Due to popular demand the Triangulum VCO will be back in stock early 2019 !!! you can stop asking now please 😉
The omsonic Triangulum is an extremely solid triangle core analogue eurorack VCO with excellent temperature stability, tracking over 7+ octaves and lots of nice features in a small 10HP footprint.
What’s special about it ?
The Square wave
Unlike most other eurorack VCOs the square wave pulse width is calibrated to exactly 50% meaning it sounds similar to a lot of classic synths that used this technique such as the Roland System 100m for example.
The Saw wave
The saw wave has a switch associated with it that lets you select between a regular saw or a saw that is an octave above the other waves.
The tuning system
Below the octave switch is a “freq” knob that can be used to tune the VCO over 2 octaves. The freq knob is connected to 3 indicator lights “5th, +1, +2” these aid in quick tuning by lighting up when the VCO is at +7 semitones (a 5th), + 1 octave and + 2 octaves.
The triangulum makes use of onboard voltage regulators meaning the VCO will have the same calibration characteristics in every system it is used in, this also helps with stability.
