condition: like new
make / manufacturer: Blue Lantern Modules
model name / number: JPJFET VCO
MODEL: BLM JPJFET VCO
Analog Saw Core VCO
Width: 6hp
Depth: 1 Stack PCB. Skiff Compatible.
Current: -32mA, +35mA
Circuit type: Analog

What does this do?
This is a fully analog Voltage Control Oscillator that is Saw core based...unlike many VCOs which are triangle core. It uses a JFET part inside to generate
the Saw wave. This is very similar to a famous Roland Vintage product, but this is using modern equivalent parts.
The 1V per Octave circuit is also not transistor based. It is using a modern VCA circuit for 1v/octave tracking.


Wave Outputs: Saw wave, Pulse Wave. Both are operating from 0v. -5v/+5v (AC signal)
Pulse Wave has a Pulse Width Modulation input.
Saw Wave is static, and the PWM does not do anything to it.

Modulation Inputs: Linear, and Exponential.
1. Modulation with Attenuator. Exponential Type.
2. Linear with Attenuator.
3. 1V/Octave Direct Input.

Hard Sync Input.
This requires a Positive Square Wave.
Softer AC wave forms will do a very soft sync effect.
