The Instruō tòna is an all analogue voltage controlled oscillator. tòna generates all four classic waveforms with the addition of a fifth output driven by a built in all analogue wavefolder. The wavefolder is derived from the classic West coast “timbre” circuits and opens a world of rich harmonics and complex spectra, adding a touch of West coast flavor to any subtractive synth voice.

Features:

• Sawtooth core analogue oscillator
• 1V/octave, Coarse and Fine pitch controls
• Oscillator hard sync
• Linear FM with attenuator
• Individual outputs for Sine, Triangle, Sawtooth and Square waveforms
• CV controllable ‘timbre’ wavefolder with dedicated output

Specifications:

12HP
Depth: 27mm

+12V: 40mA
–12V: 40mA

Note: This is a used item, and while it is guaranteed to be fully functional it is almost sure to also contain "rack rash" on the mounting holes and have some minor scratches on the panel from use. It will include a ribbon cable, m3 screws, and a box, but not the original box.
