The IF112 is a stable, wide-range 1V/Octave VCO with incredible sonic versatility. The [BANK A] and [BANK B] pots let you 'create' a 10-stage waveform. Now imagine these waveforms, each with a precisely stepped 6-octave range control, that can also be externally voltage controlled.
The [HF OUT] is the actual core frequency of the VCO which then goes through 2x 'divide-by-10' sections ('BANK A' and 'BANK B') to create the [OUT A] and [OUT B] outputs. Conceptually, the IF112 is a 2-channel 10-step sequencer able to run from sub-sonic through to sonic. The [BANK A] and [BANK B] controls let you 'draw' each cycle of the wave from 10 consecutive steps (each being 10% of the total wave shape), with each step having a variable step height from 0 to 100%.
Add to this, two unique, new types of sync, a funky digital ring-modulator type input, plus separate linear and exponential FM inputs.
The outputs [OUT A] and [OUT B] can be switched to output either a 'wave' output (signal is centred around 0V) or a 'CV' output (signal is always in the positive sector and nevre goes below 0V).
Pedro Eustache talks about and demonstrates his Analogue Wind Synthesiser (using the IF112 Double Deka as the VCO core) Quote: "The IF112 performs PERFECTLY for my modified Karplus-Strong analog application [in fact, it is basically an analog equivalent to the NI' Reaktor "Steam Pipe" ensemble, by Martijn Zwartjes], which I play from a vintage Lyricon Wind Driver (analog wind synth controller) from the late 70's".
