Contour 1 by Joranalogue

Features

• Analogue voltage controlled bidirectional slew limiter.
• Precision circuitry to slew any signal, including pitch CV, accurately.
• Separate rise/fall slope bending with voltage control and compensation for minimal effect on slew time.
• Real-time visual feedback through LEDs on slew time sliders.
• Dedicated gate input in addition to the analogue slew input: easily create +10 V attack-release (AR) envelopes, regardless of the gate amplitude.
• Trigger input and push button: reset the slew core and trigger a one-shot attack-decay (AD) envelope through a single trigger signal.
• Voltage hold gate input 'freezes' the slew core. Pause envelopes and LFO modulations, or create pulse-width-sensitive sync sounds at audio rates.
• Impedance-compensated regular and inverted analogue outputs.
• Rise and fall status gate outputs.
• Loop switch for variable waveshape temperature-stable VC(LF)O operation. Gate input functions as an oscillation enable input in loop mode.
• Capable of 1 volt/octave tracking over several octaves.
• Wide slew time range: 500 µs to 30 seconds per slope. Audio range switch setting constricts range to ease tuning.
• V/octave trim potentiometer accessible from the front panel.
• Highly multifunctional: slew limiter, envelope generator, envelope follower, (gated) VC(LF)O, frequency divider, slope detector and much more.
• Precision-milled 2 mm anodised aluminium front panel with high-resolution, non-erasable graphics.
• Size: 8HP
• Depth: 30mm
• Power: +12: 90 mA, −12: 85 mA
