the record button and turn RECORD knob to adjust the automation curve. Clock input advances to next automation step. Automations can be variable number of steps and can be clocked either by master clock input or by individial CV inputs.

LFO has RATE that goes up to audiorate, XOR waveshaping and SHAPE selection with ramp, triangle, inverted ramp, flopping ramp, flopping triangle and stepped random voltage source with smoothing. The random signal can be looped. LFO can by synchronized to clock input (different divisions/multiplications are than set with the RATE knob). CV input controls the RATE of the LFO.

ADSR uses the CV input as GATE input for triggering the envelope. It can be linear or exponential, it can be looped and it can either work in ADSR mode or AHR mode. DECAY is set to the same value as RELEASE.


  • 6 independent modulation channels that can be set to AUTOMATION, LFO or ADSR
    • AUTOMATION: clocked 32 step memory with adjustable linear interpolation, number of steps and possibility of independent clocking.
    • LFO: rate, XOR waveshape, shape (ramp, inverted ramp, triangle, flopping ramp, flopping triangle, stepped random with smoothing and looping), synchronisation with clock.
    • ADSR: attack, sustain , decay set to same value as release, linear or exponential, looping mode, attack-hold- release mode.
  • CV input and CV output per channel
  • Select OUT jack outputs the currently selected modulation channel - excellent for live jamming!
  • Indication LED for select OUT
  • Jumpers to select 0Ì´Ì_ÌÎ̝ÌÎÌÕ5V or 0Ì´Ì_ÌÎ̝ÌÎÌÕ10V range for each CV input

Current Consumption: +12V: <5mA, -12V <5mA, +5V: <35mA
