Patch Notes: 

’Pinging’ the Pip Filter with its special ‘Trig’ input to create a plucky analog wood block / conga style melody, taken further with filter FM from the Pip LFO.

A fast x4 trigger is patched from Pamela’s PRO Workout to the ‘Trig’ input of the Pip Filter. The frequency is lowered and resonance is increased until it is just at the edge of self oscillation, producing a classic percussive ‘ping’. A V/Oct pitch sequence from Pam is then patched to the Frequency input, producing a simple rising melody reminiscent of the warm analogue wood block or conga sounds of vintage drum machines. Next, the square wave out of the Pip LFO is patched to the first frequency input of the Pip Filter, with very slight inversion to modulate the melody. The resonance is subtly increased to lengthen the ping and the Pip LFO is switched into VCO mode, introducing audio rate FM to the filter frequency. The Pip Slope is then patched to sweep the frequency of the FM and the filter frequency is manually increased, producing high pitched chaotic bursts of analogue filter FM. 

The new Pip LFO and Pip Filter join the Pip Slope, offering a compact but flexible group of modules great for adding functionality to a system with tight space or combined as a unique 12hp analogue synth voice.
