Octatrack: No Samples Necessary - Comb Filter Synthesis

No samples needed for this tutorial; the Octatrack can act as a rather fascinating synthesizer as long as you know how to get your hands on plenty of extra gain.

0:50 white noise generation
2:25 white noise amplitude envelope
3:06 filter pings
3:30 comb filter pings
4:31 excitation shaping
5:43 impulse modulation
7:16 noise shaping
8:26 chorus
9:40 additional triggers
11:36 additional comb filter
12:57 white noise waveform display
13:37 chorus modulation
14:17 comb filter detune modulation
15:04 distortion on excitation filter
16:00 different track lengths
16:47 re-sampling source
17:59 audio editor display quirk
19:11 panning modulation
20:08 lo-fi FX for re-sampling channel
21:04 excitation filter modulation
22:01 disabling excitation filter distortion
22:18 cue bus attenuation
22:55 mix change-up
23:45 re-sampling channel filter modulation
24:31 flanger on re-sampling channel
25:05 reducing comb feedback
26:22 closing remarks

note: sending a short burst of white noise into a tuned delay line with high feedback (i.e. a comb filter) is also often known as 'karplus-strong synthesis' and is frequently used to simulate bowed or plucked string sounds, such as guitar and violin
