The most complex modulator is you. The Planar 2 puts macro control over six outputs—including a quad panning mixer—into your hands with a buttery smooth joystick. Record up to 30 seconds of your own movements, stretch it or mangle it with scan mode, use a trigger for playback, or just loop it—synced or not. Add yourself to your patch.
With its smoothly responsive precision joystick, Planar2 facilitates hands-on vector control of two entirely independent sets of outputs (quadrants A-D, and axis X/Y), plus the ability to capture and playback your gestures. Recording your joystick movements enables the creation of organic and complex envelopes, wild and wobbly LFOs, or extended sonic evolutions. It mixes, morphs, routes and pans audio inputs; triggers gates; outputs control voltages and is itself, CV-controllable. Planar2 puts the ‘joy’ back in ‘joystick,’ and the ‘fun’ back in ‘function generator.’ Its multitasking and tactile interface makes it a flexible and unique control device, no matter what your musical genre.
Vector control of two independent sets of outputs: one quadrant-based (outputs A, B, C, D) and one dual-axis based (outputs X and Y).
X/Y Controller: two-axis CV generator sends either unipolar (0V to +10V) or bipolar (-5V to +5V) signal out the X and Y outputs.
Four Quadrant Controller: With nothing connected to inputs A-D, outputs A-D become joystick-controlled individual unipolar (0V to +10V) control voltage sources.
Quad mixing & crossfading: Vector mixing and crossfading of four independent inputs (A, B, C, D) to either individual outputs or the mixed output.
Quad panning: connect a mono source to Input A and use the joystick to pan it to any of the four outputs. Connect a stereo signal to Inputs A and C and pan it forward and backward in quadraphonic space.
Quad routing: Send audio to Input A and patch outputs A-D to four different processors (i.e. VCF, wavefolder, delay, etc.), then use the joystick to dynamically route the signal through the different effects.
Gate Generator: Generate gates either manually (by pressing the Manual Gate button) or automatically whenever the joystick is in motion.
CV Gesture Recorder: Record joystick motions (including gates) to play back either as 1-shot complex function generators or as looped, LFO-like functions. Start time and length can sync to an external trigger, and punch-in/out recording is supported.
External CV Inputs: In addition to its built-in joystick, Planar2 has two CV inputs, which allows external CV control of quadrant outputs A-D and axis outputs X/Y. A mode switch alters how CV affects these outputs, allowing for some advanced automation techniques (such as circular and spinning motions) that would otherwise be difficult to automate.
The circuit is based in part on the Roland SH-101 / System100m design with several enhancements.
Manual GATE buttons
Three timing ranges: (1 second, 10second, 1minute A/D times)
Normal and inverted outputs
End of Decay (EOD) logic output
Cycle mode (which GATE logic control)
Retrig input (allows re-triggering of the envelope if source gate held high)
Dynamic control of the envelope output level (each ADSR is routed through a linear VCA and the control is normalled to +5V via the LEVEL jack. You can patch another control source like an LFO or VELOCITY level from a keyboard to this jack.
Erica Synths DIY Modulator is 35mm deep, skiff friendly, has solid mechanical construction and doesn’t require wiring.
The Modulator essentially is LFO with simultaneous triangle and square wave outputs, clockable S&H with external CV input and noise source. A kit comes with two versions of noise generator – simple, transistor-based and more complex Zener diode-based one. Latest provides perfect, full spectrum white noise.
LFO with triangle and pulse wave outputs
Choice of transistor-based or Zener diode-based noise generator for massive, full spectrum white noise
The core of the Envelope Generator is borrowed from famous Russian synth Polivoks, but significantly updated schematics – eurorack standard positive gates, envelope amplitude, inverted envelope output, looping feature (looping on gate on). Bonus feature Gate Delay – the module outputs delayed gate signal after Attack stage. Chain up several (4-5) Envelope Generators, each with delayed gate to create evolving polyphonic synth-like pads!
