Crunchy Who’ was the last one by the way.

But, in a totally different vain, here is an attempt to be as faithful as possible - up until the Doctorin The Tardis drums kick in - but the twist is, the tune is being synthesized live by a £4 Raspberry Pi Zero, with a 99p USB audio interface thingie. Description (lifted from my SoundCloud page) -

This track has 8 Virtual Analog monosynths, one wavetable synth (polysynth but with polyphony set to 1 as I am somewhat lax with the noteOff messages throughout!) and a single sample replay synth for the Tardis takeoff effect.

The VAsynths are :
Channel 1 : kick/tom - noise, bandpass filtered slightly resonant, and an EG to shape the amplitude
Channel 2 : snare (same setting as 1 but up the scale)
Channel 3 : the old faithful 'Martyn Ware Glitterclap' - these 3 are not exactly canonical but I wanted to add in a blast of "Human League do Gary Glitter / Doctorin the Tardis" for the outro. This is a burst of noise modulated by a square wave LFO, shaped by an EG to become a decaying train of noise pulses, bandpass filtered and quite resonant to emphasise the clappiness
Channels 4 and 5 - a pair of Radiophonic Wobulators, sin waves which warm up (some Phase Distortion, some morphing to slightly square) under a slow ramping EG, which also ramps up the LFO amplitude that is FM and AMing them. These have a bend range of +- 24 semitones for the giant 2 octave swoops
Channel 6 - the diddly dum bass riff. This is really velocity sensitive, both in amplitude and in brightness. OSCB gets louder under velocity, and both OSCs sharpen up under hard bashing - the 'fine pitch' modulation output is hooked into a fast EG. So really hard hits sound like plucked strings, sharpening immediately under tension then going true very quickly
Channel 7 - bass slurp for the grace notes - a slightly less bright version of the riff, and with a larger reverb send amount to distance it
Channel 8 - is a noise generator and bandpass filter with resonance to be played manually (hence hamfisted noises throughout), with heavy feedback delay to add SFX swishy whooshy things - really spacey, dude!
Channel 9 - wavetable synth for the 'melodica' melodic notes
Channel 10 - EXTERMINATE! Samples, for the heck of it

Plus 4 delays with low pass filters and independent LR delays, levels and feedback levels, plus a stereoizing reverb engine.

Can you believe it - 10 synths, 8 of them virtual analog, on £4.99 of computer hardware. 2016 is an insane place to be.
